Iran Announces 'New Rules' For Strait of Hormuz as US Refuses to Lift Naval Blockade

Iran announced on Saturday that it will enforce what it described as “new rules” governing waters along its coastline in the Arabian Sea and the Strait of Hormuz, signalling a further escalation in maritime tensions with the United States. The statement came as Washington reaffirmed that its naval blockade of Iranian ports would remain in place until freedom of navigation in the region is restored to levels seen before late February.

According to Iranian state-linked reports, the Islamic Revolutionary Guard Corps Navy said it would exercise stronger control over nearly 2,000 kilometres of Iran’s coastline. Iranian authorities said the new framework would make surrounding waters a source of security, prosperity and national pride. However, no detailed operational rules were immediately disclosed.

The Strait of Hormuz remains one of the world’s most strategically important waterways, handling a major share of global oil and gas shipments. Any disruption in the narrow maritime corridor can rapidly affect international energy prices and supply chains. The latest Iranian announcement is therefore being closely watched by markets and governments worldwide.

Earlier this week, Iran reportedly offered to reopen the Strait in exchange for the lifting of the US naval blockade, while suggesting that discussions on its nuclear programme be delayed to a later phase. Washington rejected that proposal, indicating it wanted broader commitments and immediate progress on key security issues before easing pressure.

Reports have also suggested that some commercial vessels navigating the area have faced pressure to alter routes and move through waters controlled by Iran. Claims of toll payments and increased interference by fast attack boats have added to concerns among shipping operators and insurers. These developments have raised freight risks and maritime security costs.

The United States has maintained that its naval measures are aimed at protecting lawful navigation and preventing coercion in international shipping lanes. With both sides holding firm positions, tensions in the Gulf remain high despite ongoing diplomatic backchannel efforts. Any further escalation in the Strait of Hormuz could have serious geopolitical and economic consequences well beyond the region.
