Unveiled by the European Commission on July 3rd, the proposed Regulation on key information documents (KID) for packaged retail investment products (PRIPs) represents a step forward in enhancing the protection of retail investors and advancing the single market for financial services. While acknowledging in this Commentary that the KID is a commendable effort, ECMI/CEPS researcher Mirzha de Manuel Aramendía observes that pre-contractual disclosure is just one of the pieces in the jigsaw puzzle of investor protection and regrets that other pieces, such as MiFID and the IMD, are not so ambitiously constructed.
