What are the regulatory deadlines to watch in December?

‍EU

On December 1, 2025, the European Commission published Implementing Regulation (EU) 2025/2392 in the Official Journal of the European Union. The regulation provides the technical description of the categories of important and critical products with digital elements pursuant to Regulation (EU) 2024/2847 (Cyber Resilience Act – CRA).

The CRA lays down rules on the cybersecurity of products with digital elements. In particular, Annex III sets out categories of important products with digital elements that, when placed on the market, are subject to conformity assessment procedures that are stricter than those applicable to other products with digital elements. This regulation includes examples of products with digital elements whose core functionality meets the technical description of certain important or critical products with digital elements. The regulation enters into force on December 21, 2025, 20 days after its publication.

Canada

On November 20, 2025, the Office of the Superintendent of Financial Institutions (OSFI) removed outdated or redundant guidance and related documents from its guidance library. The list of rescinded documents applicable to financial services providers will be removed by December 31, 2025. According to the agency, this rescission will help the OSFI maintain effective oversight by focusing on relevant risks, eliminating redundancies and outdated expectations, simplifying guidance, and enhancing transparency and predictability.

Hungary

On June 16, 2025, the Hungarian government published a decree in the official gazette adopting a regulation on the implementation of certain obligations of entities supervised by the Hungarian National Bank (MNB) under the Act on the Prevention and Combating of Money Laundering and the Financing of Terrorism, as well as on the minimum requirements for the development and operation of a sanctions screening system.

With regard to the sanctions screening system, the regulation mandates the development of such a system and sets minimum operational requirements to implement financial and restrictive measures imposed by the European Union and the United Nations Security Council.

The regulation enters into force on July 1, 2025. However, the provisions concerning actions based on the customer's risk classification enter into force on September 1, 2025, and the provisions on the determination of a prominent public figure enter into force on December 31, 2025.

Hong Kong

The Hong Kong Monetary Authority (HKMA) has issued the revised return on liquidity monitoring tools MA(BS)23 which collects information from authorized institutions (AIs) on a set of liquidity monitoring tools to facilitate the HKMA’s on-going supervision and monitoring of liquidity risk.

The revised returns have been issued with an accompanying set of completion instructions providing AIs with a step by step breakdown for completing each section of the return. The HKMA states that the revised return will be available for download from the HKMA’s supervisory communication website (STET) in October 2025. Authorised Institutions will then be required to submit the revised returns via STET beginning December 31, 2025.
