The Securities and Exchange Commission has set rules, effective Friday, allowing crypto ETFs to be created and traded on the Stock Exchange of Thailand. Initially they can hold only Bitcoin and Ethereum, with custody by SEC-licensed custodians. Thai mutual funds and private funds can now invest in locally listed crypto ETFs. Overseas crypto ETF-linked products remain barred for now. For a typical SME owner this is background only: no tax, cost or lending change, and no action needed unless you manage investments or hold digital assets.
