Secured bonds are debt instruments backed by specific assets such as property, equipment, or financial securities. Under Indian capital markets, these are governed by SEBI's Issue and Listing of Non-Convertible Securities (NCS) Regulations, 2021, which mandate the appointment of an independent Debenture Trustee and the maintenance of a defined Asset Cover Ratio.
This article explains what secured bonds are, how they work, the different types available, their key features and risks, and who may consider investing in them.
Key Takeaways
-
Secured bonds are backed by specific collateral pledged by the issuer under a formal Trust Deed.
-
Under the Insolvency and Bankruptcy Code (IBC), 2016, secured bondholders are treated as secured financial creditors, giving them priority claims on pledged assets during default or liquidation, subject to the IBC process.
-
Common collateral includes real estate, equipment, and financial securities.
-
While secured bonds carry lower credit risk for the same issuer, final yields depend heavily on the issuer's credit rating rather than collateral status alone (e.g., a distressed secured bond can out-yield a prime unsecured bond).
-
Investors should assess both the issuer's financial health and the quality of the collateral.
What do Secured Bonds Mean?
A secured bond is a debt security in which repayment is backed by specific assets owned by the issuer. Those assets get pledged as collateral under the bond's legal agreement, usually called the Trust Deed.
The issuer agrees to pay periodic interest and return the principal when the bond matures. If those obligations aren't met, the trustee representing bondholders can enforce rights over the pledged assets, as permitted under the bond's terms.
The key difference from an ordinary bond is that repayment does not rely entirely on the issuer's financial strength. Investors get an extra layer of protection through whatever collateral's actually named in the agreement.
How Secured Bonds Work?
The legal foundation of every secured bond is the Trust Deed. It outlines:
-
The exact assets pledged as collateral.
-
Coupon rates, interest payment frequency, and maturity dates.
-
The mandatory Asset Cover Ratio, which is typically 100% to 125% or more of the principal and interest outstanding, and must be maintained throughout the tenure.
-
The operational responsibilities of the Debenture Trustee.
-
Detailed default clauses and legal enforcement protocols under the IBC, 2016.

Capital-intensive / transport industries |
Ownership structure keeps the equipment tied to repayment obligations until the debt is fully settled. |
Why Do Companies Issue Secured Bonds?
Companies issue secured bonds to raise capital at a lower cost than unsecured borrowing would allow, because the pledged collateral reduces the risk lenders take on.
Risks Associated With Secured Bonds
-
Interest rate risk: Bond prices move inversely to interest rates. If market rates climb, the market value of existing secured bonds can fall before maturity.
-
Credit risk: Even a secured issuer can face severe financial distress. While collateral improves recovery odds, it does not prevent a default.
-
Collateral value risk: Pledged assets can depreciate over time due to falling property values, equipment wear, or market fluctuations in pledged financial securities.
-
Liquidity risk: Low trading volume for certain secured bonds in the secondary market can make selling them before maturity difficult.
-
Legal and enforcement risk: Recovery depends on the Trust Deed, the strength of the security interest, and applicable insolvency laws. In India, enforcing collateral after a default often goes through the IBC process, NCLT, or DRT, which can take a long time. Secured creditors rank ahead of unsecured ones, but recovery is rarely quick or guaranteed in full.

What to Check Before Investing in Secured Bonds?
-
Issuer quality: Revenue growth, debt levels, cash flow, profitability, and credit ratings are vital. Strong collateral cannot fully compensate for a fundamentally weak issuer.
-
Collateral nature: It is essential to understand what asset is pledged, its liquidation feasibility, and whether its value comfortably covers the outstanding debt.
-
Credit rating: Ratings remain useful for secured bonds as agencies evaluate issuer strength, collateral quality, bond structure, and recovery prospects combined.
-
Bond terms: Coupon frequency, maturity periods, redemption provisions, and default clauses dictate how the security functions in practice.
Who Can Consider Investing in Secured Bonds?
Secured bonds tend to suit investors seeking relatively predictable income while prioritising capital preservation over aggressive growth.
That can mean conservative investors generally, retirees looking for fixed income, people balancing an equity-heavy portfolio, or anyone specifically seeking lower credit risk in corporate bonds. That said, these should still be part of a genuinely diversified approach, not the entire fixed-income allocation on their own.
Conclusion
Secured bonds combine regular income with an extra layer of protection through pledged collateral. Giving bondholders priority claims on specific assets when repayment problems arise generally means lower credit risk than unsecured bonds carry, though they are still exposed to interest rate moves, collateral value shifts, and legal enforcement risk.
Before investing, weigh both the issuer’s financial strength and the quality of the pledged collateral.
