Maritime Insurers End Persian Gulf War Cover

The withdrawal of war-risk coverage is not a complete insurance blackout but a seismic shift in how risk is priced. Shipowners must now negotiate expensive "buy-back" policies for each individual voyage through the designated high-risk zones. This moves the financial burden from a predictable annual premium to a volatile, per-trip cost, creating significant uncertainty in shipping budgets. This decision by major insurers like Gard, Skuld, NorthStandard, and the American Club was triggered by their own reinsurers pulling back. P&I Clubs operate by pooling liabilities and securing reinsurance for catastrophic claims. When the reinsurers, who backstop these massive potential losses, withdraw their capacity due to escalating conflict, the clubs are forced to issue cancellation notices to avoid massive financial exposure. London's Joint War Committee (JWC), which designates high-risk maritime areas, has expanded its listed zones in the region to include waters around Bahrain, Kuwait, Oman, and Qatar. This formal designation by the JWC, a body composed of underwriters from the influential Lloyd's and London company markets, directly influences insurance premiums, signaling to the global market that the risk of war, terrorism, and related perils has intensified. The impact on shipping has been immediate and severe, with vessel traffic through the critical Strait of Hormuz plummeting by over 80% in the days following the announcement. This chokepoint, through which about 20% of the world's oil consumption flows, has seen a dramatic reduction in transits, with at least 150 tankers anchoring in the surrounding waters, effectively halting a significant portion of global energy supply. War risk premiums have surged by as much as 500%, adding hundreds of thousands of dollars in extra costs for every shipment. For a supertanker valued at $100 million, the cost per voyage could jump from around $250,000 to $375,000. Some reports indicate that vessels with links to the US, UK, or Israel are facing premiums three times higher than other ships. This situation differs significantly from the "Tanker War" of the 1980s. During the Iran-Iraq conflict, around 540 vessels were attacked, and insurance rates spiked. However, shipping never completely stopped as Lloyd's and government-backed schemes provided a continuous, albeit expensive, layer of coverage. The current, more widespread withdrawal by the primary P&I clubs marks a new level of risk aversion in the commercial insurance market. The effective closure of the Strait of Hormuz is not the result of a physical blockade but of a financial one. Without proper insurance, vessels cannot legally or commercially operate; ports will deny them entry, banks won't finance their voyages, and cargo owners will not load their goods. This "invisible siege" by the insurance market demonstrates how commercial mechanisms can halt global trade faster than military action.
