Corporate bonds with implicit government guarantees

• We model an implicit government guarantee as a partial protection for corporate bonds issued by state-owned enterprises (SOEs) and present pervasive evidence of its existence in the Chinese corporate bond market. • The protection effect is stronger among poorly rated SOE bonds than for highly rated SOE bonds. • For newly issued corporate bonds, the average guarantee premium is 72 basis points (bps) for AAA bonds while it is 166 bps for AA- (lowest issuance rating) bonds. • We find the guarantee premiums are higher for bonds issued by central government sponsored SOEs and by issuers from strategically important sectors.
