Warsh Comments Lift Fed Hike Odds to 57.5%; Dollar and Yen Diverge on Central Bank Paths

Market expectations for a Federal Reserve rate increase of at least 25 basis points at the September 2026 FOMC meeting jumped to 57.5% following comments by Kevin Warsh, according to Reuters data published August 29, 2026 (Reuters). The repricing marks a sharp reversal from just ten days earlier, when CME probabilities had plunged to 30.6%.

The path to that 57.5% figure has been anything but linear. Tracing the implied probability reveals a market whipsawing between competing narratives all summer:

  • June 8: Roughly 40% chance of a hike by October, per CME's FedWatch tool (Reuters).
  • July 28: Approximately 40% chance of a 25 bp hike at the September meeting specifically (Reuters).
  • August 11: 50% probability, down from 58% a week earlier (Reuters).
  • August 17: Just 30.6%, down from 52.2% the prior week, according to CME (Reuters).
  • August 26: 40.1% after US data releases (Reuters).
  • August 29: 57.5% in the wake of Warsh's remarks.

Dollar Index Tracks the Probability Pendulum

The dollar's trajectory has mirrored the shifting odds with notable precision. On August 26, the dollar index rose 0.24% to 99.145, with the euro trading down 0.18% at $1.1653 (Reuters). The following day, August 27, the index edged up another 0.05% to 99.18 while the euro slipped modestly to $1.1646 (Reuters).

Earlier in the month, when hike expectations were collapsing, the WSJ Dollar Index fell 0.32% over a week to 96.12, and the Singapore dollar edged higher against the greenback in the Asian session, supported by Fed rate-cut prospects (WSJ). A separate WSJ report from August 10 noted Treasury yields and the dollar rising as markets saw nearly equal chances of a September hike or hold (WSJ).

The wider arc is visible further back. On May 18, the WSJ Dollar Index stood at 95.66, down 0.23%, with the dollar retaining scope to rise as rate-hike prospects grew (WSJ). By July 28, the index had risen to around 101 before retreating (Reuters).

Bank of Japan: The Other Side of the Trade

While the Fed debate has dominated the dollar's near-term direction, the Bank of Japan has been moving in the opposite policy direction. The overnight index swaps market was pricing in nearly a 90% chance of a rate increase at the coming BOJ meeting as of July 30 (WSJ). By August 26, the Japanese yen had risen as markets raised their expectations of the BOJ increasing rates in September (WSJ).

The yen's strength has been intermittent. On August 11, its intervention boost was already fading (Reuters), but the broader policy divergence between a potentially hawkish Fed and an explicitly tightening BOJ has created a cross-current that FX desks are still navigating.

Gold Caught in the Middle

Gold prices rose on August 17, supported by a weaker dollar and fading Fed hike expectations (Reuters). That rally aligned with the period when hike probabilities had dropped to 30.6%. With odds now at 57.5% and the dollar firming near an eight-day high, the precious metal faces the opposite setup: higher real yields and a stronger greenback, the classic headwind combination.

What the Whipsaw Tells Us

The swing from 30.6% to 57.5% in under two weeks is not a story of new economic data alone. The August 26 data releases moved probability from the low 30s to 40.1%; the subsequent jump to 57.5% followed Warsh's remarks, suggesting his commentary carried outsized signaling weight relative to the hard data. For market participants, the key risk is that this probability has moved more than 20 percentage points on what appears to be a single speaker's intervention rather than a material shift in the data flow.

The WSJ Dollar Index, it should be noted, differs from the ICE-traded dollar index referenced in the Reuters reports. The two indices use different currency baskets and weightings, which partially explains the gap between the WSJ figure of 96.12 and the Reuters-referenced index at 99.145 on near-concurrent dates. Readers comparing across sources should be careful not to treat these as identical measures.

Looking ahead, the September FOMC meeting will resolve a pricing debate that has ranged from 30.6% to 58% and back again over the course of six weeks. Whether 57.5% proves well-calibrated or another false summit, the volatility in the pricing itself is the cleaner signal: the market lacks conviction on the Fed's next move, and is lurching between data points and commentary in search of one. For positioning, that means elevated two-way risk in dollar pairs, yen crosses, and rate-sensitive metals heading into the meeting.
