On the 2nd of August the President's Office announced a new approach towards addressing the CHF-issue in Poland. Instead of forcing banks to convert CHF into PLN mortgages through a bill, now the proposed plan is to increase risk weights on FX mortgages.
"As of the cost of returning excessive spreads, the Office of the President mentioned a figure of PLN 3,6-4 bn. It seemed undervalued to me, taking into consideration previous KNF estimates as well as banks’ communications. It is more likely that the cost will amount to around PLN 7-8 bn" - explained Kamil Stolarski.
