On 12 April 2019, the CSSF released its Circular letter 19/716
on the provision in Luxembourg of investment services or
performance of investment activities and ancillary services in
accordance with Article 32-1 of the law of 5 April 1993 on the
financial sector, as amended (the "LFS").
The purpose of this circular letter is to provide guidance
on the rules and restrictions which apply to third country
financial service providers when providing MiFID investment
services, activities and ancillary services to Luxembourg
clients.
Third country service providers are
service providers which are not established within the European
Economic Area, such as U.S., Swiss and Japanese service providers,
and in the future – provided no deal is reached with the EU
– UK service providers.
