Thailand's securities regulator wants to let everyday investors buy Bitcoin (BTC) and Ethereum (ETH) through regulated funds, but its proposed retail crypto ETF rules are designed to steer that money toward locally domiciled products. The draft, opened for public comment on August 24, 2026, would allow only Bitcoin and Ethereum in the first stage and would require each fund to trade on the local stock exchange.

Thailand's Securities and Exchange Commission (SEC) announced that it is seeking public comment on two consultation papers: draft crypto ETF rules and revised qualification rules for foreign custodians — the firms that safely hold a fund's underlying crypto on its behalf. The public hearing on both papers runs through September 20, 2026, after which the SEC will review the feedback before deciding on final rules.

An ETF, or exchange-traded fund, is a basket product that trades like a stock but tracks an underlying asset. Spot crypto ETFs moved into the investment mainstream after US regulators approved spot Bitcoin funds in January 2024 and spot Ethereum funds later that year, with Hong Kong's market adding its own spot crypto ETFs in 2024. Thailand's plan would package Bitcoin or Ethereum into that familiar wrapper, so people can gain crypto exposure through a normal brokerage account instead of a crypto exchange — with no wallet or private keys to manage. Crypto trading is already legal in Thailand through exchanges licensed under the country's 2018 digital asset emergency decree, so the draft would not open crypto ownership to Thais for the first time — it would add a securities-market route aimed at mainstream brokerage investors.

What Thailand Is Proposing

Under the first stage of the draft:

• Only Bitcoin and Ethereum would be eligible assets.
• Each fund would be a passive, single-asset product, meaning it tracks one coin and does not try to beat the market.
• Each crypto ETF would need to keep average net exposure of at least 80 percent of net asset value (NAV) across every accounting year. In plain terms, the fund must stay almost fully invested in its coin rather than sitting in cash.
• The funds would list and trade only on the Stock Exchange of Thailand.
• Before trading, investors would face education and risk-acknowledgment steps, so buyers confirm they understand crypto's volatility first.

Why the Draft Rules Favor Local Funds

The clearest local-preference signal is custody. Under the draft, holding the underlying crypto would remain primarily with SEC-regulated onshore custodians, with qualified foreign custodians permitted only later, when necessary and appropriate. That emphasis on custodianship reflects a concern regulators worldwide have raised since exchange failures such as FTX's collapse in 2022 put a spotlight on where and how digital assets are actually held.

The SEC would also amend its rules so that mutual funds and private funds could invest in Thai-domiciled crypto ETFs, in addition to foreign ones, within existing limits. That opens a new home-grown menu for professional funds alongside the retail channel.

The sharpest protection sits in what the draft blocks. During the initial phase, the SEC would not permit alternative products linked to foreign crypto ETFs, including depositary receipts that reference overseas funds. In practice, that keeps retail money flowing into products built and held inside Thailand rather than into wrappers around US or European ETFs. Local issuers gain first-mover space while outside competitors wait on the sidelines — an approach that continues a pattern seen earlier in the SEC's rulemaking push, when it proposed tighter scrutiny of crypto firm funders.

These terms are still proposals, not finished law. The SEC could revise custody, eligibility, or the foreign-product restriction after the comment period, so final implementation details should not be assumed.

What the Proposal Could Mean for Retail Investors

For a first-time buyer, the appeal is simplicity: a regulated ETF lets someone hold Bitcoin or Ethereum exposure through a normal brokerage account without managing a wallet or private keys. The trade-off is choice — blocking foreign-ETF-linked products during the initial phase limits the range of funds available, even if it channels activity toward domestic oversight.

The draft follows an earlier SEC hearing in April and May 2026, where most respondents supported the broader framework but raised custody concerns. The regulator's broader push also mirrors global moves, such as the US SEC's proposed crypto asset rules. Thailand has separately tightened enforcement, including a crackdown on high-value USDT trades.

The near-term checkpoints are concrete: the September 20, 2026 comment deadline, then the SEC's review of whether the onshore-custody preference, the 80 percent exposure floor, and the block on foreign-ETF-linked products survive into final rules — the details that will shape how much of the local-first design actually reaches investors.

Market conditions frame the timing. During the publication window, Bitcoin traded near $78,587 with a slight 24-hour dip, Ethereum sat around $2,490, and the Fear & Greed Index registered 65, a "Greed" reading.

For anyone in Thailand tracking regulated crypto access, the practical takeaway is patience. Nothing is tradable yet, and the safest step is to follow the SEC's final decision before assuming a local Bitcoin or Ethereum ETF exists.
