About this list

Deposits are those held at each institution's offices in Montana as of June 30, 2026, from the FDIC Summary of Deposits, whatever state the bank is headquartered in. Market share is the institution's deposits divided by all deposits in Montana. Change from 2025 compares the same institution's Montana deposits and includes deposits that moved through mergers and branch sales; a dash means the institution had no offices here a year earlier. For banks headquartered in the state, see the Montana bank directory.
