Would you consider IB for saving ~100K euros compared to saving accounts or fix term deposits in Swiss Banks?
Current interest rate (~3.4%) is much higher than Swiss Banks offerings.
On the other hand the credit rating is lower than systemic Swiss banks (e.g. ZKB, Postfinance).
I believe the mother company has a credit rating of BBB+ while the broker has a rating of A-. However, I am uncertain about which one has a greater impact on the likelihood of going bankrupt or losing cash.
