Her Majesty’s Treasury (HMT) is not responsible for the freezing of assets, neither does it hold them. The Office of Financial Sanctions Implementation (OFSI), which is part of HMT, ensures that financial sanctions are properly understood and implemented in the UK and it is for holders of assets subject to sanctions to ensure that they are frozen under the regulations.
(1) OFSI undertakes an Annual Review of frozen assets in the UK, requiring all persons or institutions that hold or control frozen assets in the UK to report to OFSI. Details of assets reported to OFSI for the 2018 Review are still being compiled and are not yet available.
(2) HM Treasury does not hold this information.
