Government Owned Isn't Government Guaranteed. Here's What PSU Bonds Actually Promise You
PSU Bonds Explained: What Public Sector Undertaking Bonds Are, and What They're Not
Suresh retired from a nationalised bank after thirty two years behind the same counter. He knew fixed deposits inside out. He did not know bonds, and he was cautious enough to admit it to himself before admitting it to his son, who had started nudging him toward "something better than an FD."
Scrolling through a bond platform for the first time, one line stopped him.
Issued by a Public Sector Undertaking.
That was enough. He didn't check the rating. He didn't check whether the bond was secured. In his head, the arithmetic was simple: PSU means the government owns it, and the government does not default. He invested a meaningful chunk of his retirement corpus that same evening, satisfied he'd found the FD replacement he was looking for.
He wasn't wrong that PSU bonds deserve serious consideration. He was wrong about why.
Ownership and guarantee are not the same word, even though they sit right next to each other in most people's heads. Understanding the difference is the entire point of this guide, and it's more useful than any yield number you're about to read.
What Are PSU Bonds?
A PSU bond is a debt instrument issued by a Public Sector Undertaking, a company in which the central or state government holds majority ownership. The common convention, used to classify Central Public Sector Enterprises, sets that threshold at 51% or more of paid up equity, though exact classification can vary a little, including cases where the government's stake is held indirectly through other government owned entities. Structurally, the bond itself works exactly like any other bond: the issuer borrows from investors, pays periodic interest, and repays the face value at maturity. What changes is who is doing the borrowing, a government owned enterprise rather than a privately held company.
That single fact, government ownership, shapes investor perception more than almost anything else in the bond market. It's also the fact most frequently misread.
PSU Bonds at a Glance
| Feature | What It Means |
|---|---|
| What is a PSU bond? | A bond issued by a company where government holds majority ownership |
| Issued by | Central or state government owned enterprises (NTPC, PFC, REC, NHAI, HUDCO, IRFC and similar) |
| Ownership vs guarantee | Government owned does not automatically mean government guaranteed |
| Typical credit rating range | Often high, frequently AAA for the largest issuers, but not universal across every PSU |
| Secured or unsecured | Varies by specific bond, always confirm in the offer document |
| Typically suits | Investors seeking high credit quality income with a modest premium over G-Secs |
| Tax treatment | Mostly taxable; a legacy category of tax free PSU bonds also exists |
What Actually Makes a Company a PSU
Not every large, familiar name with government ties qualifies. Under the common classification convention, a PSU is a company where the government's equity stake crosses 51%, giving it controlling ownership and a seat at every major decision.
India further ranks its central PSUs by scale and operational independence: Maharatna (the largest and most autonomous), Navratna, and Miniratna, in descending order of financial and operational freedom granted by the government. This ranking affects how a company runs its business, not how its bonds are legally backed, but it's a useful signal of scale and institutional maturity when you're evaluating an issuer.
Well known central PSUs active in India's bond market include NTPC, Power Grid Corporation, NHPC, PFC, REC, NHAI, HUDCO, IRFC, and NABARD, among others. Some states run their own PSUs too, issuing bonds through state owned power, infrastructure, and finance corporations.
Ownership Is Not a Guarantee. This Is the Part Most Investors Skip.
Here's the misconception, stated plainly: many investors assume that because the government owns a majority stake in a company, the government has also promised to pay back that company's debts if it can't. That assumption is usually wrong.
In the overwhelming majority of cases, a PSU bond is backed by the financial strength of the issuing company itself, its cash flows, its balance sheet, its ability to service debt, exactly the way a private company's bond would be evaluated. Credit rating agencies do factor in an issuer's PSU status when assigning a rating, because government ownership can imply a degree of strategic importance and a reasonable expectation of support in a crisis. But an expectation is not a contract. Unless a specific bond's offer document explicitly states that the government has guaranteed repayment, and a small number of specific issues do carry that explicit clause, the bond stands on the issuer's own creditworthiness.
Myth: PSU bonds are backed by the government, so they can't default.
Fact: PSU bonds are issued by government owned companies. Unless a specific bond's offer document explicitly states an official government guarantee, repayment depends on that company's own financial health, the same as any other corporate bond.
