How a Shadow Oil Empire Helps Iran’s Regime Cling to Power | Bloomberg Investigates

Revolutionary violence launched political ascent

Ali Shamkhani rose from poverty to become a top IRGC commander after joining the Mansouroun group, which assassinated oil executives during the 1979 revolution and later formed Ayatollah Khomeini's bodyguard.

Military control enabled smuggling infrastructure

As head of Iran's navy for four decades, Ali Shamkhani controlled Persian Gulf ports and terminals that became crucial chokepoints for sanction evasion and black market trade.

Nepotism placed son atop oil empire

Following a systematic purge where regime families seized private sector assets, Ali Shamkhani introduced son Hossein on national television in 2008, positioning him to capture Iran's lucrative oil trade.

Code name 'H' concealed billionaire operator

Hossein Shamkhani directed Milavous Group using aliases 'H' or 'Hector,' with employees forbidden from questioning his identity until sources confirmed his role after the company shed jobs in 2024.

India tanker seizure triggered Dubai expansion

After Admiral Group lost a vessel to Indian authorities in 2022, the network rapidly shifted to Dubai and scaled Milavous from five employees to over 200 while establishing offices in Switzerland and Romania.

Sprawling empire encompasses 115 entities

The investigation mapped approximately 115 affiliated companies, tankers, and individuals including Koban Shipping and Oceanlink Shipping, creating one of Iran's three largest oil trading networks.

Dark fleet manipulates global oil markets

The network utilized a 'dark fleet' representing roughly 10% of the world's tankers to conduct covert ship-to-ship transfers off Iraq's coast, blending Iranian crude with Iraqi oil to mask its origin en route to China and India.

Barter trade arms Russia's war machine

Beyond oil, the network shipped Iranian drones and dual-use components like microchips and gyroscopes across the Caspian Sea via Crios Shipping, receiving payment in Russian oil to circumvent dollar transactions.

Tens of billions flow through covert channels

The operation generated tens of billions of dollars in revenue, with concealment methods including false documentation, shell company payment routing, and vessels that disable tracking systems.

Major energy firms handled sanctioned crude

Oil traded through Shamkhani's network reached Western majors including BP and Chevron, demonstrating how sanctioned Iranian crude infiltrates legitimate global supply chains.

Prestigious banks provided critical leverage

Despite sanctions, network companies maintained relationships with JPMorgan, Standard Chartered, and other Western institutions through hedge funds like Ocean Leonid, enabling exponential financial growth.
