US Inflation Accelerates in August on Higher Gas Prices, Bolstering Fed Rate Hike Bets

U.S. consumer prices accelerated in August, propelled by a rebound in gasoline costs, reinforcing market expectations that the Federal Reserve will implement another interest rate hike at its policy meeting next week.

August Inflation Data

The Consumer Price Index (CPI) increased by 0.4% last month, a notable pickup from July's 0.1% rise, the U.S. Bureau of Labor Statistics reported on Friday. The annual inflation rate held steady at 3.4%. Both figures were in line with market expectations.

Excluding volatile food and energy components, the core CPI rose 0.3% month-over-month, slightly ahead of the 0.2% forecast and the prior month's reading. On an annual basis, core inflation eased to 2.4% from 2.5% in July, meeting projections.

Federal Reserve Outlook

The latest inflation report, combined with recent data showing a strong labor market and rising producer prices, strengthens the case for the central bank to continue its monetary tightening campaign. The data provides a key piece of information for policymakers ahead of their upcoming meeting on September 15-16.

Financial markets have increasingly positioned for another rate increase. According to the CME FedWatch Tool, traders before the report had priced in an approximately 70% probability of a 25 basis point hike. The Fed's current benchmark overnight interest rate is in a target range of 3.50% to 3.75%.

Broader Economic Pressures

Persistent price pressures remain a key concern for the economy and investors. Crude oil prices have recently climbed back above $100 per barrel, with diesel prices hitting record highs, suggesting that energy-related inflation could continue to be a factor.

The economic backdrop is further complicated by political factors. President Donald Trump has publicly pressured the Federal Reserve to cut interest rates. Some economists have suggested the central bank may proceed with a rate hike next week in part to assert its independence from political influence.
