These amendments primarily aim to implement the capital standards and the associated requirements on disclosure and exposure limits promulgated by the Basel Committee on Banking Supervision (“BCBS”) in relation to the prudential treatment of cryptoasset exposures. The opportunity has also been taken to revise certain provisions, mainly to better align with international practices and to enhance clarity or consistency within our regulatory framework. The rules will be tabled before the Legislative Council on 16 July 2025 for negative vetting, subject to which they should come into operation on 1 January 2026, in line with the BCBS’s timeline. We will inform you once the negative vetting process has been completed. Yours faithfully, Donald Chen Executive Director (Banking Policy) cc: The Chairperson, The Hong Kong Association of Banks The Chairperson, The DTC Association FSTB (Attn: Mr Timothy Wong)
