U.S. Sanctions Iran’s Strait of Hormuz Authority as Global Oil Markets Face Turmoil

The United States has imposed new sanctions on the Persian Gulf Strait Authority, the organization established by Iran to oversee transit requests through the Strait of Hormuz, according to a statement released by the U.S. Treasury Department on Wednesday. The move marks another escalation in tensions between Washington and Tehran as concerns over global energy security continue to grow.

The Strait of Hormuz is one of the world’s most critical oil shipping routes, carrying nearly 20% of the global oil supply. Iran’s increasing control over the strategic waterway has already disrupted international markets and triggered fears of prolonged instability in global trade and energy prices.

Tehran shut down the strait following the outbreak of war involving the United States, Israel, and Iran on February 28. The closure sent shockwaves through financial and energy markets, intensifying concerns about supply chain disruptions and rising fuel costs worldwide.

According to the Treasury Department, any individual, company, or entity cooperating with the Persian Gulf Strait Authority could face sanctions for potentially supporting Iran’s Islamic Revolutionary Guard Corps (IRGC). U.S. officials warned that providing services to the authority may be interpreted as assisting organizations linked to the Iranian military.

Treasury Secretary Scott Bessent sharply criticized Tehran’s latest actions, stating that Iran’s attempts to pressure international maritime trade demonstrate the regime’s financial desperation. He described the strategy as an effort to exploit one of the world’s most important shipping chokepoints for economic and political leverage.

The sanctions announcement follows the release of a new map by the Persian Gulf Strait Authority last week. The map reaffirmed Iran’s territorial claims over a broad section of waters surrounding the Strait of Hormuz, further heightening geopolitical tensions in the Middle East.

Analysts warn that continued instability around the Strait of Hormuz could have major consequences for global oil markets, shipping operations, and international trade in the months ahead.
