The U.S. Treasury plans to repurchase up to $6 billion in longer-term debt tomorrow as part of its ongoing liquidity management operations. The buyback will target longer-dated securities, supporting market functioning while helping the department manage cash balances. It will be another operation under the Treasury's systematic buyback program, which is intended to improve liquidity in less-traded segments of the government bond market. Regular interventions help stabilize pricing and improve secondary-market efficiency for long-duration Treasuries.
