Paradoxically, the default state of fiat currency is deflation, because the primary means of money creation is debt. If inflation is 2% every year that means future debts must overshadow past debts. If you raise interest rates people stop borrowing money because it becomes too expensive. The interest rate itself acts as a productivity gate. "You must be this productive to obtain financing." If you stop borrowing money, then the only place for the money to go is to pay off debts, which contracts the money supply and you get deflation which is strong enough to counteract past inflation. The vast majority of dollars were "printed" this way.
