Iran insists the Strait of Hormuz will remain closed until US sanctions and military blockades are lifted, following a massive US crude transport operation and exchange of strikes.

Tensions in the Strait of Hormuz have intensified following a major US military operation that transported millions of barrels of crude oil through the strategic waterway using air, sea, and space assets. Iranian forces responded by deploying rocket-launched sea mines, prompting retaliatory US strikes against Larak Island.

Tehran subsequently stated that the strait "will not be opened" until Washington complies with conditions in a memorandum of understanding. Iran's demands include an end to military threats, the lifting of port blockades, suspension of energy sanctions, and the unfreezing of Iranian assets. Prior to the conflict, approximately 20 million barrels of crude oil passed through the passage daily. Analysts warn that a narrowing window for both nations to exert pressure significantly heightens the risk of further regional escalation.
