Banks are listed by the headquarters reported to the FDIC, ordered by total branch-assigned deposits, largest first. In-state figures are deposits assigned to branches located in Montana; the Outside column is the remainder of the institution’s footprint. An institution headquartered in Montana may operate branches in other states, and banks headquartered elsewhere may operate here. This directory covers the 3,520 FDIC-insured institutions reporting at least one branch in the 1,523 counties within a Combined or Metropolitan Statistical Area, per the FDIC Summary of Deposits, June 30, 2025. It is not a census of every U.S. institution. Deposits shown are total branch-assigned deposits across every county where the institution reports a branch. See the methodology for how each figure is built, or the disclaimer for how this data should, and should not, be read.
