The Office of Financial Sanctions Implementation (OFSI) helps to ensure that financial sanctions are properly understood, implemented and enforced in the United Kingdom. OFSI imposes sanctions to freeze assets, prevent entry into or transit through territories and prevent direct or indirect sale, transfer or supply of defense articles. OFSI’s approach is to promote, enable, respond and change. Where there is suspected non-compliance, OFSI responds by intervening to disrupt attempted breaches and by addressing breaches effectively.
