(Reuters) -U.S. consumer prices rose marginally in August, but underlying inflation showed some stickiness, which could discourage the Federal Reserve from delivering a half-point interest rate cut next week.

The consumer price index increased 0.2% last month after climbing 0.2% in July, the Labor Department said on Wednesday. In the 12 months through August, the CPI advanced 2.5%. That was the smallest year-on-year rise since February 2021 and followed a 2.9% increase in July.

Economists polled by Reuters had forecast the CPI gaining 0.2% and rising 2.6% year-on-year. Though inflation remains above the U.S. central bank's 2% target, it has slowed considerably.
