Tonica State Bank was established in 1914 with the concept of being a full service bank focusing on customer service. In 1983, Tonica State Bank acquired The Farmers State Bank of Lostant. In 1988, the names of the banks changed to reflect the unified financial presence and were named Illini State Bank. In 1992, Illini State Bank built a new facility on South Columbia Ave in Oglesby. In 1998, the Oglesby facility doubled in size to accommodate increasing growth and to better serve our customers. In 2014 Illini Investment Services was developed to further enhance our full service pledge.Then in 2017, we opened up a Loan Production Office located in Yorkville, IL, to expand our footprint and take further steps in growing our Bank.
After over 100 years in the area, Illini State Bank remains locally owned and operated. All decisions are made by management and a board of directors comprised of local individuals. It is because of the integrity, astute business decisions, and support of our many loyal customers that ISB has continued to be a financially sound bank here to support our communities. Our stability is proven by our 4 locations, our growth to now over $150 million in total assets, and a consistent 5-star bank ranking by Bauer Financials for over 30 years.
