Why Chinese investors are reviewing bond portfolios as AAA ratings come under scrutiny

China's financial watchdogs are tightening credit standards, prompting investors to re-evaluate their bond holdings for potential downgrades. This move aims to curb the unusually high number of top-rated AAA issuers, a situation exposed by recent corporate defaults. The People's Bank of China is reportedly introducing new metrics, potentially impacting issuers with wider yield spreads. This scrutiny could shake up the domestic bond market and test its recent rally.
