Inflation: A Comprehensive Briefing
Inflation: A Comprehensive Briefing
Summary
Inflation is an increase in the general price level of goods and services, corresponding to a reduction in the purchasing power of money. It is a fundamental economic concept with far-reaching effects on households, businesses, and national economies. Measured primarily by price indexes like the Consumer Price Index (CPI) and the Personal Consumption Expenditures (PCE) price index, the inflation rate reflects the annualized percentage change in these indexes.
The causes of inflation are multifaceted. The modern consensus, often referred to as the triangle model, attributes it to three core factors: demand-pull inflation, where aggregate demand outstrips an economy’s production capacity; cost-push inflation, resulting from supply shocks that increase production costs (e.g., oil crises); and built-in inflation, driven by self-fulfilling expectations of future price increases. Historically, the quantity theory of money, which links inflation to an excessive growth in the money supply, has been a dominant explanation, with economist Milton Friedman famously stating, “Inflation is always and everywhere a monetary phenomenon.”
The effects of inflation are mixed. Negative consequences include the erosion of real income for those on fixed payments, increased uncertainty that discourages savings and investment, market inefficiencies due to distorted price signals, and hidden tax increases. Conversely, moderate inflation can have positive effects, such as enabling the labor market to adjust more quickly, providing central banks with more room to maneuver monetary policy to avoid recessions, and encouraging investment over money hoarding. Most economists and central banks today favor a low, stable, and predictable rate of inflation, typically around 2%.
Historically, the United States has experienced several significant inflationary periods. The most severe occurred during and after World War I, with prices more than doubling. A subsequent surge followed World War II due to pent-up consumer demand. The defining macroeconomic event of the latter 20th century was the “Great Inflation” from 1965 to 1982, when inflation peaked at nearly 15%. This period was caused by a combination of factors, including a policy focus on maintaining low unemployment (the Phillips Curve tradeoff), the collapse of the Bretton Woods system, fiscal imbalances from war and social spending, and major oil shocks. It was ultimately conquered by the stringent anti-inflationary policies of Federal Reserve Chairman Paul Volcker, which induced a severe recession but successfully re-anchored inflation expectations. More recently, the COVID-19 pandemic triggered the highest inflation in four decades due to global supply chain disruptions and a surge in consumer demand.
The primary responsibility for controlling inflation is typically given to central banks. The modern approach is inflation targeting, where the central bank uses monetary policy tools, chiefly the adjustment of interest rates, to steer the economy toward a specific inflation goal.
1. Defining and Measuring Inflation
Core Concepts
In economics, inflation is a sustained increase in the general price level of goods and services in an economy over a period of time. When the price level rises, each unit of currency buys fewer goods and services, leading to a reduction in the purchasing power of money.
Several related concepts are critical to understanding inflation:
• Deflation: The opposite of inflation, representing a decrease in the general price level. While falling prices may seem beneficial, deflation is often associated with economic stagnation, as consumers delay purchases in anticipation of further price drops.
• Disinflation: A decrease in the rate of inflation. Prices are still rising, but at a slower pace.
• Hyperinflation: An out-of-control inflationary spiral, sometimes defined as inflation exceeding 50% per month. Historical examples include the Weimar Republic and Zimbabwe.
• Stagflation: A combination of high inflation, slow economic growth, and high unemployment, as experienced in the U.S. during the 1970s.
• Core Inflation: A measure that excludes volatile components like food and energy prices to provide a clearer view of underlying, long-term inflation trends. Central banks, including the Federal Reserve, pay close attention to this metric.
Primary Measurement Tools
Inflation is quantified using price indexes, which track the average price of a representative “market basket” of goods and services.
| Index Name | Description | Key Features & Purpose |
|---|---|---|
| Consumer Price Index (CPI) | Measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services. Published by the Bureau of Labor Statistics (BLS). | The most widely used measure of inflation. The basket is mostly fixed and updated periodically. It is used to make cost-of-living adjustments (COLAs) for wages, pensions, and government benefits. |
| CPI for All Urban Consumers (CPI-U) | A broad CPI measure covering approximately 93% of the total U.S. population. | Reflects spending patterns for all urban households. |
| CPI for Urban Wage Earners and Clerical Workers (CPI-W) | A narrower CPI measure covering households that derive more than one-half of their income from clerical or wage occupations. | Used for determining COLAs for Social Security benefits and other federal programs. |
| Personal Consumption Expenditures (PCE) Price Index | Measures price changes for all goods and services purchased by consumers in the U.S. Published by the Bureau of Economic Analysis (BEA). | The Federal Reserve’s preferred measure. Its basket composition changes more quickly with consumer spending patterns, providing a more comprehensive view of inflation. |
| GDP Deflator | Measures the prices of all final goods and services produced domestically. | A broad measure used to adjust nominal GDP to real GDP. It includes non-consumer items like military spending. |
| Producer Price Index (PPI) | Measures the average change over time in the selling prices received by domestic producers for their output. | Considered a leading indicator of consumer inflation, as it measures price pressures on producers that may be passed on to consumers. |
Challenges in Measurement
Accurately measuring inflation is complex due to several factors that can overstate the true cost of living:
• Quality Improvements: A portion of a price increase may reflect an improvement in product quality (e.g., a new smartphone with more features) rather than pure inflation. Statistical agencies attempt to adjust for this, but it is a difficult task.
• New Products: The introduction of new goods provides consumers with more choices and value, which is not immediately captured by a fixed-basket index.
• Substitution Effect: When the price of one good rises, consumers often substitute it with a cheaper alternative. A fixed-basket index like the CPI does not fully account for this behavior, potentially overstating the cost of living.
• Perception vs. Reality: Public perception of inflation is often higher than official measures. This is because consumers tend to notice price increases on frequently purchased items more than price decreases or stable prices on durable goods.
2. The Causes of Inflation
Modern economic thought attributes inflation to a combination of three main forces, often called the “triangle model.”
• Demand-Pull Inflation: This occurs when aggregate demand for goods and services exceeds the economy’s production capacity—often described as “too much money chasing too few goods.” This can be caused by:
◦ Expansionary Fiscal Policy: Increased government spending or tax cuts that boost overall demand.
◦ Lax Monetary Policy: Low interest rates or an increase in the money supply that encourages borrowing and spending.
◦ Sudden Increase in Private Spending: A stock market rally or other events that boost consumer confidence and expenditure.
• Cost-Push Inflation: This arises from a drop in aggregate supply, which increases the costs of production. The impetus comes from the supply side of the economy. Common causes include:
◦ Supply Shocks: Natural disasters, wars, or other events that disrupt production.
