The Engine Room Problem And Why Machinery Failure Remains Shipping's Dominant Risk
The 2026 Allianz Safety and Shipping Review highlights machinery failure as the dominant cause of shipping incidents globally, compounded by the closure of the Strait of Hormuz following a US-Iran confrontation in early 2026, which has trapped over 1,500 vessels in the Persian Gulf with severe maintenance disruptions. These combined factors are expected to cause prolonged machinery breakdowns, port congestion, and significant supply chain disruptions across the Persian Gulf region and beyond.

LNG shipping stocks: The decline continues, but at a slower pace
Qatar has extended its force majeure suspension of LNG shipments from Ras Laffan until mid-August, with liquefaction units expected to resume only in early September, causing ongoing disruption to LNG exports through the Strait of Hormuz.

Japan's Mideast Crude Supply to Rebound in July as Stranded Vessels Exit Hormuz
Multiple Japanese-linked supertankers previously stranded in the Persian Gulf are now exiting the Strait of Hormuz, with 16 million barrels of Middle East crude aboard Japan-bound vessels departing this week, signaling a partial resumption of oil flows through the strait. Japan's crude imports had slumped to a 60-year low after Gulf supplies fell 68% year-on-year following the outbreak of conflict with Iran in February 2026, but supply is now expected to rebound in July as stranded vessels clear the strait and Saudi Arabia resumes loadings at Ras Tanura.
