Iran's joint military command has declared sole control over the Strait of Hormuz, warning all oil tankers to use approved routes [1].

This assertion of sovereignty over one of the world's most critical oil transit chokepoints threatens to disrupt global energy markets and escalate military tensions in the Persian Gulf. The move comes as Iran seeks to counter regional pressure and perceived threats from the U.S. [2].

Between June 25 and June 28, 2026, Iranian authorities issued a series of warnings regarding maritime traffic [3]. An Iranian military spokesperson said that all oil tankers moving through the Strait of Hormuz must use approved routes or face a "forceful response" [1].

On June 28, 2026, Iran publicly declared its right to full control of the waterway [4]. This declaration occurred as the Iranian government brushed aside threats from President Donald Trump to "complete the job" of the war [4].

Officials said that the measures are intended to ensure the control of maritime traffic, and assert sovereignty over the strategic waterway [2]. The Iranian military said that any vessel attempting to transit without permission or outside of designated routes is responsible for the consequences [3].

International observers note that the Strait of Hormuz is a vital artery for global oil shipments. The threat of a "forceful response" against unauthorized transits creates a volatile environment for commercial shipping companies operating in the region [1].

Iranian authorities have not provided a specific list of the approved routes, but they have emphasized that the joint military command will monitor all movements within the Persian Gulf [3].

“Iran's joint military command has warned that all oil tankers moving through the Strait of Hormuz must use its approved routes or face a 'forceful response.'”

By claiming exclusive authority over the Strait of Hormuz, Iran is leveraging its geographic position to create a strategic deterrent against U.S. influence. This move challenges the international principle of 'transit passage' and could lead to a maritime standoff if the U.S. or other global powers attempt to escort tankers through non-approved routes to maintain the free flow of oil.
