How to Buy and Invest in S&P 500 ETFs in Singapore: A Complete Guide to Index Funds

Investing in the S&P 500, one of the world's most renowned stock market indices, has long been a favored strategy for those looking to gain exposure to the US equities market. The S&P 500, officially known as the Standard & Poor’s 500, tracks the stock performance of 500 of the largest companies listed in the United States.

Widely regarded as a key indicator of the US stock market's health, the S&P 500 represents about 80% of the US stock market’s value. While you cannot invest directly in the index, you can invest in Exchange-Traded Funds (ETFs) or mutual funds that mimic its performance.

Historically, the S&P 500 has demonstrated impressive long-term returns. From 1957, the index delivered an average annualized return of approximately 10.06%, including dividends. To illustrate, an investment of $10,000 made at the start of 1957 would have grown to about $96,000 by September 2025, assuming dividends were reinvested. This underscores the resilience and growth potential of the S&P 500 over time.

Today, Singaporean investors have numerous options to invest in the S&P 500, including exchange-traded funds (ETFs) and index funds accessible through local brokerage platforms. This guide aims to simplify the process, assisting both new and seasoned investors in navigating their way to successful S&P 500 investments.

What is the S&P 500

The S&P 500 index is composed of 500 leading U.S. companies from various sectors, including ITs, financials, healthcare, industrials and more. It is widely regarded as a benchmark for the overall health of the U.S. stock market and represents approximately 80% of the U.S. market capitalization. As of August 2026, the S&P 500 index's total market capitalization has reached approximately $67.8 trillion USD, reflecting a significant rise driven by strong large-cap U.S. equity gains and record highs past the 7,700 level. This follows a strong trajectory from year-end 2025 ($61.1 trillion USD) and late 2025 ($56.85 trillion USD), highlighting the continued growth and market concentration of the benchmark index.  

Information technology (IT) stocks have a significant presence in the S&P 500, with the top companies being tech giants like Microsoft, Apple, Nvidia, Amazon, and Meta (formerly Facebook). These companies reflect the growth drivers of the U.S. economy.

• iShares Core S&P 500 ETF (IVV)
• Vanguard S&P 500 ETF (VOO)
• iShares Core S&P 500 UCITS ETF (CSPX)

Selecting the ETF to invest in

With over 100 ETFs tracking the S&P 500, choosing the right one can be challenging. Here are the top ETFs to consider for Singaporean investors:

* as of 13 July 2026

Local option on the Singapore Exchange (SGX)

For those who prefer to avoid international markets, the S27 SPDR® S&P 500 ETF is available on the Singapore Exchange (SGX). This is the only local option for investing in an S&P 500 ETF.

Key factors to consider when choosing an ETF

• Expense Ratio: The expense ratio measures how much of a fund's assets are used for administrative and other operating expenses. Lower expense ratios are generally better for long-term investments. Typical S&P 500 ETFs have expense ratios ranging from 0.03% to 0.09%.
• Liquidity: Higher liquidity ensures that you can buy and sell your ETF shares easily without significant price changes.
• Domicile: The domicile two effects on ETFs: the dividend withholding tax and the tracking error. Singapore does not impose a withholding tax on dividends from locally listed ETFs. However, investing in U.S. ETFs incurs a 30% dividend withholding tax. Irish-domiciled ETFs offer a reduced 15% withholding tax due to tax treaties. When it comes to tracking error, US-listed ETFs will track the performance of the S&P 500 better than non-US-listed ETFs.
• Foreign Currency Risk: Investing in ETFs denominated in foreign currencies exposes you to currency fluctuation risks.
• Accumulating vs. Distributing ETFs: Accumulating ETFs reinvest dividends to increase the fund’s value, suitable for long-term growth. Distributing ETFs pay dividends to investors, providing a steady income stream.

