Treasury's $77 Billion Reserve Drain Puts Bitcoin Liquidity on Thin Ice

The US Treasury is quietly draining $77 billion from bank reserves, setting up a potentially massive liquidity trap for Bitcoin. The Treasury's General Account has been rising at an accelerated pace, with a weekly-average increase of $81.153 billion in the week ending July 29. This comes as the Treasury's borrowing estimate for Q3 was revised upwards by $68 billion, adding to the pressure on bank reserves.

The decline in bank reserves is a concern for Bitcoin, which has historically been sensitive to liquidity changes in the market. The Aug. 5 financing details will be crucial in determining whether the pressure reaches broader risk appetite. A bill-heavy plan could tighten money markets, while more coupon supply leans on demand for longer-dated debt.

Roberto Perli, SOMA Manager, warned in his personal capacity that heavy net bill issuance in July and August 2026 could tighten money markets. The New York Fed's overnight reverse-repo operation accepted $2.127 billion from four counterparties last week, while the broader reverse-repo average was $343.947 billion for the week ended July 29.
