To make the kind of profit they make today, they'd have to charge you the interest they charge on loans today. My mortgage is 2.35%. Are you willing to watch your money disappear at that rate? I don't know that I am, but I'd never considered it before.

But considering that a lot of costs could be removed by cutting out the lending aspect of the bank business, wouldn’t this % become significantly lower? I imagine a good chunk of a bank’s budget is spent on loan management, risk assessment, marketing, etc.

You should also add the cost to pay more to the guys in the doors with the guns.

A usual bank has only some cash for the day, and a lot of paperwork that is important for the bank but worthless for everyone else.

But a 100% reserve bank must store all the money like Scrooge McDuck so it will be a juicy targets for thieves and you must add much more security guards, something like Fort Knox.
