What Actually Happened
On April 16, Iran declared the Strait of Hormuz "completely open." Markets celebrated. The S and P broke 7,100. Oil crashed below $80. Most outlets ran "war is winding down" headlines and moved on.
Less than 48 hours later, Iran reversed course. The strait re-closed. The US Navy — which had quietly begun blockading Iranian ports on April 13 — escalated its own operations. By the end of April, shipping through Hormuz was running at about 5% of pre-war volume.
The "war is over" narrative did not survive the weekend. Most of the financial press has not caught up.
The Dual Blockade Reality
What exists right now is a dual blockade. Iran blocks the Strait of Hormuz, preventing 17 million barrels per day of normal oil flow. The US Navy blocks Iranian ports, preventing Iran from exporting any oil at all. Each side is choking the other. Each side is betting the other breaks first.
US Navy vessels have directed at least 38 tankers to turn around or return to Iranian ports since April 13. Iran has retaliated with selective enforcement at Hormuz — letting some vessels through, blocking others, charging tolls in yuan when ships do transit.
Brent crude is back above $108. WTI above $95. The relief I described in the April 16 article — and that markets celebrated — was a 48-hour head fake.
Why the Reversal Happened
Three things converged. First, the Lebanon ceasefire that anchored the "war is ending" narrative collapsed within 72 hours. Both sides resumed strikes. The "fragile truce" turned out to be a press release more than a reality.
Second, Trump canceled the Pakistan meeting between Jared Kushner, Steve Witkoff, and Iranian counterparts. The diplomatic track that markets were pricing in disappeared overnight.
Third, Iran calculated that the strait reopening damaged their leverage more than continued closure damaged their economy. Once oil dropped below $80, their export revenue was already cut in half. They had less to lose by re-closing than they thought.
The Trump Calculation
Trump is now betting that a US naval blockade can do what 50 days of airstrikes could not — break the Iranian regime through economic strangulation. Iran cannot export oil. Cannot import refined products. Cannot move goods through the strait. Cannot generate the foreign currency required to keep the regime running.
The math: at 5% of normal shipping, Iran is losing approximately $200 million per day in oil revenue. Compounding domestic protests over fuel shortages. Compounding inflation. Compounding political instability.
This is the Brian Hook playbook from the first Trump administration — maximum pressure — applied with naval force instead of just sanctions. The bet is that Iran cracks first.
Why Markets Have Not Repriced
Equity markets are still trading near all-time highs. The S and P 500 has held above 7,000. Tech earnings have dominated the news cycle. The geopolitical situation has reverted to "as bad as it was in March" but the market is acting like nothing changed.
Two reasons. First, Big Tech earnings consumed 100% of investor attention this week. Second, the AI capex story is a more powerful narrative than the war story right now. The market chooses what to look at, and right now it is choosing GPUs over geopolitics.
That ends when something makes it impossible to ignore — an Iranian attack on a US warship, a major Saudi facility hit, a sustained move in oil above $115. Until then, the disconnect persists.
The Trade Setup
If you are positioned for "war is over," you are wrong on the geopolitics and right on the markets — for now. That can flip on a single headline.
The asymmetry: limited upside if the dual blockade holds (S and P stays around 7,000), significant downside if Iran retaliates against the US blockade or hits Gulf energy infrastructure again.
Hedge accordingly. Buying oil exposure as a tail-risk hedge against the next escalation costs less than it should given the actual risk. Energy stocks are still 20% below their March highs. Defense stocks are reverting on "war is ending" narrative that does not match reality.
The market will reprice this eventually. The only question is whether it does so on a slow grind or a single catalyst.
The Honest Update
The article I wrote on April 16 about Hormuz reopening was accurate to that day. It was wrong by April 18. That is the nature of this conflict — every "deal" lasts hours, every peace announcement gets reversed, every ceasefire is "fragile." Trade the chart, not the press conference. Read the shipping data, not the Truth Social posts.
Hormuz is closed. The dual blockade is real. The war is in Day 60. None of the structural drivers have changed.
