Comparing LAMF with Overdraft Against Fixed Deposits
For investors who want revolving access to credit without selling their assets, two secured overdraft products stand out in the Indian financial market: the Overdraft Against Fixed Deposit and the Loan Against Mutual Fund. Both provide a credit line secured by a financial asset, both allow you to draw and repay flexibly, and both preserve the underlying investment during the borrowing period. But the similarities end there. The two products differ significantly in their collateral type, interest rate structure, LTV, risk profile, and the kinds of borrowers and situations they are best suited for.
Understanding these differences in depth allows investors with both fixed deposits and mutual fund portfolios to make deliberate choices about which product to use for which need.
The Overdraft Against Fixed Deposit — Structure and Mechanics
An Overdraft Against Fixed Deposit is provided by the same bank that holds your FD. The bank creates an overdraft account linked to your current or savings account, against which you can draw up to a specified limit — typically 80 to 90 percent of the FD value. The FD continues to earn interest throughout the overdraft period. The overdraft interest rate is generally set at one to two percentage points above the FD rate, which means the effective net borrowing cost — after netting FD interest earnings against overdraft interest — is very low.
The overdraft limit is tied to the FD. It cannot exceed the FD maturity date, and if the FD is broken, the overdraft facility is cancelled. The credit limit does not grow over time — it is fixed at a percentage of the FD value, which itself is fixed until maturity.
LAMF as an Overdraft — Structure and Mechanics
A Loan Against Mutual Fund on Stashfin also operates as a revolving overdraft, but the collateral is your mutual fund portfolio rather than a fixed deposit. The credit line is based on the current NAV of your pledged units multiplied by the applicable LTV. Unlike an FD overdraft, the LAMF credit line is dynamic — as the NAV of your pledged portfolio grows over time, the available credit limit can increase at renewal.
The LAMF interest rate is typically higher in absolute terms than an FD overdraft rate, reflecting the higher risk associated with market-linked collateral. However, LAMF provides access to a larger credit line for investors whose mutual fund portfolio significantly exceeds their FD holdings.
Interest Rate Comparison
The OD against FD wins clearly on interest rate. The net cost of an FD overdraft — interest charged minus FD interest earned — is among the lowest of any credit product in India. For a borrower whose primary criterion is minimising borrowing cost, an FD overdraft is the right product when FD holdings are sufficient to cover the need.
LAMF interest rates are higher in absolute terms but significantly lower than unsecured alternatives. For borrowers who need a larger credit line than their FD can support, or who hold most of their liquid financial assets in mutual funds rather than deposits, LAMF offers a more cost-effective alternative to personal loans or credit cards despite its higher rate relative to FD overdrafts.
Credit Limit Comparison
The OD against FD is capped at 80 to 90 percent of the FD value. For an investor with a large mutual fund portfolio and a small FD holding, the FD overdraft provides only a fraction of the capital that LAMF could make available against the same financial position.
LAMF credit limits are based on the current market value of the entire pledged portfolio, which for long-term equity investors can be substantially larger than any FD holding. This makes LAMF the more relevant product for capital-intensive needs.
Collateral Risk Comparison
This is the most important difference between the two products from a risk management perspective. Fixed deposits do not fluctuate in value. An FD overdraft carries no margin call risk — the bank knows exactly what the collateral is worth at all times because it is guaranteed by the deposit terms. The borrower faces no risk of being asked to repay early due to collateral depreciation.
Mutual fund NAVs fluctuate daily. LAMF collateral — especially equity-oriented funds — can decline significantly during market corrections. When NAV falls and the outstanding loan approaches the LTV threshold, the lender issues a margin call. The borrower must respond by repaying part of the loan or pledging additional units. This is a genuine risk that requires active management and does not exist with FD overdrafts.
Tenure and Renewal
An FD overdraft tenure is bounded by the FD maturity. If your FD matures in eighteen months, your overdraft cannot extend beyond that. Renewal requires either rolling over the FD or creating a new FD and establishing a fresh overdraft.
LAMF is typically structured as an annual revolving credit line that can be renewed. The mutual fund portfolio has no maturity date, so LAMF can be renewed indefinitely as long as the portfolio is maintained and the loan terms are complied with. For long-term recurring liquidity needs, LAMF provides a more enduring credit infrastructure.
Which Product for Which Situation
Use an OD against FD when the borrowing need is modest and within your FD value, when the absolute lowest interest cost is the priority, when you want zero collateral risk, and when the tenure aligns with your FD maturity.
Use LAMF when your mutual fund portfolio is larger than your FD holdings and can support a bigger credit line, when you need a credit facility that can renew and grow with your portfolio over time, when flexibility of tenure is important, and when the purpose requires a larger credit line than an FD overdraft can provide.
For investors with both significant FD and mutual fund holdings, using FD overdrafts for smaller, short-term needs and LAMF for larger or longer-duration needs is a financially coherent approach that matches the right product to each situation.
Loan Against Mutual Fund is subject to applicable interest rates and credit assessment. Mutual fund units pledged as collateral are subject to market risks. Please read all loan-related documents carefully.
