Here is a situation that catches a lot of people out. You have LKR 2,000,000 locked in a fixed deposit that matures in four months, and a bill for LKR 500,000 lands on your desk today. The instinct is to break the deposit. Almost always, that is the expensive choice. The cheaper one is to borrow against the deposit and leave it untouched โ and most people in Sri Lanka do not realise the option exists.
How a loan against a fixed deposit works
When you borrow against an FD, the bank lends you money using your own deposit as security. The deposit stays in place and keeps earning its full agreed interest; you simply have a loan or an overdraft sitting alongside it. Because the bank already holds your money as collateral, there is almost no risk to it, so approval is quick, paperwork is minimal, and the interest rate is low. Banks in Sri Lanka typically lend up to around 80โ90% of the deposit's value, either as a term loan or as an overdraft on your current account.
Why it beats breaking the deposit โ in numbers
Say your LKR 2,000,000 deposit is earning 10% and has four months left to run. Break it early and the bank applies its premature-withdrawal rate โ often several percentage points lower, and applied to the whole period โ so you can lose the better part of a year's interest, easily LKR 100,000 or more, and the deposit is gone.
Now borrow LKR 500,000 against it instead. The bank charges your deposit rate plus a small margin โ commonly around 2โ3% โ so perhaps 12โ13% on the LKR 500,000 you actually use, for the few months until your deposit matures. That might cost you on the order of LKR 15,000โ25,000 in interest. Meanwhile your full LKR 2,000,000 keeps earning 10%. When the deposit matures you settle the loan and keep the rest. You have spent a small, known amount to avoid forfeiting a much larger one. Unless you need the cash for a very long time, borrowing against the FD wins comfortably.
Term loan or overdraft?
Two formats are common, and the difference matters. A term loan gives you the whole amount up front and you repay on a schedule. An overdraft attaches a limit to your current account, and you pay interest only on what you actually draw and only for the days you use it. If your need is uncertain or short-term โ covering a gap that might resolve itself โ the overdraft is usually cheaper, because you are not paying interest on money you end up not using. For a fixed, known expense, a term loan is straightforward. Ask the bank which it is offering and pick the one that matches how you will actually use the money.
When this is the right move
- Short-term cash needs you can repay within months โ a medical bill, school fees, a temporary shortfall.
- When the deposit is close to maturity and breaking it now would waste almost all the interest you have earned.
- As a cheaper alternative to a personal loan or credit card, since the secured rate is far below unsecured borrowing.
What to check before you sign
Confirm the exact margin charged over your deposit rate, and whether it is a term loan or an overdraft. Ask the maximum percentage of the deposit you can borrow, and whether there is a processing fee. Most importantly, understand what happens at maturity: if the loan is still outstanding, the bank will normally settle it directly from the deposit and release the balance to you. That safety net is precisely why the rate is so low โ and why, used sensibly, a loan against your fixed deposit is one of the cheapest ways to raise cash in Sri Lanka without giving up the interest you have been patiently earning.
