U.S. spot bitcoin ETFs ended the week with roughly $1.26 billion in cumulative net outflows, the heaviest weekly drain since late January, capping a six-day outflow streak totaling $1.55 billion, according to SoSoValue data.
The 12 U.S.-based funds lost a combined $648.6 million on Monday alone, when bitcoin slipped below $77,000 after President Trump's latest Iran threat, the largest single-day outflow since Jan. 29. "Key culprits [are] surging Treasury yields hitting 12-month highs, a stronger dollar, and geopolitical escalation," Andri Fauzan Adziima, research lead at Bitrue Research Institute, previously told The Block.
Outflows eased after Monday but never turned positive, with the funds shedding $331 million on Tuesday, $70.5 million on Wednesday, $100.8 million on Thursday, and $105.2 million on Friday, per the data.
Spot ether ETFs took a smaller dollar hit but have seen a longer outflow streak. The nine funds posted $216 million in combined outflows across the week, bringing their consecutive outflow run to 10 sessions, the category's most sustained outflow streak since March of 2025.
That stretch has now pulled cumulative ether ETF net inflows down to $11.62 billion against $11.84 billion in net assets. That leaves the funds' net assets sitting just $223 million above their cumulative inflows.
