Bitcoin spot ETFs have recorded $5.3 billion in cumulative net inflows since the U.S. Treasury Department first announced plans to increase long-term bond buybacks. Last week alone accounted for $2.4 billion of these inflows, with Monday marking the ninth-highest single-day intake on record at $1 billion. The sustained capital influx represents a significant reversal from earlier this year when Bitcoin spot ETFs experienced $5.7 billion in net outflows during July. Current flows have now fully recovered from that drawdown and returned to positive territory as institutional demand accelerates alongside Treasury market operations.
