Your friend Ed has a money market mutual fund account, automatic deposit of his paycheck into an interest-bearing checking account at the company credit union, and a CD from the local branch of a bank that advertises "coast-to-coast" banking. What is the benefit of "mixing and matching" financial institutions and their services?

Mixing and matching financial institutions and their services involves using services of different financial institutions. The benefits of doing this is to utilize their different lending and borrowing interest rates. One that has the lowest lending interest rate will be used to get credit and the one with the highest savings rate will be chosen for investments. Another benefit is to minimize fees, minimize risk of loss could there be a bank-run and to also enjoy the increase in flexibility that comes with managing money in different accounts.
