Thailand's crypto ETF rulebook is now final, and it reads like a field manual for how spot crypto funds get built.

The Securities and Exchange Commission finalized the framework on Oct 8. It takes effect Oct 16. Only Bitcoin and Ether qualify at launch, listed exclusively on the Stock Exchange of Thailand, each run as a passive tracker of the underlying asset.

The number that matters: average net exposure to a single crypto asset must hold at no less than 80% of net asset value across the accounting year. That is the enforcement mechanism. An issuer cannot quietly dilute the fund with cash equivalents and keep marketing it as a Bitcoin ETF.

Custody must sit with SEC-regulated digital-asset custodians. No margin loans for purchases. Investors complete a risk briefing and confirm comprehension before trading.

The protectionist layer is deliberate. Depositary receipts linked to foreign ETFs are blocked, brokers cannot steer ordinary retail into overseas crypto ETFs, and mutual funds that previously had to buy abroad can now buy Thai-built funds.

The acknowledged template is American. Bitkub's Attakrit Chimphlapibul pointed to the US spot Bitcoin and Ethereum ETFs on the record. Bangkok's version just routes the flows home. $BTC $ETH
