Preface Over the past decade, competition enforcement has been shaped by a series of profoundmacroeconomicand market shifts. The COVID-19 pandemic disrupted supply chains and accelerated digitalisation; thereturn of inflation and rising interest rates have altered market dynamics and investment patterns; andgeopolitical tensions have introducednew complexities in global trade. At the same time, the emergenceof digital platforms, AI technologies and new business models has challenged traditional enforcement Understanding the direction and intensity of competition enforcement requires more than anecdotalevidence–it demands robust, systematic data. As a results-driven and evidence-based organisation, theOECD recognises that competition enforcement statistics provide an essential lens through which we canassess how competition policy is evolving, where enforcement is being prioritised and whether the tools at This edition of Competition Trends marks a significant milestone: ten years of data collected on competitionenforcementstatistics.Over the past decade,this dataset has become a valuable resource forunderstanding how competition policy is implemented across jurisdictions and over time. It allows us tomovebeyond case studies and empirical observations,offering a more comprehensive view ofenforcement trends, priorities and institutional evolution. While aggregate results may not fully reflectthe As the Chair of the OECD Competition Committee, I am honoured to contribute to this special edition.Looking ahead, I welcome the work that will be supported by this database, which stands as a strongexample of the OECD’s analytical role and of its contribution to fostering international co-operation amongcompetition authorities. Strengthening collaborative efforts and disseminating the use of shared evidence This year’s report reveals a mixed picture over the decade. Overall enforcement activity has declined,raising questions about whether this reflects a shift in priorities, resource pressures or changes in thenature and complexity of competition enforcement. In contrast, merger control activity has increased, 4 as a key instrument for improving understanding of how a sector operates and diagnosing competition As we interpret these trends, it is important to consider not only the volume of cases but also their strategicimpact. Enforcement remains a cornerstone of competition policy, but its effectiveness depends on the These trends underscore the importance of maintaining an agile, adaptable approach tocompetitionenforcement. As markets evolve–shaped by new technologies, globalisation and new business models–so too must our enforcement strategies. We hope this report supports informed reflection and dialogue Chair of the OECD Competition Committee Foreword This special edition of OECD Competition Trends presents unique insights into global competition trendsbased on a decade of data from66OECD and non-OECD jurisdictions.
