June 12, 2026—The latest Consumer Price Index (CPI) report from the U.S. Bureau of Labor Statistics (BLS) shows inflation accelerating in May 2026, driven largely by rising energy prices. The data offers a clear snapshot of where consumers are feeling the most pressure—and where price growth is beginning to ease.
Inflation Trends Up
According to the BLS, the CPI for All Urban Consumers (CPI-U) increased 0.5 percent in May on a seasonally adjusted basis, following a 0.6 percent rise in April. On an annual basis, inflation reached 4.2 percent over the 12 months ending in May. This marks a noticeable uptick from April’s 3.8 percent annual rate, signaling that inflationary pressures remain persistent in the broader economy.
Energy Drives the Increase
Energy costs were the primary factor behind the most recent increase. The BLS reports that the energy index rose 3.9 percent during the month and has surged 23.5 percent over the past year. Gasoline prices played a major role, increasing 7.0 percent in May alone and rising more than 40 percent over the past year. Overall, energy accounted for more than 60 percent of the total monthly increase in consumer prices, underscoring its outsized impact on household budgets.
Food Prices Continue to Climb, Though More Slowly
Food prices continued to rise, but at a slower pace compared to energy costs. Overall food prices increased 0.2 percent in May, with grocery prices edging up just 0.1 percent while dining out rose 0.3 percent.
On an annual basis, food prices are up 3.1 percent, with notable increases in categories such as fruits and vegetables as well as nonalcoholic beverages, according to BLS data.
Core Inflation Remains Relatively Stable
Core inflation, which excludes the more volatile food and energy categories, rose 0.2 percent in May and 2.9 percent over the past year. Monthly increases were driven by higher prices in communication services, airline fares, medical care, personal care, and recreation.
At the same time, some categories saw declines, including motor vehicle insurance, which fell 1.7 percent, along with decreases in new vehicle prices and household furnishings.
This mixed picture suggests that while underlying inflation is moderating in some areas, it remains uneven across sectors. The CPI report discusses the nuances of the data in detail.
Housing and Services Continue to Climb
Shelter costs, which includes costs for both rental and owned properties, and is a major component of inflation, increased 0.3 percent in May and are up 3.4 percent over the past year. The BLS notes that both rent and owners’ equivalent rent contributed to this rise, reflecting ongoing pressure in housing markets nationwide.
Services overall, which include food, vehicles, apparel, medical care commodities and services, shelter, and transportation, excluding energy, also continue to trend upward, increasing 3.4 percent year-over-year.
Looking Ahead for Members
The May report highlights that credit unions should be prepared for a mixed inflation environment as stabilizing core prices are offset by rising energy costs. This may impact member spending and borrowing behavior, making it important to monitor trends, adjust pricing strategies, and proactively support members with budgeting guidance. Members, in turn, should stay mindful of fluctuating expenses, especially energy costs—and prioritize flexibility in their financial plans.
