About ThaiBMA

The Thai Bond Market Association (ThaiBMA)
The Thai Bond Market Association (ThaiBMA) is a securities business related association under the Securities and Exchange Commission Act B.E. 2535. Its main purposes are to be a self-regulatory organization (SRO) for a fair and efficient operation of the bond market and to be an information center for the Thai bond market. It also plays functional roles on market development, market convention and standards and being Bond Pricing agency for the industry. In addition, ThaiBMA provides a forum through which industry professionals can response to current issues and play a role in shaping the future of the Thai bond market.
Although the ThaiBMA was granted a securities business related association and SRO status from the SEC in September 2005, its foundation has started for more than a decade. The first stage of its operation was in November 1994, when it was set up as The Bond Dealers Club (BDC) under the Association of Securities Companies. The BDC played roles as the first and only organized secondary market for bonds and it introduced an electronic bond trading system called ‘Bondnet” for the first time in the history of the Thai bond market. After 3 years of its successful operation, BDC changed its legal status to be in line with its membership structure and to support a more expansive bond market. So it was restructured as the Bond Exchange under the SEC Act and renamed as The Thai Bond Dealing Centre (Thai BDC) in April 1998. The primary roles of the Thai BDC are to facilitate the operation of the secondary market for bond trading and to be a forum for discussing issues on bond market development. One of its missions is to move towards a full self regulatory organization (SRO) to oversee the orderly function of the bond market.
ThaiBDC had continuously expanded its functions and had taken active roles in various area of bond market development. In December 2004, the Bond Market Development Committee chaired by the Finance Minister initiated a major reform of the Thai bond market. One of the measures was to centralize the trading platform at the Stock Exchange of Thailand (SET) while ThaiBDC would remain and expand its functions as the SRO and information center for the bond market. Under this policy, ThaiBDC has sold its newly developed electronic trading platform to the SET in 2005. And to reiterate its focus on SRO functions and information center, ThaiBDC with the support from SEC has changed its status and was granted the license of a securities related association under the SEC Act named as “The Thai Bond Market Association (ThaiBMA) ” on September 8, 2005 .
