U.S. Targets Iran's Oil Revenue Channels

## Catalyst Analysis: U.S. Sanctions Turkish Bank for Aiding Iran

The U.S. Treasury Department on September 4 designated Istanbul-based Golden Global Yatirim Bankasi Anonim Sirketi, along with its subsidiaries Golden Global Portfoy Yonetimi and Golden Global Varlik Kiralama. These entities were added to the Specially Designated Nationals list, effectively barring them from the U.S. financial system. A general license was issued to permit the orderly wind-down of transactions involving these firms.

## Impact on Financial Flows

Treasury Secretary Scott Bessent stated that the initiative, dubbed Operation Economic Outcast, aims to target institutions helping Iran generate and move revenue. The department alleges Golden Global Bank facilitated tens of millions of dollars in transactions for the Islamic Revolutionary Guard Corps-Quds Force (IRGC-QF) and provided correspondent banking access enabling international fund movement. According to Treasury, the bank was instrumental in Iran's sanctions-evasion network, helping to transfer oil revenue from China to Turkey for conversion into cash and gold.

### Winners, Losers & Uncertainty

This designation serves as a warning to third-country financial institutions. Former Treasury official Andrew Sobotka noted that U.S. and G7 correspondent banks may increase pressure on their foreign partners to strengthen compliance. The strategy appears to be deterrence, aiming to make business with Iran too risky for financial institutions.

### Risk Watch — Legal/Timeline

While Golden Global Bank has denied the allegations and asserted compliance with banking regulations, the U.S. Treasury's actions highlight ongoing efforts to enforce sanctions against Iran. The effectiveness of these measures may depend on the willingness of other international financial players to comply with U.S. demands.
