Banks don’t decide when to originate new deposits, it’s driven by factors such as rates paid out and relationships with their clients. If a bank has a portfolio of CD’s on it’s books and projects a higher run off in the next 3-6 months, management has to decide how to replace that runoff (either by initiating some sort of promotion, paying higher than local market rates) or by seeking alternate sources of funding (Fed/FHLB borrowings, repos, brokered deposits). Or, if they already have sufficient liquidity, they can just let the run off take place. A bank won’t stop taking in deposits because they’re pretty hard to get in the first place. Usually, they will hold excess deposits in liquid investments like Treasuries or Agency MBS until loan demand is available to leverage their deposit base. The ideal situation would have all customers holding their deposits in a low cost product, like a checking or money market account for an indefinite amount of time. But that’s rarely the case because depositors have to pay their bills, food, etc. What they really don’t like, and have to model, are the customers like me, who won’t renew their CD’s or pull out their checking balances because the bank down the street offers a better product.
