Summary: PSU bonds are debt instruments issued by government-owned companies to raise long-term capital for infrastructure and development projects. This guide covers how PSU bonds work, what determines their interest rates, their risks and benefits, and how to evaluate them in India’s evolving bond market.
Quick Overview
- Government-owned public sector undertakings issue PSU bonds
- They often offer higher yields when compared to government securities
- PSU bonds are not the same as sovereign government bonds
- Interest rates vary based on issuer quality and market conditions
- Government ownership may improve your investment confidence, but it does not eliminate risk
- PSU bonds remain an important segment of India’s fixed-income market
Public Sector Undertaking (PSU) bonds are debt instruments issued by government-owned companies to raise capital for business operations, infrastructure projects, and expansion plans. As India’s debt market evolves, PSU bonds are gaining traction as the most widely used fixed-income instrument, offering a different balance of risk, yield, and issuer exposure than government securities and corporate bonds.
This article explores how PSU bonds work, their advantages and risks, liquidity considerations, and where they may fit within a fixed-income portfolio.
What are PSU Bonds?
PSU bonds are debt instruments issued by Public Sector Undertakings (PSUs), where you lend money to government-owned companies rather than directly to the central government.
Major PSU issuers in India include:
- National Highways Authority of India (NHAI)
- Rural Electrification Corporation (REC)
- Power Finance Corporation (PFC)
- Indian Railway Finance Corporation (IRFC)
These institutions raise capital to fund infrastructure and long-term development projects.
Unlike government bonds, PSU bonds depend on the issuing company’s financial strength for repayment, even though ownership remains with the government. Depending on their credit ratings, they offer coupon rates of 5%- 12.75%.
Why do Public Sector Undertakings Issue Bonds?
PSUs often manage large, long-term projects that require substantial funding, sometimes running into thousands of crores over several years, making bank loans alone impractical. To meet their capital needs, they raise money through bonds.
These funds are used for infrastructure and development projects, including highways, railway networks, power transmission systems, and urban development initiatives. According to the RBI Annual Report 2024-25, primary corporate bond issuances increased by 16.1% to ₹9.9 trillion in FY25, highlighting the growing role of bonds in raising long-term capital.
Bond issuance also allows PSUs to access long-term capital that matches the duration of these projects and helps diversify their funding sources beyond traditional bank financing.
For you, PSU bonds offer an opportunity to participate in financing large-scale development projects while earning fixed-income returns.
How do PSU Bonds Work?
PSU bonds follow a straightforward borrowing and repayment structure.
When you invest in a PSU bond, you lend money to the issuing public sector undertaking for a fixed period. In return, the issuer pays you interest at regular intervals throughout the bond’s tenure. This interest payment is known as the coupon. Once the bond reaches maturity, the issuer repays your principal amount.
Before a bond is issued, credit rating agencies evaluate the issuer’s financial strength, repayment capacity, and overall risk profile. These ratings help you assess the credit quality of the bond before investing.
When evaluating returns, it is important to understand the difference between the coupon rate and yield.
- Coupon rate: The fixed interest rate paid on the bond’s face value. It remains unchanged throughout the bond’s tenure.
- Yield: The actual return you earn based on the price at which you buy the bond. If you purchase a bond above or below its face value, your yield will differ from the coupon rate.
Many PSU bonds are also traded in the secondary market. As a result, their prices can move up or down based on interest-rate changes, market demand, liquidity, and your perception of the issuer.
What Determines PSU Bond Interest Rates?
PSU bonds’ interest rates are not fixed across all issuers. The return you earn depends on a combination of issuer-specific and market-driven factors.
- Credit rating: PSU issuers with stronger credit ratings can generally borrow at lower interest rates because they may be viewed as more reliable.
- Bond tenure: Longer-term bonds usually offer higher yields because you commit your capital for longer and face greater uncertainty.
- Market interest rates: Changes in overall interest rates affect bond pricing, and newly issued bonds typically offer higher coupons when market rates rise.
- Financial strength of the issuer: A PSU’s profitability, cash flows, debt levels, and repayment capacity play an important role in determining the interest rate offered on its bonds.
- Demand and liquidity: Bonds that attract strong investment demand often offer lower yields, while less liquid bonds may provide higher returns to compensate you.
Why do PSU Bonds Offer Higher Yields than Government Securities?
PSU bonds typically trade at a yield premium to government securities. Let us understand how.
When you invest in a government security, you lend money directly to the Government of India. Because these securities carry sovereign backing, they are generally considered among the safest fixed-income instruments in the market. As a result, they typically offer lower yields.
