What is Old National Bank?

Old National Bank is one of the oldest financial institutions in the Midwest, founded in 1834 in Evansville, Indiana — originally established on a bend of the Ohio River to serve the region's growing commercial and agricultural economy. With over 190 years of continuous operation, Old National Bancorp (Nasdaq: ONB) is today headquartered in Evansville, Indiana, and ranked among the 40 largest commercial banks in the United States.

In 2022, Old National completed its merger with First Midwest Bank, significantly expanding its reach across the Midwest and Southeast. The combined institution now operates across 9 states — Indiana, Illinois, Iowa, Kentucky, Michigan, Minnesota, North Dakota, Tennessee, and Wisconsin — with approximately $72 billion in total assets and several hundred branch locations as of Q3 2025.

Old National's personal checking accounts come with a Debit Mastercard for everyday transactions, online purchases, and ATM access. The bank does not offer direct cryptocurrency trading, but allows customers to use their Mastercard debit card or ACH transfers on regulated third-party exchanges like CEX.IO.