Buying S&P 500 ETF

When it comes to investing in the S&P 500 from Singapore, investors have the option to choose between ETFs listed on the Singapore Exchange (SGX) and those listed on the New York Stock Exchange (NYSE). Each option comes with its own set of advantages and considerations, particularly in terms of trading volume, fund size, and investment platforms.

SGX-Listed S&P 500 ETF (Ticker: S27)

The S27 ETF, managed by State Street Global Advisors, is listed on the Singapore Exchange and provides a convenient option for local investors. One of the primary advantages of S27 is that it can be purchased using Supplementary Retirement Scheme (SRS) funds, which is not possible with most NYSE-listed ETFs. This feature makes it an attractive choice for Singaporean investors looking to utilize their SRS contributions.

However, it is important to note that the S27 ETF has a significantly lower trading volume compared to its counterparts on the NYSE. Lower trading volume can lead to wider bid-ask spreads, making transactions slightly more costly and potentially more difficult to execute at desired prices. Additionally, the minimum board lot size for S27 is 10 units, which may require a higher initial investment compared to NYSE-listed ETFs that typically have a minimum lot size of 1 unit.

NYSE-Listed S&P 500 ETFs

Investors also have the option to buy NYSE-listed S&P 500 ETFs, such as SPDR S&P 500 ETF Trust (SPY), iShares Core S&P 500 ETF (IVV), and Vanguard S&P 500 ETF (VOO). These ETFs are known for their high liquidity, with trading volumes in the tens of millions. The high liquidity of these ETFs ensures that investors can buy and sell shares easily with minimal price impact, benefiting from tighter bid-ask spreads.

NYSE-listed ETFs also tend to have lower minimum investment requirements, with most allowing purchases of as little as one share. This makes them more accessible to investors with smaller amounts of capital. Furthermore, while both SGX-listed and NYSE-listed ETFs are subject to the same 30% U.S. dividend withholding tax, investing through a platform like StashAway can offer additional benefits.

US Tax Implications for Singapore Investors: Estate Tax & Withholding Tax

• Ireland-Domiciled UCITS ETFs (CSPX, VUAA, SPYL): Ireland has a tax treaty with the US, cutting the dividend withholding tax rate to 15%. Furthermore, accumulating ETFs automatically reinvest dividends inside the fund without extra trading commissions.

B. US Estate Tax Exposure (Up to 40%)

• US-Domiciled ETFs: Non-US residents holding over US$60,000 in US-domiciled assets (including VOO or SPY) at death face progressive US Estate Tax rates ranging from 18% to 40%.
• Ireland-Domiciled UCITS ETFs: Overseas funds domiciled in Ireland are not considered US-situs assets. They carry 0% US estate tax risk for non-US investors.

• Reduces Impact of Volatility: DCA spreads out your investments over time, which can reduce the impact of market volatility. You buy more shares when prices are low and fewer when prices are high, potentially lowering your average cost per share.
• Disciplined Investment Approach: Regular investing helps build a disciplined approach, encouraging you to invest regardless of market conditions.

Reinvesting dividends

Reinvesting dividends can significantly enhance your returns over time. Many S&P 500 ETFs offer dividend reinvestment plans (DRIPs), which automatically use the dividends paid out by the ETF to purchase additional shares. This can compound your returns, as the reinvested dividends themselves generate additional earnings.

Diversification

While S&P 500 ETFs provide diversification within the U.S. market, consider diversifying your portfolio further by including stocks, bonds, and other asset classes. This broader diversification can help mitigate risks specific to the U.S. market and improve your overall risk-adjusted returns.

Tax-efficient investing

Consider the tax implications of your investments. For Singaporean investors, utilizing tax-advantaged accounts like the Supplementary Retirement Scheme (SRS) can provide significant tax savings. Investing your SRS funds in S&P 500 ETFs can help you grow your retirement savings more efficiently.

Keeping costs low

Minimizing investment costs is crucial for maximizing your returns. Pay attention to the expense ratios of the ETFs you choose, and opt for those with lower fees. Also, consider the trading fees charged by your brokerage and look for cost-effective options.
