If you are looking for a simple, effective, and highly accessible way to grow your wealth, investing in Singapore’s top 30 blue-chip companies is an excellent starting point. For both investment beginners and those with basic market experience, understanding how to buy STI ETF in Singapore is a fundamental milestone. This comprehensive 2026 guide will walk you through everything you need to know—from understanding what the fund is, to comparing your options, executing your first trade, and building a long-term strategy for financial success.

What is the Straits Times Index (STI) ETF?

To understand the STI ETF, we first need to break down the acronym. "ETF" stands for Exchange-Traded Fund, which is a type of pooled investment security that you can buy and sell on a stock exchange just like an individual stock. The "STI" stands for the Straits Times Index, the benchmark index that tracks the performance of the top 30 largest and most liquid companies listed on the Singapore Exchange (SGX).

When you learn how to buy STI ETF in Singapore, you are essentially learning how to buy a single fund that mirrors this exact index. Instead of purchasing 30 different stocks individually—which would require significant capital and management—the STI ETF offers you a diversified slice of the entire Singapore stock market through a single, convenient purchase.

Key Benefits of Investing in the STI ETF

Investing in the STI ETF comes with several core advantages, especially for those who want a hands-off approach to wealth accumulation:

• Instant Diversification: By holding one unit of the ETF, you instantly gain exposure to leading industries. For instance, the fund is heavily anchored by the Financial Services sector (57.23%), alongside Industrials (15.16%) and Real Estate (14.65%). You instantly own fractions of local giants like DBS Group Holdings, Oversea-Chinese Banking Corp (OCBC), and United Overseas Bank (UOB).

• Low-Cost Market Access: Buying 30 individual blue-chip stocks would incur massive brokerage commissions. An ETF bundles these together, allowing you to invest with significantly lower transaction and management fees.

• High Liquidity: Many SGX-listed ETFs, particularly popular index and commodity ETFs, offer high liquidity. Top products regularly trade millions of shares daily, enabling investors to buy or sell units easily at market prices. Liquidity varies by ETF, with niche products typically seeing lower volumes.

• Simplicity and Peace of Mind: There is no need to analyze individual balance sheets or attempt to pick winning stocks. The ETF automatically adjusts to mirror the top 30 companies, saving you time and reducing the stress of active stock picking.

The Two STI ETFs in Singapore: A 2026 Comparison

When researching how to buy STI ETF in Singapore, you will quickly discover that there are two primary options available on the Singapore Exchange (SGX). Both aim to replicate the exact same index, but they are managed by different financial institutions. These are the SPDR STI ETF (ticker symbol: ES3) and the Nikko AM Singapore STI ETF (ticker symbol: G3B).

SPDR Straits Times Index ETF (ES3)

The SPDR Straits Times Index ETF (ES3) is the older and more established of the two funds. It is managed by State Street Global Advisors (specifically, State Street Global Adv Singapore Ltd), with State Street Bank & Trust Co acting as the trustee. Listed on April 11, 2002, this fund has a long and resilient track record of tracking the FTSE/SGX STI TR SGD index. It operates within the limits set out in the CPF Investment Guidelines, making it a staple for many local retirement portfolios.

Nikko AM Singapore STI ETF (G3B)

The alternative option is the Nikko AM Singapore STI ETF (G3B). This fund is managed by Nikko Asset Management. Like its SPDR counterpart, it is designed to track the exact same top 30 blue-chip companies on the SGX. It offers investors a slightly different management structure but serves the exact same core purpose: providing broad, diversified exposure to the Singapore market.

ES3 vs. G3B: Key Differences for Investors in Singapore

While both funds track the same index, they have distinct operational metrics. Below is a comparative analysis based on the latest 2026 market data to help you make an informed decision based on cost and scale.

Note: As of June 2, 2026, the SPDR STI ETF (ES3) currently boasts a massive AUM of 3.24 Billion SGD, reflecting strong institutional and retail trust. Furthermore, the accessible board lot size of just 1 unit means investors can start with as little as the price of a single share (e.g., around 5.18 SGD).

Getting Started: What You Need to Buy STI ETFs

Before you can execute your first trade, there are a few administrative steps you must complete. Bridging the gap between knowing what an ETF is and actually owning one requires setting up the right accounts.

