The Swiss government has frozen about $6.17 billion in Russian assets that are subject to sanctions, and this figure is likely to rise, Reuters reported.

This includes a number of properties in the cantons that have served as tourist resorts.

"Today, for the first time, I can give you an indication of the amount of frozen funds. To date, SECO has been notified of funds and assets totalling around 5.750 billion Swiss francs," said Erwin Bollinger, a senior official at the State Secretariat for Economic Affairs (SECO) agency overseeing sanctions.

Following new reports and potential additions to the EU sanctions lists, it is likely that this number will increase even more.

The Swiss banking lobby estimates that it holds up to $213 billion of Russian capital in its banks.

"The cited number of far over 5 billion francs relates to a snapshot in time," Bollinger noted. "With further reports coming in and potential additions to EU sanctions lists, which Switzerland would also assume, it is likely this number will rise further."
