Quick Answer: IBKR vs moomoo Singapore

The short answer depends on what you’re buying. For Singapore stocks (SGX) and London Stock Exchange ETFs like CSPX or VWRA, IBKR is substantially cheaper. Its 0.08% commission with a SGD 2.50 minimum consistently undercuts moomoo’s post-promotional rate of 0.22% (including platform fees and GST). On a SGD 30,000 ETF purchase, that difference translates to approximately SGD 44 per trade — real money for any serious long-term investor.

For US stocks, moomoo wins. Its lifetime zero-commission offer (with only a USD 0.99 flat platform fee per order) beats IBKR’s USD 0.005 per share minimum USD 1.00 structure at most trade sizes. If your strategy is dollar-cost averaging into S&P 500 US-listed ETFs or individual US stocks, moomoo saves you money on every single trade.

Both brokers are MAS-regulated with strong investor protections. The choice isn’t about safety — it’s about matching the broker’s fee structure to your investment style. We’ll break down every scenario below.

One note on moomoo’s current promotions: moomoo regularly runs zero-commission periods for SGX stocks and HK stocks. If you’re an active trader who can time your trades during promotions, moomoo can be competitive even for SGX. But for long-term buy-and-hold investors not timing promotions, the numbers favour IBKR for Singapore market exposure.

SGX Stock & ETF Fee Comparison

This is where the two brokers diverge most significantly. IBKR’s SGX pricing is straightforward: a flat 0.08% commission per trade with a minimum of SGD 2.50. You then pay standard SGX exchange fees (clearing fee: 0.0325%, trading access fee: 0.0075%) on top — these apply to every SGX broker, not just IBKR.

moomoo charges two separate fees: a 0.10% commission (min SGD 4.99) plus a 0.12% platform fee (min SGD 4.99). The same SGX exchange fees apply. Additionally, moomoo charges 9% GST on the commission and platform fee portions. This adds up quickly.

Here’s a worked example for a Singapore investor using their Singapore retirement calculator and building a long-term ETF portfolio on SGX:

Source: interactivebrokers.com.sg (0.08% min SGD 2.50) and moomoo.com/sg (0.10%+0.12% platform post-promo, 9% GST, SGX clearing 0.0325%, trading fee 0.0075%). September 2026 verified rates. IBKR costs include SGX exchange fees.

Important note on IBKR’s inactivity fee: If your monthly commissions at IBKR total less than USD 10 (approximately SGD 13.50), IBKR charges the difference as a maintenance fee. For Singapore investors who make 2–3 SGX trades per month of SGD 10,000+, this threshold is easily met (SGD 12 commission per trade × 2 = SGD 24 commission). For investors trading less frequently, factor in up to USD 10/month (SGD ~13.50) in additional costs when comparing.

The bottom line: IBKR’s total cost of ownership for SGX stocks is significantly lower, especially for investors who make at least 2–3 trades per month. This is why most experienced Singapore investors, including those building passive income portfolios with the best S-REITs in Singapore 2026, prefer IBKR for Singapore market exposure.

US Stock & ETF Fee Comparison

For US-listed stocks and ETFs, the dynamics flip entirely in moomoo’s favour. moomoo offers lifetime zero commission on US stocks and ETFs, with only a USD 0.99 platform fee per order. This is a significant structural advantage for investors focused on US market exposure.

IBKR Pro (Fixed Rate) charges USD 0.005 per share with a minimum of USD 1.00. At low share counts (50 shares or fewer per trade), IBKR and moomoo are cost-equivalent at roughly USD 1.00 per order. But as share count rises, IBKR’s per-share model becomes increasingly expensive relative to moomoo’s flat USD 0.99:

For Singapore investors using SRS funds to invest in US-listed ETFs, moomoo’s zero-commission structure offers meaningful compounding advantages over time. On a strategy of monthly USD 500 contributions into S&P 500 ETFs, switching from IBKR to moomoo saves approximately USD 11.88 per year in commissions — small individually, but compounded over 20 years at 7% annual returns, that’s over USD 560 in foregone investment capital.

IBKR Tiered pricing (starting at USD 0.0035/share, min USD 0.35) may be more competitive than Pro Fixed for very high-frequency traders — but for retail investors making a few trades per month, the comparison above using Fixed pricing is more representative.

Regulation & Safety: Are Both Brokers Safe?

Both IBKR and moomoo hold Capital Markets Services (CMS) licences from the Monetary Authority of Singapore (MAS). Under MAS regulations, both brokers are required to segregate client assets from company assets — meaning your stocks and cash are held separately from the broker’s own funds and are protected if the broker faces financial difficulties.

