A Long Duration Fund is a category of debt mutual fund that invests in long-term fixed-income securities such as government bonds and high-quality corporate debt. These funds maintain a Macaulay duration of more than 7 years, making them highly responsive to interest rate movements.

They are best suited for investors with a long investment horizon who are comfortable with short-term volatility in exchange for higher return potential.

Long Duration Funds can deliver strong capital appreciation during periods of falling interest rates. Because bond prices rise when interest rates decline, these funds often outperform other debt categories in favorable rate cycles.

2. High interest rate sensitivity
