Open-End Fund Singapore

Open-End Fund Singapore: How Unit Trusts and Mutual Funds Work

An open-end fund in Singapore is a pooled investment vehicle that issues new units to investors who buy in and cancels units when investors redeem — at the fund’s current net asset value (NAV). This contrasts with closed-end funds (like most S-REITs or investment trusts), which have a fixed number of shares trading on an exchange. The vast majority of unit trusts in Singapore are open-end structures. This is not financial advice.

How Open-End Funds Work

When you invest in an open-end fund, the fund manager uses your money to buy underlying assets (equities, bonds, REITs, etc.). Your investment is represented by units, priced at the NAV per unit — calculated by dividing total fund assets minus liabilities by the total units outstanding.

The fund issues new units when money flows in and redeems units when investors exit. This means the fund’s size fluctuates daily based on investor flows, unlike a closed-end fund whose share count is fixed at IPO.

Open-End Fund vs Closed-End Fund in Singapore

The key structural differences:

  • Open-end fund: Unlimited units; bought/sold at NAV; no secondary market discount or premium; liquidity provided by the fund itself
  • Closed-end fund: Fixed units at IPO; traded on exchange; can trade at a discount or premium to NAV; market price determined by supply and demand (e.g., S-REITs, business trusts)

S-REITs in Singapore are technically closed-end funds — their unit count is fixed unless they issue new units via rights issues or private placements. ETFs are a hybrid: they are open-end at the wholesale level (authorised participants create/redeem large blocks at NAV), but trade on exchanges like closed-end funds for retail investors.

Types of Open-End Funds Available in Singapore

  • Unit trusts (mutual funds): The most common open-end fund in Singapore, sold through banks, fund platforms (FSMOne, Endowus, Fundsupermart), and financial advisers. Regulated by MAS under the Code on Collective Investment Schemes
  • ETFs (exchange-traded funds): Open-end at the creation/redemption level; traded intraday on SGX for retail investors
  • Hedge funds / private funds: Often open-end structures restricted to accredited investors with quarterly or annual redemption windows

Costs of Open-End Funds in Singapore

Singapore open-end funds carry several layers of fees:

  • Sales charge (front-end load): Typically 1.5–3% when buying via banks; often 0% on direct platforms like Endowus or FSMOne
  • Annual management fee: 0.5–2% p.a. depending on fund type (lower for passive index funds, higher for active equity funds)
  • Total Expense Ratio (TER): All-in annual cost including management fee, trustee fee, and other expenses — disclosed in the fund’s Key Investor Information Document (KIID) and prospectus

For cost comparison, always use the TER rather than just the advertised management fee.

How to Invest in Open-End Funds in Singapore

Frequently Asked Questions

What is an open-end fund in Singapore?
An open-end fund issues and redeems units continuously at the current net asset value (NAV). Most Singapore unit trusts are open-end funds. The fund size grows when investors buy in and shrinks when they redeem, unlike closed-end funds with a fixed unit count.
What is the difference between an open-end fund and a closed-end fund?
Open-end funds transact at NAV with the fund directly; the unit count is unlimited. Closed-end funds (like S-REITs) have fixed units trading on an exchange and can trade at a discount or premium to NAV based on market demand.
Are ETFs open-end or closed-end funds?
ETFs are a hybrid. At the wholesale level they are open-end — authorised participants create and redeem large blocks of units at NAV. For retail investors, ETF units trade on the exchange like shares, meaning the market price can briefly diverge from NAV.
Can I use CPF to invest in open-end funds?
Yes. Approved unit trusts under the CPF Investment Scheme (CPFIS) can be purchased with CPF Ordinary Account funds. The approved list is maintained on cpf.gov.sg. Platforms like Endowus facilitate CPF and SRS fund investments with zero sales charges.
What fees should I check before investing in a unit trust in Singapore?
Check the Total Expense Ratio (TER), which includes the annual management fee, trustee fee, and other costs. Also check the sales charge (front-end load) — this can be 0% on direct platforms vs 2–3% at banks. Always read the fund’s prospectus and KIID before investing.
