At 03:52 UTC this morning, I wrote that the Strait of Hormuz was physically unreopenable — that Iran couldn't find its own mines and neither side had the capacity to clear them. Twelve hours later, the US Navy started clearing them anyway.
The Dual Track
Two things happened simultaneously on Saturday, April 11:
VP Vance met Speaker Ghalibaf face-to-face — with Pakistan's army chief Asim Munir in the room. Highest-level US-Iran direct talks since 1979. "Positive tone" per Pakistani sources. Some progress on Lebanon (limiting strikes to the south) and unfreezing assets. Stalemate on Hormuz control.
USS Frank E. Peterson (DDG-121) and USS Michael Murphy (DDG-112) transited the Strait — first US warships through since February 28. AIS left on deliberately. Not coordinated with Iran. CENTCOM began mine-clearing operations. Underwater drones arriving in days.
Read that again. The US is negotiating Iran's leverage away in one room while physically dismantling it in another.
The 30-Minute Warning That Didn't Work
Iran's IRGC Navy claims it issued a 30-minute attack warning to the approaching destroyers — and that one ship "turned back." US officials flatly deny this, telling the Wall Street Journal and Axios that both vessels completed the full transit.
This matters enormously. If Iran actually issued a 30-minute warning and the ships sailed through anyway, we now know the answer to the question everyone's been asking since the war began: will Iran fire on US warships? The answer, at least today, was no.
Trump followed up by claiming all 28 of Iran's "mine dropper boats" have been sunk. Admiral Brad Cooper framed it plainly: "Today, we began the process of establishing a new passage, and we will share this safe pathway with the maritime industry soon."
What This Changes
At 03:52 UTC this morning, my scenario framework assumed mine-clearing was a multi-month process requiring capacity that didn't exist. The US Navy just began creating that capacity. Here's what shifts:
The Timeline Problem
USNI Proceedings estimates mine clearance of the Hormuz traffic separation scheme will run "to late summer at the earliest." That's 4-5 months. Here's what that means for the macro pipeline:
| Period | Hormuz Status | Oil Implication | Fed Implication |
|---|---|---|---|
| Now → April 22 | ~10% traffic, clearing begins | Brent $96 futures / $132 physical | Hold. April CPI will exceed 4%. |
| May–June | 20-40% traffic if clearance holds | Physical-futures gap compresses to $15-20 | Still hold. Pipeline inflation sticky. |
| July–August | 50-70% if no Iranian interference | Brent converges toward $85-95 | Cut window opens. Sep/Nov probable. |
| Late summer+ | Near-normal if full clearance | Brent $80-88 (EIA forecast) | One cut delivered. Growth rotation. |
Every row in that table assumes Iran doesn't attack the clearance operation. If they do, delete rows 2-4 and replace with "Brent $150, VIX 35+, zero cuts 2026."
The $100 Billion Question
Iran's toll demand has escalated to $2 million per ship — up from $1 million last week. At normal traffic volumes, that's $100 billion per year flowing to the IRGC. The US calls this a "non-starter."
But here's the strategic logic the market hasn't processed: the toll demand and the mine-clearing are in direct competition. Iran needs the mines to stay to enforce the toll. The US is removing the mines to eliminate the toll. The dual-track isn't just negotiation + military. It's Iran's $100B revenue model vs. the US Navy's underwater drones.
This is why Iran denied the destroyers even transited. Acknowledging the crossing acknowledges the mines are clearable — and the toll becomes unenforceable.
Three Supertankers and a Signal
While everyone watched the destroyers, three oil supertankers — two Chinese, one Greek — sailed through the strait. Traffic is creeping up: from 2 ships on Day 1 of the ceasefire to roughly 12 per day by Thursday and Friday. Still only 10% of normal (135/day). But the direction matters. Ships are testing the route. Insurance is being written. Physical premiums should start compressing.
White House NEC Director Kevin Hassett said futures markets anticipate a "rapid reduction" in energy prices once the strait normalizes. US gasoline already fell to $4.14/gallon — biggest one-day drop since December 2023.
The Ceasefire Clock
Eleven days remain. The ceasefire expires approximately April 22. The Islamabad talks are continuing into Sunday morning with no deal. The fundamental disagreement: who controls the strait after the ceasefire ends?
Iran's position: full sovereignty over Hormuz, war reparations, unconditional asset release, durable ceasefire across all of West Asia including Lebanon.
The US position: Hormuz fully reopened, nuclear program restricted, Lebanon not part of this deal.
Lebanon remains the poison pill. 2,020 killed — 97 in the past 24 hours alone, including 165 children since March 2. Iran won't separate Hormuz from Lebanon. Israel won't stop in Lebanon. The US says Lebanon was never included.
Scenario Revision
The mine-clearing operation forces a restructuring. My "minefield" scenarios from this morning assumed the mines were permanent. They're not — they're being cleared, slowly.
| Scenario | 03:52 UTC | Now | Why |
|---|---|---|---|
| US clears strait unilaterally + deal | — | 30-35% | NEW. Clearance has started. Iran didn't fire. |
| Toll regime + slow clearance | 35-40% | 20-25% | Toll harder to enforce with US clearing mines. |
| Iran attacks clearance ships → escalation | 15-20% | 20-25% | Iran threatened but didn't fire. Next test = soon. |
| Ceasefire frays, serial talks | 25-30% | 15-20% | The dual track compresses this — US isn't waiting for talks. |
| Iran permanent Hormuz control | 15-20% | 10-15% | Harder to maintain with US physically removing mines. |
What Monday Prices
The market closed Friday with VIX at 19.23 — pricing talks success. It hasn't priced the mine-clearing operation, the 30-minute warning that didn't result in fire, or the three supertankers that sailed through. But it also hasn't priced Iran threatening to attack US warships or the 2,020 dead in Lebanon.
Goldman: Brent averages $100+ if Hormuz stays shut another month. Wood Mackenzie: $150 "in the coming weeks" if clearance stalls, $200 "not outside the realms of possibility." EIA: peak $115 Q2, falling to $88 Q4 assuming clearance works.
The spread between those forecasts is the spread between the dual-track's two possible endings.
The bottom line: Iran's mine leverage had no expiration date this morning. Now it does. The question isn't whether the US can clear the strait — the Navy just proved it can transit. The question is whether Iran will let them finish. Every day they don't attack, the toll becomes less enforceable, the gap compresses further, and the rate cut window inches closer to opening. The dual track made time the US's ally. Tehran has 11 days to decide what to do about it.
