Interest rates in Bank in Bangladesh is below 5% now. In some Banks, it's 2%.
That's actually great if you compare it with ABN Amro bank, which has a negative interest. You need to pay the bank 0.5% for having your money deposited there:
Negative interest proves that your nation is doing great, it is not a bad thing. In turkey the interest rates in a bank is as high as 18% for example, that means if you put money in there, you would be making a lot of profit from interest, however that also means that you are losing soooo much of your moneys value as well, the inflation is nearly 40% but they are hiding it so that means you are losing money even with 18% interest rate.
Look at all the bad nations with bad inflation and you will find good interest rates, they are just there to make sure you do not turn your money into foreign currency, which people do anyway. All in all I would say that negative interest is awesome, because that means at least your nations economy is doing fine, and if you put your money into a business instead of interest, then you could make a bigger profit, or at least some profit instead of negative.
