The Hong Kong Monetary Authority (HKMA), the Securities and Futures Commission (SFC), the Insurance Authority (IA) and the Mandatory Provident Fund Schemes Authority (MPFA), working with Hong Kong Cyberport Management Company Limited (Cyberport), have launched the Generative Artificial Intelligence (GenAI) Sandbox++ initiative. Building on the GenAI Sandbox introduced in 2024, the expanded programme is designed to support financial institutions in developing and testing generative AI use cases with supervisory guidance and technical support, including complimentary access to graphics processing unit (GPU) computing resources at Cyberport’s AI Supercomputing Centre. GenAI Sandbox++ broadens coverage across banking, securities and capital markets, asset and wealth management, insurance, mandatory provident fund (MPF), and stored value facilities. It retains a focus on risk management, anti-fraud and customer experience, and continues to promote “AI vs AI” approaches that use AI to manage AI-related risks; illustrative use cases include AI-enabled insurance underwriting and claims processing, automated assessments of suitability requirements in investment product distribution, AI-powered tools for handling MPF, and cross-sector applications such as customer chatbots and advanced fraud detection systems.
