US sanctions three Iranian currency exchange firms

US sanctions three Iranian currency exchange firms The US Treasury Department announced sanctions against three Iranian foreign exchange companies, accusing them of helping Tehran convert oil revenues into currencies more easily used by the Iranian military and its regional proxies. The targeted firms, Opal Exchange, Radin Exchange and Tahayyori Guarantee Society, along with their associates, are now barred from the US financial system. Treasury Secretary Scott Bessent said the action reflects Washington's commitment to disrupting Iran's financial networks.
