    Barnabas (Barney) Reynolds is a partner in the Firm’s Financial Services Group. He is recognised as a leading financial institutions practitioner advising across a wide range of financial services matters, including mergers and acquisitions, governance, investigations and enforcement actions, AML and sanctions, and regulatory aspects of transactional matters involving banks, asset managers, insurers, derivatives, financial markets and infrastructure, payments, fintech, cryptocurrencies and digital assets.

    Barney finds solutions to complex situations. He advises financial institutions, boards, and other senior executives on risk management, regulatory changes, and compliance. He frequently engages with policymakers and regulators on complex domestic and cross-border financial services matters.

    Barney has extensive expertise advising on UK and EU regulation, as well as navigating legal and regulatory systems worldwide. He has a broad practice advising clients on numerous high profile matters across the UK, Europe and the Middle East, including Bank of America, Barclays, Citi, Deutsche Bank, ICE, Morgan Stanley, Société Generale and Wells Fargo. He helped numerous financial institutions during the 2008 financial crisis, the Eurozone crisis of 2009-2012, and the Credit Suisse and Silicon Valley Bank situations. He has played a significant role in the development of financial regulatory regimes, including advising on the establishment of the Abu Dhabi Global Market (ADGM), and work relating to the Dubai International Financial Centre (DIFC). He also advised the UK government and market participants on legal and regulatory issues arising from the UK’s withdrawal from the European Union.

    In Chambers UK, clients state that “Barney’s depth of knowledge in financial services and his understanding of the complex foreign policy matters is key to his tactical advice”, and that he has “great institutional knowledge and experience”.

    Legal 500 notes that Barney is “highly pragmatic and approachable with the ability to take a very international view, drawing on deep and broad range of transaction experience” with one client commenting that he is “one of the most astute lawyers I have worked with in 30 years of banking. He has a very detailed approach to issues and always creatively finds solutions”.
