The core idea
Additional government spending can lift yields if markets expect stronger growth, higher inflation or more bond issuance.
What is happening underneath
During a weak economy, however, spending may improve growth without generating the same inflation or rate response.
How investors should read it
The starting economic regime determines how fiscal expansion reaches the yield curve.
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.
