Washington Targets Shahr Bank Network in 8th Round, Warns Regional Exchange Houses of Sanctions

On August 7, 2026, the US Department of the Treasury imposed new sanctions targeting an extensive network linked to Iran's Shahr Bank, including entities in the UAE, Hong Kong, and Singapore, in the eighth round of maximum sanctions campaigns launched by the US administration this year against Tehran's sources of funding.

The statement issued by the Office of Foreign Assets Control (OFAC) revealed that the Shahr Bank network includes more than ten financial and commercial entities operating in several countries, led by Titan Exchange in Dubai, which held tens of millions of dollars on behalf of Shahr Bank, and Alps International in Dubai, which facilitated transactions worth hundreds of millions in multiple currencies, along with front companies in Hong Kong and Singapore and individual clients.

Secondary sanctions represent the most prominent consequence of this round, as the Department of the Treasury has the authority to prohibit or restrict dollar correspondent accounts for any foreign financial institution conducting significant transactions on behalf of sanctioned entities. Consequently, regional exchange houses and banks that previously dealt with networks linked to Shahr Bank now face the risk of being cut off from the international dollar payments system.

This round comes amid an escalating trajectory; on July 10, the Treasury targeted Iranian exchange houses with front entities in the UAE and Hong Kong, while previous rounds covered shipping networks and intermediaries in the oil market. This gradual escalation exerts compounding pressure that narrows Iran's financial maneuvering space, though it does not imply an immediate cessation of revenues as long as alternative networks operate outside the dollar sphere.

What Do These Terms Mean?

Secondary Sanctions: Sanctions affecting non-US parties simply for dealing with a targeted entity, aiming to isolate them from the international financial system even without a direct connection to the United States.

Correspondent Account: An account held by a foreign bank at a US bank to execute dollar transfers; access to it is severed as soon as the foreign bank is listed under secondary sanctions.

OFAC (Office of Foreign Assets Control): The sanctions enforcement arm of the US Department of the Treasury, which issues sanctions lists and executes related enforcement actions.

Front Companies: Legal entities used to conceal the identity of the true owner or the source of funds, operating outwardly as ordinary commercial businesses.

Exchange Houses: Financial institutions focused on currency exchange and money transfers, serving as a key link in sanctions-evasion networks due to their small size and relatively weak oversight.
