I guess governments are doing the same in my country as well but banks are not.
In my country, banks are also into a practice of discounting something after some repayment but that never will impact the whole business in negative but some 1% or 2% discount in total interest revenue. For tier-1 and tier-2 countries, debit may remain as part of asset but for the rest of world, it would never be an option when considering against populations.
In my country both the government and the banks offer a negative interest rate. This means that you have to pay money for them, for them to accept my money as a loan. This happened because many people want to leave their money with banks or the government and they want to get paid for the security they provide. This doesn't even include inflation, which makes it even worse. The only real alternative is to buy stocks or crypto currencies.
