Singapore investors have more access than ever to the world's largest equity market. Whether you are looking to diversify beyond the SGX or gain exposure to global technology leaders, learning how to buy US stocks in Singapore is a practical first step. This guide covers everything from choosing a MAS-regulated broker to understanding custodian arrangements, fees, and tax considerations for Singapore residents.

Key Takeaways

• You need a brokerage account with US market access to buy US stocks from Singapore.

• Choose a broker holding a Capital Markets Services (CMS) Licence issued by the Monetary Authority of Singapore (MAS).

• US stocks are held in a custodian account, not the CDP (Central Depository).

• Currency conversion from SGD to USD is required before trading.

• Margin trading is available now.

• Past performance is not indicative of future results.

Part 1: Why Singapore Investors Buy US Stocks

1.1 Access to Global Market Leaders

The US stock market is anchored by two of its largest exchanges, the New York Stock Exchange (NYSE) and Nasdaq, while also encompassing other exchanges and trading venues. For Singapore investors, whose local SGX market is relatively concentrated in financials, real estate investment trusts (REITs), and industrials, US equities can provide exposure to sectors that are less represented locally, including technology, semiconductors, biotechnology, software-as-a-service (SaaS), and consumer discretionary.

Companies such as Apple (AAPL), Microsoft (MSFT), NVIDIA (NVDA), and Alphabet (GOOGL) are not listed on the SGX. Gaining direct ownership in these businesses requires access to a US-linked brokerage account. This is a key reason why cross-border investing, which are Singapore residents investing in US, HK, and China A-share markets, has grown substantially in recent years.

1.2 Portfolio Diversification for Singapore Residents

Geographical diversification is a foundational principle of portfolio construction. Concentrating investments solely in Singapore means your portfolio is exposed to the economic cycle of a single, relatively small open economy. Adding US equities introduces exposure to different economic drivers, interest rate environments, and corporate earnings cycles.

Investors should note that diversification does not eliminate investment risk, and the value of investments may rise or fall. When holding USD-denominated assets, investors should also consider currency risk arising from fluctuations in the SGD/USD exchange rate.

1.3 SGX vs US Market: Key Differences for Singapore Investors

Overseas-listed investment products are subject to a different regulatory regime and legal system than SGX-listed products. Singapore investors should be aware of this distinction before trading US-listed securities.

Part 2: Understanding Brokerage Accounts for US Stocks in Singapore

2.1 CDP Account vs Custodian Account

Before opening a brokerage account, it is important to understand how your assets will be held.

CDP Account (Central Depository Account): A direct securities account maintained by the Singapore Exchange's Central Depository (Pte) Limited. SGX-listed shares are registered directly in your name. The CDP account is used exclusively for SGX-listed securities.

Custodian Account: An account where your securities are held by the broker or a third-party custodian on your behalf. All US stocks purchased through Singapore-based online brokers are held in custodian accounts, not the CDP. Your beneficial ownership is recorded by the broker, and the securities are typically held in an omnibus account with a US clearing house.

When US shares are purchased through a Singapore-based broker, they are generally held through a custodian or nominee arrangement, as is common in international markets. Under Singapore’s Securities and Futures Act framework, MAS-regulated brokers are subject to requirements governing the segregation and safekeeping of client money and assets. These requirements are intended to keep client assets separate from the broker’s own property.

Singapore does not provide brokerage-account protection comparable in scope to the US Securities Investor Protection Corporation. Instead, client protection relies primarily on regulatory segregation requirements, custodial safeguards and certain limited statutory compensation arrangements.

2.2 What Is a CMS Licence?

A Capital Markets Services (CMS) Licence is issued by the Monetary Authority of Singapore under the Securities and Futures Act. It authorises a firm to conduct regulated activities such as dealing in capital markets products (including securities and futures). When selecting a broker to buy US stocks in Singapore, verifying that the firm holds a valid CMS Licence is a non-negotiable first step.

MAS maintains a public Financial Institutions Directory where you can verify any broker's licensing status.

Part 3: How to Buy US Stocks in Singapore — Step-by-Step Guide

Step 1: Choose a MAS-Licensed Broker with US Market Access

Select a broker that holds a valid CMS Licence and provides direct access to US exchanges (NYSE and Nasdaq). Key factors to evaluate include commission structure, platform fees, currency conversion costs, available order types, research tools, and the quality of the mobile application.

Step 2: Open and Fund Your Account

Most Singapore-focused online brokers offer fully digital account opening. Many integrate with Myinfo via Singpass, which automates identity verification using your NRIC data. Webull Singapore currently supports user registration via Singpass. You will typically need to:

• Complete a Know Your Customer (KYC) application

• Submit proof of identity (NRIC or passport)

• Complete a Customer Account Review (CAR) form as required under MAS regulations

Funding methods commonly available to Singapore residents include PayNow, FAST bank transfer, and direct debit arrangements (DDA). Funds are typically received in SGD. TT deposit for HKD & USD are also available

Step 3: Convert SGD to USD

US stocks are priced and settled in USD. You will need to convert your SGD to USD before placing a buy order. Be aware of the foreign exchange (FX) spread, which is the difference between the interbank rate and the rate offered by your broker. This is a real cost that affects your overall investment return. Some brokers offer multi-currency accounts that allow you to hold SGD, USD, HKD, and other currencies simultaneously.

