Why Singapore Investors Are Flocking to S&P 500 ETFs

Why Singapore Investors Are Flocking to S&P 500 ETFs

Marcus Chen, 28, works as a software engineer in Singapore. Like many Singaporeans, he started his investment journey with CPF contributions and a handful of Singapore REITs. But unlike his colleagues who kept all their money in local equities, Marcus wanted diversification beyond the 30 companies on the Straits Times Index. He wanted exposure to the biggest companies in the world: Apple, Microsoft, NVIDIA, Amazon, and Google.

In January 2024, Marcus opened a brokerage account with Interactive Brokers and invested his first USD 500 into CSPX, the UBS-issued S&P 500 ETF listed on the London Stock Exchange. Eighteen months later, his investment has returned over 30%, outperforming his STI holdings significantly. More importantly, he now has a natural hedge against Singapore’s concentrated market.

Marcus is not alone. According to data from the Monetary Authority of Singapore, Singapore investors’ appetite for US equities has grown substantially, with retail participation in foreign securities reaching record levels in 2024 and 2025. The appeal is obvious: the S&P 500, which tracks 500 of the largest US companies, has delivered average annual returns of approximately 10-12% over the past several decades, significantly outperforming most developed market indices.

What Is an S&P 500 ETF and How Does It Work?

An S&P 500 Exchange-Traded Fund is a fund that tracks the S&P 500 index, which comprises 500 of the largest publicly traded companies in the United States across sectors like technology, healthcare, finance, and consumer goods. When you buy shares of an S&P 500 ETF, you are essentially buying a tiny ownership stake in all 500 companies simultaneously.

The appeal for S&P 500 ETF Singapore investors is straightforward: with a single purchase, you get instant diversification across America’s top corporations. You do not need to analyze individual stocks, worry about single-company bankruptcy, or try to pick winning stocks. The index does the work for you.

As passive investing pioneer John Bogle famously said: “Don’t do something, just stand there.” This philosophy has proven remarkably effective for S&P 500 investors over the long term.

CSPX vs IWDA vs SXR8 vs SPY vs VOO: The Main Contenders

Singapore investors have access to several S&P 500 ETFs through international brokers. For S&P 500 ETF Singapore residents specifically, these funds provide one of the simplest paths to US equity exposure. Here is how S&P 500 ETF Singapore investors can compare the main options:

1. CSPX (UBS MSCI USA Swap UCITS ETF)

CSPX is currently the most popular S&P 500 ETF among S&P 500 ETF Singapore investors, and for good reason. It offers one of the lowest ongoing charges among accumulating S&P 500 ETFs at just 0.05% per year. The fund uses a physical replication strategy, meaning it actually holds the underlying stocks in the index. CSPX is USD-hedged in its accumulating share class, making it attractive for SGD-based investors who want to avoid currency volatility eating into returns.

Key facts about CSPX:

• ISIN: IE00B4L5Y983
• Ongoing charge: 0.05%
• Distribution: Accumulating (reinvests dividends)
• Currency: USD
• Exchange: London Stock Exchange
• Physical replication: Yes

2. IWDA (iShares MSCI World UCITS ETF)

IWDA differs from CSPX in one crucial way: it tracks the MSCI World Index, not the S&P 500. The MSCI World includes companies from 23 developed markets, including the United States, Europe, Japan, and Australia. About 70% of IWDA’s holdings are US companies, so you get significant S&P 500 exposure, but also built-in global diversification.

The trade-off is slightly higher volatility and US exposure that is closer to 70% rather than 100%. IWDA’s ongoing charge of 0.20% is higher than CSPX, but for investors who want a one-stop global equity ETF, IWDA is compelling.

• ISIN: IE00B4L5YC18
• Ongoing charge: 0.20%
• Distribution: Accumulating
• Currency: USD
• Exchange: London Stock Exchange

3. SXR8 (SPDR S&P 500 UCITS ETF)

SXR8 is the SPDR-branded S&P 500 ETF and one of the oldest and most established ETFs in the world. It offers physical replication of the S&P 500 with an ongoing charge of 0.03%, making it the cheapest option on this list. SXR8 is accumulating, meaning dividends are reinvested automatically.

The main consideration for Singapore investors is currency: SXR8 trades in EUR on European exchanges, so you will need to account for EUR/USD exchange risk if you are buying in SGD through Interactive Brokers or Saxo. Some brokers may also charge higher trading fees for EUR-denominated securities.

