BTC ETFs see $1.6B four-day outflows

TLDR

US spot Bitcoin ETFs have just logged a rare four day streak of net redemptions totaling about $1.62 billion, adding to recent pressure on Bitcoin.

1. Spot Bitcoin ETFs in the US saw around $1.62 billion of outflows over four trading days, one of the largest and longest negative streaks since launch.
2. The outflows are tied to risk off macro conditions and a collapse in the basis trade yield that had attracted hedge funds into ETF arbitrage.
3. The key things to watch now are whether flows stabilize, how ETF AUM and basis yields behave, and whether macro nerves ease enough for institutions to re enter.

Deep Dive

1. What Happened In ETF Flows

U.S. spot Bitcoin ETFs recorded net outflows of about $1.62 billion over four consecutive trading days ending Thursday, according to SoSoValue data reported by Yahoo Finance, marking one of the largest redemption streaks since early 2024 launch of these products. The daily pattern was roughly $394.68 million last Friday, $483.38 million on Tuesday, $708.71 million on Wednesday, and $32.11 million on Thursday in net redemptions, for a total of $1.62 billion over the four days of trading in that window.

Separate flow tallies show around $1.22 billion of net outflows over the past week, also the largest weekly decline in about two months, alongside a drop in Bitcoin from recent highs near the mid 90,000s to the high 80,000s zone as reported by multiple outlets.

From a market wide view, Bitcoin ETF assets under management slipped from about $126.47 billion to $118.51 billion over roughly a week, a 6.29 percent drawdown, broadly in line with the total crypto market cap falling about 6.25 percent over seven days.

2. Why The Outflows Are Happening

Analysts tie the move to two overlapping forces: macro risk off and the unwinding of a popular hedge fund basis trade. The basis trade is a strategy where funds buy spot exposure, often via ETFs, and short futures to capture the spread between them; that spread has compressed to under about 5 percent annualized from around 17 percent a year ago, making the trade much less attractive relative to U.S. Treasuries.

Reports note that hedge funds, which may only represent 10 to 20 percent of ETF holders by weight, can still dominate short term flows as they exit these trades, contributing to the four day $1.62 billion exodus. At the same time, macro nerves around tariffs, higher yields, and geopolitics have pushed investors toward traditional safe havens, with gold at or near record levels, while Bitcoin has struggled to hold above key round numbers.

Despite this, cumulative net inflows into U.S. spot Bitcoin ETFs since launch are still positive and large, so the latest outflows look more like a sharp de risk than a full structural abandonment of the vehicle.

3. What To Watch Next

A few metrics now matter more than any single price print.

1. Daily ETF flow data: a shift from persistent outflows back to flat or modest inflows would signal that the immediate de leveraging phase is ending.
2. ETF AUM versus Bitcoins market cap: if ETF AUM stabilizes around the current roughly $118 billion level while price chops sideways, that suggests longer term allocators are still in place.
3. Basis trade yields and CME futures activity: a recovery in futures basis and U.S. futures open interest would hint that institutional arbitrage capital is returning, which typically supports ETF demand.

On the downside, if outflows accelerate again, especially across many issuers rather than being concentrated in BlackRock and Fidelity products, it would reinforce a narrative of broader institutional risk reduction rather than just a tactical unwind.

Conclusion

The $1.6 billion four day outflow streak from U.S. spot Bitcoin ETFs is a meaningful but not yet catastrophic withdrawal, driven mainly by hedge fund de risking and macro stress rather than a wholesale institutional exit. For crypto users, the balance of risk in the near term hinges less on any one price level and more on whether ETF flows and basis yields stabilize, which would give Bitcoin a better chance to rebuild momentum once macro conditions calm.