Opening Your Central Depository (CDP) Account

In Singapore, the Central Depository (CDP) account acts as your personal digital safe for investments. Operated by the SGX, the CDP account is the secure repository where all the stocks, bonds, and securities you buy on the open market are legally held under your name. While some modern brokerages offer "custodian" accounts (where the broker holds the shares on your behalf), opening a direct CDP account is highly recommended for beginners as it gives you direct ownership and voting rights for your investments. To make managing your investments easier, some modern brokers like Moomoo SG offer one-click CDP Linkage. This feature allows you to view your CDP-held shares, dividends, and records directly within the trading app, creating a unified and seamless experience so you can manage your trading and holdings all in one place.

Choosing a Brokerage Account to Buy Your ETF

While the CDP account holds your shares, you cannot buy them directly from the CDP. You need a stockbroker account, which serves as the trading platform to execute your buy and sell orders. When choosing a broker, you should prioritize low commission fees, intuitive platform usability, and robust customer support. Another key factor is the speed and ease of account opening; you don't want to be stuck filling out manual forms. Modern platforms like Moomoo SG allow Singapore residents to use Singpass for a fully online application, which can get your account approved in minutes. This makes figuring out how to buy STI ETF in Singapore incredibly straightforward.

How to Buy STI ETF in Singapore: A Step-by-Step Guide

Now that your accounts are ready, it is time to make your purchase. This is the core of our guide. Follow these numbered steps to confidently navigate your brokerage platform and execute your first trade.

Step 1: Fund Your Brokerage Account

Before you can buy units of the ETF, you need capital in your brokerage account. Most platforms in Singapore make this process instantaneous. You can deposit funds using PayNow, FAST (Fast and Secure Transfers), or standard bank transfers. Simply link your local bank account to your brokerage, enter the desired investment amount, and initiate the transfer. For example, setting up a Direct Debit Authorisation (DDA) on the moomoo app can allow your funds to arrive in as little as 5 minutes. Once the funds are reflected in your brokerage balance, you are ready to trade.

Step 2: Search for the STI ETF Ticker (ES3 or G3B)

Log into the moomoo app or desktop platform and locate the search bar. If you have decided to purchase the SPDR fund, type in the unique stock ticker symbol ES3. If you prefer the Nikko AM fund, type in G3B. Clicking on the ticker will bring up the fund's real-time quotes data, historical candlestick charts, and current market price.

Step 3: Place Your Buy Order (Limit vs. Market Order)

Click the "Buy" or "Trade" button. You will now be asked to choose an order type. Demystifying this step is crucial for beginners:

• Market Order: This tells your broker to buy the ETF units immediately at the best available current market price. This guarantees the trade will happen quickly, but the final price might fluctuate slightly from what you see on the screen due to real-time market movements.

• Limit Order: This allows you to set a specific maximum price you are willing to pay. For example, if ES3 is trading at SGD 5.18, you can place a Limit Order at SGD 5.15. Your broker will only execute the trade if the price drops to SGD 5.15. This gives you price control but does not guarantee the order will be filled if the market price keeps rising.

For highly liquid assets like the STI ETF, both methods are viable, though beginners often use Limit Orders for precise budgeting. Enter the quantity you wish to buy (remembering the lot size is just 1 unit) and proceed.

Step 4: Confirm Your Purchase and Monitor Your Investment

Review your order details carefully, including the estimated fees, and click "Confirm" or "Submit." Once the market matches your order, it will be marked as "Filled." You can now navigate to your platform’s "Portfolio" or "Assets" tab to view your newly acquired ETF units. Over the next few days, if you linked a CDP account, you will also see the units securely deposited there.

Investment Strategies for the STI ETF

Understanding how to buy STI ETF in Singapore is just the mechanical first step. To truly build wealth, you must apply a strategic approach to your investments. Here are two popular methodologies to consider.

Lump-Sum Investing vs. Dollar-Cost Averaging (DCA)

When you have capital ready to deploy, you face a choice: invest it all at once or spread it out.

• Lump-Sum Investing involves taking a large amount of cash and buying ETF units in one single transaction. Statistically, because markets tend to rise over the long term, investing your money as soon as possible often yields higher returns. However, it requires a high risk tolerance, as a sudden market dip right after your purchase can be emotionally taxing.

