Another Tanker Attacked Near Strait of Hormuz, Intensifying Middle East Shipping Risks

Reports from the UK Maritime Trade Operations and vessel tracking data indicate that on July 21, 2026, a tanker was struck by an unidentified projectile in waters northeast of Oman's Lima. As security conditions in the Middle East continue to deteriorate, risks for maritime transport through crucial international waterways like the Strait of Hormuz and the Red Sea are escalating further, posing severe challenges for crude oil shipments in the region.

Data reveals a dramatic plunge in vessel traffic through the Strait of Hormuz. According to research data from S&P Global Commodity Insights, the average daily number of tankers transiting the strait in the week ending July 19 plummeted to 7 from 16 the previous week, with Tuesday seeing the waterway essentially at a standstill. Due to the frequent attacks, risk appetite has sharply declined for major global shipping firms such as South Korea's Sinokor and Greece's Dynacom. Some very large crude carriers bound for the Persian Gulf have been forced to deviate from their planned routes or seek safety in the Arabian Sea.

Simultaneously, the security situation in the Red Sea remains concerning. Yemen's Houthi group recently announced it would impose a blockade on shipping bound for specific targets, including the Ras Tanura port of Saudi Aramco. This has prompted international shipowners transiting the Bab el-Mandeb Strait and the Gulf of Aden to heighten their security preparedness. Some affected vessels are responding to potential threats by flying flags of non-involved nations, altering their Automatic Identification System broadcasts, and deploying armed guards.

Market analysis notes that the Strait of Hormuz is a critical global chokepoint for crude oil transportation, and disruptions to its traffic directly threaten the stability of the international energy supply chain. Presently, numerous international shipping companies are on high alert. If the regional situation does not ease in the short term, global crude oil shipping costs and risk premiums are expected to climb further.
