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

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.

'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.

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.

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.

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 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.

A recession is commonly defined as two straight quarters of shrinking GDP

Recessions are sustained downturns in the economy. They’re significant, widespread, and there’s no single, surefire way to define or predict them.

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.

The Federal Reserve targets 2% inflation

It’s an arbitrary number originating from an offhand comment made by a New Zealand policymaker. The real objective is to maintain predictable prices for businesses and families to plan around while avoiding the dangers of deflation.

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.

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.

The lipstick index is just one niche so-called 'recession indicator'

When consumers think an economic downturn is looming, the "lipstick index" economic theory argues that sales of more affordable luxury items (such as lipstick) go up. Other weird alleged recession indicators include Former Federal Reserve Chair Alan Greenspan's suggestion that men's underwear sales could help predict an economic downturn.

The Federal Reserve follows the health of the US economy by tracking the money supply

That includes all of the physical and electronic money in circulation. It tracks not only US coins and bills, but also the money that moves through bank deposits. The Fed uses metrics called trackers to follow different types of transactions through the money supply.

Student debt has a widespread economic impact

Student debt is no different than the big rent or car payment that comes out of someone’s paycheck every month: Its presence affects that household’s purchasing power. Multiply that household by the 43 million Americans who had outstanding federal loan debt in September 2023, and student debt’s impact becomes considerable.

Watch Ray Dalio explain how the economy works

Dalio describes the economy as a machine that runs on three main cycles: productivity growth, the short-term debt cycle, and the long-term debt cycle. Dalio says layering these three cycles on top of each other essentially creates a template for understanding changes in the economy.

Bond yields are the returns investors earn from their bond’s interest—and they're a key economic barometer

Bond yields are considered a major indicator of how the US and global economies are doing, and where they’re headed. When bond yields increase, this tends to mean the cost to borrow money is also increasing.

Pros and cons of minimum wage

The federal minimum wage hasn’t been raised since 2009. Over the past decade or so, proponents of significantly raising the minimum wage have argued that doing so could reduce reliance on government financial assistance programs and increase consumer spending.
