The headlines are feeding you a fairy tale about a bottleneck. They want you to believe that the Strait of Hormuz is a binary switch—either open or closed—and that Tehran is currently hand-picking a few "favored" vessels to pass through like a bouncer at an exclusive club.
It’s a seductive narrative. It paints a picture of total Iranian dominance and Western helplessness. It also happens to be a fundamental misunderstanding of how maritime insurance, shadow fleets, and global energy arbitrage actually function.
The "handful of favored ships" trope isn't just lazy journalism. It’s a distraction from the reality that the Strait remains a high-volume corridor for anyone willing to pay the "risk premium" or hide behind a sovereign guarantee. Iran isn't closing the door; they are just changing the price of admission and the currency of the bribe.
The Myth of Selective Transit
Mainstream analysis suggests Iran is "allowing" specific ships through as a show of geopolitical strength. This assumes Tehran has a granular, real-time veto over every hull that enters the 21-mile-wide chokepoint.
They don't.
What they have is a PR machine and a fleet of fast boats. If you look at the actual AIS (Automatic Identification System) data, the "favored" ships aren't just lucky winners of a Persian lottery. They are vessels that fall into three specific, cold-blooded categories:
- The Sovereignty Shields: Ships carrying cargo for nations Iran cannot afford to alienate—namely China and, to a lesser extent, India.
- The Ghost Riders: The "Shadow Fleet" of aging tankers with opaque ownership and questionable insurance that have been circumventing sanctions for years.
- The High-Stakes Gamblers: Commercial vessels whose owners have calculated that the $30,000-per-day war risk surcharge is cheaper than the $1 million fuel bill for a detour around the Cape of Good Hope.
Iran isn't "favoring" these ships. Iran is ignoring them because attacking them would either cause a diplomatic suicide note (China) or yield zero leverage (the shadow fleet).
Why the "Blockade" is a Business Model
Stop thinking of the Strait of Hormuz as a military front. Start thinking of it as a toll booth.
When the media reports that Iran is harassing tankers, the immediate reaction is "supply chain crisis." But look at the numbers. Global oil prices rarely spike for more than 48 hours after a Hormuz "incident." Why? Because the market knows the difference between a skirmish and a shutdown.
Iran's goal isn't to stop the flow of oil. Their economy—suffocated by sanctions—still relies on the illicit export of their own crude. You don't burn down the only bridge you use to smuggle your goods to market. Instead, you create enough friction to keep insurance premiums high for your enemies while providing "safe" passage for your proxies.
I’ve watched shipping desks in Singapore and Dubai navigate these waters for two decades. The "favored" status isn't granted by a handshake in Tehran; it's earned through "flagging out" to registries that Iran views as neutral or through the use of non-Western P&I (Protection and Indemnity) clubs.
The Logistics of the Lie
The narrative that Iran is manually selecting ships ignores the sheer physics of the Strait.
- Daily Volume: Roughly 20.5 million barrels of oil pass through daily.
- The Traffic Separation Scheme (TSS): Ships follow strict inbound and outbound lanes.
- The Deep Water Requirement: Loaded VLCCs (Very Large Crude Carriers) can't just swerve into Omani or Iranian territorial waters to avoid a patrol boat.
If Iran truly wanted to "favor" a handful of ships, they would have to physically board and inspect every vessel. They don't have the manpower or the naval assets to do that without triggering a massive, kinetic response from the U.S. Fifth Fleet.
Instead, they use Kinetic Signaling. They seize one ship—usually a mid-sized tanker with a weak legal defense or a murky ownership trail—and let the fear do the rest of the work. It’s a psychological blockade, not a physical one.
Misunderstanding the "Shadow Fleet"
The biggest gap in the competitor’s "favored ship" theory is the failure to recognize the rise of the gray market.
We are currently seeing a massive bifurcation in global shipping. There is the "White Fleet"—compliant, insured by the International Group of P&I Clubs, and flying respectable flags. Then there is the "Shadow Fleet"—vessels often over 20 years old, using "dark" ship-to-ship transfers, and insured by sovereign Russian or Chinese entities.
