Oklahoma sits at a unique intersection of energy sector banking and Native American financial sovereignty — the state is home to 39 federally recognized tribes, many of which operate their own financial institutions, creating a banking landscape unlike any other US state.
Oklahoma City has emerged as a midsize financial hub anchored by MidFirst Bank (the largest privately held US bank) and the BancFirst network. The energy sector dominates commercial banking, with oil and gas companies requiring regular large wire transfers that make Oklahoma one of the highest per-capita wire transaction states in the country.
