The core idea
High-quality government bonds often benefit during recessions when markets expect lower inflation and monetary easing, but corporate bonds can face wider credit spreads as default risk rises.
What is happening underneath
The result is a split between interest-rate risk and credit risk. Treasury yields may fall at the same time that lower-quality corporate borrowing costs rise.
How investors should read it
The type of bond matters more than the word 'bond' itself.
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.
