Many people ask which broker actually offers the lowest commissions with no minimum, because fees are the ones eating into our profits by several percentage points, so they want to compare them directly.

Based on data from 2026, there are several brokers competing to lower their commissions; some offer around 0.15% for Cash Balance accounts, which is quite comfortable. But what's really interesting is that some brokers still have a minimum fee of 50 baht, so if you buy a small amount of stock, the commission can take up a large proportion.

My eye is on SBI Thai Online (SBITO), which charges only 0.075% for Cash Balance accounts with no minimum fee at all. If you buy only 5,000 baht worth of stock, you pay just 3-4 baht in commission—no rounding up to tens.

Liberator is also interesting, claiming a 0% commission. If that's true, it would be the most cost-effective, but you should check the details carefully to be sure.

For large brokers like Bualueng, Kasikorn, and Thanachart, most charge around 0.15-0.20%, but with a minimum of 50 baht. So if you trade in small amounts, it might not be cost-effective.

The key is to choose a broker that suits your trading volume. If you buy small amounts, look for one with no minimum. If you trade large volumes, you might opt for a broker with a lower rate even if there is a minimum, because the commission cost becomes less significant.
