The Strait of Hormuz blockade is severely disrupting global energy supply, with rising attacks on ships and a sharp decline in traffic through one of the world’s most important oil and gas routes.
The waterway, which carries about one-fifth of global crude oil and liquefied natural gas in normal conditions, has been largely paralysed since the war began on February 28, following US and Israeli strikes on Iran.
Security risks have increased rapidly since then. The United Kingdom Maritime Trade Operations reported that at least 27 commercial vessels, including 13 tankers, have been attacked or faced incidents in the Gulf, the Strait of Hormuz and nearby waters.
In the latest incident, a tanker linked to Qatar’s energy sector was hit by missiles near Ras Laffan, the world’s largest LNG export hub. All 21 crew members were evacuated safely, although the vessel was damaged and one unexploded projectile remained onboard.
The conflict has also taken a human toll. The International Maritime Organization confirmed that at least 11 seafarers and port workers have died in incidents since early March.
Shipping activity has dropped sharply. Data shows vessel crossings have fallen by more than 90 percent compared to normal levels. In peacetime, around 120 ships pass through the strait daily, but only a handful are now making the journey.
Thousands of vessels remain in the wider Gulf region, including hundreds of oil and gas carriers, reflecting the scale of disruption to global trade and energy flows.
Some ships have used an alternative route near Iran’s Larak Island, but access remains restricted. Iranian authorities have warned that vessels linked to hostile countries may not be allowed safe passage.
Sanctions have also influenced shipping patterns, with a large share of remaining crossings carried out by vessels under US, EU or UK sanctions.
Energy analysts warn that the ongoing blockade is increasing pressure on global oil and gas markets, driving price volatility and raising serious concerns about supply security.
Restoring safe navigation through the Strait of Hormuz is now seen as critical to stabilising global energy markets and preventing further disruption
