The Strait, The Ceasefire, and the Market's Embarrassing Optimism

RE: You've been here before. You didn't learn anything.
Let's establish the facts as they actually exist, not as the S&P 500 briefly priced them on Wednesday.
Crude oil sat between $90 and $100 a barrel at midweek after spiking above $110 in early April when Iran's blockade of the Strait of Hormuz was at its most aggressive. Markets exhaled. Trump extended the ceasefire. The Nasdaq hit an all-time high. The Russell 2000 scored a new closing record. Everyone quietly concluded that the worst was over and rotated accordingly.
Then Thursday arrived. Asian equities opened lower overnight as it became clear that US-Iran talks were making little discernible progress, and the Strait — functionally — remained closed. Oil ticked back up. Software stocks imploded for unrelated reasons. The S&P gave back 0.41%. The Nasdaq shed 0.89% after touching yet another intraday record it couldn't hold.
This is the third time since late February that markets have run the same script: escalation panic, ceasefire euphoria, tentative normalization, fresh doubt. The price of Brent has essentially been a sentiment poll dressed up in commodity clothing. And the crowd keeps voting wrong.
Here is what markets appear to have decided is the base case: that a conflict involving the United States military, the Iranian Revolutionary Guard, the Strait of Hormuz — through which roughly 20% of global oil supply moves daily — and the active involvement of Pakistani diplomacy, Houthi missiles, and a US Navy blockade is a temporary disruption. A headwind. A "tail risk," as Barclays called it in a note, even as they acknowledged that crude would race past $100 a barrel if the strait closed for real.
The strait is functionally closed right now. It has been since the blockade intensified. Iran's foreign minister briefly declared it open on April 17, oil fell more than 10% in a day, markets popped. The declaration lasted approximately as long as it took for Tehran to walk it back.
There's a word for repricing a serious structural disruption as a transient one every time a ceasefire is announced. The word is not "efficiency."
The historical parallel that keeps surfacing — and that nobody on the sell-side seems willing to press — is the tanker wars of the 1980s. From 1984 to 1988, Iraq and Iran attacked over 500 vessels in the Persian Gulf. The United States reflagged Kuwaiti tankers in 1987 and started escorting them through the gulf. Markets, after the initial shock, largely normalized. Oil didn't go to $200. The global economy bent without breaking.
The lesson most investors took from that episode: the Strait is always fine in the end.
The lesson they should have taken: the Strait was fine in the end because the United States committed sustained naval power over four years, took direct military casualties, and Iran was simultaneously being bled in a land war with Iraq and had no option but to eventually back down. The strategic context then was completely different from the strategic context now, and invoking it as precedent is lazy in a way that will eventually be expensive.
Right now, Iran has a "seriously fractured" government — Trump's own words on Wednesday, cited as justification for extending the ceasefire. A fractured government is not a government capable of delivering a durable agreement. It's a government that might agree to something Tuesday and have a different faction override it by Thursday. Which is roughly what's been happening on a fortnightly basis.
The Commodity Context analyst Rory Johnston — one of the few voices in this space who's been consistently precise rather than wishful — has been clear about the mechanics: even if the strait reopens tomorrow, the oil price relief would be immediate but partial. Supply chain bottlenecks, infrastructure damage, and production outages would keep Brent anchored in the $80–$90 range at best. There is no snap-back to $70 crude. That world is gone.
Markets are not pricing that. They are pricing a ceasefire that holds, a deal that gets done, and a return to something like normalcy by Q3. That's not analysis. That's hope wearing a Bloomberg terminal.
Meanwhile, Halliburton — the largest oilfield services company on earth, whose results are a direct readout of energy sector conditions — reported this week into a market that barely cared. United Rentals surged 23% after posting strong Q1 results and raising full-year guidance, which tells you where real capital expenditure is flowing: not into energy infrastructure bets, but into industrial and construction equipment rentals. Freeport-McMoRan printed revenues of $6.23 billion versus $5.73 billion a year ago, net income more than doubling to $881 million, and the stock fell 13%. Copper, the traditional proxy for industrial confidence, is apparently also just a headwind right now.
Bitcoin, for its part, has been sitting in the $77,000–$78,000 range all week with 58.1% BTC dominance and a Fear & Greed index at 46. The one asset explicitly designed to be indifferent to geopolitics is behaving exactly like every other risk asset — cautiously, without conviction, watching the same news feeds everyone else is watching. Some store of value.
What does a genuine resolution look like? The ceasefire expires. There is no extension. The US strikes Iranian infrastructure. Iran closes the strait for real, not functionally but legally and physically. Brent goes to $120. The Fed, which has been on hold while watching energy push core services inflation higher, suddenly faces a supply shock on top of a demand it can't read. Every earnings call guidance caveat from the past two weeks — ServiceNow's "incremental conservatism," IBM's guidance freeze, Tesla's explicit warning of negative free cash flow — suddenly looks less like prudence and more like the opening paragraph of the actual story.
Or: a deal gets done. The strait reopens. Oil falls $15 in a week. Equities rip. Everyone declares the bottom was already in, forgets the three months of volatility, and buys the next dip.
The market is currently assigning high probability to the second scenario. It is doing so despite the ceasefire visibly fraying, despite Asian equities falling overnight on fresh talk-stalling reports, despite the fact that every extension of every ceasefire has come with a new caveat and a new deadline that then gets quietly missed.
History doesn't repeat. But it does send the same memo. Repeatedly. To people who filed the last one without reading it.
Long crude. Short the consensus.
