Recommendation – Limits applicable to mortgage loans

The CNB regularly assesses mortgage loans and the overall situation on the mortgage market. Based on the information it gathers in the course of macroprudential policy-making and financial market supervision, it issues a Recommendation on the management of risks associated with the provision of retail loans secured by residential property (the “Recommendation”).

Relaxed credit standards, rapid growth in mortgage loans and rising property prices in an expansionary phase of the financial cycle may give rise to conditions for the accumulation of systemic risks in the financial sector.

The Recommendation contains a summary of recommended limits for selected credit ratios and a set of other rules, the observance of which, in the CNB’s opinion, constitutes a prudent approach when conditions on the financial market are taken into account.

The recommended limits relate mainly to the following ratios:

  • loan-to-value (LTV)
    The ratio of the loan to the value of collateral should not exceed 90%.
  • debt-to-income (DTI)
    Applicants’ total debt should not exceed nine times their net annual income.
  • debt service-to-income (DSTI)
    Applicants should spend no more than 45% of their monthly income on the monthly repayments of all their loans.

In its Recommendation,1 the European Systemic Risk Board (ESRB) mentions LTV, LTI (loan-to-income), DTI or DSTI requirements among the macroprudential instruments that national authorities can use to support financial stability on top of the instruments contained in CRD IV. The aim of these instruments is to eliminate feedback between growth in lending and property price growth.
