Thai SEC Issues Rules for Bitcoin and Crypto ETF Trading

Thailand’s SEC has issued draft rules for Bitcoin and crypto ETF trading, opening public consultation on August 24, 2026, that would allow locally listed spot Bitcoin and Ether ETFs under strict custody, exposure, and listing requirements.

Key Takeaways

• Thailand's SEC opened two public consultations on August 24, 2026, covering draft rules for locally listed spot Bitcoin and Ether ETFs and separate qualification standards for foreign digital asset custodians, with feedback open until September 20.

• Only Bitcoin and Ether will be eligible underlying assets during the initial phase, and approved ETFs must maintain at least 80% net asset value exposure to the tracked asset and trade exclusively on the Stock Exchange of Thailand.

• The SEC revised its custody approach after April feedback, keeping onshore Thai custodians as the primary option while allowing qualified foreign custodians only when the regulator deems it necessary and appropriate.

What Thailand's SEC Is Proposing

Two separate consultation papers

Thailand's Securities and Exchange Commission is seeking public feedback on two distinct proposals. The first contains draft regulations specifically for Thai-listed spot crypto ETFs.

The second sets out qualification principles for foreign digital asset custodians used by mutual and private funds that invest in digital assets. Both consultation papers opened around August 24, and public comments will remain open until September 20, 2026.

Bitcoin and Ether only, for now

During this initial phase, asset managers would only be permitted to launch passive ETFs tracking either Bitcoin or Ether, the two assets eligible under the draft framework. 

The SEC has indicated it plans to evaluate additional cryptocurrencies for future inclusion based on factors like liquidity, market adoption, network security, and investor protection standards, but no other assets are part of this current proposal.

Strict exposure and listing requirements

Approved crypto ETFs would need to maintain an average net asset value exposure of at least 80% to their tracked cryptocurrency over each accounting year, a threshold designed to keep fund performance closely aligned with the underlying asset's actual price movement. 

These ETFs would also be required to trade exclusively on the Stock Exchange of Thailand, rather than through over-the-counter arrangements or other venues, and each proposed fund would track a single cryptocurrency rather than a basket of assets.

Custody Rules: Why They Changed

What the April feedback revealed

This latest draft follows an earlier April 2026 consultation that focused on the framework's broader principles, including investment management and custody arrangements. 

The SEC said most respondents supported the overall framework, but custody arrangements drew the most substantive feedback, prompting the regulator to revise its original approach before finalizing this next round of draft rules.

Onshore custodians remain the default

Under the revised approach, the SEC stated that crypto ETFs will continue to be primarily required to use onshore digital asset custodians, while the regulator may permit qualified foreign custodians when necessary and appropriate given prevailing circumstances. 

In practice, that means Thai-licensed custody providers remain the default choice for holding ETF assets, at least in this initial phase of the framework.

Standards for foreign custodians, if used

Under the separate custodian proposal, any foreign providers serving mutual and private funds investing in digital assets would need to be supervised by a regulatory authority with genuine legal powers. 

They would also have to operate under regulatory and investor asset protection standards that the Thai SEC considers adequate, effectively setting a high bar for any international custodian hoping to serve this market.

No Foreign ETF Wrappers, At Least Initially

One notable restriction in the draft rules is what won't be allowed at launch. The SEC has said it will not permit alternative products tied to foreign crypto ETFs during this initial stage, including depositary receipts that track ETFs listed on other exchanges. 

That keeps locally established, Thai-domiciled funds as the primary structure available to domestic investors seeking this type of exposure, rather than allowing indirect access to products like U.S.-listed spot Bitcoin ETFs.

Why This Matters for Thailand's Crypto Market

Thailand's SEC has been building toward this framework as part of a broader effort to position the country as a digital asset hub for institutional investors. 

Channeling Bitcoin and Ether exposure through regulated, exchange-traded vehicles rather than direct crypto exchange access could widen institutional participation, since ETFs fit more naturally into existing mutual fund and brokerage infrastructure that many institutional investors already use. 

How the SEC ultimately defines "necessary and appropriate" circumstances for foreign custodians will be worth watching closely, since that language could determine whether early ETF sponsors face friction bringing in international custody arrangements or whether Thailand's onshore custody capacity proves sufficient for the first wave of approved listings.

Conclusion

Public comments on both the crypto ETF draft rules and the foreign custodian qualification standards remain open until September 20, 2026. 

After the consultation period closes, the SEC will review feedback before finalizing the regulations, a process that will determine the actual rules asset managers must follow before any Thai-listed Bitcoin or Ether ETF can launch.
