June outflows from U.S. spot Bitcoin ETFs deepen; flows seen stabilizing by mid-month

BlockBeats, June 8 — U.S. spot Bitcoin ETFs posted a net outflow of $1.72 billion last week, the largest weekly withdrawal since February 2025. BlackRock's IBIT, the spot Bitcoin ETF with the biggest net assets, saw $1.34 billion leave the fund over the week, its largest weekly outflow since launching in January 2024. The category has remained in an outflow phase that began in May. May ended with total net outflows of $2.43 billion. Andri Fauzan Adziima, Head of Research at Bitrue Institute, attributed the latest ETF selling primarily to macro headlines, led by recent U.S. labor data. A strong May 2026 nonfarm payrolls report underscored labor-market resilience, lowered expectations for near-term Federal Reserve rate cuts, and lifted U.S. Treasury yields, making yield-bearing bonds more compelling versus non-yielding Bitcoin. Geopolitical uncertainty has also fueled broad risk-off positioning in recent sessions, weighing not only on digital assets but also areas such as artificial intelligence, technology stocks and gold. Adziima expects outflow pressure to persist into early June, then stabilize or edge positive by mid-to-late June as panic fades, seasonal June tailwinds emerge and any easing in macro conditions could draw capital back into the space.
