Assessment

Medium-High confidence: 5/5 signals corroborated across 5 independent sources

Iran's IRGC has declared new maritime exclusion zones, initially near the Strait of Hormuz and subsequently expanded to include significant portions of the Gulf of Oman and Arabian Sea, extending from Chabahar. While the exact boundaries, enforcement mechanisms, and specific sanctions for unauthorized vessels remain unclear, this represents a confirmed escalation of Iranian assertiveness in critical international shipping lanes. The move is claimed to be a response to a US blockade and is reportedly concurrent with Iran and Oman nearing a toll-based entry-exit arrangement for the Strait of Hormuz.

Why it matters: This expansion directly threatens global oil flows and international trade, increasing regional conflict risk and challenging maritime security in a vital chokepoint.
