Iran Extends Control South Of UAE Waters, Escalating Hormuz Shipping Crisis

On May 20, 2026, Iran’s Persian Gulf Strait Authority (PGSA) announced new maritime boundaries, asserting control over shipping lanes south of the UAE. This comes as the Strait of Hormuz remains largely blocked since February, when hostilities between Iran, Israel, and the United States intensified. The move has sparked strong diplomatic backlash.

Iran’s Maritime Claim

• Iran’s PGSA published maps marking controlled zones from Kuh-e Mubarak in Iran to south of Fujairah in the UAE, and from Qeshm Island to Umm al-Quwain.
• Iran declared that all vessels must coordinate transit with the IRGC Navy.
• The IRGC reported it had overseen the passage of 26 vessels in 24 hours, including oil tankers.

UAE’s Response

• Emirati presidential adviser Anwar Gargash dismissed Iran’s claim as a “pipe dream,” calling it an infringement on sovereignty.
• The UAE is accelerating construction of a new oil pipeline through Fujairah, expected to bypass Hormuz by 2027.

Global Implications

• Nearly 20% of global energy exports once passed through Hormuz; the blockade has already driven up jet fuel and crude oil prices.
• The FAO has warned of cascading agrifood shocks, predicting global food price crises within 6–12 months due to disruptions in fertilizer and seed supply chains.
• Gulf states, backed by the U.S., are pushing a UN Security Council resolution demanding Iran halt attacks, remove mines, and allow humanitarian aid passage.

War And Regional Tensions

• Iran accuses Gulf states of aiding U.S.-Israeli strikes, claims denied by the UAE and others.
• Retaliatory Iranian missile and drone strikes have already hit Gulf infrastructure.
• Analysts warn Iran’s attempt to extend control beyond its territorial waters risks widening the conflict and destabilizing global trade routes.
