Banks run on interests and for that reason their are also after the charges the get from the customers and even though their have a stable coins, their interest generation and operations that generate the interest their could pay to customer holding those banks stable coins can't be compared to that of an exchange.
Take for example, how many Banks can generate the daily trading and staking and other Centralized exchange like binance volumes and cap.
In my country, there are banks that generate interest also.
I do not know of United States, the fintechs in my country can give as high as 20% up to certain amount, and 9 to 10% if that amount is exceeded.
There is even one with premium features in a way that you can save up to certain amount for 25 days and earn up to 36%>
The commercial banks should try and step up.
I think you are right though because commercial banks here are frustrating, although most people are using the account that have no yikes and the name will be the one that deducting customers money instead and call it maintenance charges.
