Scott Olson | Getty Images Prices for a wide swath of goods and services continued to climb in August, according to a report Friday that raises the specter of a Federal Reserve interest rate hike next week. The consumer price index rose a seasonally adjusted 0.4% for the month, putting the 12-month increase at 3.4%, the Bureau of Labor Statistics reported Friday. Both readings were in line with the Dow Jones consensus. However, stripping out volatile food and energy prices, core CPI posted a 0.3% monthly gain, or 0.1 percentage point higher than forecast. The core annual rate came in at 2.4%, in line with the estimate. The report is the final major inflation indicator the Fed will see before it holds its policy meeting next week, concluding Wednesday with a vote on its key interest rate. Traders responded to the numbers by ramping up bets that the Federal Open Market Committee will increase its benchmark interest rate by a quarter percentage point. Odds for a hike jumped to about 90%, according to the CME Group's FedWatch tracker of fed funds futures prices. Energy propelled the headline number higher, as gasoline prices jumped 3.9%, accounting for more than one-third of the index's gain. The energy index broadly rose 2.1% amid pressure from escalating tensions in the Middle East and was up 16.3% from a year ago. Food prices edged 0.1% higher as food at home costs held flat. The food index accelerated 2.7% annually. Another significant factor was a 0.3% climb in shelter costs, which had moderated over the prior two months. Transportation services saw a 0.5% increase. Used cars and trucks rose 0.4% and new vehicle prices were up 0.3%, part of what appeared to be broad-based gains for the index. Heading into the CPI release, markets already were pricing in a nearly 70% probability that the central bank would vote to increase its benchmark interest rate by a quarter percentage point. However, there have been differing views on which way the rate-setting Federal Open Market Committee will tilt, with some speculating that the difference could come down to hundredths of a percentage point in the CPI reading. Chairman Kevin Warsh has expressed a commitment to getting inflation back down to the Fed's 2% target and said recently that if the numbers don't improve, "we have work to do." His comments were widely interpreted as advocating a rate hike, though several key officials over the past few weeks have counseled a more patient approach. "Chair Warsh and others signaled that interest rates can remain on hold only if disinflation continues and today's August report did not deliver that," said Kathy Bostjancic, chief economist at Nationwide. "Further, the renewed march higher in oil, gasoline and diesel prices add to concerns that higher energy prices could spill over to other goods and services and inflation expectations." Nationwide now expects a quarter-point hike next week. The Fed funds rate, a benchmark for multiple consumer loans, is currently pegged in a range of 3.5%-3.75%, where it has been for all of 2026.
