The Office of Foreign Assets Control (OFAC), part of the U.S. Department of the Treasury, has published names of individuals added to the Specially Designated Nationals and Blocked Persons List (SDN List). These individuals have had their property and interests within U.S. jurisdiction blocked, and U.S. individuals and companies are generally not allowed to conduct business with them. The action was effective as of April 9, 2025. Further information about the sanctions can be found on the OFAC website.
Simple Explanation
The U.S. government has made a list of people they are not allowed to trade with because they might be doing bad things, and they are making sure these people can't use their money in the U.S. anymore.
