Hormuz: Mines, Strategy or Business?

By Ismail Al Sharif
The US thought that assassinating senior Iranian leaders would bring down the regime, but this did not happen.
Iran’s inability to match American military and technological superiority led it to adopt a number of strategies, most notably what is known in the military literature as the Mosaic Defense Doctrine. This doctrine is based on dismantling its military central command into small, independent units, each operating autonomously and making its own decisions without consulting the higher command.
From Day 1 of the war, Iran adopted this approach. However, the lack of coordination and the disintegration of the military hierarchy led to chaos and confusion which affected the management of its operations. The situation became contradictory; the politicians were declaring one thing and military commanders acting in a completely different manner and direction.
This was reflected on the ground through extremely dangerous behavior. Military units, using small boats, indiscriminately laid naval mines to deter enemy ships. However, the lack of coordination here backfired resulting in the Iranian navy officers losing their ability to pinpoint the coordinates of the mines they planted in the Hormuz Strait with no accurate maps or reliable records. Some of these mines may have been completely displaced by the currents of the sea. This was further complicated by the fact that these mines were not primitive but far from it; they were sophisticated and able to detect sound and pressure, and thus able to track the passage of large ships and submarines, and detonate automatically upon approach.
However, mine removal is not easy task, as history shows. Even today, news reports continue to surface of mines in various parts of the Kingdom, half a century after the last war. Indeed, mines from World War II are still being discovered on land and at sea.
Even with Britain’s pledge to remove mines after the war, and despite possessing the latest specialized technologies in this field, the task remains arduous, protracted, and uncertain. The specter of a sudden explosion looms, reminding us that the danger of mines is not easily eliminated.
But the decisive factor in weakening navigation in the Hormuz Strait is not primarily military, but rather material. Commercial ships are massive investments, with some vessels valued at around $150 million and their cargoes potentially worth hundreds of millions of dollars. Therefore, a single mine explosion can cause catastrophic losses to both the ship and its cargo. Consequently, no ship sails without insurance; ports, banks, and shipping companies refuse to deal with uninsured vessels, and without insurance, global shipping grinds to a halt.
Herein lies the real surprise: the fate of the Strait is no longer dependent on Iran’s pronouncements regarding its opening or closure, but has effectively fallen into the hands of insurance companies. With the escalating risks, insurance costs have skyrocketed; “war risk” premiums have jumped from approximately 0.25% of the ship’s value to nearly 1% or more, exceeding a massive $1 million per voyage. And it doesnt stop there; seven major insurance companies announced their complete withdrawal, issuing notices of coverage cancellation just within just 72 hours.
And here comes the decisive turning point: Once the insurance coverage is lost, maritime traffic ground to a halt. During this 39-war, ships have effectively ceased sailing with the number of vessels transiting the Strait plummeting by more than 80%. Around 150 oil tankers remain anchored offshore, and major shipping companies suspended their operations, as if this vital artery of global trade had been frozen by a financial, rather than a military decision.
The US government attempted to provide alternative insurance coverage, but this effort failed and US President Trump’s pronouncements regarding mine removal were inconsistent with the reality.
The issue of reopening the Strait has once again become a prominent topic, but the deeper truth is that its fate is no longer determined by political statements or military actions, but rather by the decisions of insurance experts. Even if the war were to end immediately, ships would not resume sailing right away. Insurance companies need time to reassess the level of risk, and they base their decisions not on political logic, but on cold, hard numbers and rigorous data.
