When War-Risk Insurance Becomes a State Backstop: Reading the Hormuz Crisis for Indian Energy and Container Trade

On 28 February 2026, coordinated US and Israeli strikes on Iran were followed within days by Tehran declaring the Strait of Hormuz "closed" and threatening any vessel that attempted the transit. The insurance response was almost instant. Within roughly 48 hours, additional war-risk premiums (AWRP) for tankers crossing the Gulf jumped from around 0.125% of hull value per transit to a peak of 2.5% to 5% in early March. For a very large crude carrier (VLCC), that translated to a single-voyage war premium near USD 5 million. The Lloyd's Joint War Committee widened its listed high-risk area to cover the entire Persian Gulf, and several marine war insurers simply stopped quoting.

This is the part brokers need to internalise: capacity did not run out because reinsurers lacked balance sheet. The Lloyd's Market Association was explicit that reduced vessel traffic was driven by safety, not by insurance availability. Underwriters could price the risk; they could not price a vessel they expected to be hit. Tanker traffic through Hormuz dropped sharply, with over 150 ships reported anchored outside the strait before throughput fell close to zero at the peak. Brent crude spiked toward USD 118 to 120 a barrel.

For an Indian importer of crude or LPG, roughly 40% of national crude arrives via Hormuz, so this was never an abstract Gulf story. It was a direct hit on the cost and insurability of energy cargoes that Indian refiners and gas distributors had treated as routine. The lesson for the placement desk is that war cover in a live chokepoint behaves nothing like the annual open cover most cargo books run on. It is single-voyage, repriced daily, and conditional on movements no insurer controls.

The domestic shock arrived through the reinsurer. GIC Re, India's sole national reinsurer, withdrew marine hull war risk cover across several high-risk regions effective 3 March 2026, and told marine cargo insurers to strip war risk out of their pricing even where they had previously bundled it. That decision matters far more to an Indian broker than any London headline, because most Indian marine cargo treaties cede to GIC Re. When the reinsurer behind the treaty exits a peril, the primary insurer's appetite follows whether or not the underwriter personally wants to keep writing it.

The practical effect on the ground was a sudden gap between what an importer's standing open cover said and what it would actually pay. Standard cargo policies in India incorporate the Institute War Clauses (Cargo), but those clauses contain a Gulf and adjacent-waters framework, automatic termination provisions, and a seven-day cancellation clause on the war and strikes sections. Once GIC Re moved, primary insurers invoked those cancellation rights, and importers found that war cover on goods afloat in or near the Gulf had to be re-bought voyage by voyage, at rates set that week.

This is where broker value showed. The desks that came out ahead were the ones that already knew which of their clients had Gulf exposure, had the open cover wordings on hand, and could move a held-covered or single-voyage war declaration through the insurer the same day a fixture was confirmed. The desks that treated war risk as a line item nobody reads spent March firefighting.

The most structurally interesting development was not the price spike but who stepped in. In early March 2026, the US administration directed the International Development Finance Corporation (DFC) to provide political-risk insurance and guarantees for maritime trade, especially energy, moving through the Gulf. The pledged capacity was reported in the tens of billions of dollars, an order of magnitude larger than any active DFC commitment, and was scaled up further as the crisis deepened. A major US insurer was named lead underwriter, managing pricing, terms, risk assumption, policy issuance and claims, with a panel of large carriers behind it. Coverage began with hull and machinery and cargo, then extended to liability.

Read structurally, this is war-risk cover migrating from the private market to a sovereign reinsurance backstop, the same pattern seen historically with terrorism pools after large losses. The state is acting as reinsurer of last resort so that private insurers can keep issuing policies at a price commerce can bear. The World Economic Forum framed it bluntly as governments becoming the insurer of last resort.

For Indian brokers, three implications follow. First, the DFC facility is largely oriented to US-nexus trade and US insurer paper, so it is not a counter your Indian-domiciled importer can simply buy into; the relevant question is whether a client's foreign counterparty or charterer is accessing it, which changes who bears the war premium under the sale contract. Second, the existence of a sovereign backstop tends to soften peak private rates over time, which is exactly what happened as Gulf AWRP eased toward roughly 1% of hull value by late March. Third, it signals that in the next chokepoint event, contract terms and state schemes, not insurer appetite alone, will set what cover actually costs your client.

India did not wait for a market solution. Under Operation Sankalp, the Indian Navy escorted Indian-flagged LPG carriers through the Gulf of Oman after they cleared Hormuz, with vessels such as the Jag Vikram completing transits carrying full LPG parcels. This is the operational reality that brokers have to translate into wording.

War-risk and Institute War Clauses cover is built around warranties and conditions: the assured must follow routing instructions, must not breach trading limits, and must declare material changes. A naval convoy or escort arrangement intersects with several of these. Joining or leaving a convoy, deviating to a muster point, or waiting at anchor for an escort window can all touch deviation, change-of-voyage and held-covered provisions. None of these are problems if they are anticipated in the placement; all of them are claims disputes if they are not.

