Iran's Hormuz authority announced on May 20, 2026 [1], that it claims control and oversight of waters south of the United Arab Emirates' port of Fujairah.
This move represents a significant escalation in regional tensions, as the Strait of Hormuz is one of the world's most critical chokepoints for global oil shipments. By asserting regulatory authority over these waters, Iran seeks to influence shipping lanes and potentially implement its own fee structures for vessels passing through the area.
Also known as the Persian Gulf Strait Authority, the Iranian body aims to establish sovereignty and regulatory control over the strategic waterway [2, 3]. While some reports focus on the waters south of Fujairah [4], other accounts indicate that the claim extends to two UAE ports, specifically Fujairah and Umm Al Quwain [5]. Some reports further suggest that ports in Oman may also be affected by these claims [3].
The UAE has rejected these assertions. The dispute centers on the Iranian authority's attempt to draw new lines of control around the Strait of Hormuz to consolidate its influence [2, 5]. This consolidation effort reportedly includes the use of island checkpoints, and various diplomatic deals to secure Iranian interests in the region [2].
Iran's strategy involves a combination of administrative declarations and physical presence to enforce its oversight [2]. The Hormuz authority intends to use this position to monitor shipping traffic and collect fees from maritime operators [2, 3]. This challenge to established maritime boundaries creates a volatile environment for international shipping companies and neighboring Gulf states.
Regional officials have condemned the move as a violation of sovereignty. The UAE said these waters fall under its own jurisdiction and that the Iranian claims have no legal basis in international maritime law [6].
“Iran's Hormuz authority announced on May 20, 2026, that it claims control and oversight of waters south of the United Arab Emirates' port of Fujairah.”
The assertion of control by the Persian Gulf Strait Authority is an attempt by Iran to transition from a regional power to a regulatory gatekeeper of the Strait of Hormuz. By claiming oversight of waters near UAE ports like Fujairah, Iran is testing the resolve of the UAE and its international allies. If successful in imposing fees or checkpoints, Iran could gain significant economic and political leverage over the global energy supply chain, potentially altering the security architecture of the Persian Gulf.
