The Treasury Department doubles its liquidity support for longer-dated bonds through November 2026 to enhance market stability.
The U.S. Treasury Department will increase its maximum buyback size for longer-dated nominal coupon securities to at least $4 billion per operation, up from $2 billion. The change applies to 10-to-20-year and 20-to-30-year sectors and takes effect September 9, lasting through November 4, 2026.
The move aims to bolster liquidity in segments where high-quality offers have been consistently strong. Treasury cited robust market participation as justification for the adjustment, with plans to revisit sizing at the November 2026 Quarterly Refunding.
Yields on longer-dated Treasuries fell after the announcement. The 10-year note yield dropped 6 basis points to 4.647%, while the 30-year bond yield declined 9 basis points to 5.196%.