◦ Increased Input Prices: A sharp rise in the price of key raw materials, such as the oil shocks of the 1970s. Firms pass these higher costs on to consumers in the form of higher prices.
• Inflation Expectations: The anticipation of future inflation plays a crucial role in its persistence. When people and firms expect prices to rise, they act in ways that make it happen:
◦ Workers demand higher wages to keep up with the expected cost of living.
◦ Firms raise prices to cover anticipated increases in labor and material costs.
◦ This creates a self-fulfilling prophecy or a “wage-price spiral,” leading to inflation inertia. The credibility of a central bank is key to anchoring these expectations.
The Role of the Money Supply
The Quantity Theory of Money is one of the oldest hypotheses in economics, positing a direct relationship between the quantity of money in an economy and the price level. The theory, based on the equation of exchange (MV = PQ), was central to the monetarist school led by Milton Friedman. While most economists agree that long-lasting episodes of high inflation are typically the result of excessive money supply growth, the short-term relationship has proven less stable. In recent decades, financial innovation has weakened the link, with Fed Chairman Jerome Powell noting in 2021 that the once-strong connection “ended about 40 years ago.”
3. Economic Effects of Inflation
Inflation has both negative and positive effects on an economy, which is why most policymakers aim for a low and stable rate rather than zero inflation.
| Negative Effects | Positive Effects |
|---|---|
| Erosion of Purchasing Power: Reduces the real value of money and hurts individuals on fixed incomes, such as pensioners. | Labor Market Adjustments: Allows real wages to fall without cuts to nominal wages, helping labor markets reach equilibrium faster and reducing unemployment. |
| Uncertainty and Discouraged Investment: Unpredictable inflation makes it difficult for businesses to plan long-term, discouraging savings and investment. | Room to Maneuver for Monetary Policy: A positive inflation rate keeps nominal interest rates above zero, preventing a “liquidity trap” where a central bank cannot cut rates further to stimulate a recessed economy. |
| Redistribution of Wealth: Harms lenders and benefits debtors with fixed-interest loans, as the real value of the debt decreases. | Encourages Spending and Investment: Gives consumers and businesses an incentive to spend and invest rather than hoard cash, which boosts economic activity. |
| Market Inefficiencies: Distorts price signals, leading to a misallocation of resources as it becomes difficult to distinguish genuine price changes from general inflation. | Avoids Deflation: Prevents the damaging effects of falling prices, which can lead to delayed purchases, reduced economic activity, and lower growth. |
| “Shoe Leather” and “Menu” Costs: High inflation induces people to minimize cash holdings (shoe leather costs) and forces firms to frequently update prices (menu costs). | Mundell-Tobin Effect: Argues that moderate inflation encourages savers to substitute from holding money to making capital investments, boosting economic growth. |
| Hidden Tax Increases: Can push taxpayers into higher income tax brackets even if their real income hasn’t increased, unless brackets are indexed to inflation. |
4. A Historical Overview of U.S. Inflation
The U.S. economy has experienced several distinct periods of significant inflation, often driven by wars, supply shocks, and policy shifts.
World War I Era: The Highest on Record
The period during and immediately after World War I saw the worst inflation in recorded U.S. history.
• Cause: Massive diversion of economic resources to the war effort created severe shortages of consumer goods.
• Peak: Prices surged more than 80% from late 1916 to mid-1920, with a single-year increase of 23.7% from June 1919 to June 1920.
• Aftermath: To combat runaway inflation, regional Federal Reserve banks sharply raised interest rates, triggering a deep but brief recession from 1920 to 1922, during which prices fell over 15% in one year.
World War II and Postwar Boom
During WWII, inflation was suppressed by widespread rationing and price controls. However, this set the stage for a post-war inflationary spike.
• Cause: The end of rationing and price controls unleashed a “tsunami” of pent-up consumer demand, fueled by years of wartime savings (e.g., war bonds). The economy needed time to transition from military to domestic production.
• Peak: From March 1946 to March 1947, inflation increased 20.1%.
• Context: Despite high prices, consumers purchased millions of cars, refrigerators, and stoves, fueling a period of prosperity.
The Great Inflation (1965–1982)
This period was the defining macroeconomic failure of the post-war era, reshaping economic theory and central banking. Inflation rose from just over 1% in 1964 to a peak of nearly 15% in 1980.
• Motive: Policymakers, guided by the Employment Act of 1946, pursued “maximum employment” under the belief that a stable “Phillips Curve” allowed them to trade modestly higher inflation for permanently lower unemployment. This assumption proved to be false.
• Means: In 1971, President Nixon ended the U.S. dollar’s convertibility to gold, collapsing the Bretton Woods system. This severed the last anchor for monetary policy, allowing for excessive money supply growth.
• Opportunity: Several factors exacerbated the situation:
◦ Fiscal Imbalances: Spending on the Vietnam War and President Johnson’s Great Society programs strained the federal budget.
◦ Energy Crises: The 1973 Arab oil embargo and the 1979 Iranian Revolution caused oil prices to quadruple and then triple, leading to severe “cost-push” inflation.
◦ Bad Data: Policymakers underestimated the natural rate of unemployment and overestimated the economy’s potential output, leading them to pursue overly expansionary policies.
The era ended with the appointment of Paul Volcker as Fed Chairman in 1979. Volcker implemented a painful anti-inflationary policy, aggressively tightening the money supply and raising interest rates. This policy induced a severe recession from 1981–1982, with unemployment peaking near 11%, but it successfully broke inflation’s momentum and restored the Fed’s credibility.
Post-1982 Bouts and the Pandemic Surge
After the Great Inflation, the U.S. entered a long period of relative price stability known as the “Great Moderation,” with two notable exceptions:
• A spike to 6.3% in 1990 after Iraq’s invasion of Kuwait drove up oil prices.
• A spike above 5% in 2008 during the Great Recession, also due to record-high oil prices.
The COVID-19 pandemic triggered the highest inflation in 40 years.
• Cause: A combination of global supply chain disruptions, widespread shortages, and pent-up consumer demand fueled by government stimulus.
• Peak: The 12-month inflation rate peaked at 9.1% in June 2022.
• Response: The Federal Reserve began aggressively raising interest rates in March 2022 to cool the economy and bring inflation down.
5. Controlling Inflation
Controlling inflation is a primary objective of modern central banks. The strategies to do so have evolved over time.
