How the Consumer-Price Index Measures Inflation | WSJ

Summary

The video explains how the U.S. Consumer Price Index (CPI) measures inflation and how policymakers use it. In 2022, CPI rose at its fastest pace in more than four decades. It is one of the most closely watched inflation measures and informs decisions such as adjustments to tax brackets, Social Security benefits, and food stamps. The Federal Reserve also monitors it.

How CPI Is Calculated

• The Bureau of Labor Statistics (BLS) tracks prices for a basket of goods and services that represents average household spending.
• Categories receive different weights based on surveys of what consumers buy. Food, transportation, and housing are among the major categories; housing is described as the largest out-of-pocket expense.
• More than 450 BLS workers track prices for as many as 100,000 goods and services and 8,000 housing units each month.
• CPI reflects spending by urban consumers who pay directly out of pocket. It excludes certain non-direct payments, including some services provided by nonprofits, Medicare and Medicaid, and employer-sponsored health plans.
• CPI’s basket is updated every two years, so it may not quickly reflect changes in consumer behavior.

CPI, PCE, and Federal Reserve Policy

• The Fed also considers the Personal Consumption Expenditures (PCE) Price Index, whose basket changes monthly with consumer trends. Differences in methodology can lead CPI and PCE to show somewhat different inflation readings.
• PCE prices rose 6.3% over the 12 months through April; the year is not specified in the subtitles.
• The Fed considers multiple indexes and pays close attention to CPI’s month-to-month movement as a gauge of whether inflation has momentum.
• The Fed’s stated goals are maximum employment and stable prices.

Risks and Implications

• Inflation varies by household. For example, people who drive to work may feel rising gasoline prices more than subway commuters.
• Persistent inflation in essentials such as housing and food can become embedded in the economy. Rising household bills may lead workers to seek higher wages, while businesses may raise prices if customers continue paying them—potentially sustaining inflation.
• Changes in individual CPI categories can help show whether inflation is broadening.
