The widening conflict in the Middle East has paralyzed shipping through the vital waterway, choking off critical energy flows from the region
Oil prices held near multi-month highs on Thursday as attacks on tankers and the escalating conflict in the Middle East disrupted shipping through the Strait of Hormuz, one of the world’s most critical energy chokepoints.
The US–Israeli war with Iran entered its sixth day, with Washington and its ally expanding strikes across the Islamic Republic. Tehran has responded with waves of missile and drone attacks on Israeli and American targets, warning that further retaliation could follow.
What’s happening to energy prices?
Brent crude extended gains on Thursday to trade above $82 a barrel, up more than 2% and at its highest level since January 2025. US West Texas Intermediate closed at $74.66 on Wednesday, its highest since June for a second straight day. Both benchmarks have surged more than 10% this week amid fears that prolonged disruptions to Gulf exports could tighten global supplies.
Gas prices spiked on Monday after Qatar halted LNG production following attacks in the Middle East. Benchmark Dutch and British wholesale gas prices jumped nearly 50%, while Asian LNG prices rose about 39%.
Why is the Strait of Hormuz important?
The strait carries about one-fifth of the world’s oil exports as well as roughly 20% of its LNG, including shipments from Gulf producers such as Saudi Arabia, Iraq, the UAE, Kuwait and especially Qatar.

According to Iranian state media, a senior commander for Iran’s Revolutionary Guard said the strait is closed and that it would set any ship trying to pass through on fire. Iran technically cannot close the Strait of Hormuz, but the mere threat of retaliation has been enough to prevent ships from sailing through the waterway.
At least 200 ships, including oil and LNG tankers as well as cargo ships, remained at anchor in open waters according to Reuters estimates, based on ship-tracking data from the MarineTraffic platform.
The conflict widened on Wednesday when the US sunk an Iranian warship near Sri Lanka. The strike came as US President Donald Trump pledged measures to protect energy shipments from the Middle East, including insurance support and potential naval escorts for tankers carrying oil and gas.
Trump said on Tuesday that the US Navy could begin escorting oil tankers through the Strait of Hormuz if necessary, adding that he had ordered the US International Development Finance Corporation to provide political risk insurance and financial guarantees for maritime trade in the Gulf.
Russian President Vladimir Putin said the shipping disruptions could open opportunities for Russia to expand energy exports. “Against this backdrop, we can look for new buyers who have lost supplies that previously moved through the strait,” he said, suggesting Moscow could redirect oil and gas shipments to alternative markets as Gulf flows face a halt.
How are maritime insurers reacting?
The strikes have prompted marine insurers to cancel war-risk coverage for vessels in the region, a move expected to push shipping costs sharply higher.
Insurers including Gard, Skuld, NorthStandard, the London P&I Club and the American Club said the cancellations would take effect from March 5, according to notices posted on March 1. Shipping companies operating in the region will now need to secure new cover, likely at far higher cost.
War-risk premiums have surged to as much as 1% of a vessel’s value in the past 48 hours, up from about 0.2% last week, industry sources said. For a $100 million tanker, that would raise the cost of coverage for a single voyage from roughly $200,000 to about $1 million.
The disruption has also triggered a surge in tanker freight rates. Spot costs to charter very large crude carriers (VLCCs) jumped to about $315,000 per day this week, up 77% from the previous Friday and roughly five times higher than in late December, according to shipping data cited by market participants.
What’s the outlook?
Banks and analysts warn that if shipping disruptions persist, crude could approach $100 per barrel. UBS this week raised its outlook for Brent prices for 2026, citing the escalating conflict and the risk of further strikes on energy infrastructure.
Analysts say the trajectory of prices will largely depend on whether shipping can resume safely or whether the conflict deepens further.
