> safeguard your money for free. I'm stating the obvious here, but they never did keep the money for free. They used deposits as leverage for loans and received 100% of the interest as payment for keeping that money. Even then, for the longest time a lot of banks didn't have a "free" tier account like they do today so they were double dipping so to say. Negative interest rates aren't a new thing though. I'm more interested in where modern monetary theory will end up taking us and if that will make negative interest rates more common. It seems like a lot of people want to go in that direction. I don't know enough about it yet to know if that's good or bad.
