I just noticed the stock broker fees again and found that they significantly affect our profits. If the commission is high, the profit decreases accordingly. Conversely, if the commission is low, the profit increases. So I want to share what the commission rates of Thai stock brokers are like in 2026.

I observe that choosing a broker depends on how much we trade. Some charge a minimum commission per day, so if we buy stocks infrequently, we end up paying high commissions unnecessarily. Bualuang and Innovest X are good options if we want to avoid minimum commissions. The rate is 0.15% for Cash Balance accounts and 0.20% for Cash Accounts, with no minimum.

But if we want to find the lowest rate, SBI Thai Online is the real deal. The rate is 0.075% for Cash Balance and 0.10% for Cash Accounts, which is much lower than the market average. Liberator is also an interesting option if we trade through an app; they have no commissions at all.

Kasikornbank, Thanachart, Tisco, and Krungthai XSpring also charge standard rates of 0.15% and 0.20%. Some have a minimum commission of 50 baht, while others do not. UOB Kay Hian and Philip Securities are similar, but Philip has a minimum commission of only 30 baht. If you ask me, for small-volume traders, Liberator or SBI Thai Online are the most cost-effective choices.

Where do these broker fees come from? Since we only trade through the official stock exchange, brokers need to earn income. They do this by charging commissions on our trades. Each broker has different strategies: some have low rates but with minimum fees, others have higher rates but no minimum. Check which one best suits your trading style.
