Non interest bearing deposit accounts are the gold standard for most banks in the current market. Rapid fed rate increases have put many banks in a position where their current loans have not yet ballooned and were written when the fed rate was sub 1%. This means that if banks want to continue making a profitable net interest margin they need to continue to have as many deposits as possible in non interest bearing accounts. The problem is that many banks are now capturing deposit accounts by offering 4% on savings accounts so some of those sedentary accounts are being moved out of the bank to accounts where they can make money. The key to stopping this runoff is to keep those funds in motion. If the merchant uses their account to run their business they are less likely to move them off the balance sheet.
