Unit trust vs fixed deposit in Sri Lanka
In short
A fixed deposit is a contract: the bank agrees a rate in advance and returns your capital at maturity, and the bank carries the risk of what it does with the money. A unit trust is ownership of a pool of assets, so its value moves with what the pool holds and no rate is promised. The practical difference is who carries the risk, and whether you can get the money out early without penalty.
This is the comparison almost every Sri Lankan saver makes, and it is usually presented by someone who sells one of the two. We sell neither: we publish prices for all 89 licensed unit trusts and have no deposit product at all.
The two are not competing versions of the same thing. They are different legal structures with different promises attached, and most of the confusion comes from comparing their headline percentages as though those numbers mean the same thing. They do not.
Side by side
What each one actually is, rather than what each returned.
| Unit trust | Fixed deposit | |
|---|---|---|
| What is promised | Nothing. You receive whatever the assets earn, after fees | A stated rate, agreed before you deposit |
| Who carries the investment risk | You do | The bank does, up to its own solvency |
| Capital at maturity | No maturity; value moves daily | Returned in full, subject to the bank |
| Getting money out early | Usually any business day; some funds charge an exit fee inside the first year | Usually possible with a penalty or a reduced rate |
| Term | Open-ended, no fixed term | Fixed, chosen up front |
| Cost | An annual management fee, deducted before the unit price is struck | No explicit fee; the bank keeps the margin |
| Regulator | Securities and Exchange Commission of Sri Lanka | Central Bank of Sri Lanka |
| Where the money goes | Published: each fund states what it holds | The bank lends it on at its own discretion |
The promise is the whole difference
A fixed deposit is a contract between you and a bank. The rate is agreed in advance, so you know at the outset what you will have at the end, and the bank takes the risk of earning more or less than it pays you. A unit trust is not a contract for a return. You buy units in a pool of assets, the pool earns whatever it earns, and after the management fee that is what reaches you. Nobody has promised you anything, and no fund on this site guarantees your capital.
Which is why the headline percentages are not comparable
An FD rate is forward-looking and contractual: it is what you will be paid. A unit trust return is backward-looking and descriptive: it is what the fund did over a stated past window. Putting them side by side compares a promise with an outcome. The honest way to read a fund figure is as evidence about how the fund has behaved, not as a rate you are being offered — which is why every return on this site carries the window and the date that produced it.
The rate environment both sit inside
Neither instrument exists in isolation: both ultimately depend on what short-term money earns in Sri Lanka. As at 25 August 2026, the Central Bank's Overnight Policy Rate was 8.75%, the 12-month treasury bill yielded 9.67% and the 3-month bill 9.06%, with CCPI inflation at 7.3% year on year and the average weighted prime lending rate at 10.86%. Money market funds hold instruments of exactly that kind, so their returns track those yields closely. Banks price deposits against the same environment but keep a margin, which is the spread they earn for taking the risk you are handing them.
Liquidity is where the practical difference usually shows up
Breaking a fixed deposit early normally costs you: the bank pays a reduced rate or charges a penalty, and the terms are set in the deposit agreement. Most Sri Lankan money market and income funds accept redemption requests on any business day and settle within a few working days. Several charge an exit fee on redemptions inside the first year, and the gap between a fund’s buying and selling price is also a real cost. Both figures are published on every fund page here.
Tax
Tax treatment differs between deposits and unit trusts in Sri Lanka, and it has changed more than once in recent years. We do not publish tax rates here, because a rate that is wrong or out of date is worse than no rate at all on a page people may act on. Check the current position with the Inland Revenue Department or a qualified tax adviser, and ask the fund manager how distributions from the specific fund are treated before you assume.
What can actually go wrong, in each
- Fixed deposit: the bank fails. Deposit insurance in Sri Lanka covers a limited amount per depositor per institution; above that you are an unsecured creditor.
- Unit trust: the assets the fund holds fall in value, or an issuer it lent to defaults. The unit price falls and there is no counterparty who owes you the difference.
- Fixed deposit: inflation outruns the rate you locked in, and the fixed sum you get back buys less than you expected.
- Unit trust: you need the money during a period when the price is down, and you realise that fall by selling.
What this page does not do
It does not tell you which of the two to choose. That depends on when you need the money, what else you hold, your tax position and how you would feel if the value fell, none of which we know. CeylonFunds is not a licensed investment adviser and does not provide investment advice. What this page can do is state precisely what each instrument promises and what it does not, so that the comparison you make is between the right two things.
Common questions
Is a unit trust safer than a fixed deposit in Sri Lanka?
They carry different risks rather than more or less of one risk. With a fixed deposit the bank promises a rate and carries the investment risk, so your exposure is to that bank failing. With a unit trust you own a share of the assets, so your exposure is to those assets falling in value. A money market fund holding treasury bills and a deposit at a small finance company are not ordered on a single safety scale.
Can I lose money in a unit trust?
Yes. The unit price can fall, and no fund on this site guarantees your capital. Money market funds are the category whose price moves least, and this site publishes a measured volatility figure and the largest peak-to-trough fall for every fund we hold enough prices for, precisely so that "how much does this actually move" is a number rather than an adjective.
Which gives a higher return, a unit trust or a fixed deposit?
Neither can be known in advance, which is the point. An FD rate is what you will be paid; a fund return is what a fund did in the past. We publish fund figures with the window and the date attached and do not publish deposit rates, because we do not collect them and a representative rate we made up would be misleading.
Can I withdraw from a unit trust before a fixed term?
There is no fixed term. Most Sri Lankan open-ended funds accept redemption requests on any business day and settle within a few working days, subject to the fund’s own terms. Check the exit fee on the fund page and in the prospectus: several funds charge on redemptions inside the first year.
Do I need a lot of money to start a unit trust?
No. Across the funds we track, minimum initial investments run from a few hundred rupees upward, and the current lowest minimums are listed on our rankings page. The minimum is set by each fund manager and can change.
This is general information about how two kinds of product differ. It is not advice about your circumstances, CeylonFunds is not a licensed investment adviser, and we do not publish bank deposit rates. Central Bank figures quoted are as at 25 August 2026.
