Inflation is a term that pops up in news headlines, political debates, and everyday conversations about the economy.
It affects everything from the price of your morning coffee to the value of your savings account. But what exactly is inflation, and why does it matter?
Let’s break it down in a way that’s easy to understand, exploring its causes, effects, and why it’s such a hot topic in economics and politics.
Defining Inflation
At its core, inflation is the rate at which the general level of prices for goods and services in an economy increases over time.
When inflation occurs, each unit of currency buys fewer goods and services, meaning your money doesn’t stretch as far as it used to.
The U.S. Bureau of Labor Statistics (BLS) defines inflation as “a process of continuously rising prices or, equivalently, of a continuously falling value of money.”
The most common way to measure inflation is through the Consumer Price Index (CPI), which tracks the average price changes for a basket of goods and services—like food, housing, transportation, and healthcare—that typical households consume.
Another measure, the Producer Price Index (PPI), looks at price changes at the wholesale level, which can signal future consumer price trends.
According to the BLS, the CPI rose by 2.5% in August 2025 compared to the previous year, a moderate increase compared to historical spikes like the 9.1% peak in June 2022.
What Causes Inflation?
Inflation doesn’t just happen out of the blue—it’s driven by a mix of factors.
Economists generally point to three main causes:
- Demand-Pull Inflation: This happens when demand for goods and services outpaces supply. Imagine a hot new gadget everyone wants, but there aren’t enough to go around. Prices rise as people compete to buy it. As Nobel laureate economist Milton Friedman once said, “Inflation is always and everywhere a monetary phenomenon,” often tied to too much money chasing too few goods.
- Cost-Push Inflation: When the costs of producing goods and services go up, businesses pass those costs on to consumers. Think of rising oil prices increasing transportation costs, which then make groceries more expensive. For example, the International Monetary Fund (IMF) noted that supply chain disruptions during the COVID-19 pandemic drove up production costs, contributing to global inflation surges in 2021 and 2022.
- Built-In Inflation: This is like a self-fulfilling prophecy. When workers expect prices to keep rising, they demand higher wages to keep up. Businesses then raise prices to cover those wages, creating a cycle. This is sometimes called the wage-price spiral.
Other factors, like government policies or global events, can also play a role.
For instance, excessive money printing by central banks—like the Federal Reserve increasing the money supply during economic crises—can fuel inflation.
The Federal Reserve’s 2020-2021 stimulus measures, which pumped trillions into the U.S. economy, were linked to the post-pandemic inflation surge, as reported by the Federal Reserve Bank of St. Louis.
Why Inflation Matters
Inflation isn’t just about paying a few extra bucks for groceries—it has far-reaching effects on everyone.
Here’s why it’s a big deal:
- Erodes Purchasing Power: If your income doesn’t rise as fast as inflation, your money buys less. A 3% inflation rate means that $100 today will only be worth about $97 in real terms a year from now.
- Impacts Savings and Investments: Inflation can eat away at savings sitting in low-interest accounts. If your bank pays 1% interest but inflation is 3%, you’re effectively losing value. On the flip side, moderate inflation can encourage investment in assets like stocks or real estate, which may outpace inflation.
- Affects Borrowing and Lending: Inflation influences interest rates. When inflation rises, central banks like the Federal Reserve often raise interest rates to cool the economy, making loans for homes or cars more expensive. In 2022, the Fed raised rates multiple times to tame inflation, as noted in their monetary policy reports.
- Widens Inequality: Inflation can hit lower-income households harder, as they spend a larger share of their income on essentials like food and rent, which often rise faster than other goods. A 2023 study by the Economic Policy Institute found that inflation disproportionately burdened low-wage workers during the post-COVID recovery.
Inflation’s Balancing Act
Despite these negative effects as a result of inflation, not all inflation is bad.
Economists often say a little inflation—around 2% annually, as targeted by the Federal Reserve—is a sign of a healthy economy.
However, Reuters has stated that 3% inflation is the new 2%.
Inflation often times encourages spending and investment, as people are less likely to hoard cash that’s losing value.
The downside is that when inflation gets too high, it can spiral out of control, as seen in historical cases like Germany’s hyperinflation in the 1920s, where prices doubled every few days.
On the flip side, too little inflation—or worse, deflation (falling prices)—can be a problem too.
Deflation might sound great, but it can lead to reduced spending, lower business profits, and higher unemployment, as seen during the Great Depression.
The Federal Reserve’s 2% target aims to strike a balance, keeping the economy humming without letting prices run wild.
How Governments and Central Banks Respond
Central banks and governments have tools to manage inflation, but it’s a tricky dance.
The Federal Reserve, for instance, uses monetary policy to influence inflation.
Raising interest rates makes borrowing more expensive, slowing spending and cooling inflation.
Lowering rates does the opposite, stimulating the economy.
For example, inn 2023, the Fed’s rate hikes helped bring U.S. inflation down from its 2022 peak, though it remained above the 2% target, per BLS data.
Governments can also use fiscal policy, like adjusting taxes or spending, to influence inflation.
For example, reducing government spending can ease demand-pull inflation, while targeted subsidies can soften the blow of cost-push inflation on consumers.
Inflation in Today’s World
As of September 2025, inflation remains a hot topic.
Global events—like ongoing supply chain issues, energy price fluctuations, and geopolitical tensions—continue to influence prices.
The IMF’s 2025 World Economic Outlook noted that while global inflation has cooled from its post-COVID highs, risks like commodity price spikes or labor shortages could reignite it.
For everyday people, inflation feels personal.
It’s the sting of a higher grocery bill or the shock of rising rent.
But understanding what drives it—whether it’s too much demand, rising costs, or policy decisions—helps make sense of the bigger picture.
Wrapping Up
Inflation is more than just a buzzword; it’s a force that shapes how far your dollar goes and how economies function.
While moderate inflation keeps things moving, too much or too little can throw things off balance.
By keeping an eye on measures like the CPI and understanding the push and pull of economic forces, you can better navigate its impact on your wallet and the world around you.
