Thailand

Emergency Decree on Digital Asset Businesses (2018). Thailand's primary crypto legislation, enacted by Emergency Decree in May 2018, defines 'digital assets' (cryptocurrencies + digital tokens) and establishes the licensing framework for digital-asset exchanges, broker-dealers, dealers, and ICO portals. The Decree creates SEC Thailand as the primary regulator with extensive rulemaking and supervisory powers.

SEC Thailand regulatory style. SEC Thailand operates as a substantively active regulator with prescriptive rules covering custody, AML, customer-asset safeguarding, marketing communications, and product approval. The 2022 Zipmex collapse (a regional exchange with significant Thai customer base that paused withdrawals during the 3AC contagion) drove substantial rulebook tightening through 2023-2024.

Bank of Thailand role. The Bank of Thailand supervises broader monetary-stability matters including stablecoin issuance, cross-border crypto payments, and CBDC research. BoT and SEC Thailand jointly issued the March 2022 ban on crypto-as-means-of-payment for goods and services (with limited exceptions); the policy aim is to maintain THB monetary sovereignty.

SEC Thailand digital-asset business licences. Operators of digital-asset exchanges, broker-dealers, or dealers must hold SEC Thailand licences. Each licence has its own capital requirement, governance standards, AML / KYC programmes, customer-asset safeguarding, custody arrangements, cybersecurity standards, and ongoing supervisory engagement. The licensing process typically takes 12-24 months.

Custody requirements. SEC Thailand rules require licensed exchanges to safeguard customer digital assets with at least 90% in cold storage and the remainder in hot storage subject to insurance / capital reserves. Post-Zipmex, custody-segregation requirements were further tightened.

ICO portal licensing. A separate licence category covers ICO portals — platforms through which approved digital-token offerings to Thai investors may be conducted. The portal must screen offerings, verify investor accreditation where required, and meet specific operational standards.

BoT-issued guidance. The Bank of Thailand has historically taken a cautious posture on private stablecoins, particularly THB-pegged stablecoins. Major THB-pegged stablecoins have not been licensed; the de facto policy has been to direct stablecoin-equivalent functionality through the licensed-bank payment infrastructure rather than private issuance.

Foreign-currency stablecoins. Foreign-currency stablecoins (USDT, USDC, etc.) may be traded on SEC-licensed exchanges as digital assets but are not approved as means of payment for goods and services in Thailand under the March 2022 framework.

CBDC research. The Bank of Thailand has been active in CBDC research, including pilots of retail-CBDC use cases and the wholesale-CBDC Inthanon project (with the Hong Kong Monetary Authority and others). Retail CBDC roll-out is in pilot phase as of mid-2026 with no formal launch announced.

15% withholding tax on crypto profits. The Revenue Department classifies crypto-trading profits as 'assessable income' subject to a 15% withholding tax. Licensed exchanges withhold and remit; individual taxpayers report the trading activity in their annual return and are taxed at marginal rates up to 35% (with credit for the 15% already withheld).

Loss offset (limited). Crypto losses can offset crypto gains within the same tax year but cannot offset other income categories and cannot be carried forward to subsequent years. This treatment is broadly equivalent to Japan's restrictive loss-handling rules.

Mining and staking. Mining and staking rewards are assessable income at fair-market value on receipt. Salary received in crypto is employment income at the receipt value.

This is general background, not tax advice. Consult a Thailand-qualified tax adviser for personal tax matters.

AMLO (Anti-Money Laundering Office) framework. Licensed digital-asset businesses are reporting entities under Thailand's Anti-Money Laundering Act. Customer due diligence, transaction monitoring, suspicious-transaction reporting, and recordkeeping are mandatory.

Travel Rule. Thailand implemented Travel Rule requirements in 2023 broadly aligned with FATF Recommendation 16. Originator and beneficiary information accompanies transfers between licensed Thai exchanges.

Sanctions framework. Thailand implements UN-mandated sanctions plus targeted measures. Licensed digital-asset businesses screen against the AMLO consolidated sanctions list. Russia-related autonomous sanctions are limited; Thailand has not adopted the broader US / EU Russia sanctions framework.

Post-Zipmex tightening. Following the 2022 Zipmex withdrawal-freeze, SEC Thailand: tightened customer-asset segregation rules; introduced stricter custody-audit requirements; expanded supervisory inspection frequency; introduced specific marketing-restriction guidance.

Investment-product approval. Digital-token offerings to Thai retail investors require SEC Thailand approval (typically via an ICO portal). Approval involves disclosure-document review, project assessment, and ongoing post-issuance reporting requirements.

Marketing rules. SEC Thailand restricts misleading promotional language. Yield-promise marketing (e.g., 'X% APY') is constrained; comparative claims against fiat / traditional investments must include risk disclosure.

SEC supervisory reporting. Licensed digital-asset businesses submit regular returns to SEC Thailand covering transaction volumes, customer counts, customer-asset balances, AML statistics, and customer-complaint metrics.

Revenue Department visibility. Revenue Department receives 15% withholding-tax data from licensed exchanges, providing routine visibility into trading activity on domestic licensed venues. Cross-border data sharing under OECD CARF is on a 2027-2028 implementation track.

Enforcement against unlicensed activity. SEC Thailand has been notably active in issuing warnings against unlicensed foreign exchanges targeting Thai customers; multiple foreign exchanges have geo-blocked Thai users in response to SEC Thailand enforcement notices.
