No one likes paying more for something than they did last month or last year. Still, a little inflation is arguably essential for a healthy economy. The time to worry is when inflation goes âhyperââor when it reverses and prices fall.
When inflation is relatively stable over long periods, you donât need to fret much about how rising or falling prices might affect your plans to make a large purchase or borrow money. You can also hold onto money for years without inflation eroding most of its value. This is sometimes called a âGoldilocksâ scenario, where inflation isnât too hot or too cold. Although economists donât agree on what constitutes not-too-hot/not-too-cold inflation, the U.S. Federal Reserve (Fed) targets a 2% inflation rate that may represent a âjust rightâ level.
When inflation sizzles, the value of savings erodes, borrowing costs tend to rise, and many people canât afford essential items. Gross domestic product (GDP) often begins to weaken.
When prices deflate, people hold onto their money as they wait for prices to fall even more. Inventories build, wages deflate, people lose their jobs, and, once again, GDP sags. One key task of the Fed is maintaining price stability in order to keep Goldilocks inflation in place. But no economy is immune from outbreaks of high and low inflation that can upend growth and jump-start the misery meter.
Prices tend to rise when:
Inflation can also occur when governments inject money into the economy. This can reduce the value of the currency relative to the things it will buy, causing producers to demand more cash for the things they make and sell.
Deflation, the opposite of inflation, is typically a drag on an economy. A deflationary spiral is when:
To better understand inflation versus deflation and their effect on the economy, it helps to study how economies have reacted in both cases. Itâs not pretty.
It may sound counterintuitive, but falling prices can actually be associated with more misery than rising ones. The worst economic crisis in U.S. history, the Great Depression, was characterized by deflation. More recently, the COVID-19 pandemic shut down the global economy in 2020 and triggered a deep (but ultimately short) global recession. What memory surfaces (besides being cooped up playing board games with your family)?
Maybe itâs the rock-bottom price of gasoline. At one point in 2020, oilâs value actually fell below zero as producers became willing to pay to have the stuff taken away. Almost no one was traveling, and all that crude oil suddenly had no present-day value. Prices at gas stations across the country fell below $2 a gallon. But that didnât benefit many people, because most werenât going anywhere, particularly during the pandemic-related shutdowns.
Deflation was also widespread during the Great Depression. This severe downturn had many possible causes, but one stands out in terms of deflation: Consumers lost their desire to spend. This began a deflationary spiral where companies saw inventories rise and had to lay off workers, fueling more economic weakness that reduced spending even more. Anyone wanting to sell something had no choice but to lower prices.
As prices fell, economic growth slowed further, in part because companies lost their incentive to make products they knew couldnât be sold at a profit. That forced more layoffs, raising unemployment and pressing GDP further into the red.

Between the peak and the trough of the downturn from late 1929 to early 1933, industrial production in the U.S. declined 47% and real GDP fell 30%. The U.S. Consumer Price Index (CPI), which measures price growth, fell 33% during that period. And unemployment? Around 25%. One in four workers couldnât find a job. Thatâs the true and sad impact of deflation.
The opposite of deflation is hyperinflation. One of the best-known examples of hyperinflation happened in Germany after World War I. The government printed so much money trying to pay off war-related debt that the value of its currency collapsed. By November 1923, one U.S. dollar was equivalent to 1,000,0000,000,000 (one trillion) marks, compared with four marks before the war. A wheelbarrow full of money couldnât buy a newspaper. Many people burned money in their fireplaces to keep warm.
That kind of hyperinflation didnât just mean paying a fortune for bread. It destroyed peopleâs savings. Imagine a German worker whoâd spent their entire life saving a million marks ($250,000 in prewar value). Suddenly, that entire million couldnât even buy a newspaper.
Although that extent of hyperinflation is rare, even a bit of high inflationâlike what the U.S. and many other countries experienced in the early 2020sâcan erode savings and hurt quality of life.
After the COVID-19 pandemic, inflation screamed to 40-year highs. Consider some reasons:
Making matters worse, crude oil spiked in 2022 after Russia invaded Ukraine and Western governments limited Russian energy imports. This gave companies the unappetizing choice of swallowing higher raw materials costs (hurting their operating margins and thus profits) or passing along their heftier costs to consumers. The first option hurts investors, the second hurts consumers. Both hurt the economy.
Prices for gasoline, cars, and groceries rose more quickly than in 40 years, and people demanded higher wages to pay for the increased cost of goods. Companies did their best, but many werenât able to give raises that kept up with inflation. A 5% raise may sound great, but not if prices recently skyrocketed 9%. When prices rise faster than wages, consumers lose. They might spend less, slowing economic growth. Indeed, U.S. GDP growth fell in the first half of 2022 after rising dramatically in 2021.
Some economists began to fear a âwage-price spiral,â like the one in 1979â81. Back then, people got used to double-digit price gains, ramped up their inflationary expectations for the future, and demanded double-digit wage hikes to keep up with this perceived future inflation. Companies tried to accommodate them, but jacked up prices to afford paying the higher salaries. And so on and so onâa cycle that helped fuel the stagflation of the late 1970s and early 1980s.
The cycle only stopped when the Fed stepped in and increased borrowing costs to record highs. This cooled inflation, but subjected the economy to two deep recessions in the early â80s that fueled double-digit unemployment.

If one thing stands out about both inflation and deflation, itâs lack of stability. People donât know how much things will cost in the future, but base their spending decisions on expectations of what goods might cost. Companies also donât know what to expect, and central banks have to react quickly by raising or lowering borrowing costs. Sometimes central banks resort to âquantitative easing,â in which they buy bonds or other assets to stimulate growth (and fend off possible deflation).
In a Goldilocks economy where inflation is relatively stable and predictable year after year, consumers, companies, and the government can make long-term spending and investment decisions with less uncertainty. In general, markets donât like uncertainty, so stocks and the overall economy tend to do better when Goldilocks finds the inflation rate thatâs âjust right.âHyperinflation in the Weimar Republic | britannica.com
