Do you have inflation protected bonds? In the USA you can buy I-Bonds (max $10k/year per person) that pay interest at the current inflation rate.
But what is considered “safe” really has a lot to do with your timeline. How soon do you want to access the money? If it’s in tears then index funds are likely a good buy today.
Poland offers something similar, but with a twist. On the plus side, the amount you can buy is unlimited. However, interest rate is fixed in the first year, at 7% (which is a far cry from 17.9% inflation). From the year two the interest rate is inflation rate + 1% premium. You can buy either 4 or 10 year bonds.
