The Thailand Securities and Exchange Commission has amended private fund regulations to tighten and clarify disclosure and reporting to investors, while allowing more flexibility in how firms report portfolio information to different investor types. The changes cover Private Fund Standard Portfolio disclosure, reporting of individual investment portfolio status, and conflicts of interest, with the stated aim of ensuring investors receive sufficient information for decision-making without imposing unnecessary burden on business operators. The amended notifications were published in the Government Gazette and took effect on 16 July 2026. The revised rules require Private Fund Standard Portfolio disclosures to be clear, transparent and not misleading on investment policy, type, risks and returns. Where past performance is used in advertising, firms cannot selectively show only favorable periods and must present the information clearly and accurately. Portfolio status reporting may now be tailored to investor type and service model, provided investors still receive the essential information needed to monitor investment performance and status. On conflicts of interest, the amendments set clearer guidance for cross trades between funds or clients under the same management, aligned with the approach used for mutual funds, and require disclosure of fees, remuneration or other benefits that could give rise to conflicts across private funds and provident funds.
