U.S. Bank remains Greater Cincinnati's biggest bank by local deposits, but the gap between it and hometown rival Fifth Third Bank narrowed slightly over the past year, according to newly released federal data. The Federal Deposit Insurance Corporation's annual Summary of Deposits survey, published Tuesday, measures branch-level deposit balances at insured institutions as of June 30 each year, and this cycle's results show Greater Cincinnati's three largest banks all posting notable growth.
According to Local 12 News, Minneapolis-based U.S. Bank, which trades under the ticker USB, has a branch presence extending into Fort Mitchell and continues to sit atop the region's deposit rankings. The FDIC's broader survey framework provides the annual benchmark used to track local market movement.
The scale of U.S. Bank's local dominance shows up clearly in county-level figures. In Hamilton County, the core of Greater Cincinnati, total bank deposits reached $159.2 billion across 33 institutions as of mid-2025, with U.S. Bank commanding a 63.3% share, according to data compiled by The Executive Recruiter Group.
Fifth Third's National Leap Reshapes the Local Picture
Fifth Third Bancorp's position in that local rivalry comes against the backdrop of a major national transformation. The Cincinnati-headquartered bank completed a $10.9 billion merger with Comerica Incorporated on February 2, 2026, a deal that pushed it into the ranks of the ninth-largest bank in the country with roughly $294 billion in total assets, according to a statement from Fifth Third's investor relations office.
That deal expanded Fifth Third's retail footprint into 17 of the 20 fastest-growing U.S. metro areas, per the same statement. The bank's roots in the city run deep: it traces its lineage to the 1858 founding of the Bank of the Ohio Valley, later adopting its current name after Third National Bank and Fifth National Bank of Cincinnati merged in 1908, according to a history compiled by Companies History.
Other Cincinnati Banks Are Also Chasing Growth Through Deals
First Financial Bancorp reported its first-quarter 2026 financial results, according to a release distributed via PR Newswire. In July, the company announced an agreement to acquire Indiana-based Finward Bancorp, a move that would add 1.7 billion in deposits and 24 branches across Northwest Indiana and Chicago, per a statement from First Financial Bank.
Taken together, the acquisitions by Fifth Third and First Financial illustrate how aggressively Cincinnati-based regional banks are chasing deposit growth across Midwestern and Sunbelt corridors even as they compete for local market share at home.
How Cincinnati's Deposit Market Stacks Up Nationally
The Cincinnati tri-state metropolitan area spans Ohio, Kentucky and Indiana.
U.S. Bank's local dominance reflects its status as a national player.
All of this local jockeying happens under federal reporting requirements. The FDIC's annual Summary of Deposits data gives regulators and the public a tool for monitoring local market concentration. The annual release provides a barometer of which banks are winning — and losing — ground in markets like Greater Cincinnati.
