Interest Rate Risk — Mutual Fund Term Explained

For debt funds: when interest rates rise, fund NAV falls. Funds with longer duration are most affected.

When interest rates rise, bond prices fall — and vice versa. This inverse relationship creates interest rate risk for debt fund investors.

During RBI rate hike cycles, long-duration gilt funds can fall significantly. During rate cut cycles, they can deliver equity-like returns.
