There is no single best online broker in Singapore for 2026: Moomoo, Webull and Syfe Trade list US$0 commission on US stocks, Interactive Brokers (IBKR) is built for bigger trades and global markets, and Tiger Brokers has the highest published rate card of the five on the schedule I could verify.

I compared Tiger Brokers, moomoo, IBKR, Webull and Syfe Trade on US stock fees, SGX fees, account minimums and markets covered, using each broker's own pricing page and Singapore comparison sites, as of 12 October 2026.

The headline "zero commission" claims are mostly true. The fine print is where the brokers differ: platform fees, promo periods that end, and which accounts the lowest rates apply to.

Here is the quick version before the detail. Figures are headline rates, before 9% GST and exchange pass-through fees.

In plain terms, four of the five list US$0 commission on US stocks, so commission is no longer the real comparison.

The real comparison is everything around it. And one row, Tiger, is not like the others on its published schedule, which I would rather flag now than bury.

Rate cards are hard to compare, so I ran the same trade through each one. Both examples are before 9% GST and exchange or regulatory pass-through fees.

Example 1: buy 100 shares of a US stock at US$20 (US$2,000 trade)

Example 2: buy S$2,000 of an SGX stock

Here is the honest crux. On a small trade, minimum fees matter far more than percentage rates. A S$2,000 trade is where Tiger's S$4.99 and S$5 minimums bite hardest, and where Syfe's S$1.98 minimum looks very different. MoneySmart lists Tiger at a lower headline figure (US$0.99 per US order, asterisked), so Tiger's real cost depends on which account plan you are on.

Tiger Brokers. Its Cash Boost schedule charges 0.10% commission plus a 0.12% platform fee on US, Hong Kong and Singapore stocks, each with a minimum. That is the highest published cost of the five for small trades. Tiger may still suit you if you already hold an account or a promo applies, but on the numbers I could verify I would not pick it on fees alone.

Moomoo. Its pricing page lists US$0 commission on US stocks and ETFs (described as lifetime), free LV2 US market data, and S$0 SGX commission for one year for new users. The catches are the platform fee on US orders and what SGX costs after year one. For the closest alternative on fees, see my uSMART review.

Interactive Brokers. IBKR's Singapore commission page shows IBKR Lite at US$0 commission on US stocks for eligible retail investors, and IBKR Pro at US$0.005 per share (min US$1, max 1% of trade value) on fixed pricing, or US$0.0005 to US$0.0035 per share on tiered pricing with a US$0.35 minimum. There is no account minimum or maintenance fee. It suits people who trade bigger size or want global markets, and the platform has a steeper learning curve.

Webull. MoneySmart lists US$0 commission and 0% platform fees on US stocks, plus fractional shares from US$5. The thing I would check is the account minimum, because the page conflicts with itself (no minimum in one place, S$2,000 in its FAQ). The welcome promotion on that page runs only until 13 October 2026, so treat the zero-fee headline as promo-dependent.

Syfe Trade. Per Syfe's own comparison, US stocks and ETFs carry no commission or platform fee, SGX is 0.04% to 0.06% with a S$1.98 minimum, and you can buy fractional US shares from US$1, trade eligible US names 24/5 and access UK-listed UCITS ETFs. Of the five, it has the cleanest published fee card for a small SGX trade.

If you want the tools side of this decision, not just fees, my free guide Your Ultimate Guide to Investing Tools covers several of these brokers in more depth.

Popsmith is reimagining popcorn for a new generation. With 100,000+ customers, $20M+ in lifetime revenue, and sales projected to reach $9M in 2026, the premium popcorn brand is expanding nationwide and raising capital for its next stage of growth.

This is my personal read, not a ranking, and nothing here is a recommendation for your situation.

What I would watch next: whether the zero-commission promos survive once the sign-up wave passes, and whether more brokers publish a clear SGX rate card.

On commission alone, Moomoo, Webull, Syfe Trade and IBKR Lite list US$0. The difference is platform fees, promos and what happens on larger or more frequent trades, so compare the total cost on your typical order size.

On the figures I verified, Syfe Trade has a clear published rate of 0.04% to 0.06% with a S$1.98 minimum, and Moomoo offers S$0 SGX commission for one year to new users. I could not verify IBKR's SGX rate, so check its schedule.

I could not confirm CPF or SRS funding for any of the five from the pages I checked. Do not assume either way. Check directly with the broker and the CPF or SRS approved lists before you plan around it.

Moomoo's pricing page lists US$0 commission on US stocks and ETFs, but other fees such as the platform fee and GST can still apply. In my Moomoo review, the US platform fee was US$0.99 per order.

There is no account minimum or maintenance fee, and Lite lists US$0 US commission for eligible retail investors. Whether it is worth it depends on how comfortable you are with a more complex platform.

Syfe and IBKR list no minimum, Moomoo lists S$0, and MoneySmart lists S$1 for Tiger. Webull's page conflicts: no minimum in one place and S$2,000 in its FAQ. Confirm in the app.

Moomoo's and Tiger's pages both state 9% GST applies to fees such as commissions and platform fees. Check how GST applies to your own account.

I did not verify each licence for this article. Check each firm on the MAS Financial Institutions Directory before you deposit.

Syfe lists 24/5 trading for eligible US stocks and ETFs. I did not verify extended-hours access for the other four, so check each platform.

Often. Promos in particular run for fixed periods, so treat any comparison, including this one, as a snapshot and check the live fee schedule before you open an account.

What this comparison gives you is permission to stop worrying about US commission. Four of the five list US$0, and the real choice is about platform fees, SGX pricing and how you like to trade.

The open question is how many of those zeros are promotional. Several carry asterisks, and I could not verify IBKR's SGX rate or every platform fee. I would treat the lowest published numbers as the best case, not the guarantee.

What I would do next: pick the one or two that match your habit, read the live fee schedule on the day, and run your own typical trade through it like I did above. For a fuller rundown of where each tool fits, grab Your Ultimate Guide to Investing Tools.
