Loan Against Securities: Liquidity Tool or Margin-Call Trap?

This guide explains the loan-to-value mechanics, what actually triggers a margin call, and how to avoid a forced sale at the worst possible time.

1. What a loan against securities actually is

A loan against securities is a credit line or term loan from a bank or NBFC, secured by a lien over the borrower’s own shares, mutual fund units, bonds or insurance policies, without transferring ownership. The lender does not take the securities into its own demat account. Since the September 2020 depository reform that followed Karvy Stock Broking’s 2019 misuse of client securities held under the old power-of-attorney system, the pledge is created and released electronically through the depository (NSDL or CDSL) with the borrower’s own OTP authorisation, while the securities stay in the borrower’s demat account under a marked lien.

2. The loan-to-value ceiling and why it moves

RBI guidelines cap the loan-to-value ratio at 50% of the market value of pledged listed shares; the exact ceiling and haircut can differ for mutual fund units, bonds and other instruments, and individual lenders may apply a stricter internal limit than the regulatory ceiling. Because the ceiling is checked against the current market value, not the value on the day the loan was sanctioned, a fall in the price of the pledged securities raises the effective LTV on the same outstanding loan amount — with no new borrowing at all.

4. Practical action checklist

• Get the exact LTV, haircut and margin-call cure period for your specific securities in writing before pledging.
• Confirm the pledge runs through the depository’s margin-pledge system (NSDL/CDSL, OTP-authorised), not an off-market transfer or a power of attorney over your demat account.
• Track the current market value of the pledged securities against the outstanding loan regularly, not only when a margin-call notice arrives.
• Know the exact cure period the agreement allows to add collateral or repay before the lender can invoke the pledge.
• Avoid pledging a concentrated or illiquid, high-volatility holding as the sole collateral for a loan you cannot afford to lose.

5. Evidence file checklist

6. Common mistakes

• Treating the sanctioned loan amount as fixed, without tracking that the effective LTV moves with the market price of the pledged securities.
• Using LAS proceeds to buy more of the same or a related security, compounding the fall that could trigger the margin call in the first place.
• Pledging the only liquid holdings meant as an emergency fund, leaving nothing spare to add as collateral if a margin call arrives.
• Treating a relationship manager’s verbal assurance about the cure period as equivalent to the written loan agreement’s actual clause.
• Not checking whether the lender uses the post-2020 depository margin-pledge system or an older, less transparent pledge or transfer method.

7. Red flags

• Lender asks for a power of attorney or an off-market transfer of securities into its own name instead of a depository margin pledge.
• No written LTV, margin-call trigger level or cure-period clause in the loan agreement.
• Pressure to pledge additional unrelated securities without a revised written sanction.
• A margin-call notice with a cure window shorter than the original agreement specifies.
• The loan marketed as risk-free or as having no possibility of a margin call.
