Traders see over 66% chance of Federal Reserve rate hike at September meeting

The odds of a Federal Reserve rate hike this month have jumped past 66%, according to federal funds futures trading as of September 1. That figure represents a sharp climb from where markets stood just a week earlier, when probabilities hovered in the 35-57% range.

The catalyst is no mystery. Fed Chair Kevin Warsh took the podium at the Jackson Hole Economic Symposium on August 28 and delivered remarks that left very little room for interpretation. Inflation, he said, remains a problem that demands action.

Warsh’s Jackson Hole pivot

The core message from Warsh was blunt: the Fed’s preferred inflation gauge is sitting at 3.7%, nearly double the central bank’s 2% target. That gap isn’t narrowing fast enough for comfort.

Warsh emphasized that restoring price stability requires concrete measures, not patience.

Before Jackson Hole, rate hike expectations had actually been softening. Weak July employment numbers pushed the implied probability of a September hike down to as low as 30% at one point. Traders were starting to price in the possibility that the Fed might hold steady, letting economic cooling do some of the work.

Then Warsh spoke, and that narrative collapsed in about 48 hours.

The next FOMC meeting runs September 15-16, giving markets roughly two weeks to digest any additional data before the decision.

Bond markets are already adjusting

The Treasury market hasn’t waited for the official announcement. The 10-year yield climbed to approximately 4.76%, its highest level since January 2025.

That move tells a straightforward story. When traders expect the Fed to raise short-term rates, longer-duration bonds need to offer more yield to remain attractive. The result is higher borrowing costs across the economy, from mortgages to corporate debt.

For context, a 25-basis-point hike, which is what futures are pricing in, would push the federal funds rate higher at a time when many sectors of the economy are already feeling the strain of elevated rates.

What a rate hike means for markets

A September rate hike would carry significant implications across asset classes. Equities, which have been trading in a tense standoff between earnings resilience and rate fears, would likely face renewed selling pressure. Growth stocks are particularly vulnerable because their valuations depend heavily on discounting future cash flows, and higher rates make those future dollars worth less today.

Fixed income markets would see continued repricing. The 4.76% level on the 10-year Treasury is already elevated, but a confirmed hike could push yields even higher as the market begins pricing in the possibility of additional tightening beyond September. The Fed’s dot plot and forward guidance at the September meeting will matter almost as much as the rate decision itself.

The dollar, meanwhile, tends to strengthen when rate hike expectations rise. A stronger dollar creates headwinds for multinational earnings and puts pressure on emerging market economies with dollar-denominated debt.

Warsh clearly believes inflation at 3.7% demands a response regardless of labor market softness.

The two weeks between now and the September 15-16 FOMC meeting will be filled with data releases and Fed commentary that could shift the 66% figure in either direction. A surprisingly weak August jobs report could give doves ammunition to argue for a pause. Conversely, another hot inflation print would likely push the probability even higher and make a hike feel inevitable.
