Strait of Hormuz Closure Drives US Manufacturing PMI to 4-Year High
Impact Assessment Rationale
Loss pathway: Confirmed closure of the Strait of Hormuz—a JWC listed area and one of the world's critical shipping chokepoints—directly engages Marine Hull, Marine Cargo, and War Risk books across multiple Lloyd's syndicates. Evidence: Article explicitly states the US-Israeli war against Iran has closed the Strait of Hormuz, causing acute disruption to shipping of energy, aluminium, and fertilizers; supplier delivery index at 60.6 and prices-paid at 82.1 confirm ongoing systemic supply chain stress. Limit: This is an economic and supply-chain impact article; no specific vessel casualties, insured loss quantum, or claims figures are cited, but the strait closure alone is sufficient to trigger war risk additional premiums, JWC listed area notifications, and potential reinsurance reserving actions.

Summary
The US ISM Manufacturing PMI jumped to 54.0 in May 2026, its highest level since May 2022, driven by companies front-loading purchases amid supply chain disruptions caused by the closure of the Strait of Hormuz following the US-Israeli war against Iran. The closure has caused severe disruption to shipping of essential commodities including energy, aluminium, and fertilizers, with supplier delivery times stretched to 60.6 points. This supply chain stress and attendant inflation—with the prices-paid index at 82.1—has significant implications for marine cargo, energy, and war risk books in the London market.

A US blockade of Kharg Island, Iran's primary oil export terminal, has caused a collapse in Iranian oil exports despite record volumes being redirected through the Jask terminal. Infrastructure constraints at Jask severely limit the bypass capacity, meaning total Iranian crude export volumes remain heavily depressed. This has significant implications for Energy and Political Risk books covering Iranian oil infrastructure, sanctions-linked exposures, and Persian Gulf energy flows.
With the US blockading Kharg Island, Iran has maxed volumes from Jask. But infrastructure constraints severely limit flows.

The Dutch government has approved a €993 million subsidy for state-owned EBN Capital BV to replenish severely depleted gas reserves, with storage currently at under 16% capacity compared to 36% last year. The intervention follows a 50% surge in European gas prices attributed to the Iran War and effective closure of the Strait of Hormuz, which has disrupted LNG flows. Additionally, Vopak and Gasunie have conditionally agreed to extend the Eemshaven LNG terminal operation to 2036.
Benchmark European natural gas has surged about 50% since the start of the Iran War, slowing progress in replenishing the region's gas storage sites ahead of winter. The region's inventories are just over 40% full, well below the five-year seasonal average of 54%, while competition with Asian buyers for liquefied natural gas cargoes looks set to intensify as flows through the critical Strait of Hormuz remain effectively halted.

تأتي هذه الطفرة الإنتاجية في وقت أدت فيه الحرب الأميركية الإسرائيلية ضد إيران إلى إغلاق مضيق هرمز، مما تسبب في اضطرابات حادة في شحن السلع الأساسية وارتفاع تكلفة منتجات حيوية مثل الطاقة والألمنيوم والأسمدة.
