Dollar hits 17-month high versus euro as bond selloff lifts yields

The U.S. dollar reached a 17-month peak against the euro on October 1, 2025, as government bond sales in the United States and Europe caused a surge in Treasury yields to record highs. Inflation rising globally, particularly due to surging energy prices and fiscal policy concerns, contributed to the uptick in bond yields. The euro declined by 0.79% to $1.1238, marking its lowest level since May 2025, while the dollar gained 0.57% during the day.

The yield on the U.S. 10-year notes peaked at 5.272%, its highest level since 2002. The euro also weakened against other major currencies, including the yen, the Swiss franc, and the pound. Inflation data released on Wednesday showed that U.S. inflation rose slightly less than anticipated in August, prompting expectations of a Federal Reserve rate hike later in the month.
