The Islamic Revolutionary Guard Corps (IRGC) has issued a fresh maritime advisory, warning commercial vessels to maintain a distance of at least 10 miles from United States warships operating in the region.
The directive, aimed at preventing “potential provocations” and ensuring the safety of merchant shipping, marks a further tightening of the already precarious security situation in the Middle East’s vital waterways.
Iran’s Rationale for the Measure
Iranian officials stated that the measure is intended to minimize the risk of accidental confrontations or misunderstandings between international shipping and American naval assets, which Tehran frequently characterizes as a destabilizing presence in local waters, according to ISNA News Agency.
This latest instruction comes amid a period of heightened naval activity and serves as a blunt reminder of the geopolitical friction defining the Strait of Hormuz and the Gulf. By formalizing a ten-mile “buffer zone,” the IRGC is effectively asserting its role as a regional maritime regulator—a move likely to be viewed by Washington and its allies as an attempt to impede freedom of navigation.
Strategic Signaling and Global Concerns
Analysts suggest that while the advisory is framed as a safety precaution for commercial tankers, it functions as a strategic signal of Iranian readiness to monitor and challenge the movement of Western military vessels. The IRGC has previously harassed or seized commercial ships in the region, and this advisory could foreshadow more assertive enforcement.
The Strait of Hormuz, through which approximately 20% of the world’s oil passes, remains a flashpoint for US-Iran confrontation. Previous incidents have included mine attacks, drone shootdowns, and vessel seizures.
As global shipping firms weigh the risks of these contested corridors, the international community remains on high alert for any incidents that could disrupt the flow of global energy supplies. The US Fifth Fleet, based in Bahrain, has not yet officially responded to the IRGC’s advisory.
