If you're thinking about starting to trade a new stock, many people often overlook broker fees. But I can tell you that this is the critical point that determines actual profit. A commission fee as high as 0.05% can eat into your profits significantly if you trade frequently. So I decided to gather information about Thai brokers and their fee structures to clarify who you should choose.

From what I've compiled, in 2026, most broker fees are still around 0.15% for Cash Balance accounts and 0.20% for Cash Accounts. However, some brokers have taken different approaches, such as SBI Thai Online, which reduced fees to 0.075% and 0.10%, respectively, or Liberator, which offers zero commission fees. This is very attractive for those who trade at high frequency.

But lower fees don't necessarily mean the best. You also need to consider whether the broker has a minimum fee. Bualuang and Krungthai XSpring have no minimum fee, which is an advantage for traders with small trading volumes. Conversely, Kasikorn Thai and UOB have a minimum fee of 50 baht, and Philip has 30 baht, which could be a disadvantage if you trade infrequently.

In fact, choosing a broker should be a comprehensive decision. Not just based on fees, but also on whether the trading system is stable, the quality of customer service, and whether they offer good analytical tools. If you only focus on the lowest fee, you might regret it later when problems arise. I recommend opening accounts with 2-3 different brokers and choosing the one that best suits each trading occasion.
