Treasury Report: U.S. Sanctions and Blockade Crippling Iran's Economy

Treasury Report Claims U.S. Sanctions Decimate Iran Economy

The U.S. economic isolation campaign against Iran has pushed the country’s headline inflation to 90 percent in September following the launch of Operation Economic Outcast in late August, according to a Treasury Department report released Friday and covered by The Hill. Treasury Secretary Scott Bessent stated during a CNBC appearance that the financial pressure effort has been very successful at restricting Tehran’s access to international markets and diminishing the value of the Iranian rial.

Operation Economic Outcast Triggers Currency Collapse and Inflation Surge

According to Axios, the unofficial rial exchange rate hit a record low of 2,687,000 Iranian rials per U.S. dollar in October, reflecting a loss of roughly a quarter of its value since August. The Treasury report notes that this currency decline erodes domestic purchasing power, increases the cost of basic goods, and makes foreign inputs significantly more expensive for the regime. Fox Business reported that Bessent estimated Iran’s gross domestic product could contract between 20 percent and 25 percent.

Strait of Hormuz Blockade Halts Iranian Oil Shipments

Tehran’s oil supplies have suffered severe disruptions due to ongoing U.S. sanctions and a naval blockade in the Strait of Hormuz. The Treasury Department stated that Iran has not loaded any crude oil onto vessels since August 25, the day after Bessent announced Operation Economic Outcast, leaving the country with nothing after selling off remaining supplies stranded at sea. Yahoo reported that the blockade has prevented at least $25 billion in Iranian crude exports, cutting off the regime’s primary source of foreign revenue.

Borders and Alternative Financial Channels Face Severe Bottlenecks

Beyond maritime trade, the U.S. campaign has targeted commercial aviation, formal banking networks, and digital-asset infrastructure. The Treasury Department reported that it is disrupting cryptocurrency exchanges, wallets, and financial facilitators used to circumvent restrictions, freezing approximately $350 million in Iranian crypto assets. Axios detailed that overland export routes have also encountered major bottlenecks at borders with Pakistan, Turkey, Afghanistan, and Turkmenistan, leaving thousands of transport trucks stranded with delays of up to 20 days at the Turkish border.

Domestic Fuel Prices Rise as Questions Remain Over Military Aid

Critics of the Trump administration’s dual military and economic campaigns have pointed to domestic fiscal fallout within the United States, including rising energy costs. AAA figures cited by The Hill showed the average price of a standard gallon of gas in the U.S. reached $4.20 on Friday afternoon, marking a roughly 38 percent increase from a year ago. Meanwhile, while Bessent asserted in The Jerusalem Post that the economic strain has left the Iranian regime unable to pay its troops and regional proxies such as Hezbollah, Hamas, and the Houthis, separate Lebanese security sources reported that Hezbollah has spent recent months rearming and preparing for potential hostilities following earlier cash transfers from Tehran.
