Strait of Hormuz Crisis 2026: What It Means for Your Cargo Insurance

In early 2026, the Strait of Hormuz became a live conflict zone. Military action, vessel seizures, and the threat of further escalation have disrupted one of the world's most critical shipping chokepoints, through which roughly 20% of the world's oil and significant volumes of containerised trade pass daily.

For cargo owners, the immediate consequences were swift and severe: war risk cover cancelled with 7 days' notice, premiums for remaining cover surging to multiples of pre-crisis levels, and shipments stranded or rerouted as carriers declined to transit the Strait.

This guide covers what has happened, what it means for your cargo insurance, and what you should be doing right now.

What Has Happened

As of April 2026, the Joint War Committee (JWC) has issued JWLA-033, designating the Persian Gulf, Gulf of Oman, Strait of Hormuz, Red Sea, Gulf of Aden, and parts of the western Indian Ocean as listed areas of elevated war risk. This is one of the broadest JWC designations in recent history.

Military action in and around the Strait has included missile strikes on commercial vessels, drone attacks, vessel seizures by belligerent forces, and naval confrontations. Multiple commercial vessels have been damaged or seized, and several major shipping lines have suspended or rerouted services through the Strait.

The insurance market responded with mass cancellation of war risk cover for the affected areas. Under Lloyd's and London market wordings, cargo war risk can be cancelled with 7 days' notice. Hull war risk can be terminated with 48 hours' notice under automatic termination clauses.

Both provisions were exercised widely.

How the Crisis Affects Your Cargo Insurance

Your standard cargo cover is unchanged but insufficient

Your standard marine cargo insurance under Institute Cargo Clauses (A), (B), or (C) 2009 is not directly affected by the crisis. It continues to cover the standard perils it always covered. But standard cover excludes war under Clause 6, which means the perils that are actually causing losses in the Strait are not covered by your base policy.

Your war risk cover may have been cancelled

If you had Institute War Clauses (Cargo) CL385 attached to your policy, your insurer may have exercised the 7-day cancellation provision for transits through the Gulf. Check with your broker whether your war cover remains in force for the specific corridors you ship through.

Do not assume it does. Policies that covered Gulf transits in January 2026 may no longer cover them in April 2026. Get written confirmation.

War risk premiums have surged

For cargo owners who can still obtain war cover for Gulf transits, the additional premium has increased dramatically. War risk surcharges from carriers have risen in parallel, adding to the total cost of moving goods through the affected area.

The premium increase reflects reduced capacity (fewer underwriters willing to write the risk), elevated loss potential (active military conflict), and uncertainty about escalation.

Rerouting changes your risk profile

Many carriers have rerouted services via the Cape of Good Hope to avoid the Strait of Hormuz and the Red Sea entirely. This adds 7-14 days to transit times for Malaysia-Europe and Malaysia-Middle East routes.

The longer transit means extended exposure to standard perils (weather, handling, theft), potentially higher premiums for the longer voyage, cargo arriving outside shelf-life windows for perishables, and increased working capital tied up in goods in transit.

Specific Impact by Trade Corridor

What Malaysian and Singapore Shippers Should Do Now

Confirm your war cover status. Contact your broker and get written confirmation of whether your Institute War Clauses (Cargo) CL385 remain in force for the specific trade corridors you use. If cancelled, understand what alternatives exist.

Review every pending and planned shipment. For any cargo currently on the water or scheduled to ship through JWC listed areas, confirm that war cover is in place for that specific transit. Cover must be in force at the time of sailing, not just at the time of booking.

Understand the distinction between the surcharge and the insurance. The war risk surcharge on your freight invoice covers the carrier's vessel, not your cargo. You need your own CL385 cover, arranged through your cargo insurer.

Factor rerouting into your insurance. If your carrier is rerouting via the Cape of Good Hope, your transit time and risk profile change. Notify your insurer of the route change.

