US Treasury is increasing by at least double the size of liquidity support buyback operations for longer-dated nominal coupon securities, from the current USD 2bln to at least USD 4bln. As of September 9th.

"Treasury will provide more information about future buyback sizes at the next Quarterly Refunding, scheduled for November 4, 2026." "This increase in buyback operation sizes reflects Treasury’s desire to provide greater liquidity support in longer-dated nominal sectors where there is consistent strong sponsorship from market participants, as evidenced by the significant volume of high-quality offers Treasury routinely receives in longer-dated buyback operations."
