S&P Global Ratings issued a report on March 21, 2026, identifying critical vulnerabilities in the Gulf Cooperation Council (GCC) energy sector. The effective closure of the Strait of Hormuz disrupts global flows of crude oil, liquefied natural gas (LNG), and petrochemicals.
Recent escalations caused direct physical damage to energy infrastructure and security-driven operational slowdowns. These disruptions impact global energy prices, regional trade flows, and investor sentiment.
S&P Global identifies the duration of the closure as the most critical factor for market severity. Limited alternative sourcing options mean a prolonged disruption would restrict a substantial portion of the world’s energy supply.
