Just researched the brokerage fees for Thai stocks in 2026, and found that this issue is more important than I thought because the commission fees really eat into profits. Choosing the right stockbroker makes a big difference.

From what I’ve seen, there are 2-3 providers with the lowest commissions, such as SBI, which charges only 0.075% for Cash Balance accounts with no minimum fee, making it very suitable for small-volume investors. Then there’s Liberator, known for its “0% commission” feature—if you trade through the app, there’s no minimum fee at all, so investors only pay the fee to the stock exchange.

For those who buy large volumes, Bualuang and Krungthai X Spring are also good options—they have no minimum fee, so you pay only for what you buy. Other brokers usually have a minimum fee of 30-50 baht, which doesn’t matter much when buying large amounts, but can be a problem for small trades.

The key is to consider how much you trade per transaction. If you buy small amounts, you should choose a broker with no minimum fee. If you trade large volumes, just look at the percentage rate. Personally, I think SBI and Liberator are the most cost-effective options. However, you also need to check whether each broker offers good analytical tools and a user-friendly UI/UX, because sometimes a low commission isn’t worth it if the system isn’t good.
