Partisan conflict and corporate credit spreads: The role of political connection

This paper documents the positive impact of partisan conflict on corporate credit spreads for politically connected companies and industries. The effect is both economically meaningful and statistically significant, stands under an extensive set of control variables, and is stronger for speculative-grade bonds. Several approaches are adopted to resolve endogeneity issues and further establish causality. Partisan conflict affects corporate credit spreads through a discount rate channel, increases investors’ risk aversion, and leads to higher borrowing costs and widening credit spreads. Affected companies respond by reducing debt issuance and postponing investments until the conflict subsides.
