Which mutual funds are the most vulnerable to prepayment risk?

Prepayment risk tends to rise in debt funds that hold securitised debt papers (like mortgage-backed or retail loan-backed pass-through certificates), callable bonds, and structured credit products. Gilt funds and schemes mainly holding government securities usually keep a fairly low exposure in normal market conditions.

What is the relationship between prepayment risk and interest rate risk?

Interest rate risk occurs when bond prices are affected by changes in market interest rates, and prepayment risk concerns the earlier repayment of the principal. They both have an impact on returns, but one of the main issues that characterises prepayment risk is reinvestment problems.

Is it possible to have a loss for investors through prepayment risk?

Prepayment risk typically reduces expected returns rather than causing direct capital loss, though it may indirectly affect NAV over time due to lower reinvestment income. In case prepayments are done in the face of falling interest rate conditions, reinvestment at lower yields may reduce the fund’s ability to generate income.

Prepayment Risk in Debt Mutual Funds

Debt mutual funds may sometimes repay the principal before maturity, a scenario known as prepayment risk. This matters more for funds that hold callable securities or securitised debt instruments and is important when reviewing fixed-income investments overall.

What is Prepayment Risk?

Prepayment risk refers to the potential early repayment of principal of a debt security. This affects the investors when the principal is repaid before the maturity date. The investors then reinvest in lower interest rates. It is a risk that holds financial instruments like securitised debt, callable corporate bonds and structured debt products.

How Prepayment Risk Affects Debt Mutual Funds

Prepayment risk can change the anticipated cash flows and affect both income generation and the valuation of the portfolio. It typically increases when interest rates decline, as borrowers refinance their loans at lower rates.

Impact on Returns

mutual fund categories:

Gilt Funds: Gilt funds are funds with lower prepayment risk. They typically invest in government securities, which generally do not have embedded call options.
Corporate Bond Funds: The level of prepayment risk depends on the proportion of callable bonds, securitised debt instruments, or structured debt securities within the portfolio.
Credit Risk Funds: Exposure to prepayment risk is influenced by the portfolio's composition, particularly when it includes callable corporate bonds or structured debt securities.

Fund managers take into account the prepayment assumptions while constructing portfolios. The securities that have higher prepayment risks offer higher yields to compensate the investors for the extra risk.

Strategies for Managing Prepayment Risk

Mutual fund houses reduce the prepayment risk in several ways:

Diversification of portfolio using securities that have varying prepayment characteristics.
Examination of past prepayment patterns and other indicators of the economy.
Selecting securities with call protection features, lock-in periods, or prepayment penalties.

Final Take

Prepayment risk is an inherent aspect of certain debt instruments and can influence mutual fund performance. Understanding this risk allows investors to make a more informed evaluation of debt mutual funds. The Securities and Exchange Board of India (SEBI) states that portfolio transparency and scheme documents must include information on exposure to callable or structured securities, so investors can assess prepayment risk.
