Account balances are privileged up to CHF 100’000 per pension fund member. In a bank bankruptcy they fall into the second rather than the third bankruptcy category.
Additionally, securities balances are even better off than account balances. Securities are not shown on the bank balance sheet. They are regulated as special assets and, unlike account balances, they do not fall into the bankruptcy assets of the bank. This means that your pension is as safe as possible with finpension Vested Benefits Foundation.
