The Luxembourg Commission de Surveillance du Secteur Financier reminded firms that the transmission method for internalised settlement reporting under Central Securities Depositories Regulation (CSDR) Article 9 will change from 1 July 2025. From that date, reports will be collected exclusively via two specified submission methods and the CSSF noted that submissions through these channels will be free of charge. The CSSF also indicated it will communicate the opening dates for pre-production testing and provide a dedicated user guide.
