NSE Nifty Fixed Income Indices: Meaning, Types, and More

When the word "index" pops up in our heads, we usually think of the Nifty 50 or Sensex. However, stock markets are not the only markets with indices. Debt markets also have indices that help investors see how different kinds of fixed‑income securities are doing.

NSE Nifty Fixed Income Indices track the performance of debt instruments, such as government bonds, state development loans (SDLs), corporate bonds, and money‑market instruments. Nifty Fixed Income Indices provide a benchmark for the fixed‑income market and are also used as benchmarks for some ETFs, index funds, and other investment products.

This article answers various questions, such as what exactly Nifty Fixed Income Indices are, how they are created, and more.

What are Fixed-Income Indices?

Fixed‑income indices are collections of debt securities that track a segment of the market based on a set of rules. Instead of focusing on a single bond, an investor can look at a fixed‑income index to see how a particular segment of the bond market is performing. For example, an index could track government bonds with a particular maturity range. Another fixed‑income index could follow bonds that are issued by companies or by government‑owned entities. NSE Indices offers fixed‑income index categories, such as G‑Sec indices, SDL indices, corporate bond indices, money‑market indices, target‑maturity indices and aggregate debt indices.

How are Nifty fixed-Income indices created?

The construction depends on the type of index. Take G-Sec indices as an example. These indices select Government of India securities by looking at factors such as maturity, outstanding amount, and liquidity. The Nifty G‑Sec index family contains categories such as ultra‑short, low, short, medium, medium‑to‑long and long‑duration G‑Sec indices. These Nifty G‑Sec indices are reviewed periodically based on their respective methodologies. Some indices follow a different approach. For example, the Nifty 10‑year Benchmark G‑Sec Index tracks the liquid 10‑year benchmark government security. This rules‑based approach makes the indices useful as benchmarks for investors and fund managers.

Major Types of NSE Fixed-Income Indices

G-Sec Indices

Government securities (G-Secs) are bonds issued by the Government of India. Nifty G-Sec indices track different maturity segments, along with benchmark and composite indices. For example, the Nifty Composite G-Sec Index tracks a basket of liquid government bonds. A key point is interest-rate sensitivity: longer-duration bonds are generally more sensitive to interest-rate changes than shorter-duration bonds.

SDL Indices

State Development Loans (SDLs) are securities issued by state governments to raise funds. NSE Indices offers SDL indices across different maturity segments, such as 3-year, 5-year, and 10-year maturities, helping investors track the performance of state government debt.

Corporate Bond and Aggregate Debt Indices

NSE also has indices covering corporate bonds and broader debt markets. The Nifty Fixed Income Aggregate Index series includes Nifty Corporate Bond, Nifty Banking & PSU Debt, Nifty Credit Risk Bond, Nifty Money Market, and Nifty Composite Debt. These indices provide a broader view of different debt-market segments.

Target-Maturity and BHARAT Bond Indices

Target-maturity indices are built around a specific maturity date. The Nifty BHARAT Bond Index series tracks eligible bonds maturing around a target date, making the indices useful for investors with a defined investment horizon. However, an index itself cannot be directly purchased. ETFs or index funds can be designed to track these indices.

Fixed-Income Indices vs Equity Indices

Equity indices such as the Nifty 50 track shares of companies. Fixed-income indices, on the other hand, track debt securities. The two also behave differently. Equity returns can be driven by factors such as company earnings, valuations, and economic growth. Fixed-income returns are influenced by factors such as interest rates, bond yields, credit quality, maturity, and liquidity. This does not mean fixed-income investments cannot lose value. Bond prices can move up or down, especially when interest rates change.

Therefore, fixed-income investments should not simply be viewed as “risk-free”. The type of bond, duration, credit quality, and investment product all matter.

FAQs

What is a Nifty fixed-income index?

A Nifty fixed-income index is a rules-based basket that tracks the performance of selected debt securities. Depending on the index, it may track government bonds, SDLs, corporate bonds, money-market instruments, or other fixed-income securities.

Are Nifty fixed-income indices risk-free?

Not necessarily. Government securities have very low credit risk because they are issued by the government, but their market prices can still fluctuate when interest rates change. Other fixed-income indices may also carry credit and liquidity risks.

What is duration in a bond index?

Duration is a measure of how sensitive a bond or bond portfolio is to changes in interest rates. In general, a higher-duration portfolio will see a larger price movement for a given change in interest rates.

Can I invest directly in a Nifty fixed-income index?

No. An index itself is a benchmark, not an investment product. However, ETFs, index funds, and other investment products may track a particular fixed-income index.

Why are G-Sec indices important?

G-Sec indices provide benchmarks for different segments of the Government of India bond market. They can help investors and fund managers track market performance and understand how different maturity segments are behaving.
