The Stock Exchange of Thailand topped the region last year in terms of raising funds, with US$7.5 billion mobilised by listed companies.
The strong performance was on the back of a strong economy, huge fund inflows, low rates and bright prospects related to Asean integration in 2016.
Chanitr Charnchainarong, the SET's executive vice-president, said listed companies on the SET and Market for Alternative Investment (MAI) raised $7.5 billion, followed by Malaysia at $2.8 billion and Singapore at $2.1 billion.
He said Thai firms returned to expansion mode after projects had been frozen since 2008 when the US sub-prime crisis hit, followed by domestic political strife and floods in late 2011.
"This is a good time to raise funds from the market. Normally, when a company raises capital, its share price will decline on the dilution effect, but because of the supporting factors, their stocks performed well," said Mr Chanitr.
The big fund-raisers last year were Krung Thai Bank and PTT Group.
This year, fund-raising demand will continue from small and mid-sized firms, but less so than last year.
Many companies on both the SET and MAI plan to seek approval from shareholders in April to raise capital and issue bonds.
Mr Chanitr said listed firms are healthy because dividends have not been harmed by the increasing number of shares.
