Two research houses expect the Thai economy expanded by 3.5 per cent in the second quarter.
The Office of National Economic and Social Development Board is due to release the official figures today.
In the first quarter, the economy expanded 3.2 per cent from the same period last year. Both Maybank Kim Eng Securities (Thailand) and DBS Research anticipated an improvement in the second quarter, thanks mainly to public spending and tourism income while private sector demand continued its gradual recovery phase. Fiscal expenditure jumped 19 per cent on the year in the quarter, the strongest since 2013.
Maybank maintains the view that this year's growth will hit 4 per cent.
DBS expects a full-year growth rate of 3.4 per cent, citing that the economy could push 4 per cent only if private sector demand rises.
It said both private consumption and investment growth were likely to come in around 2.5 per cent this year. Without public sector support, gross domestic product growth would have been around 2.5 per cent.
Mr Apisak recently estimated the economy would grow at an annual rate of 3.4% in the second quarter, exceeding the first quarter's 3.2% rate that was also the fastest annual growth in three years.
