Merchants National Corporation

Merchants National Corporation (MNC) was an Indianapolis-based statewide bank holding company that was one of the largest Indiana-based financial institutions at the time it was acquired by Ohio-based National City Corporation in 1992. Its primary subsidiary was the Indianapolis-based Merchants National Bank and Trust Company, which had been founded in 1865.

From the mid-1950s through the late 1980s, Merchants National Bank and Trust, American Fletcher National Bank, and Indiana National Bank, were the three largest banks in Indianapolis. Their holding companies—Merchants National Corporation, American Fletcher Corporation, and Indiana National Corporation (later named INB Financial Corporation)—were the three largest bank holding companies in the state.