Step 4: Research Your Target Stock or ETF

Before placing any order, conduct thorough research. Consider:

• The company's financial statements, revenue growth, and valuation metrics

• Sector and macroeconomic context

• For ETFs: the underlying index, expense ratio, and liquidity

• Your own risk tolerance and investment horizon

Step 5: Place Your Buy Order

Navigate to the stock or ETF on your broker's platform and select your order type:

• Market Order: Executes immediately at the prevailing market price. Suitable for highly liquid stocks where price slippage is minimal.

• Limit Order: Executes only at your specified price or better. Provides price control but does not guarantee execution.

• Stop-Limit Order: Combines a stop trigger with a limit price, useful for managing downside risk on existing positions.

Webull Singapore is a MAS-regulated online brokerage that offers Singapore investors access to US and Hong Kong-listed securities. The platform is designed for both newer investors and those with more trading experience, offering a range of order types, analytical tools, and market data features.

Regulatory Status

Webull Singapore holds a Capital Markets Services (CMS) Licence from the Monetary Authority of Singapore, authorising it to deal in capital markets products.

US Market Access and Trading Hours

Webull Singapore provides access to US-listed stocks and ETFs on the NYSE and Nasdaq. US regular trading hours run from 9:30 AM to 4:00 PM Eastern Time (ET). In Singapore Time (SGT), this corresponds approximately to 9:30 PM to 4:00 AM (during US winter/standard time) or 9:30 PM to 4:00 AM (adjusted during US summer/daylight saving time).

Webull also supports pre-market, after-hours trading and overnight trading for US stocks:

To access extended hours trading on the Webull app, place a limit order and select "Include Extended Hours" under Trading Hours. Note that extended hours trading carries additional risks, including lower liquidity and wider bid-ask spreads.

Fractional Shares on Webull

Webull offers fractional share trading for selected US stocks and ETFs. This feature allows Singapore investors to purchase a position in a high-priced stock with as little as USD 1, making it possible to build a diversified portfolio without needing to commit to the full price of a single share.

What is a Fractional Share? A fractional share represents ownership of less than one whole share of a company. For example, if a stock is priced at USD 500 per share, a fractional share allows you to invest USD 50 and own 0.1 of a share. Your gains, losses, and any dividends are proportional to your fractional ownership.

How to trade fractional shares on Webull:

1. Tap on the stock and check for the green diamond logo indicator at the top right of the page, this confirms the stock supports fractional trading.

2. Tap "Trade."

3. Tap "Order Type."

4. For a market order: select "Order Type: MARKET" and choose to trade by share amount or USD value.

5. For a limit order: select "Order Type: LIMIT" and enter a fractional share quantity to up to five decimal places (minimum: 0.00001 shares or USD 1).

6. Review and confirm your order.

Important notes on Webull fractional shares:

• Fractional shares are only available for selected US stocks and ETFs.

• Fractional share trading is only available during US regular trading hours (9:30 AM – 4:00 PM ET). It is not available during pre-market or after-hours sessions.

Part 5: Fees, Tax, and Risk Considerations for Singapore Investors

5.1 Fee Structure Overview

When buying US stocks from Singapore, the following cost categories apply:

Brokerage commission: The fee charged per trade. Some online brokers offer promotional or ongoing zero-commission structures for US stocks. However, investors should review the full fee schedule, as other charges may apply.

Platform and custody fees: Some brokers charge monthly or quarterly custody fees for holding US securities. Others do not. Verify the full fee schedule before opening an account.

Foreign exchange (FX) conversion costs: Converting SGD to USD incurs a spread. This is often the largest hidden cost for Singapore investors trading US stocks. A spread of even 0.5% on every deposit and withdrawal adds up meaningfully over time.

Regulatory and exchange fees: US trades may be subject to SEC transaction fees and FINRA Trading Activity Fees (TAF), which are typically small but should be factored into your cost calculation.

Rates vary by service provider; please refer to the latest pricing on the official website. For US stock commissions, fees are typically quoted in USD; for SGX stock commissions, fees are typically quoted in SGD.

The Bottom Line

Buying US stocks from Singapore is accessible through any MAS-licensed broker offering a custodian account with US market access. Webull Singapore provides a regulated platform with fractional shares, extended trading hours, and a range of order types suited to different investor needs. Compare fees carefully — including FX conversion costs — and ensure any investment aligns with your personal risk tolerance and financial goals. Past performance is not indicative of future results.
