Iran attacked ships in the Strait of Hormuz and launched a drone strike on the Fujairah Oil Industry Zone. Brent crude jumped to $114.44 and WTI hit $106.42. Bitcoin didn't flinch — it reached an intraday high of $80,717.66 on May 4. The escalation threatens global energy supplies and tests the narrative that crypto is a macro hedge.
Oil spike and the macro backdrop
Brent crude at $114 isn't the only number moving. The 10-year Treasury yield climbed to about 4.44%, and the 30-year yield broke above 5%. Freddie Mac reported the 30-year fixed mortgage rate at 6.30% as of April 30, up from 6.23% the week before. The Strait of Hormuz handles roughly 20% of global oil and LNG supply. Eurasia Group warned that without a deal to reopen the strait, US gasoline could hit $5 per gallon. The national average was already $4.457 on May 4, per AAA.
Chevron's CEO warned physical shortages would appear. The US is releasing up to 92.5 million barrels from the Strategic Petroleum Reserve as part of an IEA effort, but crude held its gains. Gold fell 2% on May 4 despite the escalation — the dollar firmed and higher-rate expectations hardened. The IMF's Kristalina Georgieva said oil could reach around $125 if the conflict extends into 2027.
Bitcoin holds $80,000
Bitcoin's ability to stay above $80K while the 10-year yield sits near 4.45% is notable. It suggests reduced rate sensitivity, at least for now. The facts note that a breach of $80,000 would reinforce the view that Bitcoin behaves as a liquidity-sensitive risk asset when real yields rise and the dollar firms. So far it's holding.
Rate cut expectations have been pushed way out. Barclays moved its first expected Fed cut to March 2027. CME FedWatch indicated traders saw roughly a 78.7% probability of no rate change through the end of 2026. That's a long wait for lower rates. The Treasury expects to borrow $189 billion in the second quarter and $671 billion in the third quarter — more supply that could keep yields elevated.
Institutional flows keep BTC afloat
What's propping up Bitcoin? Institutional flows. BlackRock's IBIT held $63.53 billion in net assets as of May 1. That same day, US-traded spot Bitcoin ETFs recorded $630 million in inflows. That kind of steady demand provides a floor even when macro conditions look dicey. It's a different dynamic than previous cycles, when a spike in yields would've sent BTC lower.
For now, the question is whether the geopolitical shock has further to run. The Strait of Hormuz situation isn't resolved. The Treasury's borrowing calendar looms. Bitcoin at $80K may prove a staging ground — or a ceiling — depending on what happens next.
