Thailand drafts a deliberately narrow crypto ETF regime, and the comment window shuts September 20

The narrowness looks deliberate rather than provisional. The draft admits only Bitcoin and Ether and would list the funds only on the Stock Exchange of Thailand ^[3][5]. Each is required to passively track a single coin while holding at least 80% average net exposure to it across the accounting year ^[4]. Read the other way, up to a fifth of a fund can sit in cash or tracking slack ^[19], but a single-coin passive mandate rules out baskets and active management by construction ^[4].

The one piece of the design that actually moved between the April and August drafts is custody ^[9]. The new version keeps onshore, SEC-regulated custodians as the default and admits qualified foreign custodians only "when necessary and appropriate in light of prevailing circumstances," with those custodians also permitted to act as mutual fund supervisors ^[6][7]. Before a foreign custodian can hold anything it has to clear its home regulator, sit under an authority with real legal power, and satisfy Thai asset-protection standards ^[8]. The door exists; the SEC holds the key and has written itself room to leave it shut.

Underneath the structure sits a tax break the SEC is trying to route through supervised wrappers. Thailand has held capital gains on crypto at 0% from the start of 2025 to the end of 2029 ^[16], a five-year run ^[18], and the regulator frames the ETF regime as another channel for pulling demand into regulated products ^[17]. Domestic mutual and private funds will be able to hold the local ETFs alongside foreign ones they already own, still subject to existing limits ^[12].

None of this is decided. The consultation sits at least two steps from a rulebook: the SEC collects comments, revises, then decides whether to authorize the products at all, with no approval or launch date committed ^[10]. Thailand already cleared a spot Bitcoin ETF in June 2024, for institutions only ^[14], and in January a deputy secretary-general said the products had approval in principle and would ease the hacking and wallet worries that keep some buyers out ^[15]. The direction is set; what is still open is the terms.
