Table 5. Thailand: Summary Implementation of the IOSCO Principles—Detailed Assessment (concluded) Principle Findings Principle 35. Regulation should promote transparency of trading. Current practice in SET and TFEX provides adequate pre-trade and post-trade transparency. Respecting the OTC bond trading, TBMA ensures appropriate post-trade transparency, but there is no pre-trade transparency in this market segment. Principle 36. Regulation should be designed to detect and deter manipulation and other unfair trading practices. As discussed previously, the SEC should obtain real-time online access to existing SRO surveillance systems and develop its own surveillance team to augment and complement the current SRO programs. Consideration should also be given to merging the SET and TFEX surveillance programs. It is recommended that the TBMA surveillance and enforcement programs should be examined carefully. As discussed previously there may be serious validation issues with dealer-customer trade reporting, which accounts for 80 percent of daily trading. Once the new amendments to the SEA become effective, the SEC will have authority over SET trading and operating rules. Short-term retail investor trading is a substantial portion of SET daily trade volume and licensed intermediaries rely heavily on trade commissions and fees for revenue. This may be an appropriate point in time for the SEC to conduct a comprehensive examination of all SET trading and operating rules and their interaction and influence on the common trading practices on the SET. Principle 37. Regulation should aim to ensure the proper management of large exposures, default risk and market disruption. The SET and TFEX, monitor the risks of its members (at member level) and put in place the measures to identify, monitor, and evaluate large exposures. The TCH has tools to manage exposures by its members by requiring collateral according to the risk assumed by them. Short-selling is regulated and naked short-selling prohibited. Exchange traded derivatives are cleared through TCH while OTC traded derivatives are not. The authorities believe that the size of this market segment is not large enough to justify making centralized clearing mandatory. The SEC and BoT should develop a roadmap for mandating central clearing of OTC derivatives. Central clearing addresses the inherent systemic risks arising from bilateral clearing and is consistent with the IOSCO Principles and international best practices. Principle 38. Securities settlement systems and central counterparties should be subject to regulatory and supervisory requirements that are designed to ensure that they are fair, effective and efficient and that they reduce systemic risk.