• Inflation Targeting: This is the dominant contemporary strategy. Central banks, like the Federal Reserve, publicly announce an official inflation target (typically around 2%) and use their policy tools to achieve it. This helps anchor public expectations and enhances policy credibility.
• Monetary Policy: The main tool for controlling inflation. By raising interest rates, a central bank can cool an overheating economy and reduce demand-pull inflation. Conversely, it can lower rates to stimulate growth and prevent deflation.
• Fixed Exchange Rates: A country can peg its currency to that of a low-inflation country, effectively importing its monetary discipline. This sacrifices domestic monetary policy independence.
• Wage and Price Controls: Direct government limits on wage and price increases. While used in wartime, they are generally seen by economists as a temporary measure that can distort markets and cause shortages if applied in other contexts.
• Gold Standard: Historically, linking a currency’s value to a fixed amount of gold provided a monetary anchor. However, it was abandoned because it was found to be too rigid, limited a country’s ability to respond to recessions, and subjected the inflation rate to arbitrary fluctuations in gold supply.

5 Surprising Truths About Inflation That Will Change How You See the Economy
5 Surprising Truths About Inflation That Will Change How You See the Economy
Introduction: Beyond the Headlines
Inflation is everywhere. It’s in the news headlines, the political debates, and most importantly, it’s felt every time you go to the grocery store or fill up your gas tank. The concept seems simple enough: the price of everything goes up, and your dollar doesn’t stretch as far as it used to.
But while the effects are straightforward, the economic reality of inflation is far more complex, surprising, and fascinating than most people realize. The story of rising prices is not just about supply chains and interest rates; it’s a story of measurement challenges, flawed ideas, and the powerful role of human psychology. To truly understand it, we will uncover five truths buried in over a century of data—revelations that dismantle common myths and expose the powerful, often invisible, forces that truly shape our economy.
——————————————————————————–
1. The Inflation You Hear About Isn’t the “Real” One
The Official Rate Isn’t the Full Story
How do you measure something as vast as “the general increase in prices” across an entire economy? The answer is: with great difficulty. According to the Congressional Research Service (CRS), statisticians face two major complications that are almost impossible to solve perfectly:
• Quality Improvements: A new smartphone costs more than a model from five years ago, but it’s also a pocket-sized supercomputer. A portion of that price increase is for a vastly better product, not just pure inflation. Statistical agencies try to account for this, but it’s an inexact science.
• New Products: The “basket” of goods and services used to measure inflation is slow to incorporate entirely new products. Things that didn’t exist a decade ago eventually become household staples, but their initial price changes aren’t captured.
Because of these factors, many economists believe that official inflation figures are likely overstated. This means the headline inflation rate that sparks so much anxiety may be consistently higher than the “true” inflation your wallet actually experiences.
Furthermore, there isn’t just one single measure of inflation. The two most common are the Consumer Price Index (CPI) and the Personal Consumption Expenditures (PCE) price index. While you hear about the CPI most often, the Federal Reserve—the institution in charge of managing inflation—prefers the PCE index. Why? The Fed notes that the PCE index “more quickly adapts to changes in spending patterns,” making it a more current and comprehensive measure of how price changes are affecting the economy.
——————————————————————————–
2. A Little Bit of Inflation Is Actually a Good Thing
Why Zero Isn’t the Hero
If rising prices are bad, then surely zero inflation must be the goal, right? It’s a logical assumption that most economists and central bankers reject completely. In fact, they fear the opposite—falling prices—far more.
This phenomenon, known as deflation, is highly undesirable because when people expect prices to fall, they delay purchases. Why buy a car today when it will be cheaper next month? As the International Monetary Fund (IMF) explains, this collective delay grinds economic activity to a halt, reduces income for producers, and can lead to long periods of stagnation, as seen in Japan’s “lost decades.”
This is precisely why policymakers like the Federal Reserve don’t target 0% inflation. The CRS states that the Fed targets a low, positive rate (generally around 2%) to “reduce inefficiencies within the economy while protecting against deflation.” A little bit of inflation acts as a buffer and provides two other key benefits:
• It allows labor markets to adjust more easily. During a downturn, real wages can fall to match economic conditions without employers having to make the painful and morale-damaging decision to cut nominal (dollar-amount) wages.
• It gives the central bank more room to maneuver. Higher inflation means higher nominal interest rates, which gives the central bank more space to cut rates to stimulate the economy during a recession and avoid a “liquidity trap” where interest rates are already at zero.

3. The Worst Inflation in U.S. History Wasn’t in the 1970s
The Real Record-Holder
When people think of runaway inflation in the United States, they almost always picture the 1970s—an era of oil shocks, gas lines, and “stagflation.” While inflation was painfully high then, it wasn’t the worst on record. Not by a long shot.
According to research compiled by HISTORY.com, the most severe inflationary period in American history occurred during and immediately after World War I. The data provides a stark comparison:
• The single largest 12-month price increase happened between June 1919 and June 1920, when the CPI skyrocketed by 23.7 percent. The annual inflation rate for 1920 was 15.6%.
• The peak 12-month inflation rate during the 1970s oil shocks was 14.8 percent, reached between March 1979 and March 1980.
But what made the post-WWI era truly astonishing wasn’t just the spike; it was the whiplash. After peaking, prices then plummeted by more than 15 percent the following year. This boom-and-bust cycle created a level of volatility far more extreme than the persistent, grinding inflation of the 1970s. Economist Steve Reed captures the turbulence of the time:
“The post-World War I period was one of the most volatile in American history in terms of consumer prices. After skyrocketing more than 23 percent in 1920, prices fell more than 15 percent in 1921.”

4. A Flawed Idea Triggered the 20th Century’s Greatest Economic Failure
The Siren Song of the Phillips Curve
The “Great Inflation” of 1965-1982 is described in Federal Reserve historical documents as “the greatest failure of American macroeconomic policy in the postwar period.” This debilitating era wasn’t caused by a single event, but by a perfect storm—a flawed idea that collided with fiscal pressure, a broken monetary system, and an energy crisis.
The central flawed idea was a belief in the Phillips curve—the notion that there was a stable, exploitable trade-off between unemployment and inflation. Policymakers in the 1960s widely believed they could “buy” a permanently lower unemployment rate if they were willing to accept modestly higher inflation. This became a “fateful assumption.”
This idea was given the means to wreak havoc when the global monetary system collapsed. In the early 1970s, the United States severed the dollar’s last link to gold, ending the Bretton Woods agreement. This removed a critical anchor for monetary policy, giving the Federal Reserve more room to make mistakes.
