Federal Reserve Chair Kevin Warsh's address at Jackson Hole, Wyoming, on Friday triggered a sharp repricing in fed funds futures. CME Group data shows traders now assign a 58 percent probability to a September rate hike—up from 35 percent a day earlier, a 23-percentage-point jump in conviction.
The catalyst: Warsh's assertion that "short-term interest rates are the predominant tool" and his statement that he would "be hard pressed to describe broad financial conditions as restrictive." That language signaled the Fed may need to tighten further despite recent rate increases.
Bond markets repriced immediately. The two-year Treasury yield—the most sensitive to near-term Fed policy expectations—rose 13 basis points to 4.35 percent from 4.22 percent. The 10-year climbed 5 basis points to 4.72 percent. The 30-year added 2 basis points to 5.21 percent. The steepness of the two-year move relative to longer-dated yields reflects the market's interpretation: the Fed is closer to tightening than previously priced.
Equity markets absorbed the repricing with muted reaction. The S&P 500 fell 0.2 percent, the Nasdaq dropped 0.5 percent, and the Dow fell less than 0.1 percent. Bank of America strategists interpreted the restrained selling as evidence that investors view Warsh's comments as "pricing a more credible Fed"—meaning the market now expects follow-through on inflation fighting rather than continued delay.
Not all bond investors were convinced. ABN AMRO Investment Solutions and Brandywine Global Investment Management expressed skepticism about a September move, citing data volatility and uncertainty around the Fed's true reaction function.
That caution reflects recent market whipsaws. Expectations for a September hike had collapsed after July's weaker-than-expected jobs report, which showed the U.S. economy shed positions. That data had depressed hike odds to the 35 percent level before Warsh spoke—a demonstration of how sensitive fed funds pricing remains to incoming labor data.
Warsh, appointed by President Donald Trump, has signaled that market reactions should track incoming inflation and employment data rather than Fed guidance. That communication posture—emphasizing data-dependence over forward guidance—aims to reduce the market's reliance on Fed messaging and anchor expectations to observable economic conditions.
