Which broker should you choose? In this case, you need to look carefully at the fees, because they take a big bite out of your profits. The commission charged by each provider differs a lot—some have no minimum, while others have a minimum of 50 baht or 30 baht. That’s what ultimately determines whether you make a profit or lose.

Let’s take a quick look at which broker has the lowest fees in 2569 (2026). Liberator is still cutting commissions at 0%—no matter how much you buy, there’s no commission fee from the broker. You only pay the fee charged by the stock exchange. If you want to save the most, this one is the best.

SBI Thai Online is also good. The commission is only 0.075% for a cash balance account, with no minimum. If you trade small amounts, it’s cost-effective. But if you use a cash account, it increases to 0.10% with a minimum of 50 baht.

Bualuang and Krungthai XSpring have standard rates of 0.15% and 0.20%, depending on the account type. However, Bualuang has no minimum if you use E-Confirmation, and Krungthai XSpring also has no minimum.

InnoVest X (หลักทรัพย์ไทยพาณิชย์) is also 0.15% and 0.20%, but it has a minimum of 50 baht—except when you request an E-Statement, in which case there is no minimum.

Kasikornbank and Thanachart are very similar. Both charge 0.15% and 0.20%, with a minimum of 50 baht. Phillip’s is slightly lower: the minimum is only 30 baht, but the rates are the same—0.15% and 0.20%.

To sum up: if you buy stocks in small quantities or with low amounts of money, Liberator wins hands down. If you want a balance between commission fees and service, SBI Thai Online is worth trying. Bualuang and Krungthai XSpring are good options if you’re already an existing customer. But in the end, you need to check how much you trade per day to choose the right one.
