U.S. spot bitcoin exchange-traded funds reversed the recent positive trend with $296 million in net outflows for the week ending March 27, according to SoSoValue data. The shift in fund flows saw a 7.5% decline in total net assets for the ETFs, which fell from a March 23 peak of $91.7 billion to $84.8 billion by Friday's close.

Global digital asset investment vehicles recorded $414 million in outflows during the same week, marking the first net withdrawals in five weeks, CoinShares Head of Research James Butterfill noted in a Monday report. He attributed the outflows to investor concerns over the increasingly drawn-out nature of the Iran conflict and the prospects of higher inflation, with June FOMC interest rate expectations flipping from rate cuts to rate hikes. 

Total assets under management across global funds declined to $129 billion, revisiting levels last seen in early February and broadly comparable to April 2025 during the initial phase of Trump’s tariffs, per the report. 

Regionally, the negative sentiment was concentrated in the United States, which accounted for $445 million of outflows, while funds in Germany and Canada logged inflows of $21.2 million and $15.9 million, respectively, as some investors bought the dip. Switzerland recorded a smaller $4 million outflow, according to the report.

Meanwhile, Ethereum investment products recorded the largest global withdrawals of $222 million, pushing their year-to-date flows to a net outflow of $273 million — the weakest among major digital assets.

Bitcoin-focused funds saw $194 million in global net outflows for the week but remain in positive territory year-to-date with $964 million in net inflows, according to CoinShares. Short-bitcoin products added $4 million in inflows.

The weekly outflow from U.S. spot bitcoin ETFs was driven by a $225.5 million exodus on March 27, the heaviest single-day bleed of the week, according to SoSoValue data. BlackRock’s IBIT fund shed $201.5 million on that day alone, the largest single-fund outflow over the five-day trading period.