The clearest illustration of this gap isn't even a PSU itself, but it's close enough to matter. IL&FS, majority owned by public sector giants LIC and SBI rather than by government directly, defaulted in 2018 despite a widespread market assumption that its ownership meant an implicit safety net. That safety net wasn't there. The shock rippled through India's debt mutual fund industry for months.
The lesson isn't that PSU adjacent ownership is meaningless. It's that it's not a substitute for actually checking the credit rating, the secured or unsecured status, and the specific issuer's own numbers, every single time, regardless of how reassuring the ownership structure sounds.
Taxable PSU Bonds vs Tax Free PSU Bonds
PSU bonds split into two broad tax categories, and the difference is significant enough to change which one actually suits you.
| Category | Interest Taxation | Typical Vintage | Notes |
|---|---|---|---|
| Taxable PSU bonds | Interest taxed at your income slab rate | Issued on an ongoing basis | The default category for most current PSU bond issuances |
| Tax free PSU bonds | Interest exempt from income tax under Section 10(15) | Issued in notified tranches, mainly between 2011 and early 2016 | No new tranches have been issued since 2016; existing ones trade in the secondary market |
For an investor in a high tax bracket, an older tax-free PSU bond trading in the secondary market can offer a post tax return that comfortably beats a comparable taxable instrument, even at a lower headline coupon. The catch is availability. These are a fixed, shrinking pool of legacy bonds, not something new investors can subscribe to directly from the issuer anymore.
How PSU Bonds Compare to G-Secs and Private Corporate Bonds
| Government Securities (G-Secs) | PSU Bonds | Private Corporate Bonds | |
|---|---|---|---|
| Issued by | Central government directly | Government owned companies | Privately held companies |
| Nature of backing | Sovereign, backed by the Government of India itself | Company's own financials, ownership does not equal guarantee | Company's own financials |
| Typical credit rating | Generally considered to carry negligible credit or default risk in domestic currency terms | Often high, commonly AAA for the largest names, but varies | Ranges widely, from AAA to sub investment grade |
| Typical yield positioning | Usually the reference point, the lowest yield on the curve | Usually a modest premium over comparable G-Secs | Usually the widest range, depending on credit quality |
| What you're really evaluating | Almost nothing beyond tenor | The issuer's specific financials and the bond's specific terms | The issuer's specific financials and the bond's specific terms |
The practical takeaway sits in that last row. A PSU bond asks for nearly the same diligence as a private corporate bond. Government ownership narrows the field of genuinely troubling names, but it doesn't remove the homework.
A Simple Example of Why the Spread Exists
Here's a hypothetical illustration to make the pricing logic concrete. This is a simplified example for explanation only. It does not represent a real bond, a real issuer, or any bond currently listed on Finzace.
Imagine a Government Security maturing in seven years is trading at a yield of 7.1%. A hypothetical AAA rated PSU bond of similar tenor is trading at 7.6%. That 0.5 percentage point gap is called the credit spread, and it exists for a simple reason: the PSU bond, however strong, is still a corporate obligation, not a sovereign one. The market is pricing in a small premium for that difference, however slight it may be for a highly rated issuer.
If a PSU bond of similar tenor were instead priced with a spread of 2 or 3 percentage points over the comparable G-Sec, that would be worth pausing on. A wider spread usually means the market is pricing in meaningfully more risk than the issuer's PSU status alone might suggest, and it's worth checking the rating and the specific terms before assuming the extra yield is simply a bonus.

What to Actually Check Before Investing in a PSU Bond
Treat this the way you'd treat any corporate bond, because that's what it legally is.
The credit rating, not the PSU label. Look up the specific bond's rating from CRISIL, ICRA, CARE, or India Ratings. Don't assume AAA. Some PSUs, particularly smaller state level entities, carry materially lower ratings.
Secured or unsecured status. Some PSU bonds are secured against specific assets or receivables. Others are unsecured, relying entirely on the issuer's general creditworthiness. This is disclosed in the offer document for every issue, and it changes your position if the issuer runs into trouble.
The spread over a comparable G-Sec. A small, reasonable spread reflects the corporate versus sovereign distinction. An unusually wide spread is a signal to look closer, not a reason to celebrate.
