29 May 2026   |   New York

Contacts

KBRA assigns a long-term rating of AA+ with a Stable Outlook to the State of Illinois (the "State"), Build Illinois Bonds (Sales Tax Revenue Bonds), Junior Obligation Series A and B of June 2026 (the "Junior Bonds"). KBRA additionally affirms the long-term rating of AA+ with a Stable Outlook for the State's outstanding parity Junior Obligation Build Illinois Bonds.

Key Credit Considerations

The rating actions were because of the following key credit considerations:

Credit Positives

  • Security provisions are strong and include a priority lien on State sales tax revenues (after debt service payments on the Senior Obligation Build Illinois Bonds), a continuing appropriation requirement, and strong non-impairment language.
  • Junior Bonds’ additional bonds test (ABT) requires 10.2x coverage of MADS on combined debt outstanding, limiting the potential to overleverage.
  • The statewide sales tax base is expansive and diverse, highlighted by combined lien debt service coverage of 30.0x or higher for the past five fiscal years.

Credit Challenges

  • Build Illinois Bonds are secured by sales tax revenues, which can at times be adversely affected by economic factors, although the strong coverage levels and highly restrictive ABT are important mitigants.

Rating Sensitivities

For Upgrade

  • Accelerated, sustained growth in pledged revenue collections, coupled with manageable debt levels.

For Downgrade

  • While unlikely, issuance of Senior and Junior Bonds up to their respective ABTs, coupled with a catastrophic economic downturn that leads to a lasting, significant reduction in sales tax revenues.
