SET-listed companies planning to raise funds through an initial coin offering (ICO) need to inform the bourse about such deals before embarking on fundraising.
Companies opting to raise funds through an ICO are required to inform the public through the SET's electronic disclosure platform, said Santi Kiranand, SET senior executive vice-president.
ICO fundraising could affect the share price of listed firms' equities, making information disclosure on such initiatives essential, said Mr Santi.
Earlier, Praoporn Senanarong, assistant secretary-general at the Securities and Exchange Commission (SEC), said ICOs could replace IPOs in the long run, disrupting the traditional operations of asset management firms, investment banking, investment advisories, exchanges and brokers.
ICOs provide an avenue for companies to raise funds quickly, unencumbered by the hefty regulations and waiting periods of a traditional IPO.
But ICOs have high investment because no regulatory framework is in place to supervise ICO deals, making investors vulnerable to fraud.
Financial regulators have been discussing the ICO regulatory framework, which is expected to be concluded by next month.
Public hearings on the ICO regulatory framework, drafted by the SEC, completed the final round on Jan 22 after being extended twice.
Five companies have expressed interest in becoming ICO portals and more than 15 ICO issuers are preparing to issue digital tokens, said the SEC.
CB Insights said TokenData reported funds raised through global ICOs last year registered 800 deals worth more than US$5 billion (157 billion baht), while funds raised from venture capital tallied 215 deals valued at $1 billion.
Separately, the SEC's Criminal Fining Committee has imposed fines on Mandawee Tour Co Ltd and Prasit Jiewkok for a total of 1 million baht on grounds of publicly offering debenture securities without SEC approval.
Following referrals and an SEC investigation, it was found Mr Prasit, chief executive at Mandawee Tour Co Ltd, held a seminar at a hotel in Udon Thani province in order to solicit investment from some 100 persons, mostly elderly people, urging them to purchase securities of Mandawee Sawasdee Plc.
He claimed the securities were from a merger between Mandawee Tour and Web Sawasdee Plc.
Mr Prasit also claimed Mandawee Sawasdee securities were to be listed on the SET.
