Every major Protection & Indemnity club has cancelled war risk cover for the Gulf. After midnight Thursday, no internationally insured vessel can legally transit the Strait of Hormuz.

Key takeaway

The P&I withdrawal constitutes a de facto international commercial embargo on Gulf energy exports — one imposed by private actuarial decisions rather than any government, and therefore not reversible by government decree alone.

Gard and NorthStandard, the two largest Protection & Indemnity clubs by insured tonnage, issued cancellation notices on Wednesday for the Persian Gulf, the Strait of Hormuz, and Iranian waters. They join American Steamship Owners Mutual P&I, London P&I Club, and Skuld, which issued notices earlier in the week . Lloyd's of London separately classified Iran, The Gulf, and parts of the Gulf of Oman as high-risk zones. Every major P&I club in the global maritime insurance system has now withdrawn cover, effective midnight Thursday 5 March.

P&I insurance is the structural backbone of international shipping. It covers third-party liability — collision, pollution, crew injury, cargo loss. Without it, no port authority will grant entry, no bank will finance a voyage, no flag state will permit a vessel to sail. A tanker without P&I cover is not merely expensive to operate; it is legally inoperable under the International Convention on Civil Liability for Oil Pollution Damage.

During the Iran–Iraq tanker war between 1984 and 1988, when more than 400 commercial vessels were attacked in The Gulf, insurance markets adjusted premiums sharply but never fully withdrew. Lloyd's war risk premiums reached 7.5% of hull value at that conflict's peak. A complete withdrawal of all major P&I clubs from an entire maritime region has no precedent in the modern insurance market.

VLCC daily freight rates had already hit $423,736 — an all-time record exceeding the 1991 Gulf War peak . Hormuz traffic was down 80% from pre-conflict levels . After midnight Thursday, the remaining traffic faces a binary choice: sail uninsured — which no major shipping line or flag state will permit — or stop. President Trump's government-backed insurance through the Development Finance Corporation covers political risk but does not replace P&I liability cover; they are different products addressing different legal requirements. Reinstatement after hostilities cease requires a full syndicated risk reassessment by each club's underwriting committee — a process that historically takes weeks, not days.

Deep Analysis

In plain English

Ships need two kinds of insurance to operate commercially: one that covers the ship itself from war damage, and another (P&I) that covers liability if the ship damages something else — a port, another vessel, or the environment. The companies providing both have now all cancelled coverage for the Gulf. Without insurance, banks won't finance the cargo, and ship owners won't risk losing a vessel worth $100-200 million with no cover. The US government promised to back insurance and provide naval escorts — but the Navy itself has confirmed it doesn't currently have enough ships to run an escort programme. The result is that the promise cannot be fulfilled in time to prevent commercial shipping through the Gulf from stopping almost entirely after Thursday midnight.

Deep Analysis
Synthesis

The P&I withdrawal achieves through private market mechanics what deliberate sanctions regimes rarely accomplish: a near-total commercial embargo without a single government imposing it. This mechanism — private actuarial decisions creating collective action that states cannot easily reverse — is novel in its effectiveness and in its immunity to diplomatic resolution. No ceasefire announcement, by itself, restores cover; underwriters will require a demonstrated period of stability before reinstatement, creating a commercial lag even after any political settlement.

Root Causes

The US Navy's convoy capacity gap reflects two structural constraints: (1) post-Cold War fleet reductions have left the US with approximately 290 battle-force ships versus the 600-ship Reagan-era fleet, with carrier strike groups already committed to the theatre leaving minimal surge capacity; (2) convoy escort requires not just surface combatants but organic ASW capability, minesweeping assets, and maritime patrol aircraft — a combined-arms commitment that cannot be rapidly assembled without drawing down other global commitments. The DFC insurance pledge was announced without coordination with the Navy on operational feasibility, creating the credibility gap the Navy's statement has now exposed.

What could happen next?

  • Consequence

    Gulf energy exports face near-complete commercial cessation after midnight Thursday absent an operational naval escort programme the US Navy has confirmed does not currently exist.

    Immediate · Assessed
  • Consequence

    South Korean and Japanese strategic petroleum reserves — approximately 50 and 90 days respectively at normal consumption — will begin drawdown within days, creating a government-level response imperative within weeks.

    Short term · Assessed
  • Consequence

    Cape of Good Hope rerouting will absorb tanker capacity and raise freight rates globally, affecting non-Gulf shipping lanes.

    Short term · Assessed
  • Meaning

    The trade finance credit freeze — banks will not issue letters of credit without P&I cover — creates a dual-barrier embargo that government insurance pledges alone cannot resolve.

    Immediate · Assessed
  • Risk

    If the US cannot operationalise the escort programme within 72 hours, the credibility of the Trump pledge collapses, potentially affecting Gulf state confidence in US security guarantees more broadly.

    Short term · Assessed
  • Precedent

    A successfully operationalised government war risk insurance framework would establish a new template for state intervention in shipping markets during conflict — potentially reshaping how future maritime crises are managed.

This Event
Last P&I clubs quit Gulf; Hormuz sealed
P&I insurance is the legal and financial precondition for commercial shipping — without it, vessels cannot enter ports, secure financing, or operate under any major flag state. The complete withdrawal converts a military conflict into a de facto commercial blockade of the world's most important oil chokepoint, with no precedent in the modern maritime insurance market.

Different Perspectives
South Korean financial markets
South Korean financial markets
South Korea, which imports virtually all its crude oil, is absorbing the war's economic transmission most acutely among non-belligerents. The second KOSPI circuit breaker in four sessions — with Samsung down over 10% and SK Hynix down 12.3% — reflects an industrial economy unable to reprice energy costs that have risen 72% in ten days. The market response indicates Korean industry cannot sustain oil above $100 per barrel without margin compression across manufacturing, semiconductors, and shipping.
Migrant worker communities in the Gulf
Migrant worker communities in the Gulf
The first confirmed civilian deaths in Saudi Arabia — one Indian and one Bangladeshi killed, twelve Bangladeshis wounded — fell on communities with no voice in the military decisions that placed them in harm's way. Migrant workers live near military installations because that housing is affordable, not by choice. Bangladesh and India face the dilemma of needing to protect nationals who cannot easily leave a war zone while depending on Gulf remittances that fund a substantial share of their domestic economies.
Azerbaijan — President Ilham Aliyev
Azerbaijan — President Ilham Aliyev
Aliyev treats the Nakhchivan strikes as a direct act of war against Azerbaijani sovereignty, placing armed forces on full combat readiness and demanding an Iranian explanation. The response is calibrated to maximise international sympathy while stopping short of military retaliation — Baku cannot fight Iran alone and needs either Turkish or NATO backing to credibly deter further strikes.

The Hormuz closure is an existential threat. Japan, South Korea, and India receive the majority of their crude through the strait — they will bear the heaviest economic cost of a war they had no part in.
