DUBAI / SINGAPORE — The global energy crisis reached a fever pitch on Thursday, March 19, 2026, as the Islamic Republic of Iran formalised a "selective blockade" in the Strait of Hormuz. While the waterway remains a graveyard for Western-linked shipping, new maritime intelligence and satellite data confirm that Tehran is now actively vetting and granting passage to vessels from nations it deems "strategic partners," even as it chokes off the energy supply to the United States and its allies.
The $112 Barrel and Market Volatility Brent crude futures skyrocketed by over 4% this morning, trading at approximately $112.30 per barrel, while U.S. West Texas Intermediate (WTI) surged toward $100. Financial analysts at Goldman Sachs and Citi have warned that the persistent closure of this narrow chokepoint—through which 20% of the world’s oil and LNG normally flows—could push prices as high as $150 within the next month. The current spike follows yesterday’s retaliatory strikes on Qatar’s Ras Laffan facility, which signaled that no energy infrastructure in the Gulf is safe.
A Permission-Based Transit System Iranian Foreign Minister Abbas Araghchi reiterated today that the Strait is "not closed," but clarified it is only accessible to those who are not "enemies of the resistance." Maritime tracking data from firms like Windward and Clarksons Research support this claim. In the last 48 hours, at least five vessels—primarily Indian-flagged LPG carriers and Chinese-flagged bulkers—were observed exiting the Persian Gulf via a specific diversion through the Larak-Qeshm Channel under Iranian observation.
These "friendly" ships are reportedly required to transmit specific identification codes and, in some cases, undergo digital vetting by Iranian naval authorities before being allowed to transit. This "permission-based control" has effectively split the world’s merchant fleet into two tiers: those who can navigate the Gulf and those whose assets remain trapped. As of today, an estimated 1,100 non-locally trading vessels remain stranded inside the Persian Gulf, unable to risk a transit without naval escorts.
Escorts and Escalation In Washington, U.S. Secretary of War Pete Hegseth stated that the Pentagon is fast-tracking plans for a multi-national naval coalition to break the blockade. President Donald Trump has promised "unrelenting focus" on reopening the waterway, suggesting that U.S. warships will soon begin escorting tankers through the 33-kilometer-wide passage. However, maritime insurance premiums have already reached prohibitive levels, with some providers refusing to cover any hull entering the Gulf of Oman.
The impact is being felt most acutely in Asia. In New Delhi and Seoul, governments are scrambling to manage fuel shortages, as nearly 80% of their cooking gas and industrial oil typically transits through Hormuz. While Iran is shielding its own exports—averaging 1.5 million barrels per day to China—the rest of the world is watching a slow-motion economic decoupling take place at one of the world's most vital maritime intersections.
