Strait of Hormuz Reopens Under New Risks: Mines and Dual Transit Regime Reshape Passage

## Strait of Hormuz Reopens, But Navigational Risks Persist The Strait of Hormuz is once again open to commercial traffic, yet the waterway that vessels are returning to bears little resemblance to the one that existed prior to the recent conflict, according to reporting by gCaptain. Shipping companies are navigating a significantly more complex and hazardous environment as they resume transits through one of the world's most strategically critical chokepoints. Approximately 20 percent of global oil supply passes through the Strait of Hormuz, making its operational status a matter of acute concern for energy markets, tanker operators, and maritime insurers worldwide. Any sustained disruption to traffic flow carries immediate consequences for global crude and LNG pricing. ### Mine Threat Remains Unresolved Among the most pressing concerns for mariners is the presence of mines in and around the strait. Unlike surface threats that can be visually identified and avoided, mines present a persistent, covert danger that does not dissipate simply because hostilities have ceased. Mine-clearance operations are typically slow, resource-intensive, and require coordinated multinational naval efforts — a process that could take weeks or months to complete to a standard that satisfies commercial operators and their insurers. Until credible mine-clearance certification is issued by relevant naval authorities, ship operators and their protection and indemnity (P&I) clubs are likely to demand enhanced war risk premiums for transits, adding material cost to voyages through the region. ### Dual Transit Regime Adds Operational Complexity Beyond the physical hazards, gCaptain reports that a dual transit regime is now in effect, introducing a layer of procedural and jurisdictional complexity that did not previously exist. The precise nature of this arrangement — including which authorities are asserting oversight, what documentation or notifications are required, and how compliance will be enforced — will be critical information for fleet operators and port agents managing voyages in the Persian Gulf. A dual regime of this nature can create ambiguity over right-of-passage protocols, vessel reporting requirements, and the risk of detention or interference, all of which factor into voyage planning and risk assessments. ### Industry Implications For tanker owners, LNG carriers, and bulk operators with regular Persian Gulf rotations, the reopening of the strait is a necessary but insufficient condition for a return to normal operations. Risk managers will need current intelligence on mine-clearance progress, clarity on the transit regime's requirements, and updated guidance from flag states and classification societies before routing vessels through the strait without elevated precautions. The situation underscores the broader vulnerability of global energy supply chains to geopolitical disruption at key maritime chokepoints, and is likely to sustain elevated war risk insurance premiums in the region for the foreseeable future. *Source: gCaptain*
