Headed into the weekend, the dollar posted losses against both the euro and the yen, putting it on course for its first down week in over a month as bets on a Federal Reserve rate increase continued to ease and investors monitored turbulence tied to artificial intelligence stocks.

Price data on both the consumer and producer side came in above forecasts during the week, unsettling markets initially, yet remarks from Federal Reserve policymakers — indicating no pressing case for additional rate tightening — helped steady yields on Treasury securities while the dollar lost ground.

Declines across AI-linked equities rippled into portions of the credit market over the course of the week, with investors who had built up concentrated positions throughout the supply chain growing uneasy over whether data centre operators could generate returns quickly enough to service their debt obligations. Matt Weller, global head of market research at StoneX in Michigan, noted in an attributed comment that the unusually tight relationship between the US dollar and AI-sector trading had stood out to him, adding that a pullback in technology stocks would ordinarily be expected to push the dollar higher on safe-haven demand.

The dollar index — tracking the currency against a basket of six major peers — slipped 0.17% to 101.87, leaving it on course for a 0.35% loss across the week, even as a quoted source noted that bonds were drawing some of the same inflows.

Both the pound and the Swiss franc outpaced the dollar over the course of the week, with the franc drawing particular support from investors seeking shelter in stable assets alongside a broadly held view that Swiss monetary authorities are unlikely to push borrowing costs beneath the floor of zero even as global rates trend downward. Pound sterling edged up 0.31% against the dollar to reach 1.3314, posting a 0.63% advance over the five-day period, as the greenback slipped 0.25% against the Swiss franc to settle at 0.8246 — a retreat that left it 0.67% lower across the same stretch. Over the span of two trading sessions, the franc climbed by more than 1.4%.

Pricing in futures contracts tracked by the CME FedWatch Tool placed the odds of a rate hold at the current month's Federal Reserve meeting at roughly 83%, a notable climb from the 49% reading recorded four weeks prior.

Speaking at the IMF-World Bank annual meetings in Bangkok on Friday, Fed Chair Kevin Warsh withheld any indication of where borrowing costs might move next, noting that he does not form views ahead of committee deliberations, and adding that, in his assessment, there was not yet sufficient backing among members — particularly the board of governors — to support lifting rates at the October gathering. John Velis, who handles Americas macro strategy at BNY in New York, noted that the picture for December had yet to take shape, with plenty of room for conditions to shift before that point arrives.

Concerns about France's public finances, which had drawn attention when the country's debt risk premium climbed in early October, receded into the background. Trading at $1.1227, the euro held a 0.08% advance on the day, building on Thursday's 0.56% move — its strongest single-session performance in roughly two months — and pointing toward a 0.23% net gain across the week.

Market participants broadly anticipated that the Trump administration would avoid actions that deepen armed conflicts in the Middle East or Ukraine, given that prolonged warfare could drive up prices and weigh on its political standing before the midterm elections.

Trading at 158.11 yen per dollar, the US currency edged back by 0.08%, putting the yen on course for a 0.13% gain over the week — a modest recovery after four straight weeks of losses, with tensions surrounding Iran having bolstered demand for the dollar during that stretch. Crude oil's climb in value lent support to the dollar, while currencies in nations that depend heavily on imported energy — among them those linked to the euro and the yen — faced downward pressure as a result.

At a Friday briefing, Bank of Japan Governor Kazuo Ueda pointed to the possibility that underlying inflation could climb beyond the institution's 2% target.