Finally, opportunity knocked in the form of immense fiscal strain from President Johnson’s “Great Society” programs and the Vietnam War, followed by two severe energy shocks in the 1970s. These oil crises created “cost-push” inflation that policymakers felt powerless to control. Trapped by their belief in the Phillips curve, they tried to fight the resulting rise in unemployment with policies that only accelerated the expansion of the money supply. The result was the “worst of both worlds” known as stagflation: high inflation and high unemployment.
——————————————————————————–
5. Your Beliefs About the Future Directly Cause Inflation Today
Inflation is a Self-Fulfilling Prophecy
The disastrous failure of the Phillips curve during the Great Inflation forced economists to confront a powerful truth they had underestimated: one of the primary drivers of inflation is simply the expectation of future inflation. What we collectively believe will happen next directly causes inflation today.
Imagine a factory floor. Workers, hearing news of rising prices, demand a raise to keep up. The factory owner agrees but, to protect profits, raises the price of the goods they produce. This price hike then ripples through the economy, prompting other workers to demand raises. And so the cycle begins. This feedback loop, known as a “wage-price spiral,” shows how expectations become a self-fulfilling prophecy.
This is why central bank credibility is one of the most important tools for fighting inflation. As the Federal Reserve’s own history of the Great Inflation shows, when a central bank is believed to be “tough” on inflation and committed to price stability, it can help anchor expectations. If people believe the central bank will succeed in keeping inflation low, they adjust their wage and price demands accordingly, making the bank’s job easier and less economically painful.
——————————————————————————–
Conclusion: An Economy of the Mind
Inflation is not just a dry metric of supply and demand. It is a deeply human phenomenon, shaped by the lessons of history, the limits of our knowledge, and the power of our own collective psychology. It’s a reminder that the economy is not a machine but a complex system driven by the choices and beliefs of millions of people.
Given that our collective beliefs can shape our economic reality, how might a better understanding of these hidden forces change the way we talk about—and prepare for—the future?

An Economic Analysis of U.S. Inflationary Periods and Their Drivers
An Economic Analysis of U.S. Inflationary Periods and Their Drivers
1.0 Introduction: Defining the Framework for Analyzing Inflation
Inflation is a critical macroeconomic indicator, reflecting the health and stability of an economy. A persistent rise in the general price level erodes the purchasing power of households, distorts investment decisions, and can, if left unchecked, lead to significant economic instability. This analysis deconstructs the major inflationary periods in modern U.S. history by applying core economic theories to historical data. By examining the distinct causes, policy responses, and long-term consequences of each episode, we can build a comprehensive framework for understanding the complex dynamics of price instability.
At its core, inflation is a general increase in the price of goods and services across an economy, which corresponds to a decrease in the purchasing power of money. As prices rise, each dollar buys a smaller percentage of a good or service. Economists and policymakers rely on several key indices to measure this phenomenon, each offering a slightly different perspective on price changes.
Key Measures of U.S. Inflation
| Index | Description and Purpose |
|---|---|
| Consumer Price Index (CPI) | Measures the average change over time in the prices paid by urban consumers for a market basket of commonly purchased consumer goods and services. The CPI is widely used to adjust household incomes, government benefits, and tax brackets for changes in the cost of living. |
| Personal Consumption Expenditures (PCE) Price Index | Tracks the prices of all goods and services purchased by consumers throughout the economy. It differs from the CPI by accounting for substitutions consumers make as prices change, making it a more dynamic measure. The Federal Reserve uses the PCE index as its primary guide for its 2% long-run inflation target. |
| GDP Deflator | Measures the change in prices for all final goods and services produced in the United States, including those purchased by businesses and the government, not just consumers. It is used to convert nominal GDP into real GDP, providing a picture of economic growth without the distortion of price changes. |
Economic theory attributes inflation to a handful of primary drivers, which often work in concert to create upward price pressure. These theories provide the analytical lens through which we can interpret the historical events that follow.
• Demand-Pull Inflation: Occurs when aggregate demand for goods and services outstrips the economy’s production capacity, often described as “too much money chasing too few goods.”
• Cost-Push Inflation: Arises from a disruption to supply that increases the cost of production, forcing businesses to pass higher input costs on to consumers through higher prices.
• Growth in Money Supply (Quantity Theory of Money): Posits that when the supply of money grows too large relative to the size of the economy, the value of each unit of currency diminishes, manifesting as a general rise in prices.
• Inflation Expectations: Occurs when households and firms anticipate future price increases and build those expectations into wage demands and price-setting contracts, creating a self-fulfilling prophecy.
Having established this theoretical framework, we now turn to its application, beginning with the tumultuous inflationary episodes forged by the global conflicts of the early 20th century.
2.0 The World War Eras: Inflation Forged by Global Conflict (1916-1948)
The massive economic realignments required to support the American efforts in World War I and World War II created unprecedented inflationary pressures. These periods were not driven by conventional business cycles but by severe supply-side shocks, as national resources were diverted to military use, followed by explosive releases of pent-up consumer demand once hostilities ceased. The result was two of the most volatile inflationary episodes in U.S. history.
Post-World War I Surge (1919-1920)
The primary cause of the post-World War I inflation boom was a fundamental shift in supply and demand. As the nation mobilized for war, resources were taken out of the non-military sector and diverted to the military effort. This created significant domestic shortages of consumer goods, leading Americans to bid up the prices of the remaining items. This dynamic produced America’s worst inflation on record. Taken as a whole, prices surged more than 80 percent from late 1916 to mid-1920, with the peak occurring in the 12-month period from June 1919 to June 1920, when prices increased by a staggering 23.7 percent.
In response, regional Federal Reserve banks raised their discount interest rates sharply. This aggressive tightening of monetary policy successfully curbed the runaway inflation but induced a monumental economic whiplash. The economy swung from 23.7% inflation in June 1920 to a deflationary crash of -15.8% by June 1921, contributing to a deep but brief recession that lasted from 1920 to 1922.
Post-World War II Rebound (1946-1947)
During World War II, the Roosevelt administration sought to avoid the inflationary spiral of the first war by instituting widespread price controls and rationing. While these measures successfully suppressed inflation during the war years, they created the conditions for an explosive rebound afterward. When the controls were lifted, a “tsunami of pent-up consumer demand” was unleashed upon an economy that needed time to transition from military to domestic production. This severe mismatch between soaring demand and lagging supply drove inflation up 20.1 percent from March 1946 to March 1947.
