State Investments

Investing, protecting, and growing State dollars

Investing on behalf of Illinois

State legislators budget public monies that are collected, but that money is not spent all at once. As such, state agencies, boards and commissions require assistance managing their cash and investing all remaining funds in authorized investment vehicles. That's where the Office of the Illinois Treasurer steps in.


As the state's Chief Investment Officer and Chief Banking Officer, the Office of the Illinois Treasurer is responsible for receiving and safekeeping all public monies of the State, ensuring liquidity is available to meet the State's obligations, and investing remaining funds in appropriate instruments that obtain the best risk-adjusted returns.


State Investments, which are invested and managed by the Office of the Illinois Treasurer, total approximately $25 billion.
