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

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.

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.

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

The stock market crash of 1929 helped trigger a period of deflation in the United States by creating a drastic decrease in the total money supply. Because of the United States' central role in the world economy, virtually every single country was impacted by the recession.

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 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.

Technological advancements are historically deflationary

Technological innovation can drive down costs and prices for businesses, which can increase real wages for employees. As a result, people have more money to spend and demand increases.

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.

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.

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.

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.

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.

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.

Inflation explained in under 3 minutes

Keep seeing inflation in the news, but don't have a great grasp on what it means or how it works? This overview from 1440 breaks down how economists think about inflation, what it means for the average consumer, and how governments attempt to keep rising prices in check through various policies.

Prices can still feel high even if inflation is slowing

This is partly because a recent spike in inflation raised prices permanently, so even though the pace of price growth has slowed, prices have still gone up for good.

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.

US homeownership rates declined from the start of the Great Recession through 2016

In 2004, the US homeownership rate was 69%. When the bubble popped in 2007, due to a variety of factors (including the prevalence of subprime mortgages) the Great Recession began. Foreclosures increased, as did the ratio of renters to homeowners. In 2016, the homeownership rate was at roughly 63.4%.

An inverted yield curve has preceded every recession that’s occurred in the last 50 years

Prolonged yield curve inversions can predict recessions, but even brief inversions can cause investors to react with knee-jerk reactions.

Dollar stores can have negative impacts on local businesses

When a household name dollar store like Dollar General opens in a small town or local community, neighborhood businesses often lose out on key sales, driving revenue down and putting them at risk of closure. This has led some experts to argue that dollar store chains can cause economic stress, rather than relieve it.

Cheap debt and relatively minimal regulation fueled private equity's expansion

Low interest rates in the 2010s made taking on debt cheap, making leveraged buyouts incredibly lucrative. Private equity firms were able to make large deals quickly, in part because they don't face the same disclosure requirements and shareholder approval processes as public companies. These two factors juiced the growth of private funds.

Some economists argue the national debt is not a critical concern

The US has the largest national debt and one of the highest debt-to-GDP ratios. These vitals have long been considered a sign of poor fiscal health, but economists are beginning to shift their attention to interest rates to evaluate national debt.

Consequences of a bad credit score

A bad credit score can lead to spending roughly $100K more on a typical mortgage. Poor scores also prevent you from getting certain jobs, apartments, and more, hindering you from building wealth in the long term.

Network effects are the economic term for a good or service's popularity

When goods or services become especially popular, firms that provide that good or service become dominant in the market—which can ultimately lead to a monopoly.

US consumers collectively owe more than $1T to credit card companies—almost as much as they owe in auto loans.

US housing costs have risen by roughly 175% between 1991 and 2026—but a growing number of Gen Zers are becoming homeowners anyway. In 2025, 4% of homebuyers were Gen Z, up from 3% the year before.

The first steps to rebuilding your credit score include getting to know exactly what's on your credit report and figuring out how far you are from the '700 club,' or 'good score' range.
