Is it legal for a foreigner to sell USDT for cash in Thailand?

Updated: 17 October 2026

Short answer: there is no simple yes or no, and this page does not pretend to give one. The official Thai statements we found are about businesses that run trading, exchange, transfer or withdrawal services. We found none that settles the question for a private foreigner selling their own USDT. What they do show is where the risk sits: who you sell to, and whether you can document the deal.

Published by OneEx editorial team. Sources, updates and corrections.

This is not legal advice. We are an exchange service, not a law firm. Everything below is a summary of public statements, each linked at the end with its date. Rules change, so check the originals and ask a licensed Thai lawyer about your own case.

What the Thai rules cover

The main law is the Emergency Decree on Digital Asset Businesses B.E. 2561 (2018), enforced by the Securities and Exchange Commission (SEC). Here is what the SEC itself has said in its news releases:

  • A licence is required for providers of services. The SEC says providers of trading, exchange, depository, transfer or withdrawal services for digital assets in Thailand must hold a licence, and it warns specifically about foreign operators without one (SEC, 15 October 2021).
  • What counts as an exchange. The SEC said one foreign website was liable to count as a digital asset exchange because it matched orders, arranged counterparties or provided the system for people to trade (SEC, 2 July 2021).
  • Penalties for operating without a licence. Section 66 provides for 2 to 5 years in prison, a fine of 200,000 to 500,000 baht and a daily fine of up to 10,000 baht while the breach continues (SEC, 24 October 2025). The release states it applies to any person who operates a digital asset business without a licence.
  • Users are not protected. The SEC warns that people who use unlicensed operators have no legal protection and face a higher risk of scams and money laundering (SEC, 29 May 2025).

Recent actions all target platforms and the people behind them:

  • On 29 May 2025 the SEC named five platforms (Bybit, 1000X, CoinEx, OKX and XT.COM) as unlicensed. The Ministry of Digital Economy and Society (MDES) was to restrict access from 28 June 2025 under a royal decree on technological crime in force since 13 April 2025.
  • On 24 October 2025 the SEC and the Cyber Crime Investigation Bureau raided a Worldcoin exchange service at an iris-scanning site and arrested suspects for operating without a licence.
  • On 1 September 2026 the SEC filed complaints against the providers of two apps (Holdstation and UNO) and a supporter for unlicensed brokerage, and asked MDES to block access from 1 October 2026. The release is in Thai.

Notice what these sources do not say. They do not say that a private person selling their own USDT is committing an offence, and they do not say it is allowed. They address businesses. We therefore make no claim either way.

What the Bank of Thailand says

  • Not legal tender, not for payments. The Bank of Thailand states that digital assets are not legal tender and that it does not support using them to pay for goods and services (8 July 2021). Paying with USDT in a shop is not a normal option; you convert to baht first. The SEC's TouristDigiPay sandbox, announced on 18 August 2025, follows the same logic: tourists convert through licensed operators and merchants receive baht.
  • More attention on USDT. In a speech on 3 September 2026 the Governor said the Bank is working with the SEC on safeguards for USDT trading, through stronger customer profiling and the Travel Rule. He also said the Bank has issued 24 suspicious transaction patterns for financial institutions and that restrictions on high-value cash withdrawals have been in place since April 2026.

These are measures for banks and platforms, not rules written for individual sellers. We mention them so that extra questions from a bank or a service do not come as a surprise.

Licensed exchange, P2P, exchange service

RouteWhat the sources sayWhat to check
Operator on the SEC licence listOnly licensed providers may run these services. In the TouristDigiPay sandbox, KYC and customer due diligence under AMLO standards apply to the operators (SEC, 18 August 2025).That the name is on the list. Ask what the platform needs from you to pay out baht, for example a Thai bank account.
Unlicensed platform, Thai or foreignNo legal protection for users, higher scam and money laundering risk. Access can be blocked.Search the Investor Alert list before you send anything.
A person or shop buying USDT for cashNot addressed directly. The Worldcoin case shows that the SEC acts against people who run an exchange service as a business.Ask who you are dealing with. Do not release USDT before the cash is in your hand and verified.

For the practical side of each route, see how to convert crypto to cash in Thailand. A first-time seller can also read the checklist for selling USDT for cash in Phuket.

OneEx is a P2P exchange between individuals. Its site does not state a legal entity or a licence number (see Is OneEx legit?), and nothing on this page should be read as saying that any service, ours included, is licensed or approved by a Thai authority. Before you pay anyone, ask for the operator's details and the terms of your deal in writing. Our own checks are described in the AML / KYC policy: we accept payment only from first parties and may ask about the origin of funds for large or unusual deals.

If you want to see how a USDT to baht deal with OneEx is organised, you are welcome to ask in the Telegram bot. The manager explains the steps, the checks and the payout options before you pay.

Records worth keeping

A bank or a service may ask where the money came from. Having the answers ready is ordinary good practice:

  • the transaction hash, your wallet addresses and the network (TRC20, ERC20 or BEP20);
  • the purchase history or withdrawal history that shows where your USDT came from;
  • the written quote and the chat with the counterparty;
  • the receipt, ATM slip or bank transfer record for the baht you received;
  • a copy of the terms of the service you used.

Tax is a separate question. We do not cover it here; ask a Thai tax adviser how your situation is treated.

How to check a platform yourself

  • Look for the operator in the licence list on sec.or.th or in the SEC Check First app.
  • Search the SEC Investor Alert list for names that are not regulated.
  • To report a suspicious operator, the SEC Complaint Center hotline is 1207.

What we could not confirm

We looked for an official Thai statement that answers the question for a private foreigner selling their own USDT for cash, and did not find one in the SEC and Bank of Thailand material listed below. The licensing rules are written for businesses, and the enforcement we found is against businesses. Where the line between a private sale and an unlicensed service falls is a legal question for a Thai lawyer. This page was last checked on 17 October 2026.

In short

  • Thai licensing rules apply to businesses that run exchange, trading, transfer or withdrawal services.
  • We found no official yes or no for a private foreigner selling their own USDT; this is not legal advice.
  • The SEC says users of unlicensed operators have no legal protection.
  • The Bank of Thailand does not support paying with digital assets and is watching USDT activity more closely.
  • Check licences on sec.or.th, deal in writing and keep your records.

FAQ

Can a tourist legally sell USDT for cash in Thailand?

We cannot give a yes or no, and this page is not legal advice. The Thai SEC statements we reviewed are about businesses that run trading, exchange, transfer or withdrawal services, and we found no official statement that answers the question for a private foreigner selling their own USDT. For a firm answer, ask a licensed Thai lawyer.

Can I pay for things in Thailand with USDT directly?

The Bank of Thailand does not support using digital assets as a means of payment for goods and services (press release of 8 July 2021). The SEC TouristDigiPay sandbox, announced on 18 August 2025, also says digital assets cannot be used directly: tourists convert to baht first and merchants are paid in baht.

How do I check whether a platform is licensed?

The SEC publishes the list of licensed digital asset business operators on sec.or.th and in its SEC Check First app. Names that are not regulated by the SEC can be searched in its Investor Alert list. The SEC complaint hotline is 1207.

What happens if I use an unlicensed platform?

The SEC says that users of unlicensed operators have no legal protection and face a higher risk of scams and money laundering. The SEC releases we reviewed describe enforcement against the operators, such as criminal complaints and access blocking, and do not describe action against their customers.
