An industrial revenue bond is issued by a public authority for a private industrial project, with repayment usually tied to borrower or project revenues.
An industrial revenue bond (IRB) is a municipal or authority-issued bond used to finance a private industrial, manufacturing, or economic-development project, with repayment usually tied to payments from the private borrower or project rather than broad tax backing. IRBs are often discussed alongside Industrial Development Bonds and Private Activity Bonds.
A state or local issuer sells bonds and lends or leases the proceeds to a private business for an eligible facility. The borrower makes payments that are used to pay bondholders. The structure can support economic development, but it also concentrates credit risk in the private borrower and project.
Because tax status and repayment support vary, the phrase “industrial revenue bond” should not be treated as a complete credit description. The official statement, loan agreement, lease, guaranty, letter of credit, and tax documents determine the real risk.
| Feature | Industrial Revenue Bond | Industrial Development Bond |
|---|---|---|
| Common use | Broad label for revenue bonds tied to private industrial projects. | Often used for economic-development or manufacturing-focused private activity bond programs. |
| Repayment source | Borrower, project, lease, loan, or credit support. | Similar, but program rules may emphasize eligible development uses. |
| Main investor risk | Private borrower credit and project economics. | Private borrower credit, eligibility, tax compliance, and program limits. |
| Main document to review | Official statement, loan or lease agreement, security documents, and tax disclosure. | Same, plus program eligibility and volume-cap or tax-rule requirements when applicable. |
A development authority issues bonds to finance equipment for a manufacturing facility. The business leases the facility and makes payments that service the bonds. If the company weakens financially or the facility becomes uneconomic, the bond can suffer even though the issuer is a public authority.
