core inflation
The change in prices of goods and services excluding food and energy, providing a less volatile measure of underlying inflationary trends.
Example
“While headline inflation was 7%, core inflation of 5% excluded the volatile food and energy components driving much of the increase.”
Memory Tip
CORE inflation = headline CPI minus food and energy. More stable signal of underlying price pressure.
Why It Matters
Core inflation helps you understand the true underlying cost pressures in the economy beyond temporary price swings. This matters for your personal finances because it influences central bank decisions about interest rates, which directly affect mortgage rates, savings account returns, and borrowing costs for loans and credit cards.
Common Misconception
Many people mistakenly believe core inflation is more accurate than overall inflation because it excludes food and energy. However, food and energy are real expenses that come out of your household budget, so ignoring them can make core inflation seem lower than what you actually experience when paying for groceries and gas.
In Practice
In 2023, overall inflation might have been 4 percent when measured with food and energy included, but core inflation could have been 5 percent if food and energy prices dropped significantly. The Federal Reserve might focus on that 5 percent core rate when deciding to raise interest rates, even though you would have felt relief at the gas pump and grocery store from those lower food and energy costs.
Etymology
CORE (central, essential) INFLATION. The CORE (underlying) rate of INFLATION without volatile components.
