Bitcoin ETFs log biggest outflows in 3 weeks as Iran war fears rise
US Bitcoin ETFs saw significant outflows of $171 million on Thursday as market participants feared another weekend escalation in the US-Israel conflict with Iran.
US spot Bitcoin exchange-traded funds (ETFs) logged $171 million in outflows on Thursday, their biggest day of redemptions since March 3, when they posted $348 million in outflows.
BlackRock’s iShares Bitcoin Trust ETF (IBIT) led the outflows with $41 million, Fidelity’s Wise Origin Bitcoin Fund (FBTC) followed with $32 million, the ARK 21Shares Bitcoin ETF (ARKB) sold $30.5 million, and Grayscale’s Bitcoin Trust ETF (GBTC) sold $24 million, according to data from Farside Investors.
The outflows follow a period of demand for Bitcoin ETFs, which attracted $1.36 billion in monthly inflows so far in March and are on track for their first month of net accumulation since October 2025, when ETFs clocked $3.42 billion in net inflows, according to Sosovalue data.
