Accrual and duration strategies respond differently to changing interest rates and can significantly impact your bond returns. Understand both approaches and position your portfolio better.
When markets turn uncertain, attention naturally shifts to the central bank’s policy stance, as any change in rates can directly influence your fixed income portfolio.
To navigate this, investors rely on specific fixed-income strategies. Two of the most widely used approaches are accrual and duration. While one focuses on earning a steady income, the other aims to benefit from interest rate movements.
In this blog, we break down both approaches, compare their roles, and help you understand where your focus should lie based on the evolving interest rate cycle.
What is an Accrual Strategy in Bonds?
The term “accrual” refers to the process of earning interest steadily over time as the bond’s coupon income accumulates. The emphasis here is on the regular income that builds up as you hold the bond.
An accrual strategy, therefore, is built around the same idea. Wherein, you invest in bonds with the intention of earning predictable coupon income and holding them through their tenure, rather than trying to benefit from short-term price fluctuations. The return here comes largely from interest earnings, not from market timing.
When Accrual Strategy Becomes Relevant for Investors
Accrual strategy becomes particularly relevant when interest rates are expected to remain stable or move within a narrow range. In such scenarios, the opportunity to earn from interest rate fluctuations is limited, making a steady income a more reliable source of return.
For instance, experts currently suggest that the RBI may hold rates steady in the near term, especially in the early part of FY 26–27 despite the West Asia conflict. In such a phase, trying to position for sharp interest rate movements may not add significant value.
Instead, an accrual approach allows you to lock in existing yields and earn predictable returns, without taking on unnecessary duration risk. Conversely, If you want a strategy that is able to perform better when the interest rate changes, you may want to know more about duration strategy.
What is Duration Strategy in Bonds?
In fixed income investing, duration measures how sensitive a bond’s price is relative to the changes in interest rates. It goes beyond time to maturity and captures how the present value of a bond’s cash flows responds to changes in interest rates. Simply put, a longer duration means greater sensitivity to interest rate changes.
A duration strategy is built around this sensitivity. Instead of focusing only on earning coupon income, you position your portfolio to benefit from interest rate movements. According to the inverse relationship between price and yield, when interest rates fall, bond prices rise. This impact is more pronounced in long-term bonds. This creates an opportunity to generate capital gains in addition to regular income.
How Interest Rate Cycles Impact Duration Strategy
The direction of interest rate cycles directly shapes the duration strategy. When interest rates are expected to decline, you typically increase your exposure to long-duration bonds to capture price appreciation. Even a small drop in rates can lead to a meaningful rise in bond prices, allowing you to realize capital gains.
On the other hand, when interest rates are expected to rise, long-duration bonds tend to fall more sharply in value. In such phases, an active duration strategy involves shifting toward “short-duration” or “ultra-short-duration” instruments to shield the portfolio from falling prices.
You actively adjust your portfolio duration based on your interest rate outlook, using rate cycles as an opportunity to enhance returns rather than just earn fixed income.
Now that you understand how duration strategy works in practice, it becomes easier to compare it with accrual strategy across key parameters.
Accrual vs Duration Investing: Key Differences
| Parameter | Accrual Strategy | Duration Strategy |
| Primary return driver | Returns are driven by coupon income accrual (carry) over time, with limited reliance on price movement | Returns are driven by mark-to-market (MTM) gains/losses due to changes in interest rates |
| Interest rate sensitivity | Low sensitivity to interest rate changes; price volatility has minimal impact if held to maturity | High sensitivity to interest rate movements; bond prices fluctuate significantly with rate changes |
| Risk profile | Exposed more to credit risk and reinvestment risk, as returns depend on issuer quality and yield locking | Exposed primarily to interest rate risk (duration risk), especially in long-duration portfolios |
| Management approach | Passive to semi-active, focused on holding bonds and earning steady income | Active and tactical, requires timing interest rate cycles and adjusting portfolio duration |
Final Thoughts: Role of Accrual and Duration in Fixed Income Strategies in India
Most fixed-income investors combine both strategies to enhance their returns. Accrual strategies typically form the core, especially when rates are stable, offering predictable income through corporate bonds and short-term debt instruments. Duration strategies, on the other hand, are deployed more as a satellite strategy and used more tactically around RBI policy cycles, particularly when rate cuts are expected.
To put simply, there is no single “better” strategy between accrual and duration. When and how you approach each strategy is what matters the most.
