There are two secondary bond markets in Thailand: the over-the-counter market under the Thai Bond Market Association (ThaiBMA), formerly the Thai Bond Dealing Centre (Thai BDC), and the Bond Electronic Exchange (BEX).

The ThaiBMA has three types of members:

• Ordinary members–financial institutions with a debt-trading license (dealer);
• Extraordinary members–companies that have inter-dealer broker licenses (IDBs);
• Associate members–firms that facilitate trades to an ordinary member with a monthly average trading value in each of the past 12 months of less than THB100 million.

BEX has an electronic bond-trading platform overseen by the Stock Exchange of Thailand (SET). Brokerage firm members trade corporate bonds issued by SET-listed companies on behalf of their clients. The SET link below lists brokerage firms in the exchange.
