Federal Reserve Chair Kevin Warsh appears to have handed markets a clear signal that interest rates could rise again as early as September, triggering a sharp repricing of rate expectations across Treasury markets and equity indices. Fed funds futures contracts now imply a roughly 68 percent probability of a 25-basis-point increase at the September meeting, up from below 40 percent earlier in the month, according to data tracked by CME Group. The shift follows a series of public remarks in which Warsh underscored that inflation remains insufficiently subdued to justify any easing in the central bank’s restrictive stance. As reported by CNBC markets, traders now see the Fed chair as having tacitly endorsed another tightening move, even if he stopped short of explicit guidance.
The latest read on core personal consumption expenditures, the Fed’s preferred inflation gauge, showed prices rising at an annual rate of 3.1 percent in July, comfortably above the central bank’s 2 percent target. Warsh has repeatedly framed price stability as the non-negotiable foundation of Fed credibility, a position he elaborated on at Jackson Hole earlier this month. The Fiscalist previously covered how his Jackson Hole address drove initial rate-hike odds higher and raised the prospect of friction with the Treasury Department over the pace of tightening.
Bond Markets and the Dollar React Swiftly
The repricing of rate expectations rippled immediately through fixed-income markets. The yield on the two-year Treasury note, the maturity most sensitive to near-term monetary policy shifts, climbed to 5.18 percent on Monday, its highest level since March. The ten-year yield rose more modestly to 4.74 percent, compressing the yield curve inversion by just four basis points and suggesting traders are not yet convinced that a September hike would necessarily extend into a prolonged tightening cycle.
The dollar index rose 0.6 percent against a basket of major currencies, reflecting the attractiveness of dollar-denominated assets at higher yields. Equity markets were less enthusiastic. The S&P 500 fell 0.9 percent in early trading as rate-sensitive sectors led the decline, with real estate investment trusts dropping 2.1 percent and utility stocks down 1.7 percent. Technology shares also retreated, with the Nasdaq Composite shedding 1.2 percent as the prospect of sustained higher discount rates weighed on long-duration growth valuations.
Skeptics Question Whether September Is Truly in Play
Despite the market move, a meaningful contingent of economists and strategists caution against reading too much into Warsh’s language. Several Wall Street research desks noted that Warsh’s remarks, while hawkish in tone, contained significant conditionality around incoming labour market data. August payrolls figures, due to be released days before the September meeting, are widely expected to be the decisive input. A print below 150,000 net new jobs could be sufficient to pause the committee, analysts at several major banks argued in published notes this week.
The broader dissent centres on whether the Fed can justify another hike without risking a meaningful slowdown in credit-sensitive sectors of the economy. Commercial real estate stress, which has been building since early 2025, remains an unresolved vulnerability on bank balance sheets. The labour market, while still resilient, has shown tentative signs of softening, with the four-week moving average of jobless claims edging up to 231,000. The Fiscalist’s earlier coverage of July payrolls data detailed how Warsh drew on that report to support a cautious stance on rate cuts — a framework that now cuts the other way for those arguing against an imminent hike.
Political context adds another layer of complexity. Treasury Secretary Scott Bessent has signalled a preference for lower borrowing costs to ease the federal government’s debt servicing burden, which has climbed sharply as higher-for-longer rates feed through to rollover costs. Any public divergence between the Fed and Treasury ahead of a September vote would inject additional volatility into markets already sensitive to policy signals. For now, the weight of market positioning suggests traders are taking Warsh at his word — but with one eye firmly fixed on the data between now and decision day.
