Recently, I decided to spend time gathering information on stock trading fees from various brokers available in the Thai market in 2026. Because for people who buy stocks in small amounts, fees can really be a problem. Choosing the wrong broker might cost more in fees than the profit gained.

The issue of broker fees isn't as simple as it seems. Each broker has different calculation methods. Some have no minimum fee, some do. Some are cheaper, some are more expensive. After reviewing the data, I found that Bualuang and SCBS (Siam Commercial Bank Securities) waive the minimum fee when using E-Confirmation, which is good for small investors. SBITO (Siam Commercial Bank Online Securities) is much cheaper, about 0.075% for cash balance accounts. And Liberator is the most aggressive because it charges no fees at all.

When comparing general stock trading fees, most brokers charge 0.15% for cash balance accounts and 0.20% for cash accounts. But the difference comes from the minimum fee per day—some charge 50 baht, some 30 baht, and some have no minimum. For small stock purchases, this minimum fee is a big problem because it makes the effective fee rate look like buying in large quantities.

Kasikorn and TMB (Thanachart Securities) have a minimum fee of 50 baht, while Philip Securities charges 30 baht. Interestingly, Krungthai XSpring has no minimum fee at all. So, if buying small amounts of stocks, this broker is a good choice when comparing fees.

For those who want to profit from price differences without holding actual stocks, there are alternatives like CFDs. But be careful because they are high risk. Most CFDs have no trading fees, but brokers earn from the spread. If choosing, you should pick a broker that is trustworthy and regulated by a proper authority.

In summary, for small-volume stock trading, Liberator is definitely the cheapest. But if you want additional services, Krungthai XSpring and SBITO are good options. For those buying large quantities, the fee differences may not be significant. The most important thing is to choose a broker with good service, reliable analysis systems, and trustworthiness.
