There are four types of government debt securities in Thailand: (i) Treasury bills; (ii) Government bonds; (iii) Bank of Thailand (BOT) bonds; and (iv) state-owned enterprise (SOE) bonds.

Treasury bills are short-term debt instruments (maturity of less than 1 year), while the other three types are medium- to long-term bonds. Government bonds are issued by the Ministry of Finance (MOF), and are classified into three types: (i) investment bonds, (ii) loan bonds, and (iii) savings bonds. BOT bonds are issued by the central bank (BOT) and SOE bonds are issued by government-owned corporations. Some SOE bonds are guaranteed by the MOF.

Government bonds, BOT bonds, and Treasury bills are issued by competitive price auctions organized by BOT. In 2002, non-competitive bids were also made available, but only for small investors with bids ranging from THB4 million to THB40 million.

SOE bonds are issued by Dutch auction, whereby the issue is awarded to the bidders with the lowest funding cost offer. The auctions are managed by the Public Debt Management Office (PDMO) under the Ministry of Finance.

Corporate bond issuance began in 1992. Before a company issues bonds, it must receive approval from the Securities and Exchange Commission (SEC). The approval is by issuer, so an issuer can offer several bonds at one time.

Securitization developed in Thailand during the period 1993–1998. The Securities and Exchange Act, the Royal Enactment on Special Purpose Juristic Persons for Securitization B.E. 2520 (Securitization Act), BOT Notification 122-2549, and SEC Notification 4/2546 are the major regulations governing the securitization process.

The types of securitization debt issued include asset-backed securities, credit card or personal loan receivables, deposit receipts, and future cash flows.