PSU bonds are different. Although government-owned entities issue them, the repayment responsibility lies with the issuing company rather than the central government. This means you are exposed to the financial strength and credit profile of the individual PSU.
Some PSU bonds are less liquid than government securities. If a bond does not trade actively in the secondary market, you usually expect a higher return for holding it. In return, the market rewards you with a higher yield because you take on slightly more credit and liquidity risk than you would with a sovereign bond.
Simply put, PSU bonds offer higher returns because the risks are not identical. The additional yield reflects the extra risk you accept.
Benefits of Investing in PSU Bonds
PSU bonds can offer several advantages if you are looking to strengthen the fixed-income portion of your portfolio.
- Higher yield potential: PSU bonds often offer higher returns than many government securities. This yield premium can help improve the income generated by your investments.
- Predictable income: Most PSU bonds pay interest at fixed intervals. This provides a steady, predictable income stream throughout the bond’s tenure.
- Strong credit profile: Many PSU issuers are large government-owned entities operating in critical sectors of the economy. As a result, their bonds are often viewed as relatively high-quality fixed-income investments.
- Portfolio diversification: PSU bonds allow you to diversify beyond fixed deposits and government bonds. This can help create a more balanced fixed-income portfolio.
- Flexible investment options: PSU bonds are available across different maturities and issuers. This gives you the flexibility to choose investments that align with your financial goals and investment horizon.

Risks Associated with PSU Bonds
While PSU bonds can be attractive due to higher yield potential, you should understand the risks involved before investing.
- Credit risk: Repayment depends on the issuing PSU’s financial strength. Government ownership does not completely eliminate credit risk.
- Interest rate risk: If interest rates rise, the market value of existing bonds may fall. This matters if you plan to sell before maturity.
- Liquidity risk: Some PSU bonds may not trade actively in the secondary market. Lower liquidity can make buying or selling more difficult.
- Market price volatility: Bond prices can fluctuate because of changes in interest rates, demand, and market conditions.
- Reinvestment risk: If interest rates decline, you may have to reinvest coupon payments at lower rates, which can reduce future income.
PSU Bonds vs. Government Bonds
Although both instruments are linked to the government, they differ in who is responsible for repayment and the level of risk involved. Here’s how:
| Feature | Government Bonds | PSU Bonds |
| Issuer | Government of India (through RBI) | Government-owned companies |
| Repayment source | Sovereign obligation | Issuing PSU |
| Credit risk | Lowest in the domestic debt market | Depends on the issuer’s financial strength |
| Yield | Usually lower | Usually higher |
| Liquidity | Generally, a deeper secondary market | Varies by issuer and issue size |
| Suitable for | Capital preservation focus | Income enhancement with moderate additional risk |
How You Can Buy, Sell, and Transfer PSU Bonds?
You can invest in PSU bonds either during a primary issuance or through the secondary market. In a primary issuance, you purchase the bond directly from the issuer when it is first offered in the market. Alternatively, you can buy existing PSU bonds through exchanges and bond investment platforms at prevailing market prices.
PSU bonds are typically held in demat form, making ownership electronic and easy to manage. Listed PSU bonds are generally held in demat form. Ownership changes when bonds are bought or sold through exchanges or authorized bond platforms, while off-market transfers can be executed through the depository system, subject to applicable rules.
Please keep in mind that liquidity can vary across issuers. Bonds issued by larger and well-known PSUs generally see more trading activity, while smaller issues may be less liquid. This can affect how easily you can buy or sell a bond when needed.
Who Can Consider PSU Bonds?
PSU bonds may suit you if you seek regular income, relatively strong credit quality, and higher yields than government securities. They also help diversify fixed-income portfolios.
They are suitable for medium- to long-term, if you are willing to take a slightly higher risk for better returns and exposure to infrastructure, power, transport, and finance sectors without investing in equities.
Before investing, consider credit rating, liquidity, tenure, interest rate outlook, and asset allocation. They work best as part of a diversified portfolio.
Conclusion
India’s infrastructure and development ambitions require substantial long-term capital, and public sector enterprises play a central role in this process. As these organizations increasingly raise funds through bond markets, PSU bonds have become an important segment of the country’s fixed-income ecosystem.
Their relevance is likely to increase further as India’s financing needs expand and capital markets play a larger role in funding economic growth. Understanding how PSU bonds work, the risks they carry, and how they differ from government and corporate bonds can help you evaluate where they fit within the broader fixed-income universe.
