U.S. consumer prices accelerated sharply in May, with the Bureau of Labor Statistics reporting the all-items CPI increased 0.5% on a seasonally adjusted month-on-month basis as expected, following a 0.6% gain in April.

The annual rate climbed to 4.2%, up from 3.8% in April and 3.3% in March, marking the third consecutive month of strong headline gains and the highest annual reading in over three years.

Real average hourly earnings fell 0.7% over the year through May, extending the squeeze on household purchasing power into a second consecutive month. Core inflation remained comparatively contained at 2.9% annually, but the data gives the Federal Reserve little room to ease policy in the near term.

Key Takeaways

  • Headline CPI: +0.5% month-on-month (seasonally adjusted); +4.2% year-on-year — largest annual gain since April 2023
  • Core CPI (ex-food & energy): +0.2% month-on-month; +2.9% year-on-year (up from 2.8% in April)
  • Energy: +3.9% month-on-month; +23.5% year-on-year — accounted for over 60% of the monthly all-items rise
  • Gasoline: +7.0% month-on-month; +40.5% year-on-year
  • Food: +0.2% month-on-month; +3.1% year-on-year
    • Food at home: +0.1% MoM; food away from home: +0.3% MoM
  • Shelter: +0.3% month-on-month; +3.4% year-on-year
    • Owners’ equivalent rent: +0.3% MoM; primary rent: +0.4% MoM
  • Motor vehicle insurance: -1.7% month-on-month — largest decline since October 2020
  • Airline fares: +2.7% month-on-month; +26.7% year-on-year
  • Medical care: +0.3% month-on-month, driven by dental and hospital services
  • Core goods: -0.1% month-on-month — new vehicle prices fell 0.3%, used cars edged up 0.1%
  • Real average hourly earnings: -0.7% year-on-year

Energy accounted for a large chunk of the increase, as gasoline prices vaulted 7.0% on a seasonally adjusted basis over the month, with fuel oil adding 3.8%, as ongoing US-Iran hostilities in the Middle East kept upward pressure on crude oil through May. The energy index is now running at 23.5% above year-ago levels, its highest since mid-2022.

Stripping out food and energy, however, the picture looks considerably more contained. Core CPI rose just 0.2% on the month after a 0.4% gain in April. The slowdown was partly mechanical: motor vehicle insurance, which had been a persistent source of services stickiness, fell 1.7% in May in its biggest monthly drop since October 2020.

Shelter remained firm but not accelerating. Primary rents rose 0.4% and owners’ equivalent rent posted 0.3%, broadly matching April’s pace rather than re-accelerating.

Airline fares rose a further 2.7%, reflecting the knock-on effect of elevated jet fuel costs while healthcare services gained 0.5%, led by dental and hospital services.

The U.S. dollar initially dipped upon seeing the headline numbers simply come in line with consensus estimates, while measures of core inflation showed slight weakness. However, USD quickly found a bottom within an hour after the release, then staged a steady rebound for the remainder of the session.

By the end of the trading day, the greenback gained roughly 0.30–0.40% against the Australian dollar and New Zealand dollar, approximately 0.23% against sterling, and 0.17% against the euro and Swiss franc. The Canadian dollar was the relative outperformer, finishing near flat against the USD. The Japanese yen lagged slightly on the day.

Equity markets moved lower while US Treasury yields rose, reflecting the repricing of rate cut expectations. The dollar’s intraday recovery from initial weakness is consistent with markets concluding that, while the data doesn’t open the door to a rate hike, it firmly closes the door on near-term rate cuts.
