On March 9, the U.S. Treasury Department’s Office of Foreign Assets Control (OFAC) announced sanctions against “39 entities constituting a significant ‘shadow banking’ network,” pursuant to Executive Order 13846. OFAC explained that this network is “one of several multi-jurisdictional illicit finance systems,” which grants sanctioned Iranian entities access to the international financial system and obfuscates sanctioned entities’ trade with foreign customers. “Iran cultivates complex sanctions evasion networks where foreign buyers, exchange houses, and dozens of front companies cooperatively help sanctioned Iranian companies to continue to trade,” Deputy Secretary of the Treasury Wally Adeyemo said in the announcement. “Today’s action demonstrates the United States’ commitment to enforcing our sanctions and our ability to disrupt Iran’s foreign financial networks, which it uses to launder funds.” The action follows previous designations of six Iran-based petrochemical manufacturers or their subsidiaries, as well as three firms located in Malaysia and Singapore, for their involvement in the sale and shipment of petroleum and petrochemicals on behalf of a previously designated company (covered by InfoBytes here).
