The euro edged lower against the dollar on Wednesday, with market participants holding back ahead of upcoming US inflation figures and remarks from Federal Reserve officials that could shape expectations around the trajectory of interest rate policy. Rising oil costs and lingering uncertainty over France's fiscal position kept the euro under pressure, trimming it by 0.05% against the dollar to $1.1192 and dragging it to a 16-month low relative to the pound.

The dollar index, measured at 102.50, edged fractionally higher by 0.04% against its currency basket, recovering the modest ground it had shed earlier in the trading day. Traders directed their attention toward two scheduled events: US consumer price index figures set for release at 1230 GMT, along with remarks from Federal Reserve officials that could shed light on the direction of borrowing costs.

Analysts surveyed by a prominent broadcaster had placed the month-on-month reading for September's price index at 0.6%, following a 0.4% gain in August, with the year-on-year rate projected to climb to 3.6% from the prior 3.4%. One analyst noted that the index reaching 4% on an annual basis, or a pickup in the core measure, remained a possibility worth watching.

Roberto Mialich, a foreign-exchange strategist at UniCredit, indicated that such a development would push bond yields upward and lend support to the dollar, leaving the euro at risk of slipping beneath the $1.1152 floor reached earlier in the week.

Remarks from New York Fed President John Williams — in which he told an interviewer that he saw no basis at that point for additional rate action, with 2027 rate hikes in mind — had already weighed on the dollar heading into Tuesday's session. Bowman, who holds the Fed's Vice Chair for Supervision post, put forward a position of monitoring incoming data before any further rate increases would be warranted.

According to data from CME Group's FedWatch Tool, market participants placed roughly a 78% probability on the Fed holding rates steady at the October 27–28 meeting — a reading that had climbed from 53% over the preceding month — while futures positioning reflected approximately 79 basis points of cumulative tightening expected to materialise by late 2027. The Federal Reserve had enacted a quarter-point lift in the benchmark lending rate during the previous month, bringing it into the 3.75%–4.00% band.

A scheduled remarks appearance by Federal Reserve official Thomas Barkin was set for later that afternoon. The central bank's monthly Beige Book report was also due for release.

Finance ministers and central bank governors from around the world convened in Bangkok for the International Monetary Fund and World Bank's annual meetings. Two separate voices from within the IMF conveyed concern about government borrowing: Rodrigo Valdes, who oversees the body's fiscal affairs work, noted that the organisation had sharpened its warnings to governments about mounting debt levels, while Managing Director Kristalina Georgieva pointed to the United States as a country where budgetary changes are needed to place its debt trajectory on a sounder footing. A representative of the organisation told reporters that no push from the fund toward faster deficit reduction was on the table.

French government bonds bore a disproportionate share of losses during a broad market downturn, as market participants weighed the possibility that the country's pre-election political landscape could complicate the path toward narrowing its elevated fiscal shortfall. Speaking at a Bangkok forum, European Central Bank President Christine Lagarde put the onus on France to address its debt burden through tighter budget management, a position that appeared to narrow the field of discussion around any potential ECB intervention in French bond markets to stabilise yields.

The euro slipped to its lowest point against the dollar in 17 months over the course of the week, with climbing French borrowing costs compounding pressure already building from elevated energy prices. UniCredit analyst Mialich noted that a move toward the $1.10 level remained a possibility in the near term, while expressing a less downbeat view of the currency's prospects as the year draws to a close.

Forecasts pointing to a gradual easing of US bond yields circulated alongside a separate report, published on Wednesday, that Britain's finance minister John Healey was set to cover any fresh spending commitments in the forthcoming budget through tax increases or expenditure reductions rather than additional borrowing, though analysts noted that conditions in the euro zone posed a potential drag on the euro. The pound edged up by 0.06%, with the exchange rate reaching $1.326 against the dollar. The yen weakened slightly on the day, trading at 158.46 against the dollar.
