The global energy market is currently wrestling with a geopolitical proposition that sounds more like a real estate merger than a military doctrine. Donald Trump has signaled a radical shift in American foreign policy by suggesting that the United States could "jointly" control the Strait of Hormuz alongside a future Iranian administration. This isn't just a casual remark about maritime security. It is a fundamental challenge to the way the world moves oil.
The Strait of Hormuz is the most critical chokepoint on the planet. Roughly 21 million barrels of oil pass through this narrow strip of water every single day. That is about 20% of the world's total consumption. To suggest "joint control" with a regime—even a hypothetical one—upends decades of U.S. policy built on containment and naval dominance. It assumes that the geopolitical tensions of the Middle East can be solved through a bilateral partnership rather than the traditional balance of power.
The Mechanics of a Global Chokepoint
To understand why joint control is such a jarring concept, you have to look at the geography. The Strait is only 21 miles wide at its narrowest point. The shipping lanes are even tighter. They consist of two-mile-wide channels for inbound and outbound traffic, separated by a two-mile buffer zone. Most of these lanes fall within the territorial waters of Iran and Oman.
For decades, the U.S. Fifth Fleet has acted as the de facto guarantor of "freedom of navigation." This is an expensive, high-stakes game of chicken. The U.S. argues it is protecting international trade. Iran argues the U.S. presence is a provocation in its backyard. The suggestion that these two forces could work in tandem implies a level of trust that has not existed since 1979. It also assumes that the "next Ayatollah" or a successor regime would be willing to trade its primary leverage for a seat at the table with Washington.
The Economic Reality of Co-Management
Oil markets hate uncertainty. They also hate complexity. The idea of joint management introduces a layer of bureaucratic and military coordination that is unprecedented. If the U.S. and Iran were to "jointly" control the route, who decides the rules of engagement? Who handles the insurance premiums for the tankers?
Currently, the threat of a closure in the Strait can spike Brent crude prices by $10 or $20 in a matter of hours. This "risk premium" is baked into every gallon of gas you buy. A joint control agreement would, in theory, eliminate that premium. However, the logistical reality is far more difficult. Control of the Strait isn't just about ships. It involves coastal missile batteries, mine-laying capabilities, and sophisticated radar networks. Sharing that infrastructure with a foreign power requires a degree of transparency that usually only exists between the closest of allies, like the U.S. and the UK.
The Problem with the Next Regime Strategy
The core of this proposal relies on a "new regime" in Tehran. This is a gamble on a variable that the U.S. cannot control. History is littered with the remains of foreign policies based on the hope of a friendlier government taking over a hostile nation.
If the U.S. waits for a "new" Iran to secure the Strait, it leaves the current energy supply vulnerable in the interim. Furthermore, any Iranian leader who agrees to hand over a portion of their sovereignty to the U.S. military would likely face immense domestic backlash. The Strait of Hormuz is not just a trade route to Iran; it is their greatest strategic asset. It is the "kill switch" they hold over the global economy. Giving up half of that switch is a hard sell for any nationalist leader, regardless of their religious or political leanings.
The Role of Regional Players
Saudi Arabia and the United Arab Emirates cannot be ignored in this equation. These nations are the primary exporters using the Strait. If the U.S. pivots to a "joint control" model with Iran, it risks alienating the Gulf partners who have relied on the U.S. as a shield against Iranian influence.
The UAE, in particular, has spent billions developing pipelines like the Habshan–Fujairah line to bypass the Strait entirely. They are moving toward a future where the Strait matters less. If the U.S. moves toward a future where they share the Strait with Iran, the traditional alliances in the region will undergo a violent realignment. We are talking about a total shift in the security architecture of the Middle East.
Beyond the Rhetoric of Control
We have to look at what "control" actually means in 2026. It is no longer just about destroyers and aircraft carriers. The rise of low-cost drone swarms and autonomous sea mines has changed the cost-benefit analysis of maritime blockades. A small, motivated force can harass a multi-billion dollar tanker with equipment that costs less than a used car.
Joint control would require a shared technological framework to counter these "asymmetric" threats. If the U.S. and a new Iranian regime aren't sharing intelligence and technology, the "joint" part of the agreement is nothing more than a press release. You cannot manage a chokepoint with two different sets of eyes looking for two different types of enemies.
The Ghost of the 1950s
There is a historical echo here. In the mid-20th century, the British and the Americans tried to manage Iranian resources through various "joint" arrangements and consortia. It ended in the 1953 coup and decades of resentment. The Iranian political psyche is deeply sensitive to the idea of foreign powers managing their geography.
Any proposal that involves a Western power "controlling" an Iranian waterway—even jointly—will be viewed through the lens of neo-colonialism. To make this work, the U.S. would have to offer something so substantial that it outweighs the loss of national pride. That usually means a total lifting of sanctions and a guaranteed share of global energy profits. It is a high price for a promise of security.
The Physical Constraints of the Strait
The Strait of Hormuz is not a deep, wide-open ocean. It is a shallow, cramped corridor.
- Depth: Much of the Strait is less than 100 meters deep.
- Mines: The shallow water makes it an ideal environment for sea mines.
- Speed: Large tankers cannot maneuver quickly. They are sitting ducks.
If "joint control" fails, the resulting wreckage in those narrow lanes could physically block traffic for weeks. The environmental catastrophe of a single supertanker sinking in the Strait would be enough to shut down regional desalination plants, cutting off the water supply for millions in the Gulf. The stakes are not just economic; they are existential for the people living on those shores.
The Alternative to the Joint Model
Instead of joint control, many analysts argue for a multilateral approach. This would involve a coalition of all nations that rely on the oil—including China, India, and Japan—taking responsibility for the Strait. China is currently the largest buyer of Iranian oil. They have more skin in the game than almost anyone else.
If the U.S. tries to go it alone with a "joint" deal with Iran, they are excluding the very customers who keep the oil flowing. A bilateral deal between Washington and Tehran ignores the reality of a multipolar world. China has already brokered diplomatic deals between Iran and Saudi Arabia. They are unlikely to sit back and let the U.S. dictate the terms of the most important oil route in Asia.
The Fragility of the Narrative
The idea that the U.S. could simply negotiate a new reality for the Strait of Hormuz assumes that the U.S. still holds all the cards. But the energy landscape is shifting. The U.S. is now a net exporter of oil. While a spike in global prices still hurts the American consumer, the U.S. is no longer as physically dependent on Hormuz as it was in the 1970s.
This gives Washington more leverage to walk away, but it also makes the "joint control" offer look less like a necessity and more like a tactical maneuver. If the goal is truly to stabilize the market, the solution likely won't be found in a shared naval command. It will be found in the diversification of energy routes and the gradual reduction of the Strait's relevance. Until then, the Strait remains a loaded gun pointed at the heart of the global economy.
Any leader claiming they can hold that gun "jointly" with their adversary is either a visionary or is fundamentally miscalculating the nature of power. Control isn't shared in the Strait of Hormuz; it is contested. Every day the tankers move is a day that the contest has been temporarily settled.
Check the current positioning of the Fifth Fleet against the latest Iranian naval exercises. It tells a much more honest story than any diplomatic overture.
