U.S. consumer prices rose 3.4% in August from a year ago, matching July’s rate and Wall Street forecasts. The steady inflation reading, paired with a stronger-than-expected jobs report, has pushed traders’ expectations for a Federal Reserve interest-rate hike next week to nearly 90%.
The consumer price index increased 0.4% on a monthly basis, marking the largest monthly gain in three months, according to data tracked by CoinPedia. Gasoline prices jumped 3.9%, driving more than a third of that monthly advance. Core inflation, which strips out volatile food and energy items, eased slightly to 2.4% annually from 2.5% in July, reaching its lowest level since March 2021.
Energy Costs and Diesel Prices Drive Monthly Acceleration
Energy expenses fueled the monthly acceleration, rebounding after a softer prior month. Pump prices climbed sharply, while broader energy commodities experienced dramatic swings. Brent crude futures surged overnight toward $110 a barrel before easing back to roughly $104, reflecting lingering geopolitical tensions and Middle East conflicts. Meanwhile, the cost of diesel reached $6 a gallon, according to AAA.
Food inflation held near a modest 0.2% monthly increase, while core categories showed mixed movement. Airfares climbed about 3% for the month, and lodging costs rebounded following two weak months. Conversely, medical-care inflation showed signs of moderation, shelter inflation began cooling, and used-car price pressures slowed.
Fed Rate Hike Probabilities Surge Ahead of September Meeting
With inflation persisting above the central bank’s target and a robust August jobs report showing nonfarm payrolls grew by 162,000, market participants quickly recalibrated their expectations for monetary policy. The Federal Reserve meets on September 15–16 to decide its next move on interest rates.
Traders placed the probability of a rate hike at nearly 90%, up sharply from earlier in the month when expectations sat near 58% on the CME FedWatch tool. Analysts noted that the latest price figures reinforced a growing belief that underlying pressures remain too robust for policymakers to pause tightening.
Market analysts indicated that a core CPI reading of 0.2% would have kept the Federal Reserve’s decision balanced.
Despite the prevailing anxiety surrounding potential monetary tightening, some market strategists urged caution against overreacting to incoming data points. CFRA Research Chief Investment Strategist Sam Stovall described the current environment as a tug of war between those who are worried that the Fed will be raising rates and those who think that the Fed will remain on the sidelines

Treasury Yields and Market Reactions to the Inflation Report
Bond markets reacted immediately to the inflation release. The benchmark 10-year Treasury yield slipped to 4.92% from approximately 4.94%, while the 2-year Treasury yield—which is particularly sensitive to central bank policy shifts—rose about 3 basis points to approximately 4.37%, according to Vanguard senior fixed-income client portfolio manager Joyce Huang.
Longer-term yields remain a central concern for equity investors. Ameriprise Chief Market Strategist Anthony Saglimbene warned that rising sovereign debt yields could create sustained headwinds.
“Yields are becoming a larger deal for the market. Markets see volatility increase when longer-term rates are moving higher, and I think that is going to be an underlying issue for the market for the rest of this year.”

Stock indexes opened higher following the report as investors welcomed proactive steps to cool price growth, with the Dow Jones Industrial Average rising more than 500 points, or about 1%, in morning trading.
