The legitimacy or illegitimacy of information exchanges between competitors remains a topical debate with regard to EU competition law and policy. This book reexamines the issue in the retail financial services sector, focusing on the peculiar problems that it poses for EU market integration, consumer policy and protection and the intersection with fundamental rights. It analyzes and reflects on the relevant case law and guidelines offered by the corresponding European authorities, providing a critique of the current approach and advancing the proposition that information markets themselves need attention, in addition to the markets that they serve. The book also advances new perspectives on cases in which consumers’ personal information is involved in the exchange, recognizing the inevitable interaction between EU competition law, the interests and protection of consumers and personal data protection. It suggests that the status quo under competition law is unsatisfactorily short sighted and that the EU should take a holistic approach (including information markets) to the analysis of competition law, reflecting consumer protection and fundamental rights aspects in the assessment.
