I’ve been looking for a stock broker with no minimum commission for a long time, because when you buy only a small number of shares, it’s a shame to have to pay a minimum fee of 50–100 baht—so the cost is very high. That’s why I wanted to find a broker that charges only based on how much you buy, with no minimum commission fee.

In the end, I found several options. Especially this year, 2569 (2026), many brokers have adjusted their fee rates to look more attractive. In particular, brokers that focus on small investors—Bualuang, Innovest X, and SBI Thai Online—are good choices. If you open a Cash Balance account, there are no minimum fees. You pay according to your actual trades, nothing more.

But if we’re talking about the lowest rate, SBI Thai Online wins, because they charge only 0.075% for Cash Balance accounts, with no minimum commission fee. Rates like this are hard to find, and Liberator is also interesting. They call it “0% commission,” meaning there is no broker fee at all—only the various charges that the Stock Exchange requires.

For other stock brokers, such as Kasikorn, Thanachart, and Tisco, the standard rates are around 0.15–0.20%, but most also have a minimum fee of 30–50 baht. If you buy small amounts, it won’t be cost-effective.

So to sum it up: if you want to trade stocks with small amounts and no minimum, open a Cash Balance account with Bualuang, Innovest X, or SBI Thai Online. Liberator is the cheapest, but you should also review their programs and services. In 2569 (2026), there are really more options for stock brokers with no minimum fees.
