OFAC 50% Rule: Ownership Math and Evidence for Compliance Teams
Under OFAC's 50 Percent Rule, an entity is treated as blocked when one or more blocked persons own, directly or indirectly, half or more of it in aggregate. That status applies automatically, even when the entity's name never appears on the SDN List, and U.S. persons generally may not transact with it absent specific authorization. The determination hinges on aggregation and indirect ownership tracing, not on the entity's own designation status.
