The Iowa Bankers Association was founded on June 22, 1887 by a group of 29 Iowa bankers. The association was formed to represent Iowa banks in front of Iowa legislature and to provide a way for individual bankers to gather and exchange ideas on the business of banking. It was the fourth state bankers association formed in the United States. IBA became the largest state banking association in the United States in 1905, with a membership of over 1,000 banks. By 1922, every bank in Iowa was a member of IBA, numbering 1,877 at the time. In 1906, IBA began to offer insurance products to rural banks, and in 1945 the organization began the Bankers Insurance Plan to provide health insurance to bank employees and officers. Iowa Bankers Insurance and Services (IBIS) became a separate entity in 1971. The Iowa Transfer System, now SHAZAM, was incorporated for the formation of a statewide switching system in 1975. In 1979, Iowa Bankers Mortgage Corporation was founded and as an affiliate company of IBA, provides secondary mortgage services to banks across Iowa. IBA Headquarters were established in downtown Des Moines in 1912 and were moved to Johnston in 2001. In 1898, the IBA Group System was established, which enabled regional groups of bankers to meet to discuss issues. In 1920, IBA partnered with Iowa State College (University) to provide an educational session entitled "Bankers Short Course." IBA is affiliated with the American Bankers Association and continues to work on the improvement of the banking industry and to serve bankers across the state of Iowa.
