What Drove the Early Growth of Old National Bank?
The Early Growth and Expansion of Old National Bank began after the National Banking Act of 1863, when the institution reorganized to align with the federal system and finance industrialization along the Ohio River, setting the stage for multi-state growth.
Following the National Banking Act, the bank reorganized as Evansville National Bank in 1863, initiating the Old National Bank history by supporting river-region industry and expanding beyond local retail banking.
In 1883 the institution secured a new charter and adopted the Old National Bank name to signal seniority; by the early 1900s it was the leading bank in Southern Indiana, moving into a landmark 1916 headquarters.
Responding to late-1970s deregulation, the company formed Old National Bancorp in 1982, enabling acquisitions across Indiana and Kentucky and initiating a documented Old National Bank timeline of consolidation.
During the 1990s and 2000s Old National expanded into Indianapolis, Illinois and Michigan, shifting loan exposure from agriculture and manufacturing toward professional services and healthcare to reduce concentration risk.
The 2014 United Bancorp and 2016 Anchor BanCorp Wisconsin deals increased presence in the upper Midwest; the 2018 KleinBank acquisition added Minnesota, transforming Old National into a multi-state bank with total assets rising above $20 billion by 2019.
In the 2010s the bank expanded wealth management and insurance, increasing noninterest income to help stabilize earnings during low-rate periods; fee-based services contributed materially to revenue diversification by mid-2010s.
