What Is a Mutual Fund? A Plain Guide for Bangladeshi Investors

A mutual fund collects money from many investors and invests it as a single pool, managed by professionals. Each investor owns units representing their share of the pool. When the investments do well, the value of every unit rises. When they do badly, it falls.

That is the whole idea. The rest of this article explains how it works in practice in Bangladesh.

A simple example

Suppose a thousand people each put in BDT 10,000. The fund now has BDT 1 crore to invest — enough to buy shares in thirty different companies, or a spread of government bonds, or a mix of both.

None of those thousand people could have built that spread alone. With BDT 10,000 you might buy shares in one company. If that company does badly, you lose. In the fund, one company doing badly is diluted across twenty-nine others.

That is the first thing a mutual fund gives you: diversification you could not afford on your own.

The second is professional management — someone whose job is to research those companies, rather than you doing it in the evenings.

The third is liquidity — with an open-end fund you can get your money out without finding a buyer yourself.

Units and NAV

When you invest, you receive units. The price of one unit is its net asset value, or NAV.

NAV is calculated simply:

NAV per unit = (value of everything the fund owns − what it owes) ÷ number of units

If a fund's holdings are worth BDT 1,85,000, it owes BDT 5,000 in fees and expenses, and it has 15,000 units in issue, then:

(1,85,000 − 5,000) ÷ 15,000 = BDT 12.00 per unit

Every unitholder's stake is worth BDT 12 per unit, whoever they are and whenever they joined.

Two points that confuse newcomers:

A low NAV does not mean a cheap fund. A fund at BDT 12 is not better value than one at BDT 20. What matters is how much the NAV has grown since you bought, not the number itself.

The buy price and sell price may differ slightly from NAV, because of charges applied on entry or exit. Both are published, and both are derived from the latest calculated NAV.

Open-end and closed-end funds

Open-end funds have no fixed size and no maturity date. New units are created when people invest and cancelled when people redeem. You buy from and sell back to the fund itself, at NAV. There is no need to find a buyer.

Closed-end funds issue a fixed number of units for a fixed term. After the initial offer, units trade on the stock exchange like a company share. Because the price is set by supply and demand rather than by NAV, closed-end units often trade at a discount or premium to what they are actually worth.

For most first-time investors, open-end funds are the simpler proposition: the price you get is the fund's actual value, and you are not dependent on market sentiment for an exit.

Who does what

Three separate institutions are involved in every mutual fund in Bangladesh, and the separation is deliberate.

The AMC never holds your money. The custodian does. The trustee watches the AMC. No single party both decides and holds.

How mutual funds are kept safe in Bangladesh

Moving money from a fixed deposit into a mutual fund feels like a bigger step than it is, largely because the protections are invisible. Here is what actually stands behind your investment.

Every fund is registered with BSEC. Mutual funds in Bangladesh operate under the Mutual Fund Rules 2025, and a fund cannot raise money from the public without being registered with the Bangladesh Securities and Exchange Commission first.

Your units are recorded in your own name. Units are held either in dematerialised form in your own BO account, or as a paper unit certificate issued in your name. Either way the holding is recorded against you, not against the asset management company, and cannot be moved without your instruction.

Three institutions, three separate licences. The asset management company decides what to buy. The custodian holds the assets. The trustee supervises the AMC on behalf of unitholders. All three are separately registered with BSEC, and no one party both decides and holds.

The trustee's duty is to you, not to the fund manager. If an AMC breaches the trust deed or the fund's stated limits, the trustee is empowered to intervene. This is not a courtesy relationship — it is the trustee's legal obligation to unitholders.

Investment limits are binding, not aspirational. Each fund's constitutive documents set out what it may and may not hold, including limits on how much can go into any single company or sector. These are enforceable, not internal guidelines.

No fund may promise a return. Guaranteed returns are not permitted for mutual funds in Bangladesh. Anyone offering one is misrepresenting the product, and that is itself a warning sign worth acting on.

Accounts are audited and NAV is published. Funds file audited financial statements and publish net asset value on a regular schedule, so you can check what your holding is worth independently of what anyone tells you.

What none of this protects against: investment loss. These measures prevent your money being misappropriated. They do not prevent the market falling. Those are different risks, and only the first is engineered away.

Types of fund

Equity funds invest mainly in listed shares. Highest long-term potential, and the most volatile. Suited to money you will not need for many years. Ekush Growth Fund is an equity-oriented open-end fund.

Fixed-income funds invest in treasury bills and bonds, fixed deposits with banks, and corporate bonds. Steadier, with a lower ceiling. Suited to capital preservation and predictable income. Ekush Stable Return Fund invests exclusively in fixed-income securities.

Balanced funds hold both, shifting the mix as conditions change. Ekush First Unit Fund holds a balanced portfolio of equity and debt securities.

Shariah-compliant funds screen holdings against Islamic principles.

Mutual funds compared with FDR and Sanchayapatra

Most Bangladeshi savers arrive at mutual funds from one of these two, so the comparison is worth making honestly.

Fixed deposits give you a rate agreed in advance. You know exactly what you will get. Break it early and you usually forfeit part of the interest. Interest is taxed as interest income.

Sanchayapatra offers government-backed returns with defined tenures and purchase ceilings, and early encashment carries reduced rates.

Mutual funds do not promise a return. A fixed-income fund aims for stability but does not guarantee it, and an equity fund can fall in value. In exchange you get three things a deposit does not offer: exposure to market growth, no fixed tenure, and different tax treatment — returns arrive as capital gains and dividends rather than interest, which are taxed under separate rules.

Neither is universally better. A fixed deposit is the right instrument for money you need in eighteen months. An equity fund is the wrong one. For money you will not touch for a decade, the reverse is usually true.

Risks, stated plainly

Market risk. The value of your units can fall. Equity funds can fall substantially in a bad year.

No guaranteed return. No mutual fund in Bangladesh may promise a return, and any party suggesting otherwise is misrepresenting the product.

Concentration risk. A fund heavily weighted to one sector rises and falls with that sector.

Interest-rate risk. Bond prices move inversely to interest rates, so fixed-income funds are affected when rates shift.

Manager risk. Active funds depend on the judgement of the people running them. Track records vary, which is why comparing a fund against its benchmark matters.

How to start

• Complete registration with the asset management company — typically NID, photographs, a nominee's details and a bank cheque leaf, plus your e-TIN if you have one.
• Choose how you want to hold your units — dematerialised in a BO account, or as a paper unit certificate. A BO account is not mandatory.
• Submit a purchase application with payment.
• Receive confirmation of your unit allocation.

Having an e-TIN is not mandatory either, but the withholding rate on dividend income is lower if you have one. You can estimate your investment rebate with the tax calculator.

If you would rather invest a fixed amount every month than a lump sum, a Systematic Investment Plan applies the same fund mechanics on a monthly schedule.
