In this paper, we propose a solution to effectively reduce the credit and systemic risk inherent to this portfolio – the proposed model can be applied to other mortgage portfolios in trouble as well. The main element of our proposal is income-contingent repayment complemented with effective incen- tives to motivate debtors to repay their debt. We demonstrate that the proposed scheme is attractive for both the debtors and the lenders; therefore, contrary to some recent policy measures, in this case there is no need for direct state intervention to force modications to the existing legal contracts. In order to evaluate the possible effects, we simulated a realistic population of borrowers with different age, debt, loan-to-value, and income. Then we calculated the expected income paths, the repayments of the borrowers as well as the prot of the lenders on the basis of the non-performing FX mortgage portfolio. The results underpin that the proposed scheme creates signicant value added and, most importantly, that it can effectively reduce the vulnerability of the entire economy to future shocks.
