Financial services investigations and enforcement matters place firms and individuals under intense regulatory, commercial, and reputational pressure. We advise financial institutions, boards, senior management, and individuals on internal, regulatory and enforcement investigations, helping clients manage risk, respond proportionately to regulatory concerns and, where possible, avoid formal enforcement action.
Our lawyers regularly conduct and advise financial services firms on investigations arising from suspected regulatory breaches, market conduct issues, whistleblowing allegations, and cultural concerns. We are particularly well-known for advising clients facing scrutiny from the UK Financial Conduct Authority (FCA), the Prudential Regulation Authority (PRA), and overseas regulators and prosecutors.
We have led some of the most sensitive and high‑profile investigations in the financial services space in recent years, working for organisations including banks, hedge funds, and asset managers. We combine deep regulatory expertise with practical experience of regulator engagement and internal governance, including cross‑border and multi‑regulator matters.
Our team includes former regulators and criminal prosecution specialists, giving us valuable insight into how regulators approach investigations, enforcement action and interventions. This allows us to advise clients strategically from the earliest stages - whether responding to a regulatory enquiry, conducting internal investigations, making regulatory notifications, or preparing for potential enforcement action.
Where enforcement action cannot be avoided, we are experienced in defending clients before the FCA’s Regulatory Decisions Committee, the PRA’s Enforcement Decision Making Committee, and on appeals to the Upper Tribunal and other fora. We also provide seamless support where criminal investigations are pursued alongside regulatory action.
We can help with:
Investigating whistleblower allegations from the global head of surveillance at a major investment bank related to the implementation of the Market Abuse Regulation
Running an internal investigation for a hedge fund manager firm into suspected spoofing market manipulation by a trader
Running an internal investigation and accountability review for a bank regarding process failures in handling suspicious transaction alerts and consequent late filing of Suspicious Activity Reports
Conducting several cultural investigations for a global investment bank, including into allegations of institutional racism
Investigating bullying and non-financial misconduct allegations against two of the most senior UK bankers at a US headquartered global investment bank
