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.
