US Treasury Secretary Bessent will be making direct asks to ministers at G20 to sever economic leakage that sustains the Iranian regime and the IRGC, reports FBN

• He will discuss Iran-related activity Treasury has identified in specific nations and make clear that the United States will be uncompromising in targeting any source of the regime’s illicit revenue.
• The source says the Secretary is scheduled to have nearly a dozen bilateral meetings with a variety of foreign finance leaders where he will raise this directly to them.

Direct minister-to-minister pressure of this kind follows an established US playbook: sanctions enforcement has historically tightened not through new designations alone but through Treasury leaning on intermediaries, the banks, refiners, shippers and commodity traders in third countries through which sanctioned revenue flows. Past episodes of maximum-pressure enforcement have tended to work in sequence: private warnings first, then designations of facilitators, then secondary-sanctions exposure for institutions that continue to clear the flows. The transmission channel for energy markets is the discount on sanctioned barrels and the cost of the shadow logistics that move them; tighter enforcement compresses the volume reaching market or raises the freight and insurance premium on what does, which is where enforcement campaigns have typically shown up in crude differentials rather than headline supply balances. The bilateral format matters: multilateral G20 communiques on sanctions have historically been diluted, whereas one-on-one asks allow Treasury to name specific entities to specific jurisdictions, and the follow-on tell is whether designations against facilitators in the named countries materialise in the weeks after the meetings. Actors that have previously absorbed such pressure without full compliance are the ones to watch; enforcement campaigns of this kind have tended to be leaky at the margin rather than absolute. Gold and safe-haven FX have historically responded to escalation risk from such campaigns only when enforcement spills into open confrontation.