The extreme volatility of these post-war adjustments eventually gave way to a period of relative calm, but the inflationary drivers of the mid-20th century would prove to be entirely different and far more persistent.
3.0 The Great Inflation: A Paradigm Shift in U.S. Economic Policy (1965-1982)
“The Great Inflation,” lasting from 1965 to 1982, was the defining macroeconomic event of the latter half of the 20th century. It was a period of stubbornly high inflation that saw four economic recessions, two severe energy crises, and the unprecedented peacetime implementation of wage and price controls. Its persistence forced a fundamental rethinking of monetary policy and shattered the prevailing consensus on the relationship between inflation and unemployment.
The origins of the Great Inflation were complex, stemming from a confluence of policy errors, systemic changes, and external shocks. This combination can be understood through a framework of motive, means, and opportunity.
1. Policy Motive: The Phillips Curve: The prevailing economic orthodoxy of the post-war era was that a stable trade-off existed between inflation and unemployment. Guided by the Employment Act of 1946, policymakers came to believe they could “buy” permanently lower rates of unemployment by accepting modestly higher rates of inflation.
2. Systemic Means: The Collapse of Bretton Woods: For decades, the U.S. dollar had been anchored to gold through the Bretton Woods agreement. In 1971, President Nixon severed the U.S. dollar’s final link to gold, ending its convertibility. This act removed the anchor for monetary policy, creating the means for the excessive growth in the money supply that fueled inflation.
3. Economic Opportunity and Shocks: Growing fiscal imbalances from Great Society programs and the Vietnam War strained the federal budget. This was compounded by two severe “cost-push” energy crises: the 1973 Arab oil embargo, which quadrupled crude oil prices, and a second shock in 1979 following the Iranian revolution, which tripled the cost of oil.
The Era of “Stagflation”
The late 1970s produced a phenomenon dubbed “stagflation”—a dismal, “worst of both worlds” scenario combining high inflation with high unemployment. As households and businesses came to expect rising prices, the trade-off between inflation and unemployment broke down. By the summer of 1980, the economic malaise was acute, with inflation running near 14.5% and unemployment over 7.5%.
The Volcker Disinflation
Early attempts to combat inflation failed. The Nixon administration’s wage and price controls created shortages, and the Ford administration’s “Whip Inflation Now” (WIN) program was ineffective. A decisive policy shift occurred in 1979 under Federal Reserve Chairman Paul Volcker. Announcing they would target reserve growth to control the money supply, Volcker and the Federal Open Market Committee (FOMC) engineered significantly higher interest rates to break the cycle of inflationary expectations. The cost was a severe recession from 1981 to 1982, during which unemployment peaked at nearly 11%. However, the policy was a success. By the end of the recession, inflation had fallen to under 5%, and public confidence in the Fed’s commitment to price stability was restored.
The conquest of the Great Inflation was a watershed moment, leading to a new macroeconomic consensus and ushering in a long period of relative price stability that would become known as the Great Moderation.
4.0 The Great Moderation and Post-Pandemic Surge (1983-Present)
The decades following the turbulent Great Inflation were characterized by a remarkable period of price stability, a stark contrast to the volatility that preceded it. This era, known as the Great Moderation, demonstrated the effectiveness of a monetary policy framework anchored by a credible commitment to low inflation. However, this stability was shattered by the recent inflationary shock triggered by the COVID-19 pandemic, presenting a new generation of policymakers with a challenge not seen in 40 years.
An Era of Stability (1983-2019)
The hard-won dividend of the painful 1981-82 recession was a long period of sustained growth and stability. From 1983 to 2019, the U.S. economy experienced steady and mostly stable price growth; from 1991 to 2019, year-over-year inflation averaged just 2.3 percent. This period was not without inflationary pressures, but they were minor compared to previous eras. Brief inflationary episodes occurred in 1990, when inflation peaked at 6.3%, and again in 2008, when it climbed over 5%. Both events were primarily cost-push in nature, triggered by sharp increases in global oil and gas prices that quickly subsided.
The Post-Pandemic Inflation Surge (2021-2022)
The COVID-19 pandemic upended the global economy, creating a perfect storm for a powerful inflationary surge. The causes were a combination of pent-up consumer demand chasing a low supply of goods, global supply chain disruptions, and expansionary fiscal and monetary policy. This combination pushed the 12-month inflation rate to a peak of 9.1 percent from June 2021 to June 2022, the highest level since the early 1980s. In response, the Federal Reserve embarked on an aggressive campaign to tighten monetary policy, raising the federal funds rate by 5.25 percentage points between March 2022 and July 2023 to combat the persistent price pressures.
This recent shock has served as a powerful reminder of the ever-present threat of inflation, setting the stage for reflections on the enduring lessons learned from over a century of managing the U.S. economy.
5.0 Conclusion: Evolving Policy and Enduring Lessons
The history of U.S. inflation is a story of evolving economic theory and policy forged in the crucible of major economic crises. From the supply-driven shocks of the World War eras to the policy-induced stagflation of the 1970s and the recent post-pandemic surge, each period has offered critical lessons that continue to shape modern macroeconomic management. A review of this history reveals three principal takeaways that form the bedrock of contemporary monetary policy.
• The Centrality of Inflation Expectations: The Great Inflation powerfully demonstrated that public expectations about future inflation can become self-fulfilling. This experience cemented the understanding that central bank credibility is its most valuable asset. A firm and transparent commitment to price stability is essential to anchor public expectations and maintain a low-inflation environment.
• The Limits of Policy Trade-offs: The early belief in a stable Phillips curve—suggesting policymakers could permanently trade higher inflation for lower unemployment—was proven to be a “false bargain.” The modern consensus holds that any such trade-off is temporary at best and that, in the long run, price stability is a necessary precondition for achieving the goal of maximum employment, not an obstacle to it.
• The Shift from Direct Controls to Monetary Policy: The historical record shows a clear evolution in the tools used to manage inflation. The use of direct wage and price controls during wartime and the 1970s proved to be temporary fixes that failed to address underlying pressures. The successful disinflation of the early 1980s validated the modern reliance on monetary policy—specifically the management of interest rates within an inflation-targeting framework—as the primary instrument for maintaining price stability.
Today, policymakers face the ongoing challenge of applying these lessons to a complex and unpredictable global economy. The dual mandate to pursue both stable prices and maximum employment requires a delicate balancing act, particularly in the face of global supply and demand shocks that lie beyond the direct control of any single central bank. The history of U.S. inflation serves as a crucial guide, reminding us that vigilance, credibility, and a commitment to long-term stability are the enduring foundations of sound economic policy.

