Warsh's Hawkish Jackson Hole Debut Sends Dollar Broadly Higher

The Dollar Index changed hands at 99.6340, up 0.57% on the day, as of the early Sydney morning read — that move sits inside Friday, August 28's New York session, which was still about three hours from its close and had not yet finished. The impulse came from Federal Reserve Chair Kevin Warsh's first Jackson Hole address, where he said recent US inflation readings, while "better than expected," "do not tell me that underlying trends have meaningfully improved," adding the Fed still has "work to do" if above-target inflation persists. Trading Economics characterized the remarks as hawkish, and they sparked broad dollar buying across the majors, with equities easing modestly and gold and silver down sharply as the repricing rippled through markets.

Treasury yields moved higher into Friday's session: the 5-year added 9.2bp to 4.488%, the 10-year rose 5.6bp to 4.728%, the 3-month added 5.4bp to 3.732%, and the 30-year ticked up 1.6bp to 5.207%. The moves tracked Warsh's Jackson Hole remarks, delivered against a policy backdrop where the Fed funds target sits at 3.50-3.75% and the live debate is whether the Fed hikes further, not whether it cuts. Warsh's line that summer inflation prints don't show underlying improvement, plus his warning of more work to do, pushed market-implied odds of a September hike from about one-in-three to roughly 56%, according to CME FedWatch data cited by CNBC — a real repricing, not just a yield wobble.

EUR/USD slipped to 1.1581 (-0.61%), reversing off Thursday's highs even as French (2.7% y/y) and Spanish (4.5% y/y) August inflation prints ran hot; the pair remains up roughly 1.00% for August per Trading Economics. GBP/USD eased to 1.3530 (-0.46%), building on the last completed session's more-than-one-week low near 1.3582 and putting sterling on track for its first weekly loss in over a month. USD/JPY climbed to 160.18 (+0.49%), with yen weakness persisting despite Bank of Japan Deputy Governor Ryozo Himino's August 27 comments flagging upside price risk. USD/CAD rose to 1.3906 (+0.37%), pulling off its August 21 three-month low near 1.376 despite Canada's Q2 GDP growing 3.3% annualized.

GBP/USD is changing hands at 1.3530, down 0.46% as Friday's New York session runs its final hours. In the last completed session sterling eased to about 1.3582, a more-than-one-week low, putting the pound on track for its first weekly loss in over a month — near 0.4% — even though it remains higher for the month overall. The driver was dollar-led: Warsh's Jackson Hole remarks pushed market-implied odds of a September Fed hike from about one-in-three to above 50%, according to CME FedWatch data cited by CNBC. Compounding the move, falling Brent crude eased UK inflation concern, pushing market pricing for the Bank of England's next hike out to early 2027 from late 2026. BoE Governor Andrew Bailey and MPC external member Catherine Mann both attended Jackson Hole, with Mann speaking Friday; no sterling-specific comments were found. Monday's UK Summer Bank Holiday closes London, leaving thin liquidity into next week.

Today's calendar (Sydney time) shows the G20 Meetings at 01:15 and a Jackson Hole Symposium entry at 02:15, both flagged as next-day low- and medium-importance items — but the symposium (August 27-29) is already underway and wrapping up, with Warsh's market-moving keynote already delivered Friday, so that entry is a residual calendar marker rather than a fresh forward catalyst. Further ahead: Eurostat's flash euro-area HICP for August is due Monday, August 31, alongside the UK's Summer Bank Holiday, which closes London markets and thins liquidity. The Bank of Canada delivers its rate decision Wednesday, September 2, with markets expecting a hold at 2.25%, followed by the US August employment report on Friday, September 4. The European Central Bank meets September 10, and the Bank of Japan's policy meeting runs September 17-18.
