A Decade of OECD Competition Trends, Data and Insights

This OECD report examines how competition enforcement has evolved globally over the past decade, drawing on data from 66 jurisdictions between 2015 and 2024. It highlights shifting priorities in merger control, antitrust enforcement, and market studies as authorities respond to digitalisation, economic shocks, and changing market dynamics. The findings show a decline in overall enforcement activity alongside increased scrutiny of mergers and growing attention to technology-driven markets. Together, the data offer a clearer picture of how competition policy is adapting to modern economic and regulatory challenges.
