Overdraft fees. We discuss the four different fee types, their magnitudes, and how some bad banks are almost entirely reliant on overdrafts for profitability. We turn our attention to legislative action and the appropriate role for regulators, taking into consideration recent research showing that overdraft services can increase access to banking for low-income families and the unbanked. We wrap up with a look at some of the startups and banks that are innovating in the space and what to expect next week.
