The Mortgage Funding Adequacy Ratio (MFAR), announced by the MNB in June 2015 and required from 1 April, 2017, ensures the long-term financing of residential mortgage loans with mortgage-based funds in the banking system. According to the Mortgage Funding Adequacy Ratio (MFAR) regulation, the outstanding forint residential mortgage loan portfolio with a remaining maturity of more than 1 year must be financed in a specified proportion with long-term HUF funds raised with the collateral of residential mortgage loans. Currently, this minimum requirement is 25 percent.

The MNB regularly reviews the MFAR requirement regarding market developments and financial stability goals with the intention of deepening the mortgage bond market, strengthening and diversifying demand. In light of this, the indicator changed several times, which meant both level increases and changes in content, primarily affecting the quality characteristics of acceptable funds, as well as limiting cross-financing. Funds based on mortgage bonds and covered by mortgage loans can be considered a stable, long-term form of financing, the cost of funds being relatively low thanks to their favorable risk rating. In this way, credit institutions can reduce their balance sheet maturity differences under favorable conditions, and in addition to the increasingly widespread loans with longer interest periods, they can also mitigate their interest rate risk. This can have a positive effect on loan interest rates and mortgage lending as a whole.
