Dynamic bond funds are mutual funds that mainly invest in debt securities such as government bonds, corporate bonds or money market instruments. They can adjust the portfolio across various maturities.

Under SEBI's framework, this fund is now called Dynamic Term Funds and is defined as an open-ended debt scheme that invests across durations. Unlike short-duration, medium-duration or long-duration funds, it does not have one fixed Macaulay duration range.

These funds can hold shorter-duration securities when rates are expected to rise and increase exposure to longer-duration securities when rates are expected to fall. The fund manager can change the holdings depending on what is happening in the interest-rate market.

A dynamic bond scheme can change its positioning, but it cannot completely remove interest-rate risk.

These schemes can suit you if:

• You want a fund that can change its duration: A dynamic bond scheme is not tied to a 3-year, 5-year or 10-year duration. The manager can alter the maturity profile as market conditions change.
• You have a longer investment horizon: The fund's portfolio has interest-rate exposure. Giving your investment more time can make short-term NAV movements easier to handle.
• You don't want to switch debt categories yourself: Instead of moving manually between short-duration funds and long-duration funds, you are giving the fund manager the charge to adjust the portfolio.
• You accept that the fund manager's decisions can go wrong: This flexibility is useful only if the manager makes sensible calls. A wrong view on interest rates can hurt returns.

Unlike other debt funds, dynamic bond funds work slightly differently. In this scheme, the fund manager decides how much interest-rate sensitivity the portfolio should carry.

Suppose market conditions suggest that interest rates may fall. The manager could increase exposure to longer-duration bonds. If rates actually fall, those bonds may rise and support the fund's NAV. If the manager expects rates to rise, the portfolio can be shifted towards shorter-duration securities. This can reduce the impact of rising rates.

Let's consider a scenario to understand how it affects your investment. Imagine you invest ₹10,000 at a NAV of ₹20. You receive 500 units. The fund manager later increases the portfolio's duration. Bond prices rise as market yields fall, and the NAV moves to ₹20.80. Your investment is now worth ₹10,400 (500 units x ₹20.80).

But the call can go wrong. If the rates rise instead, longer-duration bonds can lose value. Suppose the NAV falls to ₹19.40. Your 500 units would then be worth ₹9,700.

• Freedom to move across maturities: Unlike fixed-duration funds, dynamic bond funds can move across the maturity spectrum, giving the manager more room to respond to changing conditions.
• No need to time the debt categories yourself: You don't have to decide when to move from one debt fund to another depending on the market conditions. The scheme manager makes those portfolio decisions.
• Useful when the interest-rate view is uncertain: When it is difficult to know whether rates will move up or down, a flexible mandate can be useful. The manager can change the portfolio instead of being locked into one duration bucket.
• Flexibility to position for different rate cycles: The manager can increase duration when falling rates look likely and reduce it when rising rates become a concern. This creates the possibility of benefiting from different parts of the rate cycle.

• The manager can get the call wrong: If the fund increases duration expecting falling rates and rates rise instead, the portfolio can take a hit.
• Interest rate risk can be high: Some dynamic bond mutual funds can take substantial duration exposure. This can increase the interest rate risk. SEBI categorises these funds as carrying relatively high interest-rate risk.
• The strategy can lag even when the idea sounds good: Changing duration at the right time is difficult. Many dynamic bond schemes may struggle to consistently benefit from its rate-timing flexibility.
• Returns can be less predictable: The fund's duration, bond yields, credit spreads and portfolio decisions can all change. This makes the return pattern harder to predict than that of a simpler debt strategy.

These three categories can all be used for debt exposure, but their portfolios are built differently. Here's a quick comparison:

If your preference is to have a more defined duration, you can consider short-duration funds, medium-duration funds or long-duration funds, depending on your investment horizon and risk tolerance.

When looking for the best dynamic bond mutual funds, don't judge the scheme only by its latest return. Look for other factors too, such as:

• Compare performance across a full rate cycle: One good year is not enough. Check 3-year and 5-year performance along with rolling returns to see how the fund behaved through different market conditions.
• Check what the fund actually owns: Look at government securities, corporate bond credit ratings and the largest issuers. Two dynamic term funds can take very different levels of credit risk.
• Look at the manager's decisions, not just the final return: A fund may have delivered a good return because of one favourable rate movement. Understanding how duration changed can tell you more about the strategy.
• Compare against simpler debt schemes: Check how the fund has performed against short-duration funds or other relevant debt categories. The extra flexibility should be evaluated against the additional active-management risk.
• Check costs: Compare expense ratios, especially when two schemes have similar portfolios.
• Read the riskometer and scheme documents: The riskometer gives you a quick view of the scheme's overall risk. The portfolio and scheme documents provide more details.
• Check exit load rules: If you may need the money early, know whether an exit load applies before investing.

The best dynamic bond funds for you may not necessarily be the ones that are best for others. Always look for a scheme whose strategy and portfolio make sense for your investment horizon.

Once you decide to invest in a dynamic bond fund, you can set up a SIP on Millions in minutes:

• Install the Millions app from the Play Store or App Store.
• Register using your mobile number and complete the KYC.
• In the mutual funds section, find a dynamic bond fund that matches your requirements.
• Select SIP, then choose daily, weekly, or monthly investing.
• Enter your amount and preferred date, then complete the payment.

That is all it takes to start a SIP! With dynamic bond funds, regularly investing is only one part of the decision. The other important part is being comfortable with the portfolio's changing durations. If you prefer a more defined strategy, you can consider corporate bond funds, gilt funds or credit risk funds. For a more balanced portfolio, there are hybrid funds or index funds that you can explore.