What to build into Gulf-transit placements now

• Confirm the policy treats participation in a government or naval convoy as permitted and not as an unapproved deviation or breach of trading warranty.
• Agree held-covered terms in advance so that if a vessel is delayed at anchor or rerouted on naval instruction, cover continues at a pre-agreed additional premium rather than lapsing.
• Pin down the breach-of-warranty position: if a master follows a naval order that technically breaches a routing warranty, the wording should hold the assured covered on notice and reasonable additional premium.
• Align the war risk return-of-premium and cancellation timing with the actual fixture window, since these voyages are short and the seven-day war cancellation clause can otherwise outrun the transit.

The broader point: when a state runs the convoy, the state's operational decisions become facts the policy has to absorb. The placement that anticipates convoy mechanics protects the claim; the one that relies on standard clauses invites an argument about whether the assured did everything required of a prudent uninsured.

Pricing in a live chokepoint is unlike anything an annual cargo book teaches. The premium is not a function of loss history; it is a function of how dangerous the underwriter believes the next transit is on the day of fixture. That makes three things true that brokers should communicate to clients before, not after, the quote lands.

First, the rate is volatile by the day. Gulf AWRP ran from near 0.125% pre-crisis to a 2.5% to 5% peak and back toward roughly 1% within weeks. A quote held on Monday may not stand on Thursday. Importers planning multiple lifts should expect to re-quote each voyage and budget for a range, not a number.

Second, capacity is rationed by perceived safety, so a clean fixture with a credible routing and escort plan may attract cover when an identical cargo on an exposed routing cannot be placed at any price. This is where broker presentation earns its fee: a well-documented voyage plan, evidence of naval escort participation, and a clear statement of trading limits materially improve placeability.

Third, watch the interaction with the underlying sale contract. Under common Incoterms, the party bearing transit risk also typically arranges and pays for war cover, but a 5% AWRP spike can swamp the assumptions baked into a CIF or CFR price agreed months earlier. Brokers advising importers should flag that war premium escalation may need to be passed through under the contract, or hedged, rather than silently absorbed. A client who learns this from their broker before the lift is far happier than one who discovers it on the invoice.

A Gulf crisis does not only threaten total loss; it spreads claims across heads of cover that importers rarely model together. The first is general average. If a vessel under threat sacrifices cargo, diverts at expense, or incurs salvage and refuge costs to preserve the common maritime adventure, every cargo interest contributes in proportion to value. An Indian importer whose own parcel arrives untouched can still face a substantial general average contribution and a demand for a general-average bond and guarantee before the goods are released. War cover and the marine cargo policy must be checked to confirm that general average arising from a war peril is actually picked up, because the war and marine sections handle it differently.

The second is detention, blocking and trapping. Vessels that anchored for weeks outside Hormuz, or that were prevented from completing a voyage, raise questions about whether cargo is covered for the consequences of being trapped, and for how long. Institute War Clauses contain frustration and detention provisions and time limits that determine whether a stranded but undamaged cargo ever becomes a claim. Importers should not assume that delay alone triggers recovery.

The third is the hull-cargo coordination gap. With GIC Re having pulled hull war cover while cargo war was being re-priced separately, an importer could find the carrying vessel and the cargo aboard it sitting under different war-risk regimes, placed at different times on different terms. When a loss touches both, subrogation and contribution between hull and cargo insurers get messy, and the cargo owner can be caught in the middle.

The broker action here is to map, per shipment, which war regime covers the hull and which covers the cargo, whether general average from a war peril is recoverable, and what the detention clock looks like. That mapping is the difference between a clean recovery and a year of correspondence.

The acute phase has eased, but the structure the crisis exposed is permanent: in a chokepoint event, Indian importers face a domestic reinsurer that can exit a peril overnight, a private market that rations by safety rather than balance sheet, and foreign sovereign backstops they cannot directly access. That argues for preparation now, while rates are calmer.

A practical checklist for Gulf-exposed accounts

1. Build a Gulf-exposure register. Identify every client with crude, LPG, LNG, chemicals or containerised cargo that transits Hormuz or the wider Gulf, and tag the open covers involved.
2. Re-read each open cover's war and strikes section. Confirm whether war is included or excluded, the cancellation-notice period, and the automatic-termination triggers for the Gulf area.
3. Pre-agree held-covered and convoy terms with insurers before the next escalation, so cover continuance is a known additional premium, not a negotiation under fire.
4. Model the sale-contract pass-through. For CIF and CFR buyers, work out in advance who bears an AWRP spike and whether the contract permits recovery of escalated war premium.
5. Stress-test the general average and detention exposure on a representative shipment, so the client understands the contribution and bonding mechanics before a casualty, not after.
6. Document routing and escort participation as standard. Make the well-evidenced voyage plan the default submission, because in a rationed market information is what buys capacity.

The firms that did this in February were placing cover in March while competitors were reading their wordings for the first time. War risk is no longer a footnote on the cargo schedule. For any Indian importer whose supply chain runs through the Gulf, it is now a board-level exposure that the broker is expected to have mapped, priced and pre-arranged. Treat the 2026 Hormuz episode as the rehearsal it was, and use the calm to be ready for the next one.
