The Strait of Hormuz — the narrow waterway through which roughly one-fifth of the world's oil supply flows — remains largely abandoned despite a ceasefire agreement between the United States and Iran, according to new analysis from BBC Verify.

Satellite tracking and maritime data show that only a handful of commercial vessels have attempted the crossing since the truce took effect, a stark indication that shipping companies remain unconvinced of the route's safety. The continued disruption threatens to sustain elevated energy prices and supply chain complications that have rippled across global markets.

A Chokepoint Under Threat

The Strait of Hormuz, just 21 miles wide at its narrowest point, connects the Persian Gulf with the Gulf of Oman and the Arabian Sea beyond. On a typical day before recent hostilities, hundreds of vessels would transit the waterway, carrying crude oil, liquefied natural gas, and containerized goods.

The strategic importance of this passage cannot be overstated. According to the U.S. Energy Information Administration, approximately 21 million barrels of oil pass through the strait daily — representing about 21% of global petroleum liquids consumption. Any sustained closure or reduction in traffic has immediate implications for energy markets worldwide.

Iran has long viewed control over the strait as a strategic lever, occasionally threatening to close the waterway during periods of heightened tension with Western powers. The recent escalation that preceded the ceasefire saw those threats materialize into action, with maritime security incidents forcing most commercial operators to suspend transits.

Ceasefire Fails to Restore Confidence

While the ceasefire agreement halted direct military confrontation, it has not provided the security guarantees that shipping companies require before resuming normal operations. Industry sources indicate that insurers have maintained elevated risk premiums for vessels attempting the crossing, making many routes economically unviable even if technically accessible.

The reluctance to return reflects lessons learned from previous episodes of regional instability. During the 2019 tanker attacks attributed to Iran, shipping companies faced not only physical risks but also complex insurance claims, detained crews, and damaged vessels. The institutional memory of those incidents continues to shape current decision-making.

Maritime security analysts note that a formal ceasefire between state actors does not automatically translate to safe passage for commercial vessels. Without robust enforcement mechanisms, international naval escorts, or explicit Iranian guarantees, shipping companies are opting for longer, more expensive alternative routes around the Arabian Peninsula.

Economic Consequences Mount

The diversion of shipping traffic has created a cascade of economic effects. Oil prices, while stabilizing somewhat after the ceasefire announcement, remain elevated compared to pre-crisis levels. European and Asian refineries that typically source crude from Persian Gulf producers have been forced to seek alternative suppliers or draw down strategic reserves.

Beyond energy markets, the disruption affects container shipping and the movement of manufactured goods. Several major shipping lines have rerouted vessels around the Cape of Good Hope — adding approximately 3,500 nautical miles and ten days to journey times between Asia and Europe. These delays compound existing supply chain pressures and contribute to inflationary pressures in consumer goods.

The prolonged uncertainty also affects regional economies heavily dependent on maritime trade. Gulf Cooperation Council states, whose economic models rely on hydrocarbon exports and trans-shipment trade, face revenue pressures if normal traffic patterns do not resume soon.

What Comes Next

Maritime industry observers suggest that restoring confidence will require more than the absence of conflict. Specific measures under discussion include international naval patrols to guarantee safe passage, formal agreements on rules of engagement in the strait, and potentially a UN-backed maritime security framework.

Some shipping executives have privately indicated they are awaiting a sustained period — perhaps 30 to 60 days — of incident-free transits before committing to resume regular operations. Others have suggested that insurance underwriters, rather than political agreements, will ultimately determine when the route becomes commercially viable again.

The situation also highlights the broader fragility of global shipping chokepoints. Similar concerns apply to the Suez Canal, the Strait of Malacca, and other narrow passages where geopolitical tensions intersect with critical trade routes. The Hormuz situation may accelerate discussions about supply chain resilience and the strategic risks of concentrated maritime dependencies.

For now, the world's most important oil transit route remains quiet — a testament to how quickly geopolitical instability can disrupt the physical infrastructure of global commerce, and how slowly confidence returns even after formal hostilities cease.