A Student’s Guide to American Inflation: Six Stories of When Prices Soared
1.0 What is Inflation and Why Does It Matter?
At its core, inflation is a general increase in the price of goods and services across an economy over a period of time. In simpler terms, it means your dollar buys fewer goods and services than it used to. This erosion of a currency’s value is often described as a loss of “purchasing power.”
To put this in perspective, an individual would have needed about $355 in 2023 to purchase the same amount of goods and services that $100 bought in 1980.
To track this change, economists and policymakers rely on a key tool: the Consumer Price Index (CPI). The CPI measures the average change over time in the prices paid by consumers for a representative “market basket” of goods and services, including everything from food and clothing to housing and transportation. When the CPI goes up, it signals that inflation is occurring.
Understanding inflation isn’t just about abstract numbers; it’s about understanding the forces that shape the economy and our daily lives. This guide tells the story of American inflation by exploring six key historical periods when prices rose dramatically, breaking down a complex topic into a series of clear, understandable episodes.
Let’s take a walk through more than a century of American economic history to see how these events unfolded.
2.0 The Six Great Spikes: A Walk Through U.S. Inflation History
Major wars, global oil crises, and even a modern pandemic seem like very different events. Yet, over the last century, each of these has played a major role in driving up inflation in the United States, creating distinct periods where Americans felt the pinch of rising prices.
2.1 Episode 1: The World War I Resource Drain (1917-20)
America’s worst bout of inflation on record was a direct consequence of World War I. As the nation diverted vast resources to the military, the domestic economy was starved of essential goods, creating a classic supply-and-demand imbalance. With severe shortages of everything from food to clothing, consumers were forced to bid up the prices of the few items that remained. This was a classic case of “demand-pull” inflation. This wartime pressure culminated in the largest single-year price increase in U.S. history: a staggering 23.7% between June 1919 and June 1920. This was before the Federal Reserve had a unified national monetary policy, and its regional banks responded by raising interest rates sharply. The move successfully curbed inflation but also plunged the economy into a deep, though brief, recession.
2.2 Episode 2: The Post-WWII Demand Tsunami (1946-47)
After years of economic depression followed by strict wartime rationing, Americans were ready to spend. When World War II ended and price controls were lifted, it created a classic case of “demand-pull” inflation, where a tsunami of pent-up consumer demand outstripped the economy’s ability to supply goods. Soldiers returned home, and families who had saved their money and bought war bonds were eager to purchase cars, refrigerators, and other household items. However, the nation’s factories needed time to transition from military production back to consumer products. This mismatch between massive demand and limited supply caused inflation to soar by 20.1% in a single year, from March 1946 to March 1947. The inflationary period resolved itself as the economy’s production capacity caught up, and factories began churning out goods to meet the surge in demand.
2.3 Episode 3: The Korean War Jitters (1950-51)
When the Korean War began in 1950, Americans had fresh and powerful memories of the widespread shortages of World War II. This collective anxiety became a powerful psychological driver of inflation. Fearing a repeat of wartime scarcity, consumers engaged in panic buying, rushing to purchase household goods and non-perishable foods before they disappeared from shelves. This scramble created an artificial surge in demand, pushing overall inflation to a peak of 6.8%, with food prices alone jumping 10%. Unlike the major world wars, however, shortages during the Korean War were never as severe. Because there was less pent-up demand to be unleashed when the conflict ended, the economy avoided another major post-war inflationary spike.
2.4 Episode 4: The ‘Stagflation’ of the 1970s (1965-82)
While the Korean War caused a brief inflationary scare, its end ushered in one of the calmest economic periods on record. For nearly two decades, from the mid-1950s to the late 1960s, prices remained remarkably stable. This “golden age” of predictability, which many came to see as the norm, made the economic chaos that followed all the more jarring. The period from 1965 to 1982, often called “The Great Inflation,” saw the U.S. rocked by two major “oil shocks.” This was the nation’s first major experience with “cost-push” inflation, where the rising costs of a critical input—oil—were ‘pushed’ onto consumers across the entire economy.
• First Oil Shock (1973-1974): The Organization of Arab Petroleum Exporting Countries (OAPEC) declared an oil embargo, which caused crude oil prices to quadruple.
• Second Oil Shock (1979): The Iranian Revolution disrupted oil production again, causing the cost of oil to triple.
These shocks led to stagflation—a “worst of both worlds” scenario combining high inflation with high unemployment and slow economic growth. Overall inflation peaked at 14.8% between March 1979 and March 1980. The era was finally brought to a close in the early 1980s by the aggressive anti-inflation policies of Federal Reserve Chairman Paul Volcker.
2.5 Episode 5: Echoes of Stagflation: The Oil Spikes of 1990 & 2008
After the turmoil of the 1970s, instability in global oil markets would trigger two more shorter, distinct inflationary spikes. These events served as a reminder of how vulnerable the economy was to cost-push pressures from energy prices.
• 1990 Gulf War Spike: Iraq’s invasion of Kuwait in August 1990 caused crude oil prices to double. This shock pushed the U.S. inflation rate to a high of 6.3%.
• 2008 Great Recession Spike: Even as the U.S. economy struggled with a major financial crisis, record-high global demand for oil drove U.S. gas prices to a high of $4.14 a gallon in July 2008. Overall inflation climbed over 5%.
In both instances, the inflationary pressure was temporary. Once global energy prices stabilized and came back down, the overall inflation rate quickly receded.
2.6 Episode 6: The COVID-19 Pandemic Shock (2021-22)
The COVID-19 pandemic caused an unprecedented disruption to the global economy as factories shut down and supply chains ground to a halt. This created a perfect recipe for inflation: a period of extremely low supply was followed by a surge of pent-up demand-pull as pandemic restrictions loosened. In a modern echo of the post-World War II dynamic, this combination produced the highest inflation in 40 years. The 12-month inflation rate peaked at 9.1% for all goods between June 2021 and June 2022. Grocery store prices saw a particularly sharp increase, jumping 11.4% during that same period. In response, the Federal Reserve began raising interest rates significantly to cool demand and bring prices back under control.
These six stories show how different historical forces can lead to the same result: rising prices. Now, let’s synthesize what we’ve learned.
