The dollar index strengthened on Wednesday, buoyed by rising Treasury yields and positive sentiment following President Donald Trump’s announcement of major investments in AI infrastructure, which propelled the S&P 500 to a record high. Treasury yields rose 1 to 4 basis points during the session, with the 2s-10s curve steepening by 2 basis points to +31.1bp, before trimming gains after a solid 20-year auction. Optimism around U.S. economic growth, strong corporate earnings, and risk-on sentiment further supported the greenback’s appeal.

Yen Weakens as Risk-On Sentiment and Rising Yields Weigh

The yen weakened broadly, with USD/JPY climbing to a one-week high of 156.71 on EBS, driven by firming U.S. yields and favorable risk sentiment. The pair is eyeing its 21-day moving average at 157.12, reflecting ongoing investor optimism. Haven demand for the yen diminished as equity markets rallied, reducing its appeal amid the current environment.

Euro Retreats Amid Dovish ECB Commentary and Shifting Flows

The euro pulled back from a three-week high, closing 0.10% lower against the dollar. Dovish remarks from European Central Bank President Christine Lagarde and other policymakers solidified expectations for a rate cut next week, weighing on the single currency. Falling euro volatility and narrowing interest rate spreads helped limit losses, while rebalancing flows ahead of month-end offered additional support. However, the euro remains pressured below its 55-day moving average of 1.0456, with 1.06 viewed as a potential upside target if momentum revives.
