Commercial shipping through the Strait of Hormuz has slowed significantly following the resumption of US strikes against Iran. While the United States maintains the waterway remains open to international transit, Tehran has declared the strait closed to any vessels lacking express permission.

The collapse of shipping traffic following US strikes on Tehran

The Strait of Hormuz is facing a period of unprecedented maritime instability. Following the resumption of US strikes against Iran two weeks ago, commercial traffic through the vital oil chokepoint has plummeted to levels not seen during the height of previous conflicts. This sudden downturn follows a breakdown in the US-Iran ceasefire, during which Iran launched strikes against three separate vessels. In response, President Trump authorized the restart of strikes on Tehran, a move that has fundamentally altered the risk profile for global energy transit.

While the United States maintains that the strait remains open to international transit—except for ships sailing to or from Iranian ports—the reality on the water suggests a much more fractured environment. The tension between these two opposing legal stances has created a vacuum of certainty for the global shipping industry.

A potential windfall of hundreds of millions for the Iranian regime

The Iranian regime may be positioned to reap significant financial rewards from the current maritime chaos.. As reported by the source, there is growing speculation that Tehran could be collecting fees from ships seeking safe passage through the waterway. If these "protection" fees are being levied , even on a limited basis, the regime could be generating tens to hundreds of millions of dollars.

This potential windfall allows Iran to maintain intense pressure on one of the world's most critical maritime corridors while simultaneously funding its own strategic interests. This shift is evidenced by unusual traffic patterns, with some vessels appearing to sail closer to the Iranian side of the narrow waterway to navigate the heightened tension and seek perceived safety.

Marco Rubio’s warning on the dangerous precedent of Iranian maritime control

Senator Marco Rubio has signaled deep concern regarding the long-term strategic implications of this maritime standoff. According to the report, Rubio warned this week that allowing Tehran to dictate access through the Strait of Hormuz would create a "dangerous precedent." The issue extends beyond immediate economic loss; the very nature of international shipping is shifting.

The global shipping industry is increasingly being forced to account for Iranian wishes and regional volatility when deciding how to navigate the narrow waterway, effectively granting Tehran a degree of de facto control. This psychological shift suggests that even without direct physical blockades, Iran is successfully influencing the movement of global commerce by simply making its presence a mandatory variable in maritime planning.

The mystery of the disappearing AIS transponders

The widespread disabling of Automatic Identification System (AIS) transponders is creating a massive data gap in global shipping intelligence. Many vessels are now turning off their tracking systems before entering the danger zone,making it nearly impossible to verify the true volume of trade passing through the strait.. This lack of transparency leaves several critical questions unanswered: Is Tehran actively profiting from these ships through undisclosed fees? How much legitimate commerce is actually being diverted or suppressed?

Furthermore, the situation highlights a legal limitation for the US Navy, which generally cannot stop or board foreign merchant vessels simply because they are sailing near Iran or choosing a particular route. Unless a ship is violating specific US sanctions or transporting prohibited cargo, the Navy lacks the immediate legal grounds for interdiction, leaving a gap in the enforcement of open maritime corridors.
