The core idea
A rate cut directly lowers the central bank's policy setting and usually pulls very short-term market rates lower.
What is happening underneath
Longer-term yields may fall, remain stable or rise depending on what the cut implies for future inflation, growth and policy.
How investors should read it
Risk assets and credit spreads can also respond differently depending on whether the cut is viewed as preventive or recessionary.
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.