Your policy should cover the actual route taken, not just the originally planned route.

Discuss force majeure provisions. If you have contracts that require delivery by a specific date and the Hormuz crisis causes delay, check whether your contract includes force majeure provisions. Cargo delay is excluded from standard ICC clauses (Clause 4.5 in ICC (A) 2009), so insurance does not cover the financial consequences of late delivery.

Consider specialist coverage for high-value transits. If you must ship high-value cargo through or near the conflict zone, specialist war risk placement through Lloyd's or the London market may be available at elevated premiums. Your broker needs access to war risk capacity to arrange this.

What Happens If the Crisis Escalates

If the Strait of Hormuz is closed entirely to commercial traffic, the consequences for cargo insurance would include total withdrawal of war risk cover for the Persian Gulf and Gulf of Oman, potential extension of JWC listed areas to cover the wider Indian Ocean, massive rerouting through the Cape of Good Hope becoming the default for all westbound Asian trade, and further premium hardening across the war risk and standard cargo markets.

As of April 2026, the Strait has not been closed to all traffic, but transits are significantly reduced and subject to elevated risk. The situation is evolving, and insurer positions are changing week to week.

Frequently Asked Questions

Is the Strait of Hormuz closed to commercial shipping?

As of April 2026, the Strait is not fully closed, but transits are significantly reduced. Many major carriers have suspended services through the Strait or are transiting with elevated caution. The situation is changing and any assessment of current transit status should be verified against the latest shipping advisories.

Has my war risk cover been cancelled?

Many insurers exercised 7-day cancellation provisions for the Persian Gulf and Gulf of Oman in early 2026. Your specific cover depends on your policy terms and your insurer's position. Contact your broker for written confirmation of your current war cover status for the specific routes you use.

Can I get new war risk cover for Gulf transits?

Capacity exists but is limited and expensive, as of April 2026. Specialist war risk underwriters in the Lloyd's and London market continue to quote, but premiums are at multiples of pre-crisis levels. Access depends on your broker's relationships with war risk capacity providers.

Does rerouting via the Cape of Good Hope affect my cargo insurance?

The route change should be notified to your insurer. A longer transit increases exposure to standard perils and may affect premium. Your warehouse-to-warehouse coverage under Clause 8 of ICC (A) 2009 terminates 60 days after discharge at the final port; the extended transit may bring you closer to this limit.

Are my goods covered if they are stranded at a port because of the crisis?

If your goods have been discharged at an intermediate port and are waiting for onward transit, the 60-day termination provision under the transit clause may apply. Storage beyond this period requires separate arrangement with your insurer. Notify your insurer immediately if your cargo is stranded.

Does the crisis affect my cargo insurance for routes that do not go through the Gulf?

Directly, no. Your standard cargo cover for Pacific, intra-Asian, and trans-Pacific routes is unaffected by the Hormuz crisis. Indirectly, vessel redeployment and port congestion caused by the crisis may affect schedule reliability and increase handling at congested ports, which slightly elevates standard peril exposure.

What is JWLA-033?

JWLA-033 is the Joint War Committee Listed Areas designation, issued in March 2026, that expanded the listed areas to include the Persian Gulf, Gulf of Oman, Red Sea, Gulf of Aden, and parts of the Indian Ocean. Cargo transiting these areas triggers war risk additional premiums.

Voyage Conclusion

The Strait of Hormuz crisis is the most significant disruption to marine cargo insurance markets since the Red Sea crisis began. For Malaysian and Singaporean shippers, the impact is direct: every westbound shipment through the Suez Canal or the Persian Gulf is affected by either cancelled cover, surging premiums, carrier rerouting, or all three.

Voyage arranges marine cargo insurance with war risk and strikes extensions for shippers through affected corridors, with access to war risk capacity in the Lloyd's and London market. If you are shipping through or near the Gulf, Red Sea, or Indian Ocean approaches, talk to us about your war risk position.
