The core idea
A bear steepener occurs when yields rise and longer-maturity yields rise more than shorter-maturity yields.
What is happening underneath
It can reflect higher long-run inflation expectations, increased sovereign issuance, stronger growth or a rising term premium.
How investors should read it
It is particularly important because long-duration assets can lose value even without a major change in the near-term policy rate.
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.
