Thailand Sets October 16 Start for Bitcoin and Ether ETF Rules, Restricts Foreign Access

New Rules Open the SET, but No Fund Has a Launch Date

Thailand's Securities and Exchange Commission has issued 11 regulatory notifications allowing locally established Bitcoin and Ether exchange traded funds on the Stock Exchange of Thailand, with the framework taking effect on October 16, 2026. Each fund must passively track one cryptocurrency and maintain average net exposure of at least 80% of its net asset value to that asset over each accounting year.

The SEC announced the rules on October 8 after two rounds of public consultation. Bitcoin and Ether, the cryptocurrency of the Ethereum network, are the only assets eligible initially. The framework also requires regulated custody, investor risk education and a ban on brokerage margin loans for purchases of these ETFs.

October 16 is the effective date of the rules, not a confirmed first day of trading. No individual Bitcoin or Ether ETF has yet been approved or assigned a trading date. The distinction matters: permission to establish a category of fund does not mean a product is ready for investors to buy.

A Domestic Route With Limits on Foreign Alternatives

The framework creates a way to gain cryptocurrency exposure through a security traded on Thailand's main stock exchange. Investors would buy ETF units rather than acquire and store Bitcoin or Ether themselves. The fund and its service providers would handle the underlying investment and custody arrangements.

Eligible ETFs must be established locally and listed exclusively on the SET. At the same time, the SEC is limiting competing routes into foreign crypto ETFs during the initial phase, including depositary receipts and certain other linked products. A depositary receipt is a locally traded certificate representing exposure to a security listed overseas.

The brokerage restriction has an important exception. Securities companies may arrange foreign crypto ETF investments for institutional or ultra high net worth clients, but not for clients outside those categories. This is narrower than a blanket ban on all overseas crypto investments. It directs ordinary investors toward domestic products while preserving specified access for qualifying clients.

What the 80% Requirement Actually Means

Each ETF must operate as a passive investment vehicle seeking to follow the price of a single eligible cryptocurrency. It cannot use the new permission to run an active trading strategy or offer a mixed Bitcoin and Ether portfolio under the stated single asset structure.

The exposure requirement is measured as an average over each accounting year. Net asset value, or NAV, is the value of a fund's assets after subtracting its liabilities. For illustration, if a fund's NAV stayed at 100 million baht throughout an accounting year, average net exposure to its chosen cryptocurrency would have to be at least 80 million baht.

That annual measurement is more precise than saying the fund must always hold exactly 80% of its assets in cryptocurrency. The rules specify a minimum average exposure, not a fixed allocation. They also do not establish that every fund will deliver an exact match to the cryptocurrency's price at every moment. Fees, operating arrangements and the eventual product structure will matter when investors assess tracking performance.

Risk Education and a Ban on Margin Financing

Investors must receive education about the characteristics and risks of crypto ETFs before trading. They must also acknowledge and confirm that they understand the relevant risks. The requirement puts a formal check between access to a securities account and the ability to buy these products.

Securities companies providing trading services must stress appropriate asset allocation, avoidance of concentrated digital asset exposure and investment decisions consistent with each client's risk tolerance. Holding cryptocurrency through an ETF changes how the investment is accessed and stored; it does not remove the risk of a sharp fall in the underlying asset's price.

Brokers cannot provide margin loans to finance purchases. Margin financing allows a client to invest using money borrowed from a broker, increasing exposure beyond the cash committed. The restriction follows Thailand's existing approach to lending for cryptocurrency purchases through digital asset operators. It addresses one source of borrowing risk, without making the ETFs low risk investments.

Custody and Disclosure Become Central Requirements

Digital assets held by the ETFs must be safeguarded by custodians regulated by Thailand's SEC. A custodian is responsible for keeping the fund's assets secure. For cryptocurrency, that includes arrangements governing access to the digital holdings, a task investors would otherwise need to manage themselves or entrust to a trading platform.

An asset management company seeking to establish a crypto ETF must demonstrate adequate personnel, operational systems and arrangements with service providers. The requirement makes organisational readiness part of the approval process, rather than treating the ability to buy cryptocurrency as sufficient preparation to run a listed fund.

