Bitcoin exchange-traded funds (ETFs) posted $465 million in net outflows over the past two days, reversing a seven-day run that had pulled in more than $1 billion. The selling was led by BlackRock's IBIT fund, and analysts point to renewed U.S.-Iran tensions along with fresh fears that the Federal Reserve could hike rates again as the catalysts.
What drove the reversal
The outflows mark the first significant pullback from Bitcoin ETFs since early July. After a stretch of steady inflows that pushed cumulative net flows past $18 billion, the mood shifted abruptly this week. Traders and fund managers cited escalating rhetoric between Washington and Tehran, alongside stronger-than-expected U.S. economic data that revived talk of another rate increase before year-end. The combination hit risk assets broadly, and Bitcoin ETFs were no exception.
IBIT takes the biggest hit
BlackRock's IBIT, the largest spot Bitcoin ETF by assets, accounted for the bulk of the two-day exodus. The fund saw roughly $280 million in net redemptions, according to data compiled by Bloomberg. Other major products, including Fidelity's FBTC and the Grayscale Bitcoin Trust, also recorded net outflows, though at smaller magnitudes. The selloff erased about a third of the gains IBIT had made during the prior week's rally.
The $1 billion inflow streak that preceded this week's reversal had been fueled by optimism around a potential U.S. strategic Bitcoin reserve and a more crypto-friendly regulatory environment. That narrative took a back seat as geopolitical headlines dominated. The U.S.-Iran tensions — centered on new sanctions and military posturing in the Strait of Hormuz — pushed oil prices higher and sent investors toward safe havens. Meanwhile, the Fed's July meeting minutes, released last week, showed officials still open to further tightening if inflation doesn't cool. For Bitcoin ETFs, that's a double whammy: higher rates make yield-bearing assets more attractive, and geopolitical uncertainty often triggers broad risk-off moves.
ETF analysts are watching for whether the outflows deepen or stabilize. The next major test comes Friday, when weekly flow data from the U.S. Securities and Exchange Commission will show the full picture. If the selling continues, it could signal a broader shift in sentiment. For now, the $465 million figure is a reminder that even the most popular crypto products remain sensitive to macro shocks.
