Warsh's hawkish debut fuels bets on 80% September rate hike

The Federal Reserve held its policy rate at 3.50%-3.75% in June, but Chair Kevin Warsh's unambiguously hawkish tone shifted market expectations toward a rate increase as soon as September.

"Warsh's stance will increase short-end US Treasury volatility and flatten the long-end curve," said Haigh Kay Haigh, global head of fixed income and liquidity solutions and chief investment officer at Goldman Sachs Asset Management.

Traders now price more than an 80% probability of a quarter-point hike at the Federal Open Market Committee's Sept. 15-16 meeting, according to overnight index swap markets. The median 2026 policy rate forecast in the Summary of Economic Projections rose to 3.8% from 3.4% in March, with half of the 19 officials projecting at least one rate increase before year-end.

The shift in rate expectations threatens to tighten financial conditions just as the economy shows signs of slowing. The 2-year Treasury yield climbed 8 basis points following the decision, while the 10-year yield remained relatively anchored near 4.15%, steepening the yield curve. The Bloomberg Dollar Spot Index rose 0.3% as traders repriced the path of US interest rates relative to other developed economies.

A Break From the Powell Playbook

Warsh, who took office in May after President Donald Trump nominated him to succeed Jerome Powell, used his first press conference to distance himself from the previous administration's approach. He announced five task forces to review Fed communications, the balance sheet, the discount window, the monetary policy framework, and the payments system — with most expected to deliver recommendations by year-end.

Notably, Warsh did not submit his own projections to the SEP, and he emphasized that the committee is not bound by the forecasts published Wednesday. He criticized the central bank's forecasting record, saying inflation has remained stuck above the 2% target since the pandemic and that the Fed would not tolerate persistently high price pressures.

The last time a Fed chair used a debut press conference to signal a policy pivot was in 2022, when Powell began the most aggressive tightening cycle in four decades. The S&P 500 fell 18% over the subsequent six months as the fed funds rate rose from near zero to above 5%.

Rate Differentials Widen as Markets Reprice

The divergence between Warsh's hawkish rhetoric and the hold decision has created unusual dynamics in rate markets. Short-dated Treasury options implied volatility surged to the highest since the March 2023 banking turmoil, according to data from CME Group. Meanwhile, long-dated yields remained anchored as investors bet that any rate increases would ultimately slow the economy and force cuts later.

The current fed funds rate of 3.50%-3.75% reflects 75 basis points of cuts from the peak of 4.25%-4.50% reached in early 2025, when the Fed last changed rates. Markets had entered 2026 pricing three additional quarter-point cuts by December; those expectations have now been replaced by bets on at least one hike.

For investors, the key question is whether Warsh's hawkishness represents a genuine shift in the reaction function or a strategic attempt to rebuild credibility after years of inflation overshoot. The July FOMC meeting will provide the next clue, with the statement and press conference offering the first opportunity to see whether the committee's hawkish lean translates into action.