Tenor against your own timeline. PSU bonds span the same short, medium, and long term range as any other bond category. A longer tenor means more price sensitivity to interest rate movements if you need to exit before maturity.
Tax status. Confirm whether you're looking at a taxable issue or one of the older tax free tranches, since the post tax math changes considerably between the two.
Who PSU Bonds Actually Suit
PSU bonds tend to sit toward the higher credit quality end of the corporate bond spectrum, which shapes who gets the most value from them.
They suit investors who want meaningfully more yield than a G-Sec without stepping far down the credit curve to get it, retirees and conservative investors who prioritise predictable income and are comfortable with a company level, rather than sovereign level, risk profile, and higher tax bracket investors specifically hunting for legacy tax free tranches in the secondary market.
They're a less natural fit for investors chasing the highest yields the bond market has to offer. That kind of return typically sits with lower rated, higher risk corporate issuers, a different conversation entirely, and one where the PSU label offers no particular advantage.
Common Questions About PSU Bonds
Q. What is a PSU bond in simple terms? A. It's a bond issued by a company where the central or state government owns a majority stake, usually 51% or more. It functions like any other bond: regular interest payments, with the principal returned at maturity.
Q. Are PSU bonds risk free? A. No. They generally carry lower risk than the broader corporate bond market because many large PSU issuers hold strong credit ratings, but risk free is reserved for sovereign instruments like Government Securities. PSU bonds still carry credit risk tied to the specific issuer and interest rate risk tied to the bond's tenor.
Q. Are PSU bonds guaranteed by the government? A. Not by default. Government ownership is not the same as a government guarantee. A small number of specific bond issues do carry an explicit repayment guarantee stated in that bond's offer document, but this is the exception, not a standard feature of PSU bonds as a category. Always check the specific offer document rather than assuming.
Q. What is the difference between a PSU bond and a Government Security (G-Sec)? A. A G-Sec is issued directly by the Government of India and carries sovereign backing. A PSU bond is issued by a company the government owns a majority stake in, and it's backed by that company's own financial strength, not by a direct sovereign promise, unless explicitly stated otherwise in that specific bond's terms.
Q. Are PSU bonds tax free? A. Most current PSU bonds are taxable, with interest taxed at your income slab rate. A specific legacy category, tax free PSU bonds, was issued in notified tranches mainly between 2011 and early 2016 under Section 10(15), and interest on those remains exempt. No new tax free tranches have been issued since 2016; the existing ones trade in the secondary market.
Q. Are PSU bonds secured or unsecured? A. It varies bond by bond. Some carry security against specific assets or receivables, others are unsecured. This is disclosed in the offer document for each individual issue and should be confirmed before investing rather than assumed from the issuer's PSU status.
Q. Can a PSU bond default? A. Yes, in principle, if the issuing company's finances deteriorate enough and no explicit government guarantee applies to that specific bond. In practice, large, well established PSU issuers with strong ratings have a low historical default rate, but low is not zero, and credit quality should still be checked on each issue rather than assumed.
Q. Who should consider investing in PSU bonds? A. Investors who want a step up in yield over G-Secs while staying close to the higher end of the credit quality spectrum, retirees and conservative investors prioritising predictable income, and higher tax bracket investors interested in legacy tax free tranches where still available in the secondary market.
The Real Takeaway
Suresh's bond turned out fine. The issuer was a large, genuinely strong PSU with a solid rating, and his instinct, if you squint, was pointed in a reasonable direction. But it worked out despite his reasoning, not because of it. He got lucky on a decision he made for the wrong reason, and luck is not a strategy anyone should be repeating with a retirement corpus.
PSU status is a useful signal. It's not a substitute for the rating, the security status, and the specific terms sitting in front of you. Read those, every time, and the ownership structure becomes what it should have been from the start, one more data point, not the entire decision.
That's also the more useful question to bring to wherever you're actually browsing bonds, not "is this a PSU," but "can I see the rating, the tenor, and the secured or unsecured status without digging for it." On Finzace, PSU and other bonds are listed via Aspero, a SEBI-registered Online Bond Platform Provider, with exactly that laid out on one screen, so it's the numbers you end up checking, not the label.
