Fed's Warsh leaves traders guessing with 30% chance of July hike

Days before the Fed's July 29 decision, swap markets still cannot agree on whether rates will move — a level of pre-meeting uncertainty unseen in modern central banking.

Chair Kevin Warsh's abandonment of forward guidance has left bond traders guessing until the final days before the July 29 FOMC decision, with swap markets pricing just a 30% probability of a quarter-point hike against a 70% chance of a hold.

"No forward guidance means we'll regularly see 20%, 30%, 40% probability distributions," said Jim Bianco, president and macro strategist at Bianco Research. "The market is transitioning to this new way of thinking."

The uncertainty has already amplified bond market volatility. The US 10-year yield stood at 4.55% after rising 0.9 basis points on July 17, a session when stocks fell and oil surged — an unusual combination that reflects inflation fears rather than recession concerns. The S&P 500 dropped 1.01% to 7,457.69 while Brent crude jumped 4.59% to $88.10 a barrel as US-Iran tensions threatened the Strait of Hormuz.

A surprise hike on July 29 would mark the first rate increase since the Fed cut to the current 3.5%-3.75% target range, potentially triggering a sharp selloff in equities and a rally in the dollar. A hold, by contrast, would only delay the reckoning: swap markets already fully price a quarter-point hike by September and imply more than two cumulative increases by March 2027.

The fog surrounding next week's decision is a direct consequence of Warsh's deliberate break with precedent. Since taking office in May, the new chair has dismantled the Fed's long-standing practice of signaling policy moves weeks in advance, arguing that telegraphed decisions box policymakers in when inflation data shifts unexpectedly. His predecessor, Jerome Powell, typically used speeches and media appearances to prepare markets — the last time Wall Street faced comparable ambiguity was September 2024, when traders debated whether the Fed would cut by 25 or 50 basis points. Powell ultimately chose the larger reduction.

Inflation data sends conflicting signals

The confusion is rooted in genuinely mixed economic indicators. The Consumer Price Index has fallen to 3.5% year-over-year from 4.2%, and core CPI has eased to 2.6% — progress that briefly led bond traders to lean against a July hike after the June CPI print showed its first decline in six years. Yet the Fed's preferred inflation gauge, the Personal Consumption Expenditures Price Index, tells a different story: headline PCE has risen to 4.1% from 3.8%, while core PCE stands at 3.4%. With the effective federal funds rate at 3.63% and CPI at 3.5%, the real policy rate sits at approximately 0.13% — barely restrictive territory by historical standards.

Warsh has repeatedly warned that inflation remains stubbornly above the Fed's 2% target, and his recent remarks linking near-term tightening to core CPI trends have kept a July hike on the table. The US-Iran escalation adds another complication: a sustained rise in crude oil prices would feed into consumer prices within months, potentially forcing the Fed's hand even if domestic data softens.

Economists and traders diverge sharply

One striking feature of this decision cycle is the gap between professional forecasters and market participants. All 76 economists surveyed by Bloomberg expect the Fed to hold rates steady at the July 28-29 meeting. Traders, however, see a material chance of action. "I still don't think the Fed will hike next week, but the market tells me the vote will be closer than I expected," said John Brady, managing director at RJ O'Brien.

This divergence is itself a product of Warsh's new regime. In the forward-guidance era, economist surveys and market pricing rarely diverged this close to a meeting because the outcome was effectively pre-announced. The current split means that whichever way the decision goes, a significant portion of the market will be wrong — and positioned accordingly.

For traders, the new rules mean higher potential payoffs for correct calls but steeper losses for wrong ones. Rate volatility is likely to remain elevated through the decision, with the VIX — the S&P 500's fear gauge — already at 18.77 after a 12.19% jump on July 17. The next major data point before the meeting is the July 23 initial jobless claims report, followed by the July 24 flash services PMI, either of which could shift the probability calculus in the final days.
