What Are Secondary Sanctions?
Secondary sanctions explained - and why jurisdiction does not exempt your agent.
TL;DR
TL;DR: Primary sanctions prohibit US persons from transacting with designated parties. Secondary sanctions extend the reach - foreign persons can face designation for significant transactions with sanctioned parties, even with no US nexus.
The distinction
Primary: US persons, US-origin goods, USD transactions. Secondary: non-US persons who facilitate or materially support sanctioned activity - banking, trading, or clearing for designated parties.
Why it matters for agents
An agent operating outside the US is not automatically outside OFAC's reach. A payment agent that clears for a sanctioned party can create secondary-sanctions exposure for its operator.
The posture
Screen counterparties against the SDN list and applicable international lists, document controls, fail closed. The same stack, whichever jurisdiction you operate from.
