Key Takeaways
- • Bitcoin ETF flows turned positive across all rolling periods tracked by Bloomberg for the first time in months, with year-to-date cumulative flows at approximately $1.8 billion, according to Ben Slavin, global head of ETFs at BNY Asset Servicing (which services 80% of the crypto ETF market).
- • The 12 spot Bitcoin ETFs recorded $335 million in cumulative one-day inflows as of Thursday morning and $2.1 billion in monthly flows, with BlackRock's IBIT fund alone accounting for $246 million of daily inflows and $1.9 billion over the past month.
- • Total spot Bitcoin ETF assets under management stand at approximately $125 billion, down from an all-time high of $162 billion in October 2025 when Bitcoin traded above $120,000, indicating volumes remain muted compared to prior year levels.
- • Geopolitical tensions in Iran and inflation concerns triggered significant outflows throughout March, particularly toward month-end, creating headwinds that the market has now recovered from.
- • Grayscale Bitcoin Trust remains an outlier with year-to-date outflows of $960 million and one-day outflows of $16 million, while most other spot Bitcoin funds are recording positive inflows.
Summary
Bitcoin spot ETFs have reversed their earlier 2026 momentum, with all tracked flow metrics returning to positive territory for the first time in several months. According to Bloomberg Senior ETF Analyst Eric Balchunas, "every single rolling period" tracked is now positive—a milestone not achieved since the beginning of the year. Ben Slavin, global head of ETFs at BNY Asset Servicing (which services 80% of the crypto ETF market), confirmed this inflection point in an interview with The Block, stating that "flows have turned positive for the year" and are now "in the green, not in the red," though he characterized the recovery as "modest."
The quantitative picture reflects sustained recovery momentum. Across the 12 spot Bitcoin ETFs, cumulative one-day inflows totaled $335 million as of Thursday morning, while monthly inflows reached $2.1 billion. Year-to-date and three-month flows stand at approximately $1.8 billion, a figure that represents recovery from the extended period of outflows recorded at the beginning of 2026. BlackRock's IBIT fund, the largest spot Bitcoin ETF by valuation, dominates the inflow picture, contributing $246 million of daily inflows and $1.9 billion over the past month. Most other spot Bitcoin funds are also showing positive flows, with the notable exception of Grayscale Bitcoin Trust, which recorded $960 million in year-to-date outflows and $16 million in one-day outflows.
However, the broader asset base remains constrained. Total spot Bitcoin ETF assets under management currently stand at approximately $125 billion, substantially below the all-time high of $162 billion recorded in October 2025 when Bitcoin traded above $120,000. Trading volumes have also remained muted relative to prior-year comparisons, according to data from The Block. The near-term outflow period was exacerbated by geopolitical tensions centered on Iran and rising inflation concerns, which triggered significant capital departures throughout March, with particularly acute outflows toward month-end.
Slavin noted a behavioral distinction among crypto ETF traders, observing that they display greater willingness to hold positions through significant drawdowns compared to traditional ETF investor cohorts. This retail and institutional resilience has likely contributed to the current stabilization and flow reversal, despite elevated macroeconomic uncertainty.
