The core idea
Short-term government yields usually rise when markets expect higher central-bank policy rates or expect existing restrictive policy to persist for longer.
What is happening underneath
They can also move because of money-market conditions, bill supply and technical funding factors.
How investors should read it
The closer a security is to the policy horizon, the stronger the connection to expected central-bank rates tends to be.
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.
