Headline vs Core Inflation: Methods, Impacts, and Trends

By understanding the differences between these two measures, policymakers can make more informed decisions about monetary policy and better respond to changing economic conditions. One of the key differences between core inflation and headline inflation is the level of volatility in each measure. Since core inflation excludes volatile items like food and energy, it tends to be more stable and less prone to short-term fluctuations. This makes core inflation a useful tool for policymakers to gauge the underlying trend in inflation and make more informed decisions about monetary policy.

Moreover, according to the calculation, the food and petroleum sector’s inflation was 2%. Central banks are inherently non-market-based or even anti-competitive institutions. Although some are nationalized, many central banks are not government agencies, and so are often touted as being politically independent. A central bank is a financial institution given privileged control over the production and distribution of money and credit for a nation or a group of nations.

Forecasts using core inflation typically outperform the Fed’s inflation target at horizons less than a year—an observation that aligns with the results in Breitung and Knüppel’s paper. At longer horizons, it seems prudent to use the Fed’s 2% target as a forecast of inflation. This is logical since policymakers actively conduct monetary policy so that future inflation will reach its target.

It is common for products to improve in quality while the price remains the same. It is especially applicable to technology products like cell phones and computers. This method removes the products and services with the largest volatility while calculating. Purchasing headline inflation vs core inflation power is the value of a currency expressed in terms of the number of goods or services that one unit of money can buy. Purchasing power is important because, all else being equal, inflation decreases the number of goods or services you would be able to purchase.

Core Inflation Revisited: Forecast Accuracy across Horizons

The urban core inflation rate as of May 30, 2024, based on the consumer price index excluding food and energy for U.S. cities. Headline inflation includes all items in the Consumer Price Index (CPI), making it susceptible to volatile price changes in food and energy sectors. Core inflation, on the other hand, excludes these categories to provide a more stable measure of long-term trends. Inflation is a critical economic indicator that affects everything from consumer purchasing power to monetary policy decisions. Understanding the nuances between different types of inflation, such as headline and core inflation, is essential for grasping their broader implications on the economy. Our results suggest that there are clear limitations to how far into the future we can forecast inflation.

1. There are many measures of aggregate price changes that differ in what prices they cover and how much weight each price category has.
2. The Federal Open Market Committee has targeted inflation in the PCEPI since the 1990s, however, and made that index its official inflation target in January 2012.
3. The choice between using core inflation or headline inflation as a policy tool depends on the specific goals of policymakers and the context of the economic environment.
4. Though GDP is typically calculated on an annual basis, it is sometimes calculated on a quarterly basis as well.
5. There are a few more, mostly minor differences, related to items such as how seasonal adjustments are handled.

What Is Purchasing Power?

For instance, housing costs typically receive a higher weight than entertainment expenses because they constitute a larger portion of household spending. These weights are periodically updated to reflect changes in consumer behavior, ensuring that the CPI remains relevant and accurate. This weighting process is essential for capturing the true impact of price changes on consumers’ purchasing power. Examining the time series of each of these components’ inflations more closely, we find that most had consistent negative price growth over the entire period.

Core inflation is often described as a measure of “underlying” or “trend” inflation. The New York Fed’s Applied Macroeconomics and Econometrics Center constructs a measure of core-trend inflation with sophisticated statistical techniques that seek to model the persistent component of inflation. Understanding the distinction between headline and core inflation is fundamental for interpreting economic data accurately. Headline inflation encompasses the total change in the cost of all goods and services within the Consumer Price Index (CPI). This broad measure captures the immediate impact of price fluctuations, including those in volatile sectors like food and energy. Consequently, headline inflation can exhibit significant short-term variability, reflecting sudden spikes or drops in these categories.

It differs from core inflation, which is CPI adjusted to exclude food and energy prices, which are volatile. Headline inflation is a useful measure of how the cost of living might fluctuate on a monthly or yearly basis. By computing inflation in this way, median PCE inflation is not influenced by the magnitude of any price change that appears in one of the tails of the distribution. Price stability is a fundamental mission of monetary policy, because inflation—a rise in the general price level—that is greater than fairly low levels distorts economic decisions and makes people worse off.
