How to view the credit risk
One example from the automotive sector is the large spread differential between Ford and Renault bonds with similar coupon and maturity.
Although the rating agencies assign approximately the same credit risk to both issuers, investors view the risk that is related to owning Ford bonds as significantly higher. It clearly outlines that Ford bonds have been much more volatile than Renault bonds between September 2003 and February 2004. When S&P put Ford on credit watch negative on October 21, 2003, spreads widened massively. Even if only very few investors feared a multiple notch downgrade of Ford from the then BBB rating, a 1 notch downgrade to BBB coupled with a negative outlook would have caused concerns about a later downgrade of Ford into high-yield. There were fears that the high-yield market would not be able to absorb the large volume of outstanding Ford bonds, and from a fundamental perspective that the company’s financing costs would rise, thus limiting the company’s financial flexibility massively. This example highlights that market technicals at least temporarily can be the dominant driver of credit spreads.
