July CPI at 2.5% core could decide Fed's September rate path

July's core CPI is expected to cool to 2.5% from 2.6% in June, a reading that could determine whether the Federal Reserve raises rates at its September meeting or waits until December. The report lands a week after July's jobs data showed a surprise loss of 23,000 positions, complicating the Fed's inflation fight.

"Even a low CPI print might not be enough to negate the concerns of the Fed's hawks, which focus on the durability of above-target inflation for the past four years," said Thierry Wizman, global FX & rates strategist at Macquarie Group. "But could the data push the FOMC to delay the rate hike to December? Yes, it could."

CME FedWatch data shows a near coin-flip for September: 50.3% probability of unchanged rates versus 49.7% for a hike to between 3.75% and 4%. By December, the spread widens dramatically — 43.2% for a hike to 3.75-4%, 31.3% for 4-4.25%, and 6.8% for 4.25-5%. Oil prices surged roughly 21% in July after Iran-related conflict disrupted energy markets, while 30-year Treasury yields hover near 20-year highs.

The stakes are high for advisors and their clients. A benign CPI report could give the market "permission to run faster," said Bob Edwards, chief investment officer at Edwards Asset Management. But a hot print would strengthen the case for a September hike, with five major inflation reports due before the Sept. 15-16 FOMC meeting.

The Fed has held the fed funds rate at 3.5-3.75% for five consecutive meetings since its last cut in December 2025. Cleveland Fed President Beth Hammack dissented at July's meeting, arguing the current range is not "meaningfully restricting" the economy. "When I'm talking to businesses, I'm not hearing that they're sensing any restraint from investments in growth based on where interest rates are," she told Yahoo Finance. "So to me that says that now is the time to act."

Hammack said she anticipates more than one rate hike will be required to bring inflation back to the Fed's 2% target. The Fed's preferred gauge, core PCE, stood at 3.3% in June, well above target. Long-term inflation swaps still imply 2.4% average inflation, a persistent market concern about price pressures.

What a tame print would mean

If core CPI comes in at 2.5% or lower, it would mark two straight months of declining inflation — the first time that has happened since the Fed's tightening cycle began. Wizman noted that even a low print might not fully satisfy the hawks, but it could push the FOMC to delay any hike to December, when the Fed issues a new dot plot and Summary of Economic Projections. The December meeting becomes a natural focal point for policy changes because the Fed will update its individual rate projections from 19 officials.

For advisors, the more useful signal may not be Wednesday's print itself but what it does to expectations heading into year-end. With FedWatch pricing a wide spread of outcomes by December, client conversations may be better spent framing rate uncertainty as a multi-meeting story — and stress-testing portfolios against a range of scenarios — rather than treating one data point as a verdict.

The last time the Fed faced a similar divergence between inflation data and labor market signals was in late 2023, when a soft CPI print preceded a prolonged pause that ultimately led to rate cuts. If history is any guide, a benign July CPI could similarly extend the Fed's hold into December — but the 21% surge in oil prices and near-record Treasury yields suggest the inflation risk is far from resolved. Equities have been sensitive to rate expectations all year, with the S&P 500's forward multiple compressing whenever the market prices a higher terminal rate.
