1528 ET - The U.S. Treasury buys back its full $6 billion target in outstanding 10- to 20-year bonds. Two issues maturing in 2041 and 2042 were accepted, out of 41 eligible. It is the first time the department hits the maximum amount announced since Secretary Bessent said in August that it would increase long-term bond buybacks to at least $4 billion from the usual $2 billion. In two previous operations aiming at $6 billion, the Treasury ended up accepting $5.2 billion (10- to 20-year tenors) and $4.1 billion (20- to 30-year). The increased buyback aims to support liquidity.
