In an interview on public television, Rogán said that, for a mortgage of HUF 6.5 mln taken out in Swiss francs in 2007, the value of the rate spread – the margin charged by the bank based on the exchange rate – would amount to HUF 323,000 (€1,030). He said the legal changes would mean banks would have to refund that money to borrowers. In the case of a unilaterally changed contract that is ruled unlawful, the law could save borrowers of such a loan as much as HUF 835,000, he added.
