The average life of a US bank deposit is ~4.5 years (varies by product type) The average life of a stablecoin deposit on a borrow-lend protocol is 50% decay rate by month 1. This should make intuitive sense: switching costs are higher between banks, and banks offer a wide range of adjacent services, while DeFi protocols are usually one-trick ponies. That bundle of services, combined with ease of transacting with the balance, gives bank deposits a premium - users demand very little interest. It should be top of mind to all borrow-lend protocols how to expand their offerings beyond overnight, overcollateralized lending to build a premium on their own deposits. It should also be obvious that US banks and DeFi/stablecoins are not substitutes
