The core idea
The bond market can signal expectations about growth, inflation, monetary policy, credit risk and liquidity through the level and shape of yields and spreads.
What is happening underneath
No single yield provides the whole message.
How investors should read it
A useful reading combines the yield curve, real yields, inflation compensation, credit spreads and funding conditions.
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.
