The Office of Foreign Assets Control (OFAC), the US Treasury's sanctions arm, designated Hezbollah-aligned Lebanese officials Sleiman Frangieh and Mahmoud Qamati alongside the Alaa Hamieh financial network on 18 June, in an action published as sb0535 1. The network runs across Lebanon, Syria, Iraq and Oman, and the designation expanded an earlier 20 March action against the same operation. Treasury Secretary Scott Bessent said "Hezbollah must disarm for Lebanon to achieve a secure and prosperous future" and that Treasury would keep targeting the group's financial networks 2.
The instrument names no Iran relief. The Islamabad memorandum's promised OFAC waiver for Iranian crude exports stayed unsigned through Friday and Saturday , so the one Treasury action around the signing pressed against Hezbollah's funding rather than easing Tehran's. US Central Command (CENTCOM) had ended its 66-day naval blockade on 18 June ; the military lock opened while the economic one Iran was promised stayed shut.
Sanctions work as separate chains, and this one cuts where the deal needs slack. Bessent's disarmament framing ties Lebanon's relief to a Hezbollah concession no party can deliver inside a 60-day window, while a designation against the group's financiers runs directly against the de-escalation the MOU needs to hold. Treasury would argue enforcement and relief move on different programmes; the sequencing is what reads, with the instrument that fired pointed at one party and the instrument that was promised still in the drawer.