Interactive Brokers Singapore: IBKR’s global parent (Interactive Brokers LLC) has been publicly traded on NASDAQ since 2007 and holds over USD 14 billion in equity capital as at 2026. It is one of the most heavily regulated brokers globally, operating under oversight from the SEC, FINRA, FCA (UK), and MAS. Its Singapore entity holds a CMS licence for dealing in capital markets products.

moomoo / Futu Singapore: moomoo is operated by Futu Singapore Pte. Ltd., a wholly owned subsidiary of Futu Holdings Ltd (NASDAQ: FUTU). Futu Holdings is listed on NASDAQ and headquartered in Hong Kong. Futu Singapore holds a MAS CMS licence (Dealing in Capital Markets Products). As a NASDAQ-listed entity, Futu Holdings is subject to SEC reporting requirements, providing an additional layer of transparency for investors.

Both brokers comply with MAS’ Securities and Futures Act and maintain client asset segregation as required by MAS. Neither is covered by Singapore’s Deposit Insurance Scheme (which covers bank deposits, not securities), but both maintain client asset segregation as required by MAS. For investors concerned about counterparty risk, IBKR’s larger balance sheet and longer operating history (founded 1978 vs Futu founded 2012) may offer additional comfort.

For Singapore investors also weighing robo-advisors as alternatives, platforms like Syfe referral code offer a different risk and cost profile — worth comparing if you want a more hands-off approach to building a diversified portfolio.

Platform Features & Tools

The fee comparison tells only part of the story. The two platforms are built for different users.

IBKR’s Trader Workstation (TWS) is a professional-grade desktop platform with advanced charting, options chains, futures, and algorithmic trading capabilities. IBKR also provides access to 150+ markets globally — including the London Stock Exchange, where Singapore investors typically buy UCITS ETFs like CSPX and VWRA to avoid US estate tax exposure. For investors building a globally diversified ETF portfolio, IBKR’s breadth is unmatched. The platform’s learning curve is steeper than moomoo’s, but IBKR offers detailed educational resources and a paper trading mode. Additionally, IBKR provides competitive margin rates — typically 4.08% USD (as at Q3 2026) — for investors who use leverage.

moomoo’s mobile app is widely regarded as one of the most polished trading apps in Singapore, with a Bloomberg Terminal-style interface that includes real-time Level 2 market data, 24/7 US market data, financial calendars, analyst ratings, and a social trading community where investors share ideas. The paper trading feature is particularly accessible — new investors can simulate trades without risking real money. moomoo also provides free earnings calendars, dividend tracking, and AI-powered stock screeners. For someone learning to invest, moomoo’s environment is substantially more welcoming.

Who Should Use Which Broker?

Choose IBKR if you:

• Invest primarily in SGX stocks, REITs, or ETFs listed on the Singapore Exchange
• Buy UCITS ETFs on the London Stock Exchange (CSPX, VWRA, SPYL, VUAA) — IBKR’s LSE access and low commission rates make it ideal for tax-efficient global ETF investing
• Have a portfolio above SGD 50,000 and make regular trades — the lower fee percentage adds up significantly
• Want access to 150+ global markets, including European and Asian exchanges beyond Singapore and Hong Kong
• Trade actively enough to avoid the USD 10/month inactivity fee (i.e. you generate ≥ USD 10 in commissions per month)
• Need professional tools — margin, futures, algorithmic trading, or options at scale

Choose moomoo if you:

• Focus primarily on US stocks or US-listed ETFs (S&P 500, QQQ, sector ETFs) — zero commission is a genuine long-term advantage
• Are a beginner investor who wants a polished, educational app with paper trading and community features
• Have a smaller portfolio and don’t want to worry about monthly activity minimums
• Want free Level 2 market data without paying extra
• Invest during moomoo’s promotional SGX commission-free periods
• Want HK IPO access through the Futu platform

Verdict for LSE ETF investors: If your primary strategy is buying Ireland-domiciled ETFs on the London Stock Exchange to avoid US estate tax and benefit from the 15% withholding tax treaty, then IBKR is the better platform. IBKR has direct access to the LSE with competitive commission rates, while moomoo does not offer LSE-listed ETF access at all. This is also why most passive income Singapore strategies for dividend ETF investors recommend IBKR for Singapore Exchange REITs and London-listed global ETFs.

Can you use both? Yes, and many Singapore investors do. A common strategy is to use IBKR for LSE ETFs and SGX REITs, and moomoo for US equity exposure or stock-picking. Both accounts can be opened and maintained simultaneously with no conflict.
