Many of our clients have heard of the OFAC 50 Percent Rule — but aren’t entirely sure what it really means or how it affects their business. The rule is both significant and far-reaching, with implications that extend well beyond the surface. In this post, we’ll break down what the rule actually is, explain why it requires deeper due diligence, and outline practical steps your organisation can take to identify and mitigate hidden sanctions risks.
The Office of Foreign Assets Control (OFAC) of the U.S. Department of the Treasury enforces economic and trade sanctions based on U.S. foreign policy and national security goals. Among its most critical and far-reaching regulations is its 50 Percent Rule, introduced in 2014.
Any entity that is owned 50 percent or more, directly or indirectly, by one or more blocked (i.e. sanctioned) persons is itself considered a blocked person—even if it is not explicitly listed on OFAC’s Specially Designated Nationals (SDN) List.
This rule ensures that sanctioned individuals cannot circumvent restrictions through affiliated businesses or layered corporate structures.
Note: While OFAC’s rule does not formally apply to “control,” OFAC may still designate entities under broader sanctions programmes based on influence or other factors.
Indirect ownership is defined as a situation where the blocked person holds ownership through other entities that are themselves 50% or more owned by the blocked person.
This means firms must examine all levels of the ownership chain, which may involve:
Failure to identify a blocked entity—even unintentionally—can lead to:
