U.S. Spot Bitcoin ETFs See $296 Million Weekly Outflows as Macro Jitters Rise

U.S. Spot Bitcoin ETFs Reverse Course

U.S. spot bitcoin ETFs posted $296 million in net outflows for the week ending March 27, according to SoSoValue data. The withdrawals reduced total net assets for these vehicles from a peak of $91.7 billion on March 23 to $84.8 billion by the close on Friday, a 7.5% decline over the period.

The weekly outflows were concentrated on March 27, when the products saw a $225.5 million one-day exodus, the largest single-day loss of the week. BlackRock’s IBIT fund accounted for $201.5 million of that total, marking the heaviest outflow by a single fund during the five-day trading stretch.

This ETF flow volatility coincided with pronounced price swings in bitcoin. The cryptocurrency briefly traded above $71,000 mid-week before retreating to $65,000 by Friday. Early Monday, bitcoin changed hands at $67,376 after rising 1.4% over the prior 24 hours.

Global Digital Asset Flows Turn Negative

Globally, digital asset investment vehicles registered $414 million in net outflows over the same week, according to a report by CoinShares Head of Research James Butterfill. He linked the reversal to investor concerns over the prolonged nature of the Iran conflict and the risk of higher inflation, noting that June FOMC expectations have shifted from potential rate cuts to possible rate hikes.

Total assets under management (AUM) across global digital asset funds fell to $129 billion, returning to levels last seen in early February and described as broadly comparable to April 2025 during the initial phase of Trump’s tariffs. The regional breakdown showed that sentiment was notably weaker in the United States, which accounted for $445 million in outflows. In contrast, Germany and Canada saw inflows of $21.2 million and $15.9 million, respectively, as some investors increased exposure during the price pullback. Switzerland recorded a smaller $4 million outflow.

By asset class, Ethereum investment products experienced the largest global withdrawals, with $222 million in outflows for the week. This pushed year-to-date flows for Ethereum vehicles to a net outflow of $273 million, the weakest performance among major digital assets. Bitcoin-focused funds recorded $194 million in global net outflows during the week but remain positive year-to-date with $964 million in net inflows. Short-bitcoin products drew $4 million in new capital.
