Switzerland has announced a stringent due diligence regime for its banks to reject accepting illicit funds from both existing and new customers. Swiss banks would also terminate relationships with existing clients who are found to have stashed illegal assets in their accounts. To fight the back money menace, Switzerland has already agreed to be part of a global automatic exchange of tax information framework. The latest move comes at a time when Switzerland is making public names, including that of Indians, among scores of foreign nationals with Swiss bank accounts, for being probed in their respective home countries.
