We investigate the nascent but fast-growing Chinese bond market and credit rating industry. We find Chinese bond ratings are informative and significantly correlated with bond offering yields. In addition, the Chinese bond investors distinguish ratings from different credit rating agencies (CRAs), demanding lower yields on bonds rated by global-partnered CRAs. However, the empirical results suggest that the rating scales used by Chinese CRAs are not comparable to those of international CRAs. Furthermore, Chinese CRAs have very broad rating scales and pool bonds with significantly different default risks into a single rating category, resulting in over 90% of bonds in only three rating categories.

Unique features and market frictions can lead to idiosyncratic pricing for some US Treasury securities. This study uses a linear programming (LP) model to measure aggregate idiosyncratic pricing of T-notes and T-bonds from 1980 to 2016. We document an average idiosyncratic pricing of $0.11 per $100 par, as compared to an average bid-ask spread of $0.08. Further, idiosyncratic pricing declined dramatically from the early 1980s to the 2010s. Empirical evidence suggests that the 1986 Tax Reform Act, increasing issue sizes and improving market liquidity contribute to the decline. At the individual security level, we identify factors contributing to and mitigating idiosyncratic pricing.
