The conflict between Iran and the US-Israeli alliance expanded dramatically on March 1, 2026, as sustained Iranian strikes against Gulf states caused widespread disruption to commercial shipping through the Strait of Hormuz — the narrow waterway through which approximately one-fifth of global oil supplies transit daily.
Strait of Hormuz Under Threat
Maritime authorities reported that several commercial vessels had been forced to halt transit through the strait as Iranian military activity in the area intensified. The International Maritime Organization issued an emergency advisory warning all vessels to avoid the waterway until further notice.
Iran’s navy and IRGC naval forces reportedly deployed fast attack craft and laid mines in approaches to the strait, according to US naval officials. At least two commercial tankers reported near-misses from Iranian anti-ship missiles, though no direct hits on civilian vessels were confirmed on this date.
Gulf Defense Operations
Bahrain, which hosts the US Navy’s Fifth Fleet headquarters, reported coming under particularly heavy attack. The small island nation’s defense forces, working alongside US military assets, engaged multiple incoming threats throughout the day.
The United Arab Emirates and Saudi Arabia also reported intercepting Iranian projectiles targeting both military installations and civilian infrastructure. Saudi air defenses were activated across the country’s eastern provinces, which house the kingdom’s critical oil infrastructure.
Energy Market Panic
The disruption to Strait of Hormuz shipping sent shockwaves through global energy markets. Crude oil futures surged dramatically as traders assessed the potential for a prolonged closure of the waterway.
Energy analysts warned that even a temporary disruption to Hormuz shipping could have cascading effects on global supply chains. Approximately 21 million barrels of oil pass through the strait daily, making it the world’s most critical energy chokepoint.
Humanitarian Concerns
International organizations raised alarms about the humanitarian impact on Gulf state populations. The attacks on civilian infrastructure, including power stations and water desalination plants, raised concerns about the welfare of millions of residents — including large expatriate communities — across the region.
Several embassies in Gulf capitals began issuing advisories urging their citizens to consider departing, while commercial airlines scrambled to maintain evacuation routes amid the deteriorating security situation.
International Shipping Response
Major global shipping companies, including Maersk, MSC, and CMA CGM, announced they were suspending all transits through the Strait of Hormuz effective immediately. The Lloyd’s of London insurance market designated the entire Persian Gulf as a high-risk zone, causing maritime insurance premiums to spike.
Alternative shipping routes, including the longer passage around the Cape of Good Hope, were being assessed by logistics companies, though analysts warned these diversions would significantly increase shipping costs and delivery times for energy supplies.
Military Assessment
Western military analysts noted that Iran’s targeting of Gulf shipping infrastructure appeared designed to maximize economic pressure on the US-led coalition. By threatening the Strait of Hormuz, Tehran was leveraging one of its most potent strategic assets — its ability to disrupt global energy flows.
US naval forces in the region were reportedly conducting mine-clearing operations while maintaining a defensive posture around allied Gulf ports, though the scale of the Iranian threat stretched available resources.