3.0 Learning from History: Recurring Themes
While each of these six episodes was unique, they reveal common triggers that have repeatedly caused prices to soar in the United States. The table below summarizes the key facts from our historical journey.
| Historical Period | Peak Inflation Rate | Primary Cause |
|---|---|---|
| Post-World War I | 23.7% | Wartime resource diversion and shortages |
| Post-World War II | 20.1% | Pent-up consumer demand after rationing |
| Korean War | 6.8% | Consumer panic buying due to war fears |
| The 1970s | 14.8% | Two major oil shocks (cost-push) |
| Gulf War / 2008 | 6.3% / 5%+ | Spikes in global oil prices |
| Post-Pandemic | 9.1% | Supply chain disruption and pent-up demand |
From these stories, three powerful themes emerge:
1. War Major military conflicts consistently disrupt economies. They divert immense resources—from factory output to human labor—away from the consumer sector and toward the war effort. This creates widespread shortages of everyday goods, causing prices to rise as people compete for scarce items.
2. Supply Shocks Sudden disruptions to the supply of essential resources can ripple across the entire economy. The oil crises of the 1970s are a prime example. When the price of a key input like energy rises dramatically, it increases production costs for nearly everything else, from manufacturing to farming. This is often called “cost-push” inflation because the rising costs are “pushed” onto consumers.
3. Demand Shocks Sudden surges in consumer spending can overwhelm an economy’s ability to produce goods and services. The periods following World War II and the COVID-19 pandemic are classic examples. When a wave of pent-up demand is released into an economy that isn’t ready for it, the result is “too much money chasing too few goods,” which leads to “demand-pull” inflation.
Understanding these patterns is the first step toward understanding the policies designed to manage them.
4.0 Conclusion: Taming the Beast
Our journey through America’s great inflationary spikes—from the ashes of world wars to the disruptions of a global pandemic—reveals how vulnerable an economy can be to sudden shocks. In the past, these periods often led to painful recessions as policymakers struggled to bring prices back under control.
Today, the primary responsibility for managing inflation falls to the Federal Reserve, the central bank of the United States. The Fed operates under a “dual mandate” from Congress: to promote both maximum employment and stable prices.
To achieve price stability, the Federal Reserve has an explicit inflation target of 2% over the long run. Economists generally believe that a low, stable, and predictable rate of inflation is good for the economy. It encourages consumers and businesses to spend and invest rather than hoard cash, while avoiding the disruptive economic distortions caused by high and unpredictable price swings.
By studying the history of inflation, we gain valuable context for understanding today’s economic headlines, the decisions of policymakers, and the forces that will continue to shape our economy in the years to come.

Understanding Inflation: A Beginner’s Guide to Prices, Purchasing Power, and the Economy
Understanding Inflation: A Beginner’s Guide to Prices, Purchasing Power, and the Economy
We’ve all felt it: the feeling that the money in your wallet doesn’t stretch as far as it used to. A cart full of groceries costs more today than it did last year. A tank of gas that once seemed reasonable now feels painfully expensive. That feeling is inflation in action, and understanding it is one of the central challenges of modern economics.
At its core, inflation is a powerful force that can destabilize entire countries. Left unchecked, it can destroy savings and cripple an economy, as seen in Zimbabwe’s hyperinflation. But its opposite—falling prices, or deflation—can be just as dangerous, grinding an economy to a halt, as Japan has experienced. The story of economics, in many ways, is the quest to understand and manage this force, seeking a stable middle ground.
1. What Is Inflation?
Inflation is a general increase in the price of goods and services across an economy, resulting in a decrease in the purchasing power of money.
Think of it this way: Twenty years ago, $10 could buy you a movie ticket, a popcorn, and a soda. Today, that same $10 might only cover the cost of the ticket. The dollar amount is the same, but its ability to purchase goods has declined. This erosion of value is the core concept of inflation.
Economists call this diminished value “purchasing power.” When inflation occurs, each dollar you have buys a smaller percentage of a good or service. The impact of this erosion over time can be staggering. For example, according to a report by the Congressional Research Service, an individual would have needed about 355in2023∗∗topurchasethesameamountofgoodsandservicesthat∗∗100 would have purchased in 1980.
To track this change, we use the inflation rate, which is the percentage change in the general price level over a specific period, usually a year. But how exactly do we calculate a single rate for an entire economy filled with millions of different products?
2. How Do We Measure Inflation? The “Basket of Goods”
The most common and widely cited measure of inflation is the Consumer Price Index (CPI). The CPI is calculated by tracking the price of a “market basket”—a collection of several hundred goods and services that a typical household buys. This basket includes everything from groceries and gasoline to haircuts and housing costs. By measuring the total cost of this basket month after month, economists can calculate the overall change in consumer prices.
But you might have noticed that the price of gasoline can swing wildly from month to month, while the price of, say, a haircut, is more stable. Do economists treat them the same? This question leads to a crucial distinction between two types of inflation.
| Category | Headline Inflation | Core Inflation |
|---|---|---|
| Definition | The inflation rate calculated using the entire market basket of goods and services. | The inflation rate calculated after excluding volatile items from the market basket, specifically food and energy prices. |
| What It Shows | Provides a snapshot of the price changes consumers are actually facing in their day-to-day lives. | Helps identify the underlying, long-term trend in inflation. Because food and energy prices can swing dramatically due to temporary events, core inflation gives a less “noisy” signal. |
| Primary Use | Reflects the real cost of living for households. | Used by central banks and policymakers to get a clearer picture of inflationary pressures and guide monetary policy. |
While the CPI is the most familiar measure, other indices exist. The U.S. Federal Reserve, for instance, prefers the Personal Consumption Expenditures (PCE) Price Index. Why? Because, as the Fed notes, “the PCE index is constructed in a way that accounts for how Americans are spending their money at a given time and more quickly adapts to changes in spending patterns.” This makes it a more dynamic measure of underlying economic trends.
Understanding how inflation is measured is the first step. The next is understanding why it happens.
3. What Causes Inflation? The Three Main Drivers
There isn’t one single cause of inflation. Instead, it is typically driven by one or more of the following three economic forces.
3.1. Demand-Pull Inflation
This is the classic scenario of “too much money chasing too few goods.” Demand-pull inflation occurs when the total demand for goods and services in an economy outpaces the economy’s ability to produce them. When consumers, businesses, and governments are all trying to buy more than what is available, prices are bid upward.
A prime historical example occurred after World War II. During the war, production was focused on military goods, and consumer items were rationed. American families had dutifully been buying war bonds for years and were now eager to spend their savings. When the war ended, a tsunami of pent-up consumer demand was unleashed on an economy that hadn’t yet shifted back to producing consumer goods, causing a strong inflationary period.
