Just tried collecting data on Thai broker fees for 2026.9. This is really important because it eats into profits. Many people think that just buying good stocks will yield profits, but they don't consider how high commissions cut into their gains.

From what I see, Liberator Securities emphasizes 0% commission for trading via their app, with no minimum daily fee. This is the most economical if you're buying small amounts of stock. Meanwhile, SBI Thai Online also offers a good deal—0.075% for Cash Balance accounts, which is much lower than the market average.

For those who prefer big banks, Bualuang, Krungthai, Kasikorn, and Thanachart are options. Most charge 0.15% for Cash Balance and 0.20% for Cash Account, with minimum fees of 50-100 baht. Some providers have no minimum fee at all.

I noticed that broker fees vary depending on the account type. Cash Balance accounts are cheaper than Cash Accounts because you need to deposit the full amount. Cash Accounts allow borrowing like a credit card, so they charge higher fees.

If you trade infrequently, Liberator or SBI Thai are interesting options. But if you want comprehensive services, Bualuang or Krungthai are good choices. The key is to select based on your trading habits because these fees are the main factor that can improve your profits.
