I just noticed that stock broker fees vary a lot between different providers. Choosing the wrong one could lead to paying commissions continuously.

Let's look at the stock broker fee data for 2026 that many providers offer. Some brokers charge a minimum commission per day, which means if you buy only a small amount of stock, the fee will always be rounded up. For example, SBI Thai Online charges only 0.075% for Cash Balance accounts, which is considered the cheapest in the market, while Bualuang, Krungthai XSpring, and many others charge 0.15% for the same type of account.

An interesting point is that Liberator still claims a 0% commission for trading via the app, with no minimum fee, making it the most cost-effective option for retail investors. Other brokers like Kasikorn, Thanachart, and UOB all charge a minimum fee of 50 baht.

If you're buying large quantities of stock, a percentage-based fee might not be an issue. But for small investors, choosing a broker with no minimum fee or the lowest possible fee can significantly increase net profits.
