0938 GMT - U.S. Treasury yields edge lower in European mid-morning trade while the dollar is steady as investors digest the Treasury's decision to increase long-end debt buybacks and its plan to economically isolate Iran. "Financial markets are heading into a heavy run of catalysts following their reaction to Treasury Secretary Scott Bessent's moves on long-dated Treasury buybacks and the latest sanctions against Iran," says the The Revacy Fund's Zaheer Anwari in a note. Treasury yields remain at elevated levels as markets await the next round of U.S. economic data, he says. The 10-year Treasury yield falls 1.6 basis points to 4.886%. The DXY index is stable at 99.028.
