Leaked Records Reveal Iran’s Shadow Banking Network Remains Largely Untouched by US Sanctions

Key points

• Leaked documents from Bank Parsian show that 15 foreign banks in China and the UAE facilitated international transactions for Iran between 2022 and 2023, despite existing US sanctions.
• Only two of these 15 banks were targeted by the US in August; 13 have faced no penalties, with Banque Misr’s UAE branch being the primary node for dollar access.
• The network uses 'rahbar' companies and 'trustee accounts' to obscure the origin of funds, allowing sanctioned Iranian entities to move money through non-sanctioned intermediaries.
• US Treasury Secretary Scott Bessent indicated further sanctions are coming, including potential actions against major Chinese banks, but Washington has avoided targeting large institutions to prevent wider financial disruption.
• Iran’s trade has contracted sharply, with non-oil exports down 30% and oil exports to China falling by 40% year-on-year, yet the shadow banking infrastructure remains resilient.

Background

This development follows the US launch of 'Operation Economic Outcast' in August 2026, which included the suspension of General License G, cutting off educational services for Iranians, and the Section 311 designation of Banque Misr’s UAE branches. Previous coverage noted that while Washington aimed to choke Tehran’s hard currency access, the initial moves targeted only specific branches rather than the broader network of exchange houses and front companies in Dubai, Istanbul, and Baghdad. The current investigation highlights that despite these measures, the underlying infrastructure for moving funds remains largely intact.

How outlets are covering it

Iran International emphasizes the scale of the evasion, noting that the US crackdown missed 13 of the 15 identified banks and that the network relies on human intermediaries rather than just financial engineering. Al Jazeera highlights the US Treasury’s aggressive stance, with Secretary Bessent threatening 'financial violence' and signaling potential sanctions against Chinese banks, while rejecting claims of US reluctance to confront Beijing. Both sources agree that the US is shifting from targeting Iranian entities to the foreign financial infrastructure, but Iran International suggests the current measures are insufficient to stop the flow of funds, whereas Al Jazeera frames the ongoing pressure as part of a broader campaign to isolate Tehran amid stalled truce talks.

Why it matters

The persistence of Iran’s shadow banking network undermines the effectiveness of US economic pressure, allowing Tehran to continue funding its regime and military operations despite sanctions. If Washington fails to target the remaining foreign banks, particularly in China and the UAE, Iran may retain the ability to finance imports and evade restrictions, prolonging the conflict and complicating diplomatic negotiations. The situation also raises concerns about the global financial system’s vulnerability to sanctions evasion and the potential for wider economic disruption if major Chinese banks are targeted.

What to watch

The US Treasury is expected to announce sanctions against another bank this week, potentially targeting a major Chinese institution. Washington is also engaging with G20 finance leaders to encourage cooperation against Iran, while Iran’s Finance Minister has dismissed the sanctions as ineffective. The outcome of these diplomatic and economic maneuvers will determine whether the shadow banking network is further constrained or continues to operate with minimal disruption.
