Gas, electricity, food, and medical care all pushed prices higher in May, sending annual inflation to 4.2 percent, a level not seen since April 2023. The Bureau of Labor Statistics reported the figures Wednesday, showing that the consumer price index rose a seasonally adjusted 0.5 percent for the month. Both numbers matched Wall Street forecasts, according to CNBC.
The monthly gain was 0.1 percentage point below April's reading, but the annual rate still crossed above 4 percent for the first time in three years. The previous reading, from April, was 3.8 percent.
Much of the jump traced back to energy. Oil and related costs surged 3.9 percent in a single month, putting the 12-month gain in energy prices at 23.5 percent. The United States has remained in active conflict with Iran, and markets were shaken again Wednesday when President Donald Trump warned that Iran will "pay the price" for not accepting a peace deal. Concern is growing that the oil shock could spread further into energy-sensitive parts of the economy.
"Americans are getting squeezed financially by inflation that's back at a 3-year high," said Heather Long, chief economist at Navy Federal Credit Union. "The frustration for many Americans is that so many of the basics are up in price right now -- gas, food, electricity, and medical care are all clear pain points that are above 3% inflation. Ending the war in Iran will help to moderate inflation, but the worst is likely still to come for rising food prices."
The so-called core CPI, which strips out volatile food and energy prices, told a softer story. That measure rose only 0.2 percent for the month and 2.9 percent over the past year. The monthly gain came in below the 0.3 percent estimate and well under April's 0.4 percent increase. Core commodity prices actually fell 0.1 percent in May, a sign that tariff-related pressures on goods have not yet spread widely through the economy.
Food costs rose just 0.2 percent for the month. Shelter, which carries more than one-third of the total CPI weighting, rose 0.3 percent in May, half the gain recorded in April. On an annual basis, shelter costs were up 3.4 percent.
Not all economists read the report the same way. Chris Rupkey, chief economist at Fwdbonds, argued that the broader alarm may be overstated. "Washington economic officials are going to redouble their efforts to tell Americans there isn't a cost-of-living crisis," Rupkey said. "The sky isn't falling after all and the inflation risks for core consumer goods are in retreat for now."
The report lands at a difficult moment for the Federal Reserve. Officials on the rate-setting Federal Open Market Committee are scheduled to release their next interest rate decision on June 17. Markets largely expect the committee to hold rates steady, but investors will be watching the statement closely for any signal about how seriously the Fed views the energy-driven inflation surge. Stock market futures held in negative territory after the report's release, though they were off their earlier lows. Treasury yields were roughly flat.
The combination of a Middle East conflict, elevated energy prices, and a Fed decision less than one week away gives the May inflation report unusual weight. Whether the core softness convinces policymakers to stay patient or the headline number pushes them toward a more cautious tone will become clearer when the Fed speaks on June 17.
