The U.S. Treasury plans to repurchase up to $6 billion in long-dated bonds on Thursday, setting its planned buyback of Treasurys maturing in 10 to 20 years at triple the typical $2 billion size. The operation follows the Treasury Department's announcement last month that it would at least double longer-term bond buybacks to $4 billion. Beginning Sept. 9, 2026, the Treasury will raise the maximum size of individual buybacks in the 10- to 20-year and 20- to 30-year nominal coupon sectors through Nov. 4. Treasury Secretary Scott Bessent said long-end liquidity was very poor and indicated purchases could exceed $4 billion depending on market conditions. Treasury yields initially fell after the earlier announcement before resuming their rise amid inflation concerns, fiscal deficits and continued government borrowing.
