Hormuz Owners Face 13-Transit Reality After Strikes Freeze IMO Corridor

Shipowners with VLCCs and Suezmaxes committed to Gulf loadings confront an immediate routing decision after two kinetic strikes in 72 hours and the abrupt suspension of the IMO evacuation corridor left the Strait of Hormuz open in name only, with daily transits stuck at roughly 13 vessels.

The 13-Transit Bottleneck

Pre-war traffic through the strait routinely exceeded 120 vessels per day. The current average of 13 represents a 90 percent collapse that has concentrated remaining movements into narrow, high-risk windows. Owners report that even those few transits now require extended waiting periods outside the strait while operators assess fresh strike patterns. The resulting queue has already added two to four days of demurrage exposure on several fixtures concluded before the latest incidents.

Evacuation Corridor Suspended Indefinitely

The IMO-managed safe passage lane, established to allow commercial traffic during earlier phases of regional tension, has been placed on hold without a published resumption date. Masters who had relied on the corridor for coordinated naval escort now face the choice of proceeding unescorted or anchoring outside the area. Several operators have already instructed vessels to divert south, accepting the 12-to-18-day Cape routing penalty rather than test the corridor’s status.

War-Risk Markets Price the New Normal

Hull and P&I underwriters have begun quoting additional premiums of 0.75 to 1.25 percent of hull value for Hormuz transits, levels not seen since the 2019 tanker incidents. For a modern VLCC valued at $110 million, that equates to an extra $825,000–$1.375 million per voyage. Charterers absorbing these costs on spot cargoes are already shifting clauses to place the burden on owners, prompting several Greek and Norwegian managers to declare the strait off-limits until further notice.

Manning Agencies Confront Crew Refusals

Seafarer unions and manning agencies report a sharp rise in refusals for Gulf rotations. Filipino and Indian officers, who crew the majority of tonnage transiting Hormuz, have cited the suspended corridor and recent strikes as justification for declining assignments. Owners facing crew shortages are offering hazard bonuses of up to 150 percent, yet some vessels remain anchored outside the strait awaiting replacement teams willing to proceed.

Alternative Routing and Freight Market Shifts

With Hormuz effectively throttled, charterers have accelerated fixtures for West African and Brazilian crude into Asia, pushing Cape voyage rates for VLCCs up 35 percent week-on-week. The longer hauls also tighten tonnage availability in the Atlantic basin, lifting TCE earnings for owners willing to accept the extended itinerary. Energy traders are meanwhile booking additional storage at Singapore and Fujairah to buffer against further supply disruptions.

What to Watch Next

Monitor any IMO or coalition statement that sets a firm resumption date for the evacuation corridor; a confirmed restart within seven days would likely trigger a modest rebound in daily transits, while continued silence will cement the Cape diversion as the default routing for the balance of the summer.