3.2. Cost-Push Inflation
This type of inflation occurs when the cost of producing goods and services rises. These increased production costs—for raw materials, energy, or labor—are then passed on by companies to consumers in the form of higher prices.
The most famous examples are the oil shocks of the 1970s. The first crisis was triggered by the OAPEC oil embargo in 1973, which quadrupled crude oil prices. The second came after the Iranian Revolution in 1979, which tripled them again. Since oil is a critical input for transportation, manufacturing, and heating, costs rose across the entire economy, pushing inflation to painfully high levels.
3.3. Built-in Inflation and Expectations
This is a psychological driver of inflation that can create a self-fulfilling prophecy. If people expect prices to rise, they will act in ways that cause prices to rise. This often leads to a “wage-price spiral”:
1. Workers expect future inflation, so they demand higher wages to maintain their purchasing power.
2. Businesses, facing higher labor costs, raise the prices of their products to protect their profit margins.
3. Seeing these higher prices, workers anticipate even more inflation in the future and demand even higher wages.
This cycle can lock in inflation, making it persistent. Understanding these drivers is crucial because, when they spiral out of control, they can inflict real damage on savings, incomes, and the very stability of an economy.
4. Why Does Inflation Matter? The Good, The Bad, and The Ugly
While very high inflation is undeniably harmful, most economists and central banks believe that a low, stable, and predictable rate of inflation—around 2% per year—is actually beneficial for a modern economy. The goal is to avoid both the damage of high inflation and the dangers of its opposite, deflation.
The Bad: Negative Effects of High Inflation
• Erodes Savings: Cash saved in a bank account or under a mattress loses purchasing power over time. If the inflation rate is 5%, the real value of your savings decreases by 5% each year.
• Hurts Fixed Incomes: Individuals on a fixed income, such as retirees receiving a pension that isn’t indexed to inflation, find that they can afford fewer goods and services as prices rise.
• Creates Uncertainty: When inflation is high and unpredictable, it becomes difficult for businesses to set prices and plan for long-term investments. This uncertainty can act as a drag on economic growth.
The Good: Positive Effects of Moderate Inflation
• Encourages Spending and Investment: Knowing that money will be worth slightly less in the future gives consumers and businesses an incentive to spend and invest it today rather than hoard it. This stimulates economic activity.
• Helps Labor Markets Adjust: Wages are often “sticky,” meaning employers are reluctant to cut workers’ salaries. Think of a company facing a tough year. Cutting every employee’s salary by 2% would be terrible for morale. But if inflation is running at 2%, the company can simply freeze wages for a year. Even though the dollar amount on paychecks stays the same (nominal wage), the company’s real labor costs have effectively fallen by 2% because each dollar is worth less. This flexibility can help businesses avoid layoffs during a downturn.
The Ugly: Economic Extremes
To understand the risks of getting inflation wrong, it’s helpful to look at the two extremes.
| Economic Extreme | Description | Historical Example |
|---|---|---|
| Hyperinflation | An out-of-control inflationary spiral where prices rise astronomically. Money becomes virtually worthless, and the economy grinds to a halt. | Zimbabwe in 2008 experienced one of the worst cases ever recorded, with estimated annual inflation reaching 500 billion percent. |
| Deflation | A general decrease in prices. While falling prices might sound good, deflation is very dangerous. It encourages consumers to delay purchases, causing demand to collapse, which can lead to economic stagnation and a deep recession. | Japan has struggled with long periods of deflation and near-zero economic growth, a situation central banks work hard to avoid. |
The challenge of navigating between these extremes forced economists to abandon some of their most cherished theories, especially during the great economic turmoil of the 1970s.
5. Two Key Concepts from Economic History
The painful experience of the 1970s—often called the “Great Inflation”—was the central case study that transformed modern economic thought. It shattered one big idea and gave us a new, terrifying word for an economic nightmare.
5.1. The Phillips Curve
First proposed in the 1950s, the Phillips Curve suggested a stable, inverse relationship between inflation and unemployment. The idea was that policymakers could achieve lower unemployment if they were willing to tolerate a bit more inflation. This seemed to offer a permanent trade-off. For policymakers in the 1960s, this was the motive for pursuing expansionary policies; they believed they could “buy” lasting full employment at the cost of only modestly higher inflation.
5.2. Stagflation
The 1970s proved that the bargain offered by the Phillips Curve was a delusion. The cost-push inflation from the oil shocks hit an economy that was already struggling, creating a “worst of both worlds” scenario that defied the old theory: stagflation. This term describes an economy suffering from three problems at once:
• High inflation
• Slow economic growth (stagnation)
• High unemployment
This catastrophic event proved that the stable trade-off of the Phillips Curve was wrong, just as economists like Milton Friedman and Edmund Phelps had warned. The relationship completely broke down. To make matters worse, policymakers were handicapped by bad data; their real-time estimates of the economy’s potential were significantly overstated. They were pushing the economic engine too hard without realizing it, pouring fuel on an inflationary fire and creating the stagflation that challenged everything they thought they knew.
6. Who’s in Charge of Taming Inflation?
In the United States and most other modern economies, the primary responsibility for controlling inflation rests with the nation’s central bank. In the U.S., this is the Federal Reserve (the “Fed”).
The Fed’s main tool for managing inflation is monetary policy, which it implements primarily by adjusting interest rates. Here is a simplified explanation of how this works:
• To fight high inflation, the Fed will raise interest rates.
◦ This makes borrowing money more expensive for consumers and businesses.
◦ As a result, people and companies spend and invest less, which slows down the economy.
◦ This “cooling off” of demand helps to relieve the upward pressure on prices, bringing inflation down.
The Fed, like many central banks, officially targets an inflation rate of around 2%. This target is seen as the ideal balance point: it is low enough to avoid the distortions of high inflation while providing a crucial buffer against the dangers of deflation, which can lead to economic stagnation as consumers delay purchases.
7. Core Concepts Summarized
If you remember nothing else from this guide, hold on to these four key ideas about one of the most powerful forces in our economy:
1. Inflation is the rate at which prices rise, which means your money buys less over time. It erodes the “purchasing power” of currency.
2. It is mainly caused by too much demand, rising production costs, or the expectation of future inflation.
3. While high inflation is damaging, a small and stable amount (around 2%) is considered healthy for the economy. It helps encourage spending and gives the labor market flexibility.
4. Central banks, like the U.S. Federal Reserve, are responsible for managing inflation, primarily by raising or lowering interest rates.
