What is a Repayment Bond Guarantee?
A Repayment Bond Guarantee (RBG) is a credit-enhancement mechanism designed to secure infrastructure debt investments by providing a surety-backed repayment structure. These guarantees absorb credit risk, enabling project bonds to achieve enhanced credit ratings and attract institutional capital at lower financing costs.
By leveraging structured guarantees, RBGs bridge the gap between infrastructure project sponsors and institutional investors—creating a more liquid, risk-adjusted, and scalable investment environment.
Key Features:
Guaranteed principal & interest repayment in the event of issuer default
Enhanced credit ratings—reducing yield requirements for project bonds
Lower financing costs & improved capital efficiency
Applicable across infrastructure sectors—energy, transport, utilities, healthcare, and more
