The United Nations has formally urged member states to reject Iran’s assertion of exclusive sovereignty over the Strait of Hormuz, challenging Tehran’s unilateral establishment of a body to control international maritime traffic through the waterway.
The International Maritime Organization (IMO) issued the directive, emphasizing that the strait remains an international transit zone under global law rather than a national domain subject to unilateral Iranian regulation.
This diplomatic escalation intensifies the geopolitical risk premium embedded in global energy markets.
The Strait of Hormuz serves as the primary conduit for a significant share of the world’s seaborne oil and liquefied natural gas.
Any attempt by Iran to enforce unilateral control or disrupt transit flows would trigger immediate volatility in Brent crude and shipping freight rates, as traders price in the potential for supply bottlenecks and insurance cost spikes.
The UN’s intervention follows Iran’s recent rejection of US-led efforts to coordinate regional security around the waterway.
