OFAC Sanctions Update: Unblocking and Re-blocking Explained

You might care about this because the U.S. Treasury's Office of Foreign Assets Control, known as OFAC, recently made changes to its list of sanctioned individuals and organizations. This document, a Federal Register notice, tells us about these updates. On May 21, 2026, OFAC took action regarding two specific parties: Ayadi Chafiq Bin Muhammad and an organization called Lajnat Al Daawa Al Islamiyya.First, OFAC announced that these two parties were unblocked. This means their property and interests in property, which were under U.S. jurisdiction, were no longer considered blocked. They were removed from the Specially Designated Nationals and Blocked Persons List, often called the SDN List. This removal was done under an older version of Executive Order 13224, which deals with blocking property of persons who support terrorism.However, on the very same day, OFAC also announced that these exact same two parties were immediately blocked again. This re-blocking was based on a newer, updated version of Executive Order 13224. Specifically, OFAC determined they provided financial, material, or technological support to Al-Qaeda. This means that once again, all their property and interests in property under U.S. jurisdiction are blocked. U.S. persons are generally not allowed to do business with them. These actions show a continuous effort by OFAC to adjust and clarify its sanctions against those believed to be involved in terrorism support. This notice is particularly interesting because it shows how U.S. sanctions policy is applied and updated in practice. It is not common to see the same parties unblocked and then immediately re-blocked within the same announcement. This action indicates that OFAC carefully reviews its designations. It may remove entities from a list based on older legal reasons, but then re-list them under newer, more specific, or amended legal authorities. This ensures that the sanctions remain current and effective.The re-designation also highlights the ongoing efforts by the U.S. government to disrupt financial support for terrorist organizations like Al-Qaeda. It emphasizes that even if a party's status changes, the underlying reason for concern about their activities remains under close scrutiny. This process ensures that the legal basis for sanctions is solid and up-to-date. It also demonstrates the dynamic nature of international financial regulations and the commitment to combating terrorism financing through legal means. Many different groups would find this legal document relevant. Financial institutions, such as banks and investment firms, need to pay close attention. Their compliance departments must ensure they do not engage in transactions with blocked persons. They use the SDN List to screen their customers and dealings.Businesses involved in international trade, especially those with global operations, also need to know about these updates. They must avoid doing business with sanctioned entities to prevent legal penalties. Legal professionals specializing in sanctions law, international law, or anti-money laundering regulations would also find this document important for advising their clients.Furthermore, researchers and analysts focusing on U.S. foreign policy, counter-terrorism efforts, or international finance would be interested. It offers a direct example of how the U.S. government implements its policies. Finally, any individuals or organizations that have had past dealings with Ayadi Chafiq Bin Muhammad or Lajnat Al Daawa Al Islamiyya would need to understand these changes to ensure their compliance with U.S. law.
