According to WPB, Recent statements from marine insurance underwriters confirm that war risk coverage for vessels passing through the Persian Gulf and the Strait of Hormuz will not return to pre-conflict terms immediately following the Iran-US understanding. This position directly affects the cost structure of all energy commodities transported through this waterway, including crude oil, refined products, and bitumen. For the Middle East region, the persistence of elevated insurance premiums means that the economic benefits of reopened shipping lanes will be partially offset by higher transit costs. Globally, the continued application of special war risk pricing mechanisms introduces sustained upward pressure on freight rates for cargoes originating from or passing through the Gulf, keeping delivered prices of Iranian bitumen above levels suggested by crude oil benchmarks alone.
A recent report from Insurance Business America indicates that market participants view the agreement as a positive step but emphasize that the path back to normal insurance conditions remains unclear. War risk premiums in the region are still running as much as thirty times above pre-conflict levels. According to data cited in that report, war risk premiums for the Persian Gulf increased from approximately 0.1 percent of hull and machinery value to around 1 percent as hostilities escalated. For vessels transiting the Strait of Hormuz specifically, rates initially climbed to approximately 7.5 percent before easing back to between 2.5 percent and 3 percent. An analysis from Howden Re described conditions across marine hull war, cargo war, and political violence markets as being under extreme pressure throughout the conflict period. Insurers expanded high-risk zones, increased war risk premiums, and intensified scrutiny of vessel movements as attacks on shipping and energy infrastructure mounted.
The same report explained that marine insurers have relied on seven-day cancellation provisions embedded in war risk policies. This mechanism allows them to withdraw coverage and reissue it at significantly higher rates as conditions change. Insurers designed this flexibility to respond to rapidly evolving conflicts. Even with a formal understanding between Iran and the United States, underwriters retain the ability to adjust pricing on short notice should security conditions deteriorate. A marine insurance executive quoted in the report stated that the market will want evidence that the agreement is holding and that vessels can transit safely before pricing fully normalizes, adding that this process does not happen overnight. The geography of the strait compounds these concerns, as the waterway is only about twenty-one miles wide at its narrowest point, creating what the executive described as a huge concentration of risk.
Analysis published by Arabian Gulf Business Insight warns that the peace deal should not be viewed as a reset button for Gulf shipping. Full financial normalization could take twelve to eighteen months or even longer. A senior strategist at Blue Water Strategy, a Rotterdam-based advisory firm, told the publication that under very optimistic assumptions, full operational recovery including cargo flows, port confidence, and shipping schedules could take three to six months. However, full financial normalization may take twelve to eighteen months or substantially more. The strategist explained that the kind of premium seen during the conflict does not disappear simply because a communique is signed. At the conflict peak, war risk cover for vessels transiting the strait reportedly reached 4 percent of vessel value for a seven-day period, compared with pre-crisis levels as low as 0.001 percent.
The same report highlighted a structural vulnerability that markets have long underpriced. Gulf energy is not merely a commodity story but a chokepoint story. Even if vessels resume passage through the strait without incident, underwriters are unlikely to price the route at pre-war levels any time soon. The report further noted that the draft deal includes the lifting of United States sanctions on Iranian commodities, potentially allowing Iranian crude, petrochemicals, metals, and shipping services to re-enter global markets more openly. This introduces a significant competitive dynamic as Iran, after nearly four months of war and a punishing naval blockade, is likely to seek to monetize its resources rapidly.
An analysis published by AInvest framed the insurance bottleneck as the real obstacle to shipping resumption. According to that report, six hundred vessels remained stuck in the Persian Gulf recently not because the waterway was actually blocked but because no insurer would cover them to cross it. War risk insurance premiums for crossing the Strait of Hormuz had risen roughly four thousand times their pre-crisis level. A ship worth one hundred million dollars that used to pay a very small fraction of that amount as a war risk premium now faces costs that can exceed the profit on the entire voyage. Major insurers in the Lloyd's market, which covers more than one third of the world's war risk coverage, suspended or repriced coverage for the region. As a result, commercial traffic effectively froze even after active shooting stopped.
The AInvest analysis quoted a major tanker company chief executive who stated recently that shipowners are not waiting for the war to end. They are waiting for the threat assessment to be downgraded, because that downgrade tells insurers the water is safe enough to price and tells ship captains they will not be sunk if a deal frays. The Joint Maritime Information Center, the coalition body that sets threat levels for naval and commercial traffic in the region, recently cut the Hormuz threat assessment from critical to severe. The analysis described this as a step but not the final one. The six hundred ships will not all leave on day one but will leave as the insurance market catches up. Even with a severe assessment, insurers need to be convinced that the deal holds. A ceasefire that frays is worse than a closed strait, as it leaves ships in the water with no protection and no way out.
The World Ports Organization reported that multiple international marine insurers had issued cancellation notices terminating war risk coverage for vessels operating in the Gulf region. New policy wording explicitly excludes all war risk claims arising from Iran and Iranian waters, including its coastal waters within twelve nautical miles offshore, as well as the entire Persian Gulf and its adjacent waters. A senior researcher cited in the report stated that the escalation of the Middle East situation has made geopolitical risk a core factor in war risk pricing, and from a long-term global perspective, this signals a shift in global shipping insurance pricing logic. Leading Protection and Indemnity Clubs, including Gard, Skuld, North Standard, West of England, and the American Club, have issued formal notices of cancellation for certain war risk covers. Most cancellations took effect following standard notice periods.
The World Ports Organization further explained that the withdrawal of annual coverage does not mean insurance disappears entirely. Instead, it shifts the cost burden sharply upward. Market estimates suggest marine hull rates for Gulf transits could rise by twenty-five to fifty percent, with some cases potentially doubling. Several clubs are offering reinstatement through voyage-by-voyage buy-back arrangements, which provide limited coverage at materially higher premiums, with maximum limits up to two hundred million dollars. The Joint Maritime Information Center has elevated the regional maritime risk level to critical. Insurance availability has become a primary gating factor for transit decisions. Severe GPS interference and AIS disruptions have been reported particularly near the Iranian coast, creating additional navigational risks.
For the bitumen sector specifically, these insurance conditions translate directly into sustained higher delivered costs for Iranian material. Bitumen exporters who anticipated an immediate return to pre-war freight and insurance costs now face a more gradual adjustment period. The gap between theoretical prices based on crude oil benchmarks and actual delivered prices will persist for several months at minimum. Buyers in Asia and Africa who resumed purchasing Iranian bitumen following the understanding should factor in continued elevated war risk surcharges when calculating landed costs. Insurance underwriters have signaled that their cautious stance will remain in place until they observe consistent and uninterrupted safe transits through the strait for an extended period. The current estimate among market participants is that war risk premiums for Iranian bitumen cargoes may stabilize at approximately 1 to 1.5 percent of cargo value for the remainder of the year, compared to 0.1 percent or lower in pre-conflict conditions.
