Since the May 2014 coup, a total of 6.4 million tonnes of rice have been sold via 15 auctions, fetching 66.6 billion baht. Government-to-government rice deals have unloaded 3.8 million tonnes worth 50 billion baht.
The government estimates there are less than 10 million tonnes in state stocks.
Mrs Duangporn said the government was likely to call the next rice auction for 1-2 million tonnes next month, noting sentiment remains bullish.
