Iran doesn't need a naval blockade to close the Strait of Hormuz. The mere threat of drone and missile attacks is enough to deter shippers and insurers, creating a "de facto closure." This asymmetrical strategy highlights how psychological warfare can be as effective as direct military action in disrupting global trade.

The disruption in the Strait of Hormuz isn't a formal closure. Instead, shippers and producers are adopting a "wait and see" approach, halting flows due to reports of damaged ships and skyrocketing insurance premiums, effectively creating a self-imposed blockade.
By attacking just a few ships, Iran creates enough perceived risk to make insurance carriers unwilling to cover vessels transiting the Strait of Hormuz. This effectively disrupts 20% of the world's oil supply without needing a large-scale military blockade, a key tactic in asymmetric economic warfare.
The war in Iran is choking the Strait of Hormuz, which handles 20% of global oil. This disruption impacts nearly three times more oil volume than Russia's exports at the start of the Ukraine war, posing a significantly larger threat to the global economy and inflation.
Major container lines will divert entire fleets on longer, more expensive routes around continents based solely on the threat of attack, as seen with the Houthis in the Red Sea. The perception of risk, not just the occurrence of incidents, is a primary driver of costly, system-wide disruptions in logistics.
Dr. Anas Al-Hajji asserts that Iran did not militarily close the Strait of Hormuz. The disruption was caused by European insurance companies canceling policies for tankers under EU solvency rules after an attack near Sri Lanka expanded the perceived risk zone, making transit impossible for uninsured ships.
The Middle East conflict has moved beyond risk to a physical blockade of the Strait of Hormuz. With commercial tankers no longer transiting, nearly 20% of global oil is cut off from markets. This supply disruption, not just a risk premium, is driving oil prices toward $100/barrel.
Iran effectively weaponized the Strait of Hormuz not with mines, but by creating enough uncertainty to make UK-based insurance companies pull out. This demonstrates how financial systems can be leveraged as powerful geopolitical choke points.
The conflict's primary impact on oil is not that supply is offline, but that its transport through the Strait of Hormuz is blocked. This distinction is key to understanding price scenarios, as supply exists but cannot be delivered.
A militarily weaker nation can effectively counter a superpower by creating targeted fear and risk in a vital economic channel, like a shipping strait. By making insurance prohibitively expensive and transit dangerous, they can achieve strategic goals without needing to win a conventional military engagement.
Iran employs inexpensive weapons against shipping in the Strait of Hormuz. This asymmetric strategy avoids direct military confrontation while making the risk too high for insured commercial vessels, effectively closing the strait without a formal blockade.
