Fed Rate Hike Odds Swing Wildly on Warsh Remarks — What It Means for Your Money

The odds that the Federal Reserve will raise interest rates by at least 25 basis points (a quarter of a percentage point) at its September 2026 meeting jumped to 57.5% after comments from Kevin Warsh, according to Reuters data published August 29, 2026 (Reuters). That's a sharp reversal from just ten days earlier, when pricing data from CME had put the chance at 30.6%.

The path to 57.5% has been anything but smooth. Traders have been whipsawed 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 path has mirrored the shifting odds with notable precision. Think of the dollar as a seesaw: when rate hike odds rise, the dollar tends to rise too, because higher rates make dollar-denominated assets more attractive. 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 (the interest rate the US government pays to borrow) 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, a derivative tool traders use to bet on where short-term rates are heading, 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). The broader policy divergence between a potentially hawkish (rate-raising) Fed and an explicitly tightening BOJ has created a cross-current that currency trading 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 (interest rates adjusted for inflation) and a stronger greenback, the classic headwind combination for gold.

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.

The broader context here is that the key risk for anyone watching these markets is that this probability moved more than 20 percentage points on what appears to be a single speaker's intervention rather than a material shift in the actual data. When pricing moves that fast on commentary rather than evidence, it is fragile.

The WSJ Dollar Index 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.
