The core idea
Tax cuts can raise bond yields when investors expect stronger demand, higher inflation, larger deficits or increased government issuance.
What is happening underneath
The effect is not automatic because tax policy can also alter long-run growth and fiscal credibility in different ways.
How investors should read it
Bond markets price the expected macro and financing consequences rather than the policy label 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.
