Iran Strikes Gulf States, Tanker Traffic Plummets at Hormuz

Iran launched missile and drone strikes against five Gulf countries on Sunday, July 12, directly targeting energy infrastructure and U.S. military assets, according to OilPrice.com. The attacks on Qatar, Bahrain, Kuwait, Oman, and Jordan mark a significant regional escalation following U.S. strikes on Iranian targets.

The conflict has immediately throttled maritime traffic through the critical Strait of Hormuz. Tanker traffic through the strait collapsed to just six vessels on Sunday, the lowest number in five weeks, Reuters reported citing Kpler data. By early Monday, no ships were visible on tracking systems attempting to transit the chokepoint.

In response to the heightened danger, oil and LNG tankers are once again switching off their AIS transponders to travel in "dark mode," a tactic used to avoid detection. Maritime intelligence firm Windward reported eight dark vessels active in the eastern approaches to the Strait of Hormuz on July 12, with none transmitting location data.

The attacks caused confirmed damage to energy infrastructure. In Kuwait, a drone struck an offshore drilling platform operated by Kuwait Oil Company, OilPrice.com reported. Oman reported attacks in regions bordering the southern Hormuz corridor. Qatar, the world's largest LNG exporter, intercepted ballistic missiles over Doha, temporarily suspending all civilian marine activity.

The security crisis has prompted a major operational shutdown. Qatar's Transport Ministry issued an urgent advisory suspending all maritime vessel activity until further notice. Windward noted this was "the first blanket maritime suspension by a Gulf state since the conflict began," which could directly impact LNG exports from Ras Laffan.

For Bakken operators, the disruption at the Strait of Hormuz—a passage for about 20% of global oil consumption—creates immediate upward pressure on global benchmark prices. Any sustained closure or significant reduction in flows from the Persian Gulf would increase the competitive advantage of domestically produced crude from secure basins like the Bakken.

The escalation follows a pattern of attacks on commercial shipping. Last week's Iranian strikes on commercial vessels near the strait prompted the return to dark-mode transits. The U.S.-Iran memorandum of understanding, which had previously led to a rise in observable tanker traffic, appears effectively suspended.

Regional military alerts are at a peak. Bahrain has placed all military units at the "highest level of readiness." Iran's Islamic Revolutionary Guard Corps claimed the strikes targeted U.S. bases, including Al Udeid Air Base in Qatar and the U.S. Navy’s Fifth Fleet headquarters in Bahrain, though U.S. Central Command reported no American personnel were injured.

The situation presents a clear and present danger to global energy supply stability. With tanker traffic at a five-week low and key exporters suspending maritime activity, global markets are facing a renewed supply shock. North Dakota producers are monitoring the situation for its impact on the differential between Bakken crude and international benchmarks.
