Bitcoin ETF Flows Slip to $619M as Oil Prices Surge

Crypto fund flows told a story with two acts last week — a euphoric sprint and then a cold shower. Total weekly inflows landed at $619 million according to CoinShares' latest research report, but that number papers over a wild ride: $1.44 billion came in during the first three days alone, only to be followed by $829 million in outflows as the Strait of Hormuz closure rattled institutional risk appetite across every asset class.

Bitcoin Led Inflows — Then Gave It All Back

Bitcoin was the clear winner in the inflow column. James Butterfill, head of research at CoinShares, said in a statement that Bitcoin dominated fund activity with $521 million in net inflows, while Ethereum and Solana attracted notable secondary interest. XRP was the lone major asset to bleed — posting meaningful outflows even as altcoins broadly held up.

The price action backed the flow data. Between March 1 and 5, Bitcoin ran from $66,356 to $73,648 — a gain of nearly 11%. Then came the reversal. By late week, Bitcoin had shed nearly 8% from that peak, landing around $67,777, according to crypto fund flows data published by CoinShares.

That kind of whipsaw isn't unusual for an asset that institutional desks now treat like a liquid macro hedge. The question worth asking — is this selling, or is it position management?

Portfolio managers often put on positions early in the week, capture the move, and then trim risk before weekends or geopolitical uncertainty. That's not a crypto story — that's a capital markets story.

What Did the Strait of Hormuz Closure Do to Bitcoin?

The Strait of Hormuz closure, confirmed by IRGC officials in early March, sent oil futures surging approximately 60% in the aftermath of the February 28 U.S. attack on Iran. Crude briefly touched $119 per barrel — a level that immediately triggered broad risk-off positioning across equities, commodities, and crypto. By the weekend, oil had corrected roughly 14% to just above $102, but the damage to sentiment was already done.

Jonatan Randin, senior market analyst at PrimeXBT, told reporters that the speed of the geopolitical escalation was the key variable. "When geopolitical risk rises this quickly, institutions reduce exposure to risk assets, and crypto is no exception," he said. Georgii Verbitskii, founder of investor app TYMIO, put it more bluntly: higher oil prices feed into U.S. equity weakness, and that pressure "is now feeding directly into Bitcoin."

Illia Otychenko, lead analyst at CEX.IO, added that the first financial market reaction to any crisis is typically risk aversion — investors pulling out of volatile assets first and asking questions later. Bitcoin, for all the talk of it becoming a safe haven, is still largely trading like a risk asset in 2026.

Bitcoin has asymmetric correlation with equities — it moves with stocks on the downside but doesn't capture the same upside. Geopolitical escalation creates headwinds for risk assets broadly, and Bitcoin follows.

The Contrarian Take Worth Paying Attention To

Not everyone read last week's flows as a bearish signal. Beni offered the sharpest take of anyone quoted in the analysis. "Institutions selling Bitcoin during Strait of Hormuz closure are the last generation of finance fighting structural irrelevance," he said. "Bitcoin doesn't need permission from entities that control shipping lanes. That's exactly why those entities want Bitcoin priced as if it does."

That's a take worth sitting with. If institutions are using Bitcoin as a liquid risk asset — actively trading it around macro events — that's actually a sign of maturity, not weakness. The old narrative was that crypto would be abandoned the moment things got serious. Instead, it's being actively managed inside institutional portfolios. The exit trades are just as deliberate as the entry trades.

BitMine Immersion Technologies, meanwhile, leaned the other direction entirely. The top Ethereum treasury firm by total holdings announced on Monday that it had added approximately 61,000 ETH — worth roughly $123 million — over the prior week. Its total Ethereum holdings now sit at 4,534,563 ETH, valued at approximately $9.14 billion at a price of $2,015 per coin. Conviction plays don't get much bigger.

Where Does Sentiment Stand Heading Into Next Week?

Prediction markets tracked by Myriad — owned by Decrypt's parent company Dastan — show Bitcoin holders assigning only a 41.6% probability to Bitcoin rallying to $84,000 next. That's down from 50% just one week prior. Not a panic reading, but a clear reduction in near-term confidence.

The macro overhang is real. If oil prices stay elevated, analysts say the indirect effects matter as much as the direct price shock — sustained high oil feeds into inflation expectations, which gives central banks cover to hold rates higher for longer. That kills risk-on behavior. Capital rotates out of volatile assets and into bonds and gold. Crypto doesn't get a free pass from that dynamic.

Verbitskii summed it up plainly: "Since Bitcoin is already showing signs of structural weakness, that macro pressure could translate into additional downside for crypto if the broader market sell-off intensifies." Randin agreed, noting Bitcoin was already soft before the Hormuz story broke.

The bulls still have their argument. The early-week inflow pace — $1.44 billion in three days — showed that institutional demand didn't disappear. It just got disciplined. Whether that discipline holds through the next escalation is the real question.
