信用评级质量对银行贷款合同的影响

主讲人 : 周凌 教授

The issuer-pay model of major credit rating agencies has long been criticized for its potential to create conflicts of interest and inflated ratings. We provide evidence that rating inflation affects the design of private loan contracts. We find that lenders are less likely to grant performance-sensitive debt indexed to credit ratings (rating-based PSD) when issuer-paid ratings are inflated. Furthermore, difference-in-differences analysis indicates that rating-based PSD is more likely after an exogenous shock that decreases the inflation of issuer-paid ratings. In response to rating inflation, the lender increases monitoring efforts by relying on performance covenants. Consistent with increased monitoring and renegotiation costs, interest spreads are higher for borrowers with inflated ratings. We further document an effect on other important contract terms. Our evidence is consistent with lenders adjusting different contract terms to compensate for monitoring deficiencies associated with inflated credit ratings.
