U.S. Treasury to conduct $12.5 billion debt buyback, increasing liquidity-support operations for longer-dated securities.

The U.S. Treasury is scheduled for a $12.5 billion debt buyback operation today, aimed at repurchasing outstanding securities before maturity to enhance market liquidity. Additionally, the Treasury will increase the size of its liquidity-support buyback operations for longer-dated nominal coupon securities to at least $4 billion per operation, up from a maximum of $2 billion. This increase, covering 10-year to 20-year and 20-year to 30-year sectors, will be effective from September 9 through November 4.
