Bitcoin Liquidity Squeezed As US Treasury Drains $77B From Bank Reserves

Woofun AI reports that Bitcoin’s liquidity environment is tightening as the US Treasury systematically drains bank reserves, creating a structural headwind for risk assets. This pressure emerges not from a single policy shift, but from the convergence of weekly reserve declines and escalating government borrowing needs.

The weekly-average reserve decline of $77.579 billion ending July 29 coincided with a $68 billion increase in the US Treasury borrowing estimate for July through September. This overlap complicates the Fed's balance sheet dynamics, as the measure tracks net borrowing while excluding SOMA auction add-on rollovers and including financing for SOMA redemptions. Gross issuance follows a different yardstick, meaning the Treasury release covers government financing broadly. Bitcoin enters the picture downstream, affected by the resulting shifts in cash and funding markets rather than direct Treasury cash flows.

Woofun AI data shows that on Wednesday, July 29, reserves stood at $2.944541 trillion while the TGA held $970.442 billion. The $81.153 billion rise in the TGA was the largest component of the $89.880 billion weekly-average increase in deposits other than reserve balances. Other Fed balance-sheet items moved simultaneously, indicating that Treasury cash was only part of the week's reserve story. Buyer funding sources determine how much pressure reaches bank reserves, while Fed operations can redirect the flow.

The Aug. 5 financing map will translate a single borrowing total into an actual financing map, with its bill-coupon split and auction sizes revealing where the weight lands. The buyback schedule completes the picture, as a bill-heavy plan's reserve effect depends on buyers' funding sources, whereas more coupon supply leans on demand for longer-dated debt. Bitcoin's next macro signal comes from this plumbing. Reserve balances after settlement will show whether the pressure reaches broader risk appetite.
