A group representing the Thailand Consumers Council express opposition to the merger deal at the office of the NBTC on Thurday. Mr Somkiat said the Herfindahl-Hirschman Index (HHI) is commonly used to gauge market concentration conditions. A total of 1,500 points suggests a risk of market concentration, while above 2,500 indicates market concentration is at a dangerous level. Based on research in 2017 by Ofcom, the UK's telecommunications regulator, Thailand's mobile market already had a high level of market concentration at 3,700 points, he said. Prawit Leesathapornwongsa, an advisor to the NBTC chairman, said the NBTC has no bias in mind when considering the merger deal.
