Laws, regulations and circulars

The CSSF ensures that the laws and regulations governing the various areas of the financial sector are enforced and observed.


The Circulars issued by the CSSF complement the regulatory framework. Through these Circulars, the CSSF clarifies the implementation modes of different legal provisions governing the supervised entities, publishes prudential rules relating to specific activities and gives recommendations regarding financial activities.


The regulatory framework of the Luxembourg financial sector has been developed under the co-ordination works of the European Union and the Group of Twenty. It complies with international standards on high-quality prudential processes.


The laws and regulations in force are regularly updated and available as pdf-files. All the repealed and outdated circulars since 1 January 1999 are also available.