• Dollar-Cost Averaging (DCA) involves investing a smaller, fixed amount of money at regular intervals (e.g., 500 SGD every month), regardless of the ETF's price. When the price is high, your 500 SGD buys fewer units; when the price drops, it buys more. This systematically lowers your average cost per unit over time and completely removes the stress of trying to "time the market."

To execute a DCA strategy without the manual chore of remembering to invest every month, you can use an automated feature like a Regular Savings Plan (RSP). This bridges the gap between theory and practice. Platforms like Moomoo SG offer an RSP feature for assets like the STI ETF, allowing you to automatically invest a fixed amount at set intervals (e.g., weekly or monthly). This enforces investment discipline and turns your long-term strategy into a simple, set-and-forget process. You can explore setting up an RSP on the moomoo app to start building your portfolio consistently.

Reinvesting Your Dividends for Compounded Growth

The STI ETF is renowned for its dividend distributions. Instead of withdrawing these cash payouts to spend, a powerful wealth-building strategy is to reinvest them by buying more ETF units. This triggers the effect of compound interest—your dividends buy more units, which in turn generate even more dividends in the next payout cycle. Over a 10-to-20-year horizon, dividend reinvestment can drastically multiply your overall portfolio size.

Understanding the Costs of Buying and Holding STI ETFs

Transparency regarding fees is essential. Every dollar paid in fees is a dollar subtracted from your potential returns. Here is a breakdown of the costs associated with buying and holding the STI ETF.

Brokerage Commission Fees

Every time you execute a buy or sell order, your stockbroker will charge a one-time transaction fee. Thanks to modern digital brokerages, these commission fees have plummeted in recent years, often costing just a few dollars or a small percentage of your total trade value. Always check your broker's fee schedule before trading. To make investing even more accessible, some platforms offer promotional rates that can significantly reduce your costs.

For instance, new users on Moomoo SG can enjoy zero-commission trading on Singapore stocks and ETFs for a full year, which makes strategies like Dollar-Cost Averaging even more cost-effective by eliminating a core trading cost on every purchase.

ETF Management Fees (Total Expense Ratio)

As professionally managed investment products, ETFs come with annual operating fees known as the Total Expense Ratio (TER). The fees are deducted directly from the fund’s net asset value with no out-of-pocket payment required from investors.

ETFs are widely recognised for their cost efficiency, especially when compared to actively managed mutual funds that have higher annual expenses.

Other SGX-related Fees (Clearing & Trading Fees)

Finally, all trades executed on the Singapore Exchange are subject to small, mandatory institutional fees. These include an SGX Clearing Fee and an SGX Trading Fee, which amount to a tiny fraction of a percent (typically around 0.04% combined). Additionally, the prevailing Goods and Services Tax (GST) is applied to your brokerage commissions and SGX fees.

STI ETF Performance & Dividend History (Updated 2026)

To set realistic expectations, it is vital to look at historical data. The STI ETF is designed as a long-term investment, weathering various economic cycles to provide steady growth and income.

Analysing Historical Price Performance

The STI ETF has shown remarkable resilience and steady growth over the long term. As of mid-2026, the SPDR STI ETF (ES3) reported a robust 10-year annualized return of 10.03%. In the medium term, the fund achieved a 5-year return of 14.21% and an impressive 3-year return of 21.41%.

This strong performance is largely anchored by Singapore's robust banking sector. With DBS Group Holdings making up 26.63% of the fund, OCBC at 16%, and UOB at 9.66%, the financial sector’s stability drives the index. Even when individual stocks face headwinds—such as Singtel (6.54% holding) navigating softer share prices despite record dividends—the diversified nature of the ETF ensures the overall portfolio remains insulated from single-company shocks.

A Look at STI ETF Dividend Payouts

For investors seeking passive income, the STI ETF is probably an attractive asset. The SPDR STI ETF (ES3) distributes dividends semi-annually, typically in February and August.

Historically, the fund has maintained a consistent and generous payout schedule. For example, investors received a cash dividend of 0.085 SGD per share in February 2026, following payouts of 0.089 SGD in August 2025 and 0.091 SGD in February 2025. As of mid-2026, the trailing twelve months (TTM) dividend yield stands at a healthy 3.36%. This reliable stream of semi-annual income makes the STI ETF a cornerstone for dividend-focused investors in Singapore.
