Supervision release 8 December 2017 – 68/2017

Reporting of 15% minimum risk weight on residential mortgage loans

On 26 June 2017, the Board of the Financial Supervisory Authority (FIN-FSA) made a conditional decision according to which the average risk weight on residential mortgage loans must be a minimum level of 15% for banks that have adopted the Internal Ratings Based Approach. On 21 August 2017, the European Commission decided not to raise any objection to the decision of the Board of the FIN-FSA, as a consequence of which the minimum risk weight level will enter into force on 1 January 2018.

Key aspects of the decision as well as information on the reporting of minimum risk weights

  • The minimum level is institution-specific, excluding institutions belonging to an amalgamation of deposit banks. In an amalgamation of deposit banks, the minimum level is calculated on a consolidated basis for the amalgamation as a whole.
  • The minimum level applies to residential mortgage loans defined in accordance with chapter 7a, section 3, subsection 2 of the Consumer Protection Act, where the housing unit acquired is located in Finland.
  • State-guaranteed loans are included in the above-mentioned loan portfolio.
  • The minimum level is calculated according to the average EAD-weighted risk weight.
  • Reporting takes place quarterly as csv-format data collection based on the COREP C 08.02 form.
  • The FIN-FSA will seek from both the Swedish Financial Supervisory Authority and the Danish Financial Supervisory Authority reciprocal recognition for the decision, which would apply to branches and cross-border loans.
  • The reporting regulations will be added to the FIN-FSA Regulations and Guidelines.
  • Before the reporting requirement begins, the draft Regulations and Guidelines will be sent on a public consultation round.
