Lead regulator:
Commission de Surveillance du Secteur Financier (CSSF)
Key law:

Last updated:

Luxembourg's lending sector is strictly regulated, with the CSSF supervising credit institutions and investment firms under the Capital Requirements Directive (CRD) and Regulation (CRR). The regime enforces borrower-based measures, including Loan-to-Value limits for residential mortgages, and mandates robust loan origination and monitoring standards aligned with EBA guidelines. Consumer credit for residential property is governed by specific transposition of EU Directive 2014/17/EU, requiring adherence to the Consumer Code and CSSF circulars. Non-performing exposure management and semi-annual data reporting on real estate indicators are also key supervisory focuses.
