Iran Expands Strait of Hormuz Claim
Analysis based on 6 articles · First reported May 12, 2026 · Last updated May 13, 2026
The expansion of Iran's claimed operational area in the Strait of Hormuz could significantly disrupt global oil and liquefied natural gas supplies, as about a fifth of the world's supply passes through this strait. This geopolitical move by Iran, amidst its conflict with the United States and Israel, introduces increased uncertainty and potential for conflict in a critical shipping lane, likely leading to higher shipping insurance costs and volatile energy prices.
Iran has announced a significant expansion of its definition of the Strait of Hormuz, transforming it into a 'vast operational area' far wider than previously recognized. Hamad Akbarzadeh, deputy political director of the Islamic Revolutionary Guard Corps Navy, stated that the strait's width is now considered to be between 200 and 300 miles, a substantial increase from the previous 20 to 30 miles. This expansion is the second such announcement by Iran since the start of its conflict with the United States and Israel, following a previous declaration of a new zone of control along the United Arab Emirates' Gulf of Oman coastline. The Strait of Hormuz is a crucial gateway for global oil and liquefied natural gas supplies, with countries like Saudi Arabia, Iraq, and Qatar relying on it for exports. This move by Iran is expected to heighten geopolitical tensions and potentially impact international shipping and energy markets.
