Thinking of buying bonds online? 6 risks and rules investors should know

Online Bond Platform Providers (OBPPs) are digital marketplaces where retail investors can buy listed bonds. After SEBI cut the minimum bond face value in 2024, these platforms became accessible to ordinary investors.
Before you put your money, it’s important to grasp the key risks involved and how to protect your money from expensive blunders.

If a bond or SDI on these platforms is offering 13–15% returns, the underlying credit risk is high. Bonds that are similarly rated can carry very different risk levels depending on the issuer's cash flows and sector. You shouldn’t invest based on the return number alone. When a product labelled as a bond or SDI offers equity-like yields, that is a red flag in itself, not an opportunity.

Platforms market bonds as "curated," "secured," and "fully compliant." But real dangers such as borrower credit quality, sector cyclicality, and cash-flow volatility are buried in fine print that most retail investors never read. Platforms are incentivised by volume and fees, not by how your investment performs.

SDIs often come with over-collateralisation and cash collateral. These reduce risk but do not eliminate it. They are built to absorb normal default levels and not sectoral stress. When asset quality deteriorates sharply, as it did in microfinance, these buffers get overwhelmed. During a crisis, guarantors default, collateral values fall, and legal recovery drags on for months. A partial payout is not the same as capital safety.

⦁ Senior secured bonds: First to be repaid, backed by collateral, best downside protection
⦁ Senior unsecured bonds: No collateral, paid after secured creditors, recovery is uncertain
⦁ Subordinated / Tier-2 bonds: Near the bottom, absorb losses before senior holders
⦁ AT1 / Perpetual bonds: Last in line, can be written down entirely in a crisis
The lower your bond sits in this hierarchy, the lower your chances of getting your principal back if the issuer defaults.

Most investors treat bond platform products as a safe alternative to fixed deposits. However, they are not as these platforms improve access and transparency but not liquidity. Secondary market demand is thin, and a minor rating downgrade can freeze buyers overnight. Internal resale windows are not guaranteed. If you need money in a hurry, you may not be able to exit at a fair price or at all. Keep emergency and short-term funds in liquid, low-risk instruments only.

While SEBI's framework mandates disclosures, order receipts, and transparent records, it does not guarantee credit quality or prevent product mis-selling.
Platforms are intermediaries and facilitate the transaction, but the credit risk is entirely yours. Past enforcement shows some platforms pushed aggressive products until regulators stepped in. Remember, your due diligence cannot be outsourced to the platform or its regulator.
