The role of credit risk in recent global corporate bond valuations

Notwithstanding the recent pick-up in corporate spreads in some markets, global corporate bond prices stand close to historical highs amid relatively low credit risk premia, particularly in lower-rated segments. At the same time, the COVID‑19 pandemic has increased the vulnerability and indebtedness of many firms around the world, with corporate credit ratings remaining below pre‑pandemic levels and some firms exhibiting relatively weak profitability. The model-based valuation analysis presented in this box suggests that the strong overall decline in global corporate bond spreads since the peak of the pandemic has been only partly driven by the market’s assessment of improving credit quality and could, to a large extent, be related to the strength of investors’ risk appetite. Based on analysis of bond-level valuations in the US corporate market, the box also shows that market-wide risk-off shocks have the potential to significantly increase corporate spreads and expected default probabilities, particularly for the weakest firms.
