"Players have adopted a wait-and-see stance. They are waiting to see what will happen to the rice intervention scheme and the domestic price after the general election" on Sunday, said one broker.
The government's rice buying scheme, designed to boost domestic prices, has been extended for another month to March 31.
Brokers said the futures prices were expected to be trapped in narrow range of 10.46-10.56 baht per kg over the next few days, tracking the physical market.
On the physical front, Thai 5 percent white rice was quoted unchanged at 10.50-10.55 baht on Wednesday.
