This year, let’s look at how much stock trading commission each broker really charges, because this stock trading commission is truly a big factor that affects our profits. If the commission is too expensive, our profits will decrease accordingly.

How should you choose a broker? You have to look at the stock trading commission. Each broker has different rates—some are 0.15%, some are 0.20%, and some are even lower. There is also a minimum commission fee. Some brokers charge a minimum of 50 baht, some charge 30 baht, and some charge none at all. This is especially important if we trade stocks in small amounts.

From what I’ve seen, Liberator is the real deal when it comes to stock trading commission, because they do not charge any commission fees at all. Investors only pay the fee that the Stock Exchange of Thailand charges. SBI Thai Online is also a good option compared with other brokers: the stock trading commission is only 0.075% for cash balance accounts, and there is no minimum commission fee.

As for these bank-affiliated brokers—such as Bualuang, Krungthai, XSpring, and Thanachart—they use standard stock trading commission rates of 0.15% and 0.20%, depending on the account type. Bualuang and Krungthai XSpring are two brokers that have no minimum commission fee when certain conditions are met, which suits people who trade stocks in small amounts.

Kasikorn, Thanachart, and UOB have a minimum commission fee of 50 baht, while Phillips charges lower than that at 30 baht. If you think stock trading commission is important, check whether a cash balance account is cheaper than a cash account, because the commission difference is 0.05%. It may seem small, but if you trade in large amounts, it adds up over time.

In summary, stock trading commission comes from the fact that brokers act as intermediaries for buying and selling, receiving orders from us and sending them to the Stock Exchange of Thailand. This commission is their income. Some brokers use low-commission strategies to attract customers, while others focus on services and analytical tools. If you’re going to choose, you should weigh the stock trading commission against the services you get as well.
