I just noticed that broker fees are a very important variable when choosing a stock trading platform. I happened to look at the figures of various brokers in Thailand this year and want to share what I found.

Regarding fees, this is really important. If you buy only a few stocks but encounter a broker with a high minimum fee, your profit almost disappears. Conversely, if you find a broker with low commissions and no minimum, it helps reduce costs significantly.

Looking at the comparison table, I see that different brokers have various fee rates. Bualuang and InvestX charge 0.15% for Cash Balance accounts and 0.20% for Cash Accounts, but waive the minimum fee if using E-Confirmation.

The standout is SBI Thai Online, which charges much less—0.075% for Cash Balance with no minimum fee at all. If you buy stocks in small amounts like me, this broker is very suitable.

There’s also Liberator, which the documents say charges 0% commission for trading via the app, with no minimum fee. If this is true, it’s very interesting because you only pay the fees required to send to the stock exchange.

Other brokers like Kasikorn, Thanachart, Krungthai, XSpring, UOB, and Philip also have standard rates around 0.15-0.20%, but most have a minimum fee of 50 baht, with Philip’s being as low as 30 baht.

Where do these fees come from? Because brokers act as intermediaries, connecting investors with the stock exchange. They need to earn income, so they charge fees based on trading volume.

Another interesting point is the difference between Cash Balance and Cash Account. Cash Balance requires full transfer of funds before buying, with lower fees. Cash Account allows buying first and paying later, with higher fees, but it extends credit beyond your available funds.

For trading CFD stocks, which are derivative instruments, most do not charge trading fees. Instead, brokers earn from the bid-ask spread. If you’re interested in trading this way, you should choose a broker regulated by a reputable authority.

In summary, if you are an investor with a small capital and trade frequently, Liberator and SBI Thai Online are worthwhile because of low fees and no minimums. If you trade larger volumes, the fee differences aren’t that big. The key is to choose a broker with good service, stable systems, and good analytical tools.