Iran doesn't "allow" the shadow fleet through; the shadow fleet is the system. These ships are invisible to the sanctions-heavy frameworks that Western journalists use to measure trade. When you see a report saying only a "handful" of ships are passing, it usually means only a handful of compliant, Western-tracked ships are passing.
The ghosts are moving just fine.
The Fallacy of the "Closing the Strait" Threat
Every few months, a general in the IRGC (Islamic Revolutionary Guard Corps) threatens to "close the Strait." The West panics. The price of Brent jumps $2.
It is the most successful bluff in modern history.
Closing the Strait would require Iran to mine the waters. Mining the waters is an act of war that would result in the immediate destruction of the Iranian Navy and their primary oil terminals at Kharg Island. More importantly, it would alienate China—Iran’s only major customer.
Iran is not a suicidal state. It is a cynical one.
The "favored ships" narrative plays right into their hands. It makes them look like the masters of the waterway when, in reality, they are just the noisiest neighbors. They aren't controlling the flow; they are taxing the nerves of the global shipping industry.
The Reality of War Risk Insurance
If you want to know who is "favored" in the Strait, don't look at the flags. Look at the insurance premiums.
- Standard Hull & Machinery (H&M): Covers the ship.
- War Risk Insurance: A separate "add-on" required for high-risk zones.
In 2019, after the Limpet mine attacks, war risk premiums for the Persian Gulf jumped from 0.02% to 0.5% of a vessel's value. For a $100 million tanker, that’s an extra $500,000 per voyage.
The ships that aren't passing through aren't being "blocked" by Iran. They are being blocked by their own accountants. Many Western shipowners have simply decided the ROI isn't there. This isn't Iranian dominance; it's Western risk-aversion.
Dismantling the "People Also Ask" Nonsense
Is the Strait of Hormuz closed?
No. It’s just expensive. If you have the stomach for a 500% spike in insurance and a flag that doesn't say "USA" or "UK," you can sail through right now.
How does Iran pick which ships to seize?
They don't pick based on cargo; they pick based on vulnerability. They look for ships with "clean" legal records where a seizure can be framed as a "legal dispute" over a previous collision or debt. It’s lawfare backed by machine guns.
Why doesn't the U.S. Navy escort every ship?
Because there are too many ships and not enough destroyers. More importantly, an escort doesn't stop an insurance company from raising rates. The Navy can protect you from a missile; they can't protect your balance sheet from a spreadsheet.
The Brutal Truth for Investors
If you are betting on a total shutdown of the Strait, you are going to lose money.
The "favored ship" scenario is actually the most stable state for Iran. It allows them to maintain a "perpetual simmer." A total closure is a "boil over" that ends with them losing everything. By selectively harassing vessels, they keep the world on edge, keep oil prices from bottoming out, and maintain their relevance without actually having to fight a war they would lose in 72 hours.
The real story isn't that Iran is picking winners. The story is that the West has allowed a mid-tier regional power to dictate the psychological terms of global trade because we are too afraid of a $5-per-gallon gas price to call their bluff.
Stop looking for "favored" ships. Start looking for the ships that don't care about the rules. That’s where the real power lies.
The Actionable Reality
If you are an operator in this space, your move isn't to wait for "favored" status. It’s to diversify your insurance stack and decouple your fleet from Western-centric P&I clubs if you want to maintain liquidity in the Gulf.
The Strait of Hormuz is not a gate; it's a filter. It filters out the timid, the over-leveraged, and the politically exposed.
The ships passing through today aren't "favored" by Iran. They are simply the ones that realize that in a world of declining American maritime hegemony, "legal" is a relative term and "insured" is a matter of who owns the bank.
The Strait is open for business. You just have to be comfortable doing business in the dark.
Don't wait for a permission slip from Tehran that isn't coming. Recognize the bluff, calculate the risk premium, and stop pretending that a few fast boats in the Gulf of Oman have rewritten the laws of global commerce. They haven't. They’ve just made the truth more expensive to see.
