Secured vs Unsecured NCDs: Does the Collateral Actually Protect You?
When you see “Secured NCD” on a bond offer document, it is easy to read “safe.” The two words are not synonyms. A security charge gives you a legal claim on specific assets — but the practical value of that claim depends on what those assets are worth, how quickly they can be enforced, and who else has a prior claim. This article explains what the label actually means, and what it does not.
What “secured” means in Indian law
A secured NCD (Non-Convertible Debenture) is backed by a charge on the issuer’s assets. The charge is registered with the Registrar of Companies (RoC) and administered by a Debenture Trustee — a SEBI-registered entity that acts as the representative of debenture holders as a class.
Two main types of charge:
- Fixed charge: A specific, identified asset (a plot of land, a building, specific receivables). If the issuer defaults, those exact assets are earmarked for debenture holders.
- Floating charge: A charge over a pool of assets that changes over time — typically the issuer’s loan book (receivables). The charge “crystallises” (converts to a fixed claim) only when the issuer defaults or enters liquidation. Until then, the issuer can add and remove assets from the pool in the ordinary course of business.
Most NBFC NCDs use a floating charge over their loan receivables. This is standard practice, not a red flag — but it means you are not holding a claim on a specific, ring-fenced asset. You are holding a claim on a pool that could shrink if the loan book deteriorates.
The debenture trustee’s role — and its limits
The debenture trustee is supposed to monitor the issuer, ensure the security cover is maintained at the promised ratio (typically 1.0x or 1.1x of outstanding debentures), and act on behalf of debenture holders if there is a default.
In practice, the trustee’s effectiveness depends on:
- The quality and independence of the trustee firm
- The frequency and rigour of asset verification
- Whether the trust deed gives the trustee clear enforcement powers
- How quickly the trustee acts when covenant breaches appear
SEBI has strengthened debenture trustee regulations over the years, including requiring trustees to file compliance reports and take enforcement action within defined timelines. This has improved governance. But enforcement still takes time, and the trustee cannot create value in assets that have already deteriorated.
How enforcement works in practice
When an issuer defaults on a secured NCD, the enforcement process typically involves:
- The debenture trustee calling an event of default and convening a debenture holders’ meeting
- Passing a resolution to enforce the security
- Appointing a receiver or liquidator to take control of the charged assets
- Selling the assets and distributing proceeds to debenture holders
Each step takes time. Indian insolvency proceedings have improved significantly since the Insolvency and Bankruptcy Code (IBC) was introduced in 2016, with clearer timelines and stronger creditor rights than existed before. Complex cases still take time to resolve, and the pace depends heavily on how liquid and well-documented the charged assets are.
Recovery rates vary depending on asset quality. Secured creditors with well-collateralised, liquid assets can recover a high proportion of their principal. The key variable is whether the underlying assets retain their value through the resolution period.
Historical lessons from large-scale credit events
Two episodes from Indian fixed income history illustrate what can happen when multiple factors combine: complex corporate structures, rapid balance sheet growth, and liquidity stress.
IL&FS (Infrastructure Leasing & Financial Services), 2018: IL&FS was an AAA-rated infrastructure NBFC that began defaulting on its obligations in September 2018. The group had a complex multi-entity structure with over 300 subsidiaries. When defaults cascaded, debenture holders faced a situation where the assets were long-term infrastructure projects that were difficult to value and even more difficult to sell quickly. The resolution process took several years. This episode highlighted that high ratings and secured collateral do not guarantee smooth recovery if the underlying assets are illiquid and the corporate structure is opaque.
DHFL (Dewan Housing Finance Corporation), 2019: DHFL, a large housing finance company, defaulted in 2019 following a governance crisis. The case went through IBC resolution, with a plan approved in 2021. The key lesson is that “secured by mortgage receivables” does not mean automatic, full recovery — the quality of the underlying mortgages, the concentration of related-party exposures, and the availability of buyers for the asset book all shaped the outcome.
These are exceptional cases — the vast majority of Indian NCD issuers service their debt without incident. The point is not that NCDs are dangerous. The point is that the “secured” label is not a substitute for understanding the underlying credit quality.
Secured vs unsecured: the practical comparison
| Factor | Secured NCD | Unsecured NCD |
|---|---|---|
| Claim on assets | Yes — specific or floating charge | No — general creditor |
| Priority in liquidation | Ahead of unsecured creditors | Behind secured creditors |
| Typical yield | Lower (reflects security) | Higher (reflects weaker claim) |
| Recovery if issuer defaults | Depends on asset quality and enforcement | Depends on what is left after secured creditors |
| Key risk | Asset quality deterioration; slow enforcement | Nothing between you and the default |
When a strong unsecured issuer beats a weak secured one
This is the core insight: the security label matters less than the issuer’s ability to repay.
A secured NCD from a highly leveraged NBFC with deteriorating asset quality, concentrated exposures, and thin liquidity buffers carries more real risk than an unsecured bond from a AAA-rated PSU with strong government backing and transparent financials.
Security improves your position if there is a default. It does not reduce the probability of a default. For that, you need to evaluate:
- The issuer’s credit rating and trend (multiple reaffirmations vs recent downgrades)
- Leverage ratio — for NBFCs, debt / net worth; look for significant deterioration over time
- Asset quality — Gross NPA ratio, provisioning levels, proportion of restructured loans
- Liquidity — can the issuer roll over short-term borrowings comfortably?
- Promoter and governance quality — this is qualitative but material
How to check the security details of a specific NCD
The information is in the offer document. Here is where to look:
- Section on “Security” or “Security Creation”: Describes what assets are being charged, the security cover ratio, and the name of the debenture trustee.
- Security cover ratio: Usually stated as a minimum, e.g., “security cover of at least 1.0x at all times.” A 1.0x cover means the assets backing the bond are worth exactly the outstanding principal — any deterioration erodes the cushion entirely.
- Debenture trustee: Established trustee firms include IDBI Trusteeship, Catalyst Trusteeship, SBICAP Trustee, and others. Verify the trustee is registered with SEBI.
- Charge type: Fixed or floating. If floating, understand what the underlying pool consists of.
Offer documents are available on the BSE/NSE filings, SEBI’s SEBI EDGAR portal, and the issuer’s website.
Key takeaways
- “Secured” means a legal claim on assets — not a guarantee of full or timely recovery.
- Floating charges on loan receivables are standard for NBFCs. The quality of those receivables is what matters.
- IBC has made enforcement cleaner than it was pre-2016, but asset quality at the time of default still determines the practical outcome.
- A strong unsecured issuer is safer than a weak secured issuer. Credit quality is more important than the security label.
- Always read the security section of the offer document. Check the debenture trustee’s name, the charge type, and the security cover ratio.
