U.S. Treasury Secretary Scott Bessent posted a before-and-after comparison on X claiming that the tankers that once filled Iran's main oil-loading terminal on Kharg Island are gone. He called the island a "monument" to the one thing the Iranian regime can still produce, which he described as failure. Bessent said the U.S. effort known as Operation Economic Outcast is cutting off the regime's oil lifeline and denying it money for terrorism, nuclear procurement and the lavish lifestyles of the IRGC elite. His claim is backed by independent data, since a Bloomberg analysis of ship-tracking data and European Union satellite images found that no tankers have docked at Kharg's crude-export terminals since late August. That is the longest stretch of inactivity at the island since the U.S.-Iran war began in February, and Kharg normally handles about 90 percent of Iran's crude exports.

The squeeze has been building for months. The U.S. has blockaded Iranian oil exports since mid-April, sanctioned business partners of Tehran under Operation Economic Outcast, and even struck Iranian tankers near Kharg after Iranian missile attacks on U.S. warships. Reports describe a plunging rial and soaring inflation, and Bessent says the regime's belligerence is punishing ordinary Iranians. Still, some analysts doubt that more pressure alone will settle the conflict, pointing to persistently high global energy prices, disrupted shipping through the Strait of Hormuz and reports that Iran is turning to land routes to get around the blockade. The big questions now are how long Tehran can absorb the pain and whether it will change course or dig in.
