Treasury’s $6 billion bond intervention creates a stealth test for Bitcoin’s next move

The US Treasury has set a $6 billion ceiling for a Sept. 10 buyback of older long-dated bonds, giving dealers more room to offload inventory. For Bitcoin, the question is whether that relief can extend beyond bond trading into broader financing conditions.

The tentative schedule published Sept. 9 targets nominal Treasury securities with 10 to 20 years remaining. The ceiling is triple the previous $2 billion limit and exceeds the minimum expansion Treasury announced Aug. 19, when it promised at least $4 billion in operations.

The operation is scheduled for 1:40 p.m. to 2 p.m. Eastern, with settlement on Sept. 11. Eligible maturities span Sept. 11, 2036, through Sept. 10, 2046. The final securities list is due at 11 a.m. Eastern on operation day.

Treasury’s buyback rules describe liquidity support as a predictable outlet for selling off-the-run securities, meaning older issues. This differs from cash-management buybacks, which smooth government cash balances and bill issuance.

A May 2025 IMF working paper by Jing Zhou found modest improvements in Treasury trading liquidity and reduced dealer holdings, with stronger effects when inventories were high. That suggests an outlet for older bonds can ease the burden of carrying them and make intermediation easier.
