Conventional Wisdom: The Strait of Hormuz
In Monday's post, I noted that I wasn't going to cover the conventional wisdom on the Strait of Hormuz, because it was too big a subject, and the situation was fluid. But yesterday, I ran across a Substack essay that I think provides a pretty good snapshot of the thinking over the past weekend:
At midnight Greenwich Mean Time on 5 March 2026, seven of the twelve International Group Protection and Indemnity clubs that collectively insure roughly 90% of the world’s ocean-going tonnage executed identical cancellation notices for war-risk coverage across the Persian Gulf, the Gulf of Oman, and Iranian territorial waters.
. . . In that instant, seven letters accomplished what the entire Iranian navy could not.
. . . By every traditional metric of military dominance, the campaign is succeeding.
Yet the Strait remains commercially paralysed.
. . . [T]he 31 autonomous IRGC provincial commands that replaced centralised authority after the decapitation strikes create a counterparty problem that insurers cannot price and diplomats cannot negotiate.
. . . Global seaborne trade does not run on naval protection. It runs on a layered stack of private financial guarantees. . . . This stack possesses a critical structural vulnerability: the retrocession and ILS market systematically excludes war risk. The war-risk market therefore operates under a hard capital ceiling of approximately $1 billion in annual premiums and a handful of treaty reinsurers whose aggregate capacity cannot absorb a single major total-loss event.
. . . The problem was not merely that the probability of loss was elevated. The problem was that the tail was unlimited. A single [large tanker] total loss could easily exceed $150 million for the hull, $100 million for the cargo, and virtually infinite liability for environmental pollution. Against a premium pool that writes $1 billion annually, a single major claim would consume the entire global war-risk market’s revenue.
. . . Each additional day of closure feeds new data into insurer models, raising the actuarial cost of reopening and extending the closure in a reflexive, self-reinforcing loop. The down-barrier to closure was crossed in hours. The up-barrier to reopening, measured in the time required for sustained safe conditions, actuarial recalibration, and reinsurance capital replenishment, operates on a timescale of months to years.
. . . The market is not pricing a war. It is not pricing a chokepoint closure. It is not pricing a nuclear crisis. It is pricing a legacy framework in which these events are temporary, resolvable, and mean-reverting. The mechanism analysis establishes they are structural, self-reinforcing, and regime-changing.
This analysis is thought-provoking, if not entirely coherent. What he seems to be saying is that if the Hormuz blockade persists for any reason -- he's most intrigued by the refusal of insurers to contemplate the risk of losing even a single tanker, which is complicated by the inability of all parties to negotiate reliably with 31 separate Revolutionary Guard district entities to guarantee safe passage -- there's the potential for a hyperinflationary doomsday spiral.So far, it appears that facts on the ground, or on the water, are suggesting this analysis is unnecessarily hysterical (I think the level of jargon conceals its basic huysteria, too). First, shipping is moving through the strait, at however reduced a level. Second, ships are currently being attacked, but the damage isn't catastrophic:
Three vessels have been hit by unknown projectiles in the Strait of Hormuz, maritime security agencies and sources said Wednesday, as one of the strikes led to a fire onboard a ship and forced most of its crew to evacuate it.
The Thailand-flagged bulk carrier Mayuree Naree was targeted and damaged approximately 11 nautical miles north of Oman, two maritime security sources said.
. . . Earlier, the Japan-flagged container ship One Majesty had sustained minor damage from an unknown projectile 25 nautical miles northwest of Ras Al Khaimah in the United Arab Emirates, two maritime security sources said.
Its crew members are safe and the vessel is sailing towards a safe anchorage, the sources added.
A third vessel, a bulk carrier, was also hit by an unknown projectile approximately 50 miles northwest of Dubai, maritime security firms said.
The projectile had damaged the hull of the Marshall Islands-flagged Star Gwyneth, maritime risk management company Vanguard said, adding that the vessel's crew were safe.
In other words, the reality of Iran's retaliation in the Strait of Hormuz will be equivalent to its retaliation against Israel and the Gulf states, a diminishing level of missile and drone strikes, most of which are inaccurate or intercepted. On one hnad, too many players rely on the oil that comes through the strait, especially China. On the other, the market appears to be pricing in Trump's assurances. At about 1:15 in the video embe3dded at the top of this post, Mark Halperin says,
The president did a quick interview with a correspondent from CBS News, and what happened? Before that, everybody was all up in arms about the price of gas going up and the markets going down. And the president just said a few things to CBS News, and what happened after the president spoke? . . . The Dow Jones Industrial Average was down nearly 900 points before the president said what he said, which was basically this is going to be a quick war, everything's gone so well. After he spoke, [the Dow] went from 900 down to net up 240 points for the day.
The same applies to oil prices:
US West Texas Intermediate Crude Oil Futures with April 2026 Expiry, traded at $89.89 per barrel, down by 5.2%. This oil benchmark touched an intraday low of 84.45 and recorded an overall decline of 29.3% from $119.43 per barrel level that was touched on March 9th. Yesterday, US WTI plunged nearly 18%.
Brent Crude Oil Price: Brent crude has nosedived by nearly 26.2% and touched an intraday low of $88.10 per barrel. This is compared to $119.50 per barrel mark it hit on March 9. Yesterday, the price dropped nearly 9%.
The first link above is worried that the market "is pricing a legacy framework in which these events are temporary, resolvable, and mean-reverting." Indeed, that's what it seems to be doing, and it's trusting Trump on top of it. My guess is that it's probably right.By the way, I hope things turn out OK for Mark Halperin. He works for Megyn Kelly in his 2WAY podcasts, and he's becoming increasingly pro-Trump, as the video embedded above suggests. Meanwhile, Megyn "Me Again" Kelly is reverting to her never-Trump roots.
I sure hope Mark Halperin comes through this in good shape, he's worked extremely hard to restore his career.Flashback to big shot "conservative" Megyn Kelly celebrating "trans kids."@megynkelly is for sale to the highest bidder. She has ZERO integrity. 🤡 pic.twitter.com/pwgqUEtXy2
