Russia-Ukraine War 2026Background
OFAC is the US Treasury bureau that administers and enforces American economic sanctions. It maintains the Specially Designated Nationals list, designates people and organisations under programme authorities, and issues licences that define lawful exceptions or wind-down periods. Its work spans Iran, Russia, Cuba, North Korea and cyber-threat programmes.
The bureau turns sanctions policy into operating rules for banks, insurers, shippers and other firms exposed to the US financial system. A designation can block dealings with a named party, while a general licence can permit narrowly defined transactions for a stated purpose or period. On 14 July, OFAC paired designations of tankers and Iran's central bank with General Licence Z for winding down existing cargo deals.
This combination of listing and licensing gives OFAC practical influence over transactions that touch US dollars, US banks or US-connected businesses. Its authority also reaches supply chains: on 15 July, it designated a network accused of procuring weapons parts for Iran's Revolutionary Guard, including Russian nationals and a Moscow firm.
OFAC closes Iran aviation relief
OFAC used Executive Order 13902 on 8 September to blacklist 27 Iranian airlines plus nine overseas intermediaries. It suspended General Licence J-1 and issued General Licence DD for firms unwinding temporary aircraft-sojourn dealings.
On 10 September, its licensing division began presuming denial of Iran-specific applications, retaining only legally compelled approvals and safety cases involving life, limb or the environment. For OFAC, the combined measures narrowed a prior exception regime while setting defined exit routes for outstanding aviation business.
OFAC targets a banking route
On 4 September, OFAC designated Golden Global Yatirim Bankasi and two affiliates, alleging links to transactions for the Islamic Revolutionary Guard Corps Qods Force and correspondent-banking access. General Licence CC gave counterparties until 19 September to unwind existing business.
OFAC's action turned an alleged financing route into a compliance Deadline for the bureau's counterparties. On 8 September, Golden Global closed three funds to new subscriptions after saying they were legally separate from its sanctioned parent bank. The case shows how an OFAC designation can reach beyond the named institution into related financial products.
OFAC reaches Cuban intermediaries
On 3 September, OFAC designated Cuba's state trade-finance bank, four fuel and mining traders, and Fidel Ernesto Castro Calis. It issued General Licence 4A on the same day, easing an embassy carve-out.
That pairing shows the bureau can distinguish between targets and permitted dealings inside one programme. On 20 August, OFAC directly designated Cuba's Ministry of Construction alongside the nickel-mining monopoly and two trading firms. From OFAC's perspective, the campaign extends its target set from commercial companies into state institutions and their intermediaries.
