The OFAC 50% rule
A risk-based approach becomes even more critical when applying complex guidance, such as the OFAC 50% rule. This rule extends sanctions compliance beyond individuals or entities named on the Specially Designated Nationals (SDN) list. Any company that is 50 percent or more owned, directly or indirectly, by one or more sanctioned parties is also considered a blocked entity, even if it does not appear on any official list.
In a recent enforcement action, private equity firm IPI Partners was penalized for indirect dealings with Russian oligarch Suleiman Kerimov, who was on the SDN list. Though Kerimov did not directly own 50 percent of the involved entity, OFAC determined that his control and benefit were sufficient to trigger enforcement under the 50% rule.
This case underscores why sanctions compliance cannot rely solely on list matching. Institutions must have systems and trained staff in place to analyze ownership structures, document decisions, and escalate concerns when red flags appear.
