Economic pressure can compel Tehran to moderate its destructive behavior and end its pursuit of nuclear weapons. Crude and natural gas exports historically account for 25% of government revenues: it is therefore important to accurately track Iran’s oil exports to interpret if sanctions are effectively stopping the flow of revenue to the regime.
This can be difficult given the regime’s track-record of smuggling and sanctions evasion techniques and there is little consensus among oil tracking agencies about how much is getting through, and to where.
This variance mars the accuracy of media reports, but it also presents a serious challenge to those trying to get a handle on the trajectory of the Iranian economy, given its oil revenue dependency.
More importantly, a correct accounting of quantities and destinations will help focus limited resources to where they are really needed: which shippers, which vessels, which areas, which ports, which flags, which insurers.
UANI has therefore sought to address the information gap with a new comprehensive ship-tracking methodology.
Using Automatic Identification System (AIS), satellite imagery, vessel comparison and tanker classification, and cargo datasets to uncover all under-the-radar ship-to-ship (STS) transfers and exports of Iranian oil and gas condensates, we generate what we contend are the most accurate figures available.
This resource seeks to disrupt Iran’s attempts to generate profits from oil sales and further isolate the regime economically.

Iran’s oil exports fell by more than 90% in May, as U.S. maritime enforcement of an American naval blockade severely disrupted Tehran’s sanctions‑busting network of ghost fleet tankers. Exports have fallen to record lows, with both total volumes and the number of loadings markedly reduced compared to previous months in 2026. Throughout the entire month, UANI recorded only four naphtha exports and an undetermined but limited volume of liquefied petroleum gas (LPG). No crude oil exports departed Iranian waters and successfully passed through the U.S. blockade.

As Washington tries to choke off Iran's oil exports, a “ghost fleet” of tankers moves crude to China through one of Asia’s busiest shipping corridors—hidden in plain sight.
Charlie Brown, UANI Senior Advisor, joined the Wall Street Journal onboard their vessel to help track the shadow fleet's elaborate high-seas deceptions up close and explained how these vessels are tracked.
In this clip he explains how UANI tracks how the Iranian regime avoids international sanctions.

Iran is at a critical juncture. Coordinated strikes by Israel and the United States have severely weakened Iran’s missile, nuclear, and terror proxy networks. In response, the regime is turning inward, escalating crackdowns on its own people. It is also fomenting terror abroad. The world must stay vigilant—any easing of pressure risks enabling Tehran to rebuild its lethal capabilities.