• ISIN: IE00B6YX5C33
• Ongoing charge: 0.03%
• Distribution: Accumulating
• Currency: EUR
• Exchange: London Stock Exchange, Deutsche Borse

4. SPY (SPDR S&P 500 ETF Trust)

SPY is the original S&P 500 ETF, created in 1993 and still the most liquid ETF in the world with daily trading volumes in the billions of USD. It tracks the S&P 500 precisely and is an excellent choice for active traders who need instant liquidity. However, SPY distributes dividends quarterly rather than reinvesting them, and its ongoing charge of 0.09% is higher than CSPX or SXR8.

For Singapore-based investors using CPF or SRS accounts, SPY is not typically available as a CPF or SRS investment, limiting its appeal compared to accumulating ETFs in a UCITS wrapper. Learn more about how to invest in S&P 500 from Singapore.

• ISIN: US78462F1030
• Ongoing charge: 0.09%
• Distribution: Quarterly dividends paid out
• Currency: USD
• Exchange: NYSE Arca

5. VOO (Vanguard S&P 500 UCITS ETF)

VOO is Vanguard’s S&P 500 ETF and one of the most respected funds in the world. It offers physical replication with an ongoing charge of 0.07%, and like CSPX, it is accumulating. VOO is available on the London Stock Exchange and is popular among buy-and-hold investors who want the Vanguard brand’s reputation for low costs and reliable indexing.

For Singapore investors buying through Interactive Brokers, VOO USD accumulating (VUAA) on LSE is accessible. The combination of Vanguard’s brand strength and a competitive 0.07% fee makes VOO a solid core holding for any S&P 500 allocation.

• ISIN: IE00BFMXXD54
• Ongoing charge: 0.07%
• Distribution: Accumulating
• Currency: USD
• Exchange: London Stock Exchange

How to Buy S&P 500 ETFs from Singapore

Singapore investors can purchase these ETFs through several brokerage platforms that support international markets:

• Interactive Brokers (IBKR): Offers the widest range of ETFs on LSE, NYSE, and European exchanges with competitive USD trading fees. Minimum trade is typically USD 1. No CPF or SRS integration, but you can use SGD cash accounts.
• Saxo Markets: Good platform with access to LSE and NYSE. Offers a wide range of ETFs. Has SRS account integration for SRS-funded investments.
• FSMS Invest: Singapore-based broker focused on US and Singapore stocks. Good for investors who want a local platform experience.

The process is straightforward: open a brokerage account, fund it with SGD or USD, search for the ETF ticker (CSPX, IWDA, SXR8, VOO), and place your order. For SRS investors, check with your broker which ETFs are pre-approved for SRS investment before committing funds.

Tax Implications for Singapore Investors

One of the major advantages of investing in US ETFs as a Singapore resident is the absence of capital gains tax. Singapore does not tax capital gains, so when your S&P 500 ETF appreciates in value, you do not owe any tax to IRAS on those gains.

However, there are a few tax considerations to keep in mind:

• Dividend withholding tax: US-source dividends are subject to a 30% withholding tax when paid to foreign investors. However, Singapore’s extensive tax treaty with the United States typically reduces this to 15% for eligible investors. This tax is withheld at source and cannot be avoided.
• Estate tax: US estate tax may apply to Singapore residents holding more than USD 60,000 in US securities at death. For most retail investors this threshold is not an issue, but high-net-worth individuals should consult a tax advisor.
• SRS tax treatment: If you invest through your SRS account, contributions enjoy tax relief. Check the current SRS scheme rules for contribution limits and eligible investments.

How Much Should You Allocate to S&P 500?

There is no one-size-fits-all answer. A common framework used by financial advisors is the 100 minus your age rule: at age 30, you might allocate 70% of your portfolio to equities, with a significant portion in US equities for growth. At age 50, the allocation shifts toward more conservative instruments.

For Singapore investors specifically, consider these factors:

• CPF OA allocation: If you are using CPF OA to invest in ETFs, you are already getting Singapore and Asia-Pacific equity exposure. S&P 500 allocation via SRS or cash brokerage adds US diversification.
• Currency risk: All S&P 500 ETFs trade in USD or EUR, so SGD-based investors bear exchange rate risk. A weakening USD against SGD reduces returns when converted back.
• Time horizon: Younger investors with 20+ year horizons can afford to take more equity risk and benefit from S&P 500’s long-term growth trajectory.
