U.S. spot Bitcoin ETFs have attracted $5.3 billion in cumulative net inflows since the Treasury Department announced plans to increase long-term bond buybacks, recovering from $5.7 billion in July net outflows. The funds drew $2.4 billion last week, while Monday's $1 billion intake ranked as their ninth-largest daily inflow on record. The new flow data extend earlier reports of $2.39 billion in weekly inflows and a separate $2.84 billion six-session total, which had already returned 2026 flows to positive territory after a July deficit. Bitcoin remained sensitive to elevated Treasury yields and the Federal Reserve's hawkish policy stance, even as ETF demand and exchange withdrawals pointed to institutional accumulation.
