The Great Depression is one of history's most notable periods of deflation

The world's most famous case of deflation happened after Black Thursday

While the details are not fully agreed upon, many economists point to the Federal Reserve's tightening of the money supply as a prime culprit, leading to a significant deflationary spiral.

The US unemployment rate soared to over 24% during the Great Depression, the highest in recorded history.

The Great Depression was an international depression felt far beyond the US

Many countries suffered through a depression in the 1930s that the First World War, the US stock market crash, and an economic downturn in Germany turned into an international crisis.

The story of the Wall Street Crash of 1929

The 1920s in the US "roared" with rapid economic growth after the conclusion of World War I. But in October 1929, the bubbly stock markets crashed dramatically, plunging the nation into the decadelong Great Depression.

'Good deflation' happens when prices naturally track with supply, meaning prices change gradually

This tends to make products and services more affordable and normalizes the standard of living. Bad deflation usually happens when there are sudden changes to either supply or demand. Near-zero [interest rates helped create the real estate bubble that sparked the Great Recession when it crashed](https://www.youtube.com/watch?v=LMo9mD8j7IA&t=91s) Because deflation distorts the value of money, deflation is particularly harmful for borrowers. Low interest rates made it easy for businesses and everyday people to take on enormous debt, which exacerbated the effects of the recession.

Markets have always recovered and hit new highs following crashes

The crash that preceded the Great Depression was the most severe the US has ever experienced. It was 28 times worse than the downturn that followed the Cuban Missile Crisis.

Economists define deflation as a sustained decline in prices across an economy

Deflationary periods are characterized by broad, significant price declines. The Federal Reserve can monitor deflation by tracking prices through price indexes, such as the Consumer Price Index (CPI), which characterizes the average costs for consumers each month.

Falling demand and lower costs of production cause deflation

"Falling demand" refers to anything that changes someone's willingness to spend money on goods and services. Global recessions, fears of a worldwide recession, and a fall in the money supply are all factors that could lead to falling demand. Likewise, lower production costs allow companies to increase production, which can lead to a surplus in supply.

The UK was already in a depression before the US Great Depression took hold

The US Great Depression was felt globally, but the severity and length of different countries’ economic downturns varied. For instance, Japan was the first country to exit its depression.

US inflation can generally be split into to two periods—before and after the Federal Reserve

A central bank itself does not mean significant inflation will occur, but economists generally point to factors like two world wars and the printing of money to finance the US federal deficit as primary drivers of price increases.

The 1929 stock market crash is a defining example of a financial bubble burst

Fueled by margin speculation and intense optimism, stock prices soared to unsustainable levels before collapsing in late October—erasing billions in market value within days.

The Smoot-Hawley Tariff Act—which was passed during the Great Depression with the goal of reviving domestic industry—is among the most famous pieces of economic legislation in US history.

The Federal Reserve fought the Great Recession primarily with quantitative easing and repurchasing agreements.

Communism grew in appeal during the Great Depression

With at least a quarter of the country out of work, some Americans disenchanted with capitalism began looking at alternatives. Watch this five-minute video to learn about communism's growing allure during the Great Depression.

Japan's 1990s deflation followed the country's fastest growth period

The end of World War II ended Japan's isolation in the global economy, prompting what's now called the "Japanese Economic Miracle." From the 1940s to the 1980s, Japanese policy makers enacted ultra-loose monetary policies that pushed a ton of cash into the market and fueled rapid growth. But these policies ultimately helped create a bubble and sent the country into a deep period of deflation.

Stand-up became more popular during the Great Depression

The stock market crash of 1929 caused vaudeville theaters to shutter. Audiences were looking for lighthearted distractions from the country’s financial problems, though, and stand-up became more popular, albeit in very different venues.

COVID-19's shock to employment rates sparked some economists to fear deflation

COVID-19 simultaneously disrupted the supply chain and the labor market. Since the unemployment rate had hit record highs, some economists were worried that the supply chain would recover before the labor market. If that had happened, businesses would have been producing goods, but no one would have been able to buy them because they wouldn't have the disposable income to do so.

What was it like to live through the Great Depression?

Hear the personal accounts of four people who lived through the Great Depression, as told by NPR's Throughline. Listen to this 47-minute podcast episode to get a bit more insight into the countrywide economic crisis and what it meant it for everyday people.

In 2023, the US money supply fell at its fastest rate since the 1930s

The money supply tracks how much cash, as well as electronic funds like savings accounts, is circulating through the economy. And a downward turn can be a bad sign.

Read former Fed chair Ben Bernanke's 2002 speech about preventing deflation

Very low inflation rates in the early 2000s in the United States and a worsening recession in Japan sparked some domestic concern over the threat of deflation. While Bernanke wasn't Chair at the time of the speech, he emphasized the Fed's role in preventing deflation.

Central banking in the US has had a fraught political history

That history includes its doomed early efforts in the First and Second National Banks, as well as its failure to address the worst financial period in US history, the Great Depression.

Disinflation, a decrease in the rate of inflation, is different from deflation

Disinflation happens when prices are still going up, just at a slower rate. Prolonged disinflation is also often accompanied by a recession, making it painful for consumers.

