Markets price in a 90% chance of a September Fed rate hike after August inflation data showed core prices accelerating to 0.3% month-over-month.
The Federal Reserve is now widely expected to raise interest rates at its September 16 meeting after a hotter-than-anticipated inflation report signaled that price pressures are broadening across the U.S. economy. Market-implied probability for a 0.25 percentage point hike has surged to nearly 90%, up from 70% just one day prior, as investors recalibrate for a more aggressive central bank policy [1].

|---|---|
| August CPI (Annual) | 3.4% |
| Core CPI (Monthly) | 0.3% |
| Rate Hike Probability | ~90% |
| 2-Year Treasury Yield | Highest close since July 2024 |
The Consumer Price Index rose at an annual rate of 3.4% in August, matching the previous month’s reading but exceeding the 3.3% forecast by economists [1]. While headline inflation was driven significantly by a 27.4% year-over-year jump in gasoline prices, the core CPI—which strips out volatile food and energy costs—accelerated to a 0.3% monthly increase, up from 0.2% in July [1]. This uptick suggests that higher fuel costs are beginning to ripple through the broader economy, complicating the Federal Reserve's path toward its 2% inflation target [1].
The shift in market sentiment has been swift. Following the data release, the 2-year Treasury yield climbed to its highest close since July 2024, reflecting investor expectations for higher borrowing costs [3]. Despite the hawkish outlook, U.S. equities saw broad gains on Friday, with the S&P 500 rising 0.9% and the Nasdaq and Dow Jones Industrial Average each gaining approximately 1% as oil prices pulled back from recent highs [3].
The Federal Open Market Committee remains split on the necessity of immediate action. While three members dissented in favor of a rate hike during the July meeting, others have expressed caution [1]. Fed Governor Christopher Waller previously indicated he would support a hike only if inflation data came in "hot," a condition that analysts now believe has been met [1, 2].
Pressure on the central bank is also mounting from outside the committee. President Donald Trump recently demanded that the Fed lower interest rates, aiming his comments at new Fed Chairman Kevin Warsh [2]. Despite this political noise, economists at firms like EY-Parthenon have updated their projections, now calling for a 0.25 percentage point increase next week to bring the federal funds rate to a target range of 3.75% to 4% [1].
Whether the Fed proceeds with a hike will depend on whether officials view the current disinflationary process as "satisfactory" or if they believe further tightening is required to anchor long-term expectations [1]. With the labor market showing resilience and inflation proving sticky, the central bank’s upcoming decision serves as a critical test of its commitment to the 2% target [2].

The Federal Reserve is scheduled to announce its decision regarding Fed Rates at 2 p.m. ET on Wednesday, September 16.
The Federal Reserve may increase Fed Rates because inflation rose to 3.4% in August, with core inflation accelerating to 0.3% due to rising energy costs and a record increase in wireless-phone plan prices.
An increase in Fed Rates makes borrowing more expensive for consumers, resulting in higher costs for credit cards, auto loans, and mortgages.
As of September 2026, analysts at EY-Parthenon project that a 0.25 percentage point hike would bring Fed Rates to a target range of 3.75% to 4%.
