The U.S. Bureau of Labor Statistics reported that the Consumer Price Index (CPI) for All Urban Consumers fell by 0.1% in June 2024 on a seasonally adjusted basis, following a flat reading in May. This monthly decline marked the first time the index has dropped since May 2020. Over the 12 months ending in June, the all-items index rose 3.0%, a deceleration from the 3.3% increase recorded for the period ending in May.
Factors Driving the June Price Shift
The decline in the monthly CPI was largely driven by a cooling in energy prices and a modest easing in core inflation. According to the Bureau of Labor Statistics (BLS), the energy index fell 2.0% in June, with gasoline prices declining by 3.8% over the month.
While energy costs provided downward pressure, the index for shelter—a significant component of the overall CPI—continued to rise, increasing by 0.2% in June. This was a smaller increase than the 0.4% rise seen in May. The index for food, meanwhile, increased by 0.2% in June, matching the growth rate from the previous month.
Core Inflation and Economic Context
Economists often look at the "core" CPI, which excludes volatile food and energy prices, to get a clearer picture of long-term inflation trends. In June, the core CPI rose 0.1% on a seasonally adjusted basis, the smallest monthly increase since January 2021. Over the last 12 months, the core index rose 3.3%, representing the smallest 12-month increase since April 2021.
This data is closely monitored by the Federal Reserve as it evaluates the trajectory of interest rates. The central bank has maintained a target inflation rate of 2.0% and has kept interest rates at a 23-year high to curb price growth. The June report suggests that inflationary pressures are continuing to moderate, though they remain above the Fed’s long-term target.
Comparison of Recent CPI Trends

| Period | All Items (12-month change) | Core Index (12-month change) |
|---|---|---|
| April 2024 | 3.4% | 3.6% |
| May 2024 | 3.3% | 3.4% |

Frequently Asked Questions
What does the CPI measure?
The Consumer Price Index measures the average change over time in the prices paid by urban consumers for a market basket of consumer goods and services, including food, energy, housing, and medical care.
Why did the index drop in June?
The primary driver was a decrease in energy costs, specifically gasoline, which offset ongoing price increases in other categories like shelter and food.
What is the difference between headline and core inflation?
Headline inflation includes all items in the CPI basket, including volatile categories like food and energy. Core inflation strips these out to provide a more stable view of underlying price trends.
What is the current 12-month inflation rate?
As of June 2024, the all-items index rose 3.0% over the preceding 12 months, according to the BLS.
