Polish authorities say they are working to find a solution to help the more than 500,000 Poles who hold Swiss franc loans, the payments of which are spiking after a recent surge in the franc.

Officials described details of the plan Wednesday after protesters in several cities rallied over the weekend to demand relief from loans whose value has in some cases doubled in the past seven years. It's turning into a pressing matter for the government ahead of parliamentary elections this year.

The Economy Ministry said its proposals include a three-year suspension on loan repayments in case the franc appreciates even further.

Finance Minister Mateusz Szczurek said the government is pushing banks to take "pro-consumer" steps to help clients with the Swiss franc loans.
