Bitcoin ETF Outflows Deepen as $80K Falters
The latest outflows followed a sharp wave of buying earlier in September. On September 3, U.S. spot Bitcoin products attracted about $730.9 million, marking their largest single-day inflow since January. BlackRock’s IBIT accounted for about $454 million of that total.
Flows weakened after the U.S. holiday weekend. On September 8, Grayscale’s GBTC recorded about $65.5 million in outflows. Fidelity’s FBTC and Invesco’s BTCO also posted withdrawals. BlackRock’s IBIT added about $10.7 million, while Bitwise’s BITB attracted roughly $14.5 million.
Bitcoin also faced renewed price pressure as ETF withdrawals returned. The cryptocurrency slipped below $80,000 earlier in the week before trading around $79,000 on September 9. The move came as investors assessed inflation risks and the outlook for U.S. interest rates.
Treasury yields moved higher as markets prepared for fresh inflation data and the Federal Reserve’s September 16 policy decision. Brent crude also climbed above $100 per barrel amid escalating Middle East tensions, adding another source of inflation concern.
BTC ETF Flows Remain Positive for September
The two-day outflow streak shows that demand can shift quickly when broader markets turn cautious. However, the monthly total remains positive because of large inflows in the first week of September.
Bitcoin ETFs therefore enter the next trading sessions with mixed flow signals. Investors are watching Bitcoin’s ability to hold near $80,000, while upcoming inflation data, Treasury yields, oil prices, and the Federal Reserve decision remain central market factors. Those factors may guide near-term allocations as institutions reassess risk before the Federal Reserve’s next policy announcement.
