Bitcoin ETFs had a tale-of-two-halves kind of week. Inflows started hot at $1.44B through the first three days, then investors yanked $829M back out before Friday, leaving a net weekly total of just $619M.
The culprit, as usual when markets get nervous: geopolitics. Specifically, oil prices that spiked 60% after the US attack on Iran before settling back to around $102 a barrel. When crude surges like that, risk assets across the board tend to take a hit — and Bitcoin, for all its “digital gold” branding, still trades like a risk asset when things get ugly.
The numbers tell a clear story
According to CoinShares’ latest weekly report, the early-week flood of capital coincided directly with the US strike on Iran. Bitcoin dominated the inflows at $521M, with Ethereum and Solana also attracting meaningful capital. XRP was the odd one out, posting the only notable outflows among major assets.
Price action tracked the flows almost perfectly. Bitcoin rallied nearly 11% from $66,356 to $73,648 between March 1 and 5, per CoinGecko data. Then reality set in.
From last Thursday onward, BTC dropped roughly 8%, settling around $67,777. The pattern — fast money in, fast money out — looked less like a crisis of faith and more like professionals doing what professionals do.
“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.”
That’s Nima Beni, founder of Bitlease, framing the flows as standard position management rather than collapsing conviction. In English: the smart money grabbed a quick 11% move and locked in profits before the weekend brought more uncertainty. Textbook institutional behavior.
One notable shift from prior weeks: US investors did the heavy lifting this time around. European and Asian counterparts were comparatively quiet, suggesting the geopolitical catalyst had a distinctly American flavor given Washington’s direct involvement in the Iran strikes.
Oil is the variable nobody wanted
Here’s the thing about oil prices and crypto. When crude spikes to $119 a barrel — even temporarily — it sends shockwaves through every asset class. Higher energy costs feed into inflation expectations, which feed into interest rate fears, which make risk assets less attractive. It’s a domino chain that Bitcoin can’t dodge.
Jonatan Randin, senior market analyst at PrimeXBT, pointed directly to escalating geopolitical risks as the primary driver of late-week outflows. The Iran crisis intensified with IRGC officials confirming activity around the Strait of Hormuz — a chokepoint for roughly 20% of the world’s oil supply. That’s not the kind of headline that makes portfolio managers feel adventurous heading into a weekend.
Oil has since pulled back to $102 from its $119 peak, but it remains elevated enough to keep markets on edge. For context, crude was trading around $74 just weeks ago. A 38% sustained increase in energy prices isn’t something markets shrug off quickly.
What investors should watch
The $619M net positive figure is still healthy by historical standards. For perspective, Bitcoin ETFs saw net outflows in several weeks during late 2024. The fact that inflows survived a geopolitical shock and an oil spike — even in diminished form — suggests underlying demand hasn’t cracked.
But the risk calculus has shifted. If oil stays above $100 and Middle East tensions escalate further, expect more of the same pattern: institutional capital flowing in on dips but getting pulled at the first sign of weekend risk. Bitcoin’s correlation with traditional risk assets tends to increase during geopolitical crises, which means the “uncorrelated hedge” thesis gets tested hardest exactly when holders need it most.
Watch the Strait of Hormuz headlines closely. If shipping disruptions materialize, oil could retest $119 or higher, and the next round of ETF outflows could be significantly larger than $829M.
Bottom line: Bitcoin ETF flows remain net positive, but the margin is thinning as oil-driven macro anxiety creeps in. The early-week surge proved institutional appetite is alive — the late-week retreat proved it has limits. Until crude settles down and Iran tensions de-escalate, expect choppy, risk-managed flows rather than the sustained buying pressure bulls need for a breakout.
