William Hallatt is a partner in the Hong Kong office of Gibson, Dunn & Crutcher LLP. He is co-chair of the firm’s Global Financial Regulatory group and head of the Asia-Pacific Financial Regulatory practice. His full-service financial services regulatory practice provides comprehensive contentious and advisory support as a trusted advisor to the world’s leading financial institutions. His clients include global investment banks, wholesale and retail banks, hedge funds, private wealth managers, investment managers, insurers, cryptocurrency exchanges and major fintech firms.
Mr. Hallatt has extensive experience in handling both internal and external regulatory investigations, in particular high-stakes enforcement matters brought by key financial services regulators, including the Hong Kong Securities & Futures Commission (SFC) and the Hong Kong Monetary Authority (HKMA), covering issues such as IPO sponsor conduct, anti-money laundering and terrorist financing compliance, systems and controls failures, and cybersecurity breaches.
Mr. Hallatt routinely advises on new regulatory developments and compliance advisory matters, as well as the extraterritorial impact of third-country regulation, such as MiFID II and the EU Benchmark Regulation. He is a leading expert on culture, conduct and governance, having worked with regulatory bodies including the Financial Stability Board (FSB) on recent reforms in this area. He has also led the industry response on a number of the most significant regulatory change issues in recent years, working closely with senior figures from major regulators, including the SFC, HKMA, Hong Kong Insurance Authority (IA) and the Monetary Authority of Singapore (MAS), together with leading industry associations, including the Asia Securities Industry & Financial Markets Association (ASIFMA) and the Alternative Investment Management Association (AIMA).
Mr. Hallatt also has particular expertise in relation to the regulation of cryptocurrencies and other digital assets, and has advised the world’s leading cryptocurrency exchanges as well as regulated financial institutions on a range of key strategic matters in this space. This includes advising cryptocurrency exchanges on regulatory restructurings, high profile regulatory investigations and the handling of licence applications in multiple jurisdictions. Mr. Hallatt also frequently works with Gibson Dunn’s leading Funds Management team to advise investors on their investments into cryptocurrency-focused funds and the regulatory issues associated with such investments.
Mr. Hallatt has regularly been listed as a leading lawyer in Chambers Asia Pacific for both contentious and non-contentious regulatory work and is now also listed as a leading lawyer by the inaugural Chambers Greater China Region released in 2022, in which a client was quoted saying “He’s wonderful.” In the 2021 edition a client noted: “William has his ear to the ground when it comes to regulatory developments across Asia. He is the first person I speak to concerning regulatory developments and his advice is always practical and measured. His experience in regulatory investigations allows him to think several steps ahead as to where an investigation is heading.” Mr. Hallatt’s practice is also recognized by Legal 500 Asia Pacific, which highlights the practice as being “particularly adept at engaging with regulators such as the Hong Kong Securities & Futures Commission as well as the Hong Kong Monetary Authority.”
