The World's Most Dangerous Chokepoint
The Strait of Hormuz is narrow, shallow, and irreplaceable. Roughly 20% of the world's oil supply passes through this waterway, which at its narrowest point is barely 30 miles wide, with shipping lanes that compress traffic into corridors just a few miles across. It has always been a vulnerability in the global energy system. Since late February 2026, that vulnerability has been violently exploited.
Iran's Operation Epic Fury has effectively closed the strait to Western-flagged commercial shipping. Traffic through the waterway has dropped by approximately 90%. Oil prices have surged past $108 per barrel, with spikes reaching $126. Twenty-eight ships have been attacked. Twelve seafarers are dead or missing. The global economy is feeling the squeeze.
Iran's Calculated Strategy
What makes this crisis particularly sophisticated is Tehran's approach. Iran has not imposed a blanket blockade — that would be an unambiguous act of war inviting an overwhelming military response. Instead, it has implemented a selective closure. Vessels flagged to China, Russia, and India are permitted to transit, reportedly for a fee of approximately $2 million per passage. Western-flagged shipping is blocked entirely.
This selectivity is strategically elegant. It creates a wedge between the Western alliance and nations that depend on Iranian cooperation for energy security. China and India — both major oil importers — have an economic incentive to avoid joining any coalition against Tehran. Russia, already aligned with Iran through shared strategic interests, benefits from the disruption to Western energy supply and the resulting price surge.
The result is that the diplomatic isolation of Iran, which would normally follow an act of maritime aggression on this scale, has been significantly harder to achieve. Tehran has weaponised the global economy's dependencies with considerable skill.
The Human Cost
Behind the geopolitical manoeuvring, the human dimension should not be overlooked. Merchant seafarers — civilians working in one of the world's most essential but least visible industries — are bearing the brunt of this crisis. The attacks on commercial vessels have killed and injured crew members who have no part in the strategic calculations of either side. The maritime insurance market has responded predictably: premiums for Gulf transit have become prohibitive for many operators, which has its own cascading economic effects.
The Convoy Escorts
The response from Western navies has been to revert to a model of maritime operations not seen at this scale since the Tanker War of the 1980s. US, British, and allied naval forces are now conducting convoy escort operations through the strait, shepherding groups of commercial vessels through the most dangerous stretches under armed protection.
The operational complexity is enormous. Coordinating multinational naval assets to provide continuous coverage requires meticulous planning, robust communications, and the kind of interoperability that only comes from decades of allied training and operations. The Royal Navy, operating alongside the US Navy and other partners, is drawing on escort experience that traces back through centuries of maritime history — though the threat environment has evolved considerably since the last time convoys were a routine feature of naval operations.
The Threat Environment
The escort forces face a multi-layered threat. Iran's military options in the strait include fast attack craft armed with anti-ship missiles, shore-based anti-ship missile batteries, sea mines, midget submarines, and the ever-present possibility of unmanned systems. The confined waters of the strait favour the defender — there is limited room for manoeuvre, and the geography provides natural concealment for shore-based assets.
The mine threat is particularly concerning. Naval mine clearance is slow, dangerous, and resource-intensive. A single mining operation could close a shipping lane for days while clearance forces work methodically to reopen it. Iran learned the value of mines during the Tanker War and has invested in its mine warfare capability since.
The Economic Pressure
The longer the strait remains effectively closed, the greater the economic pressure on all parties. European economies are particularly exposed. But the pressure cuts both ways — Iran's own economy, weakened by years of sanctions, relies on oil revenue that a prolonged closure disrupts.
What Happens Next
The strategic question is whether this crisis resolves through diplomacy or escalation. The historical precedent of the 1980s Tanker War suggests that both are possible — that conflict dragged on for years, with periodic escalation, before eventually subsiding without a decisive military resolution.
The current situation is arguably more dangerous. The weapons are more capable, the economic stakes are higher, and the broader geopolitical context — with active US military operations against Iran elsewhere — provides multiple escalation pathways.
What is clear is that the Strait of Hormuz has once again demonstrated its status as the single most consequential chokepoint in global maritime security. The nations that depend on it for energy supply have been reminded, in the most direct way possible, of the cost of that dependency.
