Strait of Hormuz Closure Deepens Global Energy Shock Amid U.S.–Israel–Iran Conflict

Since the U.S.–Israeli strikes on Iran began on 28 February 2026, Iran’s Islamic Revolutionary Guard Corps (IRGC) has effectively sealed the 22-mile-wide Strait of Hormuz. U.S. forces have responded with a naval blockade of Iranian ports, while only three commercial vessels were recorded transiting the waterway in a 24-hour period. The strait, which normally carries roughly 20 percent of global oil and liquefied natural gas (LNG) flows, has become a strategic choke point whose closure fuels the largest supply disruption on record, according to the International Energy Agency (IEA).

The war follows a joint U.S.–Israeli campaign that targeted Iranian military sites, prompting Tehran to weaponise its control of the strait—a tactic long simulated in U.S. war-games. Iran briefly announced the strait open on Friday but reversed the decision hours later, citing the U.S. blockade as justification.

The Hill

• President Donald Trump – extended a 14-day cease-fire indefinitely and maintains the U.S. naval blockade.

The Hill

• IRGC Navy – issued threats against any vessel entering the strait.

The Hill

• Iranian Foreign Minister Abbas Araghchi – has floated a proposal for reopening in exchange for a pause in nuclear talks.

• U.S. Defense and Energy Officials – monitor the blockade’s impact on global markets.

• Traffic fell to as low as three vessels per day, compared with the pre-war 120–140.

Oil Price

• The strait’s disruption cuts ? 10 percent of world oil supply, equating to a loss of 1 billion barrels and a 5–6 million bpd demand-destruction estimate.

Bloomberg

• Brent crude rose to $106–$107 per barrel, about 50 percent above pre-war levels; U.S. crude reached $95 per barrel.

• Saudi Arabia’s East–West pipeline can move up to 7 million bpd (effective ? 4.5 million bpd); the UAE’s Habshan–Fujairah line handles 1.5–1.8 million bpd.

Higher oil prices have spurred “demand destruction” in petrochemical hubs across Asia and Europe, prompting airlines to cut thousands of flights and prompting diesel price spikes that threaten freight logistics. Economists warn that a three-month strait closure could push Brent above $190 per barrel, driving global inflation toward 7.7 percent and risking a recession.

Bloomberg

• Trump announced an indefinite cease-fire extension while keeping the naval blockade.

The Hill

• The IRGC warned, “Approaching the Strait of Hormuz will be considered co-operation with the enemy, and the offending vessel will be targeted.”

The Hill

• The IEA labeled the event “the largest supply disruption on record.”

Bloomberg

• Iran’s Deputy Parliament Speaker Ali Nikzad said, “If we place our foot on the throat of the Strait of Hormuz … 25 percent of the world’s economy would be affected.”

Alam Saleh (Australian National University) argued the U.S. blockade “helps Iran’s strategy” and is “not necessarily practical.” Economists such as Ryan Sweet (Oxford Economics) and Paul Krugman (CUNY) contend the shock could trigger a global recession if the closure persists beyond three months.

Iran and the United States have both announced temporary reopenings, yet real-time AIS data shows traffic remains near-collapsed. Insurance firms withdrew war-risk coverage in early March, effectively halting commercial navigation regardless of official statements. The timeline for de-mining and full mine-clearance remains unspecified.

Diplomatic overtures continue, with Iran’s foreign minister shuttling between Islamabad and Moscow while the U.S. weighs the feasibility of naval escorts. Parallel to negotiations, Saudi Arabia, the UAE, and Iraq are advancing pipeline projects (East–West, Habshan–Fujairah, Kirkuk–Ceyhan) that could collectively transport up to ? 10 million bpd if fully operational—a timeline measured in years rather than months. The interplay of diplomatic resolution, alternative export routes, and evolving insurance markets will shape the strait’s role in global energy flows for the foreseeable future.
