Polish bank lobby says EU's FX loan ruling may cost them at least $15 billion

WARSAW (Reuters) - Polish banking lobby ZBP President Zdzislaw Pietraszkiewicz said the top European Union court's Thursday ruling on Swiss franc-denominated mortgages may cost lenders in Poland at least 60 billion zloty (£12.20 billion).

"There are no grounds to change our assessments and calculations at this stage, although we share the opinion that these costs would be spread over a certain time," Pietraszkiewicz told reporters when asked about the estimate.
