Illinois Statutes Chapter 30. Finance § 225/1. Deposits

§ 1. Deposits. Any treasurer or other custodian of public funds may deposit such funds in a savings and loan association, savings bank, or State or national bank in this State, or deposit those funds into demand deposit accounts in accordance with Section 6.5 of the Public Funds Investment Act. 1 When such deposits become collected funds and are not needed for immediate disbursement, they shall be invested within 2 working days at prevailing rates or better. The treasurer or other custodian of public funds may require such bank, savings bank, or savings and loan association to deposit with him or her securities guaranteed by agencies and instrumentalities of the federal government equal in market value to the amount by which the funds deposited exceed the federally insured amount. Any treasurer or other custodian of public funds may accept as security for public funds deposited in such bank, savings bank, or savings and loan association any securities or other eligible collateral authorized by Sections 11 and 11.1 of the Deposit of State Moneys Act or Section 6 of the Public Funds Investment Act. Such treasurer or other custodian is authorized to enter into an agreement with any such bank, savings bank, or savings and loan association, with any federally insured financial institution or trust company, or with any agency of the U.S. government relating to the deposit of such securities. Any such treasurer or other custodian shall be discharged from responsibility for any funds for which securities are so deposited with him or her, and the funds for which securities are so deposited shall not be subject to any otherwise applicable limitation as to amount.

No bank, savings bank, or savings and loan association shall receive public funds as permitted by this Section, unless it has complied with the requirements established pursuant to Section 6 of the Public Funds Investment Act  2or is otherwise exempt from compliance as authorized by Section 6.5 of that Act.