The psychological aspect of deflation makes it difficult for policymakers to stabilize the economy

That psychological aspect is referred to as "the deflationary spiral." When prices start decreasing, people tend to hold on to their money to pay the lowest prices. But as prices start stabilizing, people resist increasing prices. (Some users may experience a paywall.)

The failures of the interwar period made the case for a new international system

After World War I, countries devalued their currencies, raised tariffs to block imports, and seized territory unchecked, with the international community unable to organize effectively to stop them. The result was a global depression and, eventually, another world war.

In the 1970s, the US experienced a period of stagflation

It was characterized by high inflation, slow economic growth, and high unemployment. The crisis was triggered by a combination of factors, including loose monetary policy that spurred excess demand and spiraling oil prices caused by an OPEC embargo in 1973.

One signal that a recession has become a depression? When GDP declines more than 10%

There’s no single definition for recessions or depressions, but both are marked by sustained periods of declining economic activity. Depressions are more severe than recessions.

Inflation was a word before deflation was

The word inflation has Latin roots and technically means an influx of air, first appearing in the English language in the 1890s to describe bike tires. Deflation's first known mention in an economic text was in 1919.

The highest inflation ever recorded in US history was estimated at 30% in 1778, just after the Revolutionary War.

The US has been through 34 recessions since 1854

From 1855 to 2020, the average US recession lasted for an average of 17 months. But in the 20th and 21st centuries, the average recession length has shortened, decreasing to 14 months.

Switzerland's currency is so strong that it could cause deflation

Economic instability in the United States in 2025 strongly benefited Switzerland, where the value of the franc relative to the dollar increased by about 12.7%. In response, the price of imports dramatically decreased, making goods overall much cheaper.

A recession is commonly defined as two consecutive quarters of shrinking GDP, but in practice, these economic phenomena are more complex.

A trade war is an economic conflict where nations impose tariffs or other trade barriers on each other in retaliation for similar actions.

In the aftermath of the 2008 financial crisis, the Fed began a program of quantitative easing

This program injected trillions of dollars of new money into financial markets to stimulate the economy. The move catalyzed an 11-year bull run and was repeated during the pandemic. Experts argue such power could worsen wealth inequality and contribute to bubbles in housing and finance.

There's no single definition of an economic recession, though recessions are commonly identified by two consecutive quarters of shrinking gross domestic product.

How the Great Depression still shapes the way Americans eat

From fortified foods to nutrition labels, the legacy of an early financial crisis lives on in kitchens across the United States. Ethnic foods with their (supposedly) hunger-triggering spices were vilified and considered “stimulants” along the lines of caffeine and so, in their stead came prune puddings, canned-meat stews, and dairy-heavy vegetable casseroles featuring America’s first fortified foods.

The Social Security System was created to protect Americans from economic disasters like the Great Depression

President Franklin Delano Roosevelt’s New Deal created new government agencies and programs in the wake of the Great Depression.

China had an inflation rate of -0.4% in August 2025

As opposed to other G20 countries that are largely struggling with high inflation rates, China is facing deflation. Sluggish growth in the country's once booming real estate market is just one glimpse into the consumer slowdown triggering deflation.

How the Great Depression and end of WWI paved the way for Hitler's rise to power

The end of WWI was triggered by an armistice that blamed the conflict on Germany and required the financially struggling country to pay reparations. This outraged nationalists and ignited conspiracies that Hitler was able to capitalize on, according to this six-minute video. It was during this financial strain that the Great Depression hit.

The Federal Reserve can set interest rates below zero

Interest rates, the cost of borrowing money, are the primary tool the Federal Reserve uses to control inflation. During periods of deflation, setting interest rates below zero penalizes saving, encourages banks to lend more and moves more cash through the economy.

The National Housing Act established the Federal Housing Administration

During the Great Depression, 1,000 homes were foreclosed on per day, and half of the mortgages across the country defaulted. To address this crisis, President Franklin D. Roosevelt signed the National Housing Act. It established the Federal Housing Administration, which is still around today and helps protect lenders and buyers.

The New Deal shifted economic and social authority to the federal government

Franklin D. Roosevelt's response to the Great Depression expanded federal power through economic regulation and social welfare programs, permanently reshaping federalism by shifting responsibility for financial security to Washington while leaving states to administer many of these programs.

The stock market has crashed many times throughout history

Have you ever wondered how long it takes the market to recover after a crash? This chart outlines major stock market dips throughout history and tracks how many days it took for the market to recover.

Key moments that shaped the national debt include the Civil War, both World Wars, the 2008 recession, and the COVID-19 pandemic.

The global economy runs on US dollars, with nearly 90% of international trade in 2019 being processed in US dollars.

The US dollar became the world's reserve currency, backed by gold, after 44 nations gathered in Bretton Woods, New Hampshire, in 1944 with the intention of rebuilding the global economy.

In March 2008, Bear Stearns was the first major bank to collapse in the Great Recession—leading to panic across the entire global financial system.

Inflation is a monetary phenomenon in which consumers see a broad rise in the prices of goods and services across the economy over time

Sustained periods of inflation are often caused by central bank policies including low interest rates or increased money supply. With more money chasing the same number of goods and services, prices tend to rise and the value of a single dollar drops.

Some argue that the rising US national debt has become more important in recent months.

Consumer spending accounts for 70% of America's gross domestic product.
