Bitcoin slid 5.5% over five days to trade below $73,000 on Thursday, closing at roughly $72,600 after shedding nearly $5,000 since the weekend. The sell-off accelerated Wednesday when U.S. spot Bitcoin ETFs collectively bled $733.43 million in net outflows — the largest single-day withdrawal since late January 2024. BlackRock's iShares Bitcoin Trust (IBIT) alone accounted for $527.84 million of that, its second-biggest daily outflow since launch.
Wednesday's ETF Exodus
The $733 million exodus wasn't just a BlackRock story. Grayscale's GBTC shed $104.76 million, and Fidelity's FBTC lost $60.30 million. The only bright spot? Morgan Stanley's MSBT, which pulled in a modest $4.3 million. The moves marked a continuation of what JPMorgan calls the cooling of the 'debasement trade' thesis — the idea that investors pile into bitcoin as a hedge against fiat instability. With expectations of U.S.-Iran conflict resolution rising, institutional futures positions and ETF flows have both thinned.
May has been a pivot point. After two months of steady accumulation, the market shifted to net distribution in May. Year-to-date ETF accumulation has slimmed to roughly 4,500 BTC, a far cry from the pace seen in March and April.
Geopolitical Trigger
The timing of Thursday's drop wasn't a coincidence. U.S. airstrikes on an Iranian military site near the Strait of Hormuz sent bitcoin down 3.4% in 24 hours to $72,978, before it recovered slightly. The Strait is a critical chokepoint for global oil shipments, and any military action there rattles risk assets across the board. Crypto hasn't decoupled from that dynamic.
What's interesting: a massive $1.29 billion dark-pool block trade of IBIT shares went through Tuesday — 29.2 million shares — completely separate from the net outflow data. That block likely inflated trading volumes but didn't directly feed into the withdrawal numbers. It's a reminder that big institutional moves can happen in ways that don't show up in daily flow reports.
Even with Wednesday's $527 million withdrawal, IBIT still holds $64 billion in lifetime net inflows since its January 2024 debut. Wednesday's outflow was less than 1% of that total. So it's not a catastrophe — but it's a signal. The fund has seen only two larger single-day outflows in its history, and both came during broader market stress.
The big question now is whether the selling has a catalyst beyond geopolitics. JPMorgan's note suggests the 'debasement trade' is losing steam as the odds of a U.S.-Iran deal improve. If that thesis holds, ETF inflows may stay muted until something shifts — either a new macro fear or a catalyst that reignites the narrative. For now, the market is waiting.
