Long-end Treasury buybacks push yields higher as debt swells

Bond yields edged higher after the Treasury Department doubled the size of its long-end debt buyback program, lifting the 30-year yield to about 5.23% and the 10-year to about 4.67%, while the 2-year held around 4.17%. The move followed an earlier sharp slide and comes as yields have been rising since June; traders also digested July Fed minutes amid inflation remaining above the 2% target and the total U.S. debt surpassing $40 trillion.
