The 30 insured institutions with a branch presence in this market, per the FDIC Summary of Deposits, June 30, 2026. Five-year change compares the same institution’s deposits in 2021 and 2026. Institutions are tracked by FDIC certificate number, and where an institution acquired another bank, the acquired bank’s prior deposits are folded into the baseline so the change reflects the combined, continuing franchise rather than reading as new. “No 2021 presence” means neither the institution nor a bank it later absorbed reported deposits in this market that year. Deposit figures are nominal and are not adjusted for inflation.
