This working paper outlines the technical and incentive dynamics for a proposed new sovereign debt instrument designed for countries with high country risk premiums, where this risk is, ceteris paribus, correlated with the quality of present and future governance. We call this instrument a Governance-Linked Sovereign Bond (GLSB). The paper introduces the design of a GLSB and the formulaic method for deploying such an instrument in situations where country risk premiums might be correlated with governance-related actions. A specific illustrative model is used to demonstrate the practical applications of this debt instrument.
