Stockman Bank is the only Montana bank named to Forbes’ World’s Best Banks list (2022–2026). First Interstate BancSystem, headquartered in Billings, is the largest bank holding company based in Montana. Glacier Bancorp, headquartered in Kalispell, operates Glacier Bank and multiple division banks across the state. National bank branch presence is relatively limited compared to more urban states — Wells Fargo has about 23 branches and U.S. Bank about 21, making regional banks the dominant force in Montana banking.
Checking, Savings, and CDs Explained
Most Montana banks offer the same core accounts:
- Checking — for everyday spending and direct deposit. Look for no monthly fee.
- Savings — for your emergency fund. Online banks pay the highest rates.
- Money market — a savings account with limited check-writing.
- CDs — lock money for a set term in exchange for a higher fixed rate.
A common setup for Montana residents is a no-fee checking account at a local bank plus a high-yield savings account at an online bank.
How Bank Sign-Up Bonuses Work in Montana
Banks pay cash bonuses — often $100 to $400 — to win new customers. To earn one you typically open a new checking or savings account, then meet a requirement such as receiving a set amount of direct deposit or keeping a minimum balance for a few months. The bonus is usually paid within 90 days. As long as you would open the account anyway, it is essentially free money. We track current offers open to Montana residents on our listings page.
