Thailand advances spot Bitcoin and Ether ETF rules with 80% exposure floor

Thailand’s regulator has advanced draft rules permitting spot Bitcoin and Ether ETFs that require funds to maintain at least 80% exposure to the underlying cryptocurrencies. The exposure floor locks ETF holdings predominantly into physical BTC/ETH rather than derivatives, increasing the likelihood of direct on‑exchange demand for the tokens. This regulatory move provides clearer on‑ramp for institutional and retail investors in Thailand and signals growing regional acceptance, which could support price and liquidity for Bitcoin. The 80% constraint also limits managers’ flexibility for cash management and hedging, potentially affecting product design and volatility management.
