When Federal Reserve officials discuss inflation, they often focus on core inflation rather than overall inflation. Core inflation excludes food and energy prices because those categories can swing dramatically due to events such as geopolitical conflicts, weather or supply disruptions. By filtering out those short-term spikes, policymakers get a clearer picture of whether inflation is spreading across the broader economy.
In a speech this week, Federal Reserve Governor Christopher Waller said rising core inflation—not just higher gasoline prices—is what concerns him most. If core inflation remains elevated for several months, the Federal Reserve could consider raising interest rates to slow spending and bring inflation closer to its long-term 2% target. Because Fed policy influences borrowing costs throughout the economy, changes in core inflation can ultimately affect everything from mortgage rates and car loans to credit cards and savings yields.
Core inflation measures price changes excluding food and energy because those costs tend to fluctuate sharply from month to month. Federal Reserve policymakers watch core inflation to gauge whether price increases are becoming widespread throughout the economy. Persistent increases in core inflation can influence interest-rate decisions that affect mortgages, auto loans, credit cards and savings accounts.
The distinction between core and headline inflation is crucial for understanding the Fed's policy trajectory. While headline inflation may spike due to temporary factors like a hurricane driving up gasoline prices, core inflation provides a more stable signal of underlying price trends. If core inflation remains elevated for several months, it suggests that price pressures are becoming embedded in the economy, prompting the Fed to act.
Higher interest rates tend to slow economic activity by making borrowing more expensive, which can reduce demand for goods and services and help bring inflation down. However, this also means higher costs for consumers and businesses, impacting everything from home purchases to corporate expansion plans. The Fed's focus on core inflation underscores its commitment to achieving price stability, even if it means accepting some short-term economic pain.
As the Fed continues to monitor core inflation, markets will be watching for any signs that could trigger a policy shift. For investors and consumers alike, understanding core inflation is key to anticipating changes in the financial landscape.