Managers must disclose enough information for investors to understand a fund's characteristics, structure, investment mechanisms, service providers and specific risks. These disclosures will be essential for comparing products once applications emerge. The announced framework does not yet provide individual fund fees or operating details.

The SEC may later permit qualified foreign digital asset custodians where it considers their use necessary and appropriate. That is a possible future allowance, not part of the initial custody permission. The starting framework keeps digital asset custody within the regulator's licensed system.

Who Can Manage and Supervise the Funds?

Thai asset management companies may outsource digital asset investment management, but only to licensed digital asset fund managers. This allows a conventional fund manager to use specialist services while keeping the outsourced investment function under regulatory oversight.

Qualified digital asset custodians and other eligible digital asset businesses may also apply to register as mutual fund supervisors for crypto ETFs under Section 121 of the Securities and Exchange Act B.E. 2535 (1992). The registration route brings specialist digital asset businesses into a role within Thailand's securities framework.

These supervisors must meet requirements covering financial standing, personnel and operational systems, and maintain that readiness throughout their appointment. A supervisor registered through this route may supervise only crypto ETFs. If it appoints another custodian to safeguard assets, the digital asset custody must still be performed by a licensed digital asset custodian.

Existing Thai Funds Gain a New Investment Option

The SEC has also amended the rules for Thai mutual funds and private funds. They may now invest in locally established crypto ETFs, subject to their existing investment limits. Previously, their permitted crypto ETF investments were confined to foreign products.

This change gives domestic ETFs a potential investor base beyond people purchasing units directly through brokers. Existing funds may be able to use local products for permitted cryptocurrency exposure instead of relying exclusively on overseas ETFs. Permission to invest does not, however, establish how much money they will allocate.

The combination of expanded domestic eligibility and restricted foreign access serves two stated regulatory aims: developing Thailand's crypto ETF market and strengthening the capabilities of local financial businesses. It creates potential roles for asset managers, custodians, licensed digital asset fund managers and fund supervisors. The eventual size of that market will depend on which products receive approval and attract investors.

A Large Foreign Market Provides a Comparison

Figures for October 12 put combined net assets in United States spot Bitcoin and Ether ETFs at about $121 billion. Those products had attracted approximately $70.37 billion in cumulative net inflows since their launches, providing a measure of the established market Thailand's domestic framework would enter.

The two figures describe different things. Net assets measure the value held by the funds at a particular time. Cumulative net inflows measure investor money entering the products after accounting for withdrawals. Changes in cryptocurrency prices mean asset values can rise or fall without an equivalent change in investor contributions.

These figures are not a forecast of demand in Thailand. Local product approvals, investor eligibility, costs and trading conditions will determine the Thai market's development. Restrictions on some foreign alternatives also make the fees, liquidity and tracking quality of domestic ETFs especially relevant for ordinary investors who cannot use brokerage services to buy overseas competitors.

The Consultation Timeline and Decisions Still Pending

The SEC's final framework followed consultations on both the proposed principles and the draft regulations. The regulator said most respondents supported the proposals. The sequence separates the development of the rules from the product approvals still needed before investors can trade a local Bitcoin or Ether ETF.

• April to May 2026: The SEC consulted on the proposed principles for crypto ETFs and related management and supervision arrangements.
• August to September 2026: A second consultation covered the draft regulatory notifications.
• October 8, 2026: The SEC announced 11 notifications establishing the framework.
• October 16, 2026: The notifications take effect. No individual ETF trading date has been announced.

Any future expansion beyond Bitcoin and Ether will depend on criteria including liquidity, broad market acceptance, network security and investor protection. Liquidity concerns how readily an asset can be traded without causing a large price movement. The SEC has not identified the next eligible cryptocurrency or set a date for expanding the list.

Several practical details remain undecided publicly: which asset managers will launch products, what their fees will be, which service providers they will appoint and when trading will begin. There is also no announced timetable for accepting qualified foreign custodians or changing the initial restrictions on foreign linked products.

For investors, the immediate development is therefore a regulatory opening rather than an available new investment. The framework places cryptocurrency exposure inside Thailand's listed fund system, with local custody and additional trading safeguards. Product approvals and disclosures are the next steps needed to show how that permission will work in practice.
