These days, you canât tune into TV or social media without hearing about inflation. But what is inflation, why does it happen, how is it measured, and are rising prices good or bad? Alarm bells ring if prices rise too quickly, but the oppositeâdeflation, or falling pricesâis arguably worse. Economists and policy makers tend to like the Goldilocks levelâone thatâs not too hot or cold.
Of course, it doesnât feel pleasant when your morning cappuccino goes up 25 cents or the landlord hikes your rent. But mild inflation can signal a healthy economy, reflecting both firm demand and growing wealth. You donât generally see much inflation during recessions.
Paying more for your coffee or rent is one inflation definition. But inflation also refers to overall increases in prices and the cost of living. Governments measure the inflation rate by putting together a basket of common goods and services and calculating how much theyâd cost each month.
Producer inflation measures wholesale prices, meaning prices paid by businesses that purchase large volumes of product. Another type is wage inflation, which may sound good for your paycheck, but can spell economic trouble if it gets out of hand.
Inflation is a natural and healthy part of a growing economy, provided it stays under control and workersâ salaries donât lag behind the general rise in prices. Prices rise as populations grow, economies get richer, demand increases, and commodities get scarcer and more expensive. Companies hike prices to meet rising demand, or to pay higher wages and buy more expensive raw materials.
When governments inject money into the economy, it can reduce the value of the currency relative to what it can buy, prompting producers to demand more cash for the goods they make and sell.
Another common cause of inflation is a shortage of raw materials, which can be caused by heavy demand (lumber prices exploded after the start of the global pandemic) or supply problems (oil hit near-record highs in 2022 when Russia invaded Ukraine and multiple nations cut off most Russian oil imports).
Stagflation is a portmanteau of the words stagnation and inflation. Itâs when the economy slows down, but prices didnât get the memo.

Oil often gets blamed for inflationary bumps because, like your coffee, everything runs on it. You need oil to go places; companies need it to make and ship their products. When pricey oil raises shipping costs for businesses, that often gets passed along to customers in the form of higher price tags for all sorts of goods. Thatâs inflation causing inflation in a vicious cycle.
The government tracks U.S. inflation and provides monthly updates through the Consumer Price Index (CPI) and Producer Price Index (PPI) reports. The first one monitors prices paid by consumers, the second tracks wholesale prices.
CPI and PPI are measured in two ways:
Sometimes PPI and CPI rise at different rates. When producer prices rise, companies donât always immediately pass along their higher costs to consumers, fearing loss of demand.
In a strong economy, however, many companies eventually do hike prices if they believe consumers can afford to pay more. Companies that pay higher wholesale costs and donât raise customer prices risk a decline in profit margins. Thatâs why a rise in PPI is often followed by a rise in CPI as companies accept the inevitable and ask their customers to help foot the bill for pricier shipping or raw materials.
For about a decade leading up to 2020, the Federal Reserve maintained a 2% target rate of inflation. Why not zero? Because inflation can drive economic growth in several ways:
Just the thought of inflation can get consumers to buy. Say youâve spent several years saving $5,000 for a down payment on a new car, and you know car prices have been rising 5% each year. Rather than wait and risk paying more, you decide to buy the car now.
Say youâve been paying $5 for a 20-ounce loaf of bread. One day, that same loaf costs $5.50âa 10% increase. Thatâs inflation.
Now imagine the manufacturer trims the loaf to 18 ouncesâa 10% reduction in sizeâbut keeps the price at $5. Thatâs shrinkflation.
No matter how you slice itâor how you price itâyouâre getting 10% less for your money. Learn more about shrinkflation.
If prices were flat or falling, you might hold off on making a purchase. But the prospect of rising prices can motivate consumers to spend sooner, which helps keep money circulating. That spending, in turn, supports businesses and wages throughout the economy.
Thatâs why economists often say that one personâs expenditure is anotherâs income.
Now envision this happening every day across the country among millions of consumers and businesses. Consumer spending accounts for about 70% of U.S. gross domestic product (GDP), and can be a major force to stimulate economic growth.
To help fuel or cool inflation, governments may use fiscal policy tools such as increased spending, tax cuts, or stimulus checks. These actions inject large sums of money into the economy during slowdowns, encouraging consumers to spend and companies to invest.
When the economy slows, the central bank can reduce the Fed funds rate and/or buy fixed-income securities (Treasury bonds and mortgage-backed securities, for example) to make borrowing easier, inspiring businesses to invest and consumers to buy cars and homes.
If inflation runs hot, it can raise rates and/or decrease the size of its balance sheet by selling securities. Higher rates make mortgages and car loans more expensive, reducing demand and slowing the flow of money through the economy. Over time, that can ease inflation.
Both now and historically, the U.S. inflation rate has been a burning political and economic issue. In the 1970s, Washington even launched an effort called Whip Inflation Now (WIN), with its own campaign buttons. The Fed eventually helped whip that historic inflation by jacking up interest rates to all-time highs above 15%, but not without tons of consumer pain through two back-to-back recessions in the early 1980s.
Fear of Fed tightening tends to hurt stocks, and falling stock prices can make investors and companies nervous and less likely to spend, slowing the economy. Thatâs another reason why a little inflation is good, but a lot hurts. Deflation also hurts, as seen during the Great Depression. Whatâs the Goldilocks level? Economists differ, but that 2% rate continues to be the Fedâs target.
