Oxford University Press Market Abuse Regulation

The fourth edition of Market Abuse Regulation provides a timely and authoritative examination of the laws, regulatory frameworks, and enforcement practices designed to protect the integrity of global financial markets. Building on the success of the previous editions, this thoroughly revised volume offers clear, practical guidance on the prevention, detection, and prosecution of insider dealing, market manipulation, fraud, money laundering, and related forms of financial misconduct. Since the third edition appeared in 2019, financial markets have undergone dramatic transformation. Rapid digitalization, accelerating internationalization, proliferating online trading environments, and the emergence of digital assets have fundamentally reshaped how market abuse occurs-and how it must be regulated. This new edition reflects these developments with substantial updates on cryptocurrency and other digital asset regimes, high-speed and algorithmic trading, and the growing regulatory challenges posed by quantum computing, artificial intelligence, and automated market-surveillance technologies. This new edition offers expanded coverage of post-Brexit divergence between UK and EU regulatory models, including detailed treatment of new legislation, rulemaking, and enforcement strategy in the UK, EU, and United States, as well as comparative guidance on emerging regimes in other major jurisdictions. It provides up-to-date analysis of significant recent cases, new international market-manipulation rules, revised insider dealing laws, and high-profile incidents—such as unauthorized electronic access to confidential central-bank communications—that have shaped the modern understanding of market integrity. Market Abuse Regulation remains an essential resource for legal practitioners, compliance professionals, regulators, financial institutions, and academics. With its comprehensive coverage of both foundational principles and cutting-edge issues, the fourth edition equips readers to navigate an increasingly complex regulatory landscape and to understand the evolving risks that confront contemporary financial markets.
