Spot bitcoin exchange-traded funds experienced significant outflows on Thursday, with investors withdrawing $635.6 million as risk-off sentiment emerged following geopolitical tensions in the Middle East. Data from Farside Investors indicates that BlackRock’s iShares Bitcoin Trust led the redemptions with over $254 million, followed by Fidelity’s Wise Origin Bitcoin Fund, which lost nearly $218 million. Other funds, including ARK 21Shares, Morgan Stanley, and Bitwise ETFs, also saw substantial withdrawals totaling hundreds of millions combined.
The sell-off coincided with a spike in oil prices after Yemeni rebel group the Houthis attacked Saudi Arabia, raising concerns about energy supply disruptions. Brent crude reached its highest price in five months, contributing to broader market anxiety. This geopolitical flare-up reversed earlier positive momentum, as bitcoin ETFs had recorded net positive investments of over $439 million earlier in the week. The immediate impact was downward pressure on bitcoin's price, which briefly dropped below $81,000 before rebounding to trade near $81,669, representing a 1% decline over a 24-hour period.
Analysts suggest that higher oil prices can negatively affect 'risk-on' assets like bitcoin by increasing the likelihood of U.S. central bank interest rate hikes. Bitcoin typically performs well in low-interest-rate environments due to increased liquidity. Despite the short-term volatility, some data points indicate a potential return to a bull market, with bitcoin crossing above its 365-day moving average last month. However, the asset remains below its October 2025 record of $126,080, having recovered from significant liquidation events later that year.
The sharp reversal in bitcoin ETF flows highlights the asset's continued sensitivity to macroeconomic factors and geopolitical risks, particularly those affecting energy markets. While institutional adoption through ETFs has provided new avenues for investment, these vehicles remain subject to traditional risk-off dynamics where rising oil prices signal potential inflationary pressures and subsequent monetary tightening. The correlation between Houthi attacks, oil spikes, and crypto sell-offs underscores that bitcoin is not yet decoupled from global commodity shocks and central bank policy expectations.
Market structure implications are evident in the concentration of outflows within major issuers like BlackRock and Fidelity, suggesting that large-scale institutional players may be adjusting positions rapidly in response to external triggers. Although analysts point to technical indicators such as the 365-day moving average crossover as signs of a bullish trend, the immediate reaction to geopolitical news demonstrates that sentiment-driven volatility still dominates price action. Investors should monitor whether this dip represents a temporary correction within an emerging uptrend or a deeper structural shift driven by sustained high-interest-rate expectations.
