US Sanctions 35 Entities Over Iran’s Parallel Banking System
US Treasury sanctions 35 entities tied to Iran’s parallel banking system, alleging they laundered oil revenues and funded arms procurement and proxy operations.
Strong U.S. Action Targets Iran’s Parallel Banking Network
The U.S. Treasury announced on Tuesday that it has imposed sanctions on 35 entities and individuals for their role in what it described as Iran’s parallel banking system. The Treasury said these networks helped channel tens of billions of dollars through opaque channels to skirt sanctions and support Tehran’s military and proxy activities.
The announcement, attributed to the Office of Foreign Assets Control (OFAC), framed the move as a disruption of a covert financial pipeline that has enabled illicit oil sales and the procurement of weapons-related components. Officials warned that the measures are intended to cut off critical revenue streams to Iran’s armed forces and affiliated groups.
Scope of the Sanctions: 35 Entities and Individuals Identified
The measures announced target a mix of companies, intermediaries, and individuals alleged to have facilitated transactions that bypass international restrictions. OFAC identified actors across multiple jurisdictions who allegedly processed payments, concealed beneficial ownership, or provided transactional services for illicit revenue flows.
Treasury officials said the designated parties played roles ranging from oil revenue transfers to procurement financing and onward remittances to Iran-linked organizations. The listings will block U.S. persons from engaging with the designated parties and can expose any non-U.S. institutions that transact with them to secondary sanctions.
Allegations: Illicit Oil Revenues and Arms Procurement
According to the Treasury, the parallel banking system enabled the flow of proceeds from unlawful oil sales into accounts accessible by Iran’s military apparatus. Those funds were then used to obtain sensitive missile components and other items for weapons systems, the agency said.
The Treasury further alleged that the financial channels supported transfers to groups aligned with Iran, amplifying regional security risks. Officials emphasized that stopping these flows is central to preventing further proliferation and to reducing the funding available for operations that threaten U.S. forces and regional partners.
Warning Over Strait of Hormuz Transit Fees
In a notable element of the announcement, OFAC cautioned that companies paying so‑called “transit” or passage fees to the Iranian government or the Islamic Revolutionary Guard Corps (IRGC) for passage through the Strait of Hormuz could face significant sanctions. The Treasury framed such payments as direct financial support to state or paramilitary actors.
The warning was positioned as a preventive step to deter commercial arrangements that might appear routine but, according to officials, serve as conduits for state-directed revenue. This advisory extends the reach of enforcement beyond traditional banking channels to maritime and logistics payments tied to strategic waterways.
Regional Trade and Financial Network Implications
Analysts say the designations could complicate trade routes and financial arrangements in a region already sensitive to sanctions risk. Banks, shipping firms, insurers and commodity traders that operate near Iranian markets may need to reassess compliance controls and due diligence procedures to avoid exposure.
The move is also likely to prompt tighter scrutiny by correspondent banks and increased demands for transparency in transactional records. Regional economies that have indirect ties to designated networks could see short-term disruptions as actors seek safer, compliant channels for trade and payments.
Enforcement, Coordination and Next Steps
The Treasury indicated that the sanctions are part of an ongoing effort to detect and disrupt illicit finance that benefits Iran’s military and proxy networks. Officials said they will continue to coordinate with international partners and use intelligence and financial forensic tools to identify additional facilitators.
Sanctions specialists note that enforcement will hinge on global cooperation and the willingness of non-U.S. jurisdictions to act on designation evidence. Treasury also signaled that entities facilitating or accepting payments linked to the designated networks face “severe consequences,” underscoring a policy posture aimed at deterrence.
This action follows a sustained U.S. emphasis on choking off revenue streams used to procure weapons and fund militant activity. The Treasury’s move places new compliance burdens on firms operating in maritime services, oil trading and cross-border payments, and signals continued pressure on networks that lawmakers and officials say enable Tehran’s military ambitions.
