US consumer prices accelerated to a 3.7pc annual rate in August, led by a surge in monthly gasoline prices, even as slowing core inflation is likely to keep Federal Reserve policymakers on track to hold their key policy rate unchanged at next week's meeting.
Last month's gain in the consumer price index (CPI), which tracks prices of goods and services, was more than most forecasts and compared with a 3.2pc annual rate in July, according to the Bureau of Labor Statistics.
Core inflation, which strips out volatile food and energy prices, slowed to a 4.3pc annual rate — the lowest since September 2021 — from a 4.7pc pace in July. But on a monthly basis core inflation rose by 0.3pc, largely on shelter, following a monthly gain of 0.2pc in July.
"We expect the Fed to remain on hold, but to signal willingness to hike again depending on the data," said Ian Shepherdson, chief economist at Pantheon Macroeconomics.
Fed policy makers meet on 20 September to determine the course of monetary policy. The CME's FedWatch tool gives 97pc odds today that the Fed will hold its target rate unchanged after hiking 11 times since March 2022, up from 93pc odds yesterday.
Energy index leads the way up
Inflation has been easing since peaking at an annual 9.1pc rate in June 2022, but recent gains in oil and other energy prices are pushing up overall prices once again.
The energy index decreased by an annual 3.6pc rate in August following a 12.5pc decline in the 12 months through July. The gasoline index fell by an annual 3.3pc after a 19.9pc annual decline in the 12 months through July. Still, the gasoline index rose by 10.6pc for the month of August, accounting for half of the overall headline monthly gain in the CPI, after a monthly gain of 0.2pc in July.
Headline CPI posted a 0.6pc monthly gain in August, more than forecasts, following 0.2pc monthly gains in the prior two months. Along with the monthly pickup in energy, shelter also contributed to the monthly uptick, the BLS said.
The food index rose at an annual 4.3pc in August after a 4.9pc gain in July. The shelter index rose by 7.3pc after an annual gain of 7.7pc in the 12 months through July.
Transportation services rose by an annual 10.3pc in August after a 9pc gain in July.
