The core idea
Corporate bonds can face wider credit spreads during recessions because weaker revenues and tighter financing conditions increase perceived default and downgrade risk.
What is happening underneath
High-quality bonds may still benefit from falling government yields, partially offsetting spread widening.
How investors should read it
Lower-quality credit is usually more exposed to the deterioration in the business cycle.
The same market move can carry different information depending on which maturity, issuer and risk premium is changing. Read the question together with the underlying concepts rather than treating one price move as a universal signal.
