“Just S&P and chill” has become a familiar investment mantra, particularly among younger investors. The S&P 500 tracks 500 leading US companies, offering a straightforward way to gain exposure to US equities. Singapore investors can access it through several exchange-traded funds (ETFs), with new Irish-domiciled Xtrackers ETFs scheduled to begin trading on the Singapore Exchange (SGX) on 13 October 2026.
However, choosing an ETF involves more than comparing its total expense ratio (TER), which measures its annual fund expenses. Where the fund is domiciled, how it handles dividends and the currency it trades in also affect costs and tax treatment. Here are five options to consider, and the trade-offs that matter for Singapore investors.
Xtrackers S&P 500 UCITS ETF (SGX: XUS)
XUS is a cross-listing of an existing Irish-domiciled Xtrackers fund managed by DWS. It is scheduled to begin trading on SGX on 13 October 2026, with an indicative listing price of around S$20 per share. Its TER is 0.03% a year, equivalent to approximately S$3 in annual fund expenses for every S$10,000 invested.
The fund trades in Singapore dollars, so investors funding their purchases in SGD do not need to make a separate currency conversion. They can also trade during Singapore market hours through a brokerage that supports the counter. This makes access more convenient, although brokerage charges and the difference between buying and selling prices, known as the bid-ask spread, still affect the overall cost.
Its Irish domicile generally allows US dividends received by the fund to be taxed at 15%, rather than the 30% typically applicable to distributions from US-domiciled ETFs held by Singapore investors. XUS accumulates dividends, meaning it reinvests them rather than paying them out. Investors therefore do not need to reinvest cash distributions themselves, but accumulation does not eliminate dividend withholding tax.
For Singapore investors who are not US persons, holding shares in an Irish-domiciled ETF generally avoids the US estate tax exposure associated with directly holding US-domiciled ETFs. As XUS is a new SGX listing, investors should check its actual bid-ask spread and trading conditions before assuming it is the cheapest option overall.

SPDR S&P 500 ETF Trust (SGX: S27)
S27 has been listed on SGX since 2001 and is a cross-listing of SPY, the original US-listed S&P 500 ETF. Although investors buy it on a Singapore exchange, the fund is domiciled in the US. Its listing location does not change its tax treatment.
S27 trades in US dollars, so investors need a USD balance or must convert their Singapore dollars. Its expense ratio of 0.0945% is the highest among the five funds covered here. It distributes dividends quarterly, with distributions generally subject to 30% US withholding tax for Singapore investors who are not entitled to a lower treaty rate.
Compared with the 15% fund-level withholding rate generally available to Irish-domiciled ETFs, this leaves less dividend income available for spending or reinvestment. The difference applies to dividends, rather than the value of the entire investment, but can still affect returns over a long holding period.
US estate tax is another consideration. For non-US citizens who are not US-domiciled, US-situated assets can create estate tax exposure. An estate tax return is generally required when these assets, together with certain relevant gifts, exceed US$60,000 at death. This threshold applies across the investor’s relevant US assets, rather than separately to each ETF.
S27 offers a long track record and access through SGX. However, its higher fund expenses and tax treatment can make it less cost-efficient for long-term Singapore investors than the Irish-domiciled alternatives. Investors should compare live trading spreads rather than assume that an established listing guarantees a lower trading cost.
SPDR Portfolio S&P 500 UCITS ETF (LSE: SPYL)
SPYL is an Irish-domiciled, accumulating S&P 500 ETF available on the London Stock Exchange (LSE). Its TER is 0.03%, matching XUS, and it offers the same broad dividend withholding tax and US estate tax advantages associated with an Irish-domiciled structure.
The LSE counter trades in USD, so investors funding purchases in SGD need to consider currency conversion costs. They also need a brokerage with access to the counter, such as Interactive Brokers or FSMOne, and must trade during London market hours.
For investors making regular monthly contributions, brokerage and currency conversion charges can add up. However, this does not automatically make SPYL more expensive than XUS. The comparison depends on the broker’s fees, purchase size and each counter’s bid-ask spread. SPYL remains an option for investors who already use an LSE-enabled brokerage and can transact at a low cost.
iShares Core S&P 500 UCITS ETF (LSE: CSPX)
CSPX is another established Irish-domiciled, accumulating ETF tracking the S&P 500. It trades in USD on the LSE and has a TER of 0.07%, with the same broad tax considerations as SPYL.
Both funds provide similar underlying market exposure, but their expenses and share prices differ. CSPX has a higher price per share, which may make smaller regular purchases less convenient where fractional shares are unavailable. A higher share price does not mean the underlying investment is more expensive in valuation terms.
The 0.04-percentage-point TER difference between CSPX and SPYL amounts to approximately S$40 a year on a S$100,000 investment. That is worth considering, but investors should also compare brokerage charges, currency conversion costs and trading spreads. Existing CSPX investors should weigh any savings against the cost of selling and switching funds.

Vanguard S&P 500 ETF (NYSE: VOO)
VOO is a large, established US-domiciled S&P 500 ETF with an expense ratio of 0.03%. It is accessible through brokerages that support its US listing and distributes dividends quarterly.
Its low fund expenses are attractive, but its US domicile creates the same broad tax considerations as S27. Dividend distributions are generally subject to 30% US withholding tax for Singapore investors without treaty relief, and holdings can contribute to US estate tax exposure.
VOO trades in USD during US market hours, which fall in the evening or overnight in Singapore. Investors funding purchases in SGD also need to account for currency conversion costs. While VOO offers straightforward access through many brokerages, its low expense ratio alone does not make it the lowest-cost choice after taxes and transaction charges.
Which Option Makes Most Sense For Singapore Residents?
XUS combines a 0.03% TER, SGD trading and an Irish-domiciled, accumulating structure. This makes it worth considering for investors who prefer to invest through SGX, provided their brokerage charges and the counter’s trading spread are competitive. SPYL and CSPX remain alternatives for investors with cost-effective access to the LSE, especially those who already hold these funds.
S27 and VOO generally have less favourable dividend tax treatment and potential US estate tax exposure for Singapore investors who are not US persons. These factors matter alongside fund expenses, rather than being outweighed automatically by a familiar ticker or convenient brokerage access.
Finally, buying an S&P 500 ETF in SGD does not remove exposure to movements between the US dollar and Singapore dollar. The underlying investment remains in US equities. Choose the fund based on its total cost, tax treatment and suitability for your investing routine, rather than its trading currency or headline fee alone.
