P2P in Thailand: how to avoid someone else's scam and a frozen bank account

This is a practical guide for people who live or spend the winter in Thailand and swap crypto for baht (or the other way round) via P2P.

A Thai bank can restrict your account if money from a fraud chain lands in it, even when you sold your crypto honestly. Since 13 April 2025, the technology crimes decree has allowed transactions on suspicious accounts to be suspended immediately. Three rules lower the risk: payment only from the order owner; one trade, one transfer; screenshots and an e-slip for every trade.

Why Thailand became a “tough” jurisdiction for P2P

In recent years the scale of online fraud in Thailand has shot up: phishing, fake investments, calls from “the bank’s security team”, romance scams, fake brokers. The market for “mule accounts” grew along with it: disposable bank accounts used to run money through.

The state responded with a law. Since 13 April 2025, Emergency Decree No. 2 on measures against technology crimes has been in force: under it, transactions on an account can be suspended immediately if there are credible signs of a link to fraud. The decree also covers digital asset wallets. The Bank of Thailand sorts mule accounts by risk level into black, dark grey, light grey and brown, and that determines how strictly the account is restricted.

When the state puts such systematic pressure on “grey” flows, banks change how they behave:

Any transaction that looks like part of a “chain” (lots of incoming and outgoing payments, identical amounts, odd payment descriptions, frequent transfers from different people) becomes a trigger.
The burden of proof often shifts to whoever received the money: “show us the agreement, show us what the payment was for”.
Freezes are increasingly applied “just in case”, until it’s clear this isn’t part of a fraud.

This matters: in P2P you’re not a “buyer” or a “seller”, you’re a node in a financial graph. And if the graph looks criminal, you’ll be checked as part of that graph.

What a P2P trade really is

At the interface level, P2P is “you sent crypto, they sent you baht”.

At the risk level, P2P is a trade with a stranger who:

may be a fraud victim;
may be a money mule (a mule account);
may be involved in illicit cash-out operations and “grey” schemes;
may later file a complaint to freeze the transaction.

And all of this applies even if the money arrived correctly and fast.

Three main schemes that cost you money or access to your account

The “triangle”: you receive the victim’s money, the scammer gets the crypto

The scenario:

A scammer deceives someone and persuades them to pay “for a service, product or investment”.
In the P2P order, the scammer is your counterparty for the crypto.
But the baht transfer is made by the victim (or by someone the victim asked).
You see the money and release the crypto.

Then the victim realises they’ve been cheated and files a complaint. In the chain, the money is “tied” to your receipt of it, and you become an easy target for pressure.

Why it’s dangerous:

the bank or police see “a transfer to your account” linked to a complaint;
you may be asked to return the amount “as a good-faith recipient”;
holds or freezes are possible until things are cleared up.

Red flags:

the counterparty asks you to accept a transfer from a third party (“a friend”, “my wife”, “an employee”);
several small transfers instead of one (“limits”, “it’s easier this way”);
nervous haste and time pressure.

The “money mule account”: a clean front, dirty money flow

Thailand is actively fighting accounts that are “rented out” or used by criminal groups.

What it looks like from your side:

you sell crypto;
a transfer arrives from an “ordinary” Thai account;
you release the crypto.

And then it turns out that the account is part of a chain (illicit cash-outs, a scam, “grey” money). The result: checks and holds, now on you.

Why it happens more often:

criminals use banks to move money on a massive scale;
“mules” change quickly;
banks react more sharply and faster than before.

Red flags:

the seller’s account looks “perfect”, but the amounts and rhythm of transfers look unnatural;
frequent transfers from different people to your account after a few trades;
odd “rounding” of amounts and repeating patterns.

“A complaint after the trade”: the money arrived properly, but you take the blame

The nastiest scenario for expats.

You did everything “by the P2P rules”:

the sender’s name matched;
the money arrived in full;
you released the crypto.

A day, a week or a month later, a complaint appears:

“I was hacked”
“I didn’t make the transfer”
“I was forced to”
“it’s fraud”

From there, the bank’s anti-fraud system often switches to “emergency mode”: a hold, a request for documents, sometimes blocking part of the amount or the account.

It’s important to understand: a bank is not a court. It chooses to minimise risk. Until it’s clear where the truth lies, the bank will “sit on” the money.

How to lower the risk: a strategy that actually helps

Use legitimate channels wherever possible

Thailand has SEC-licensed exchanges, and the state is pushing the market towards them: since 28 June 2025, Bybit, OKX and several other platforms operating without a Thai licence have been blocked in the country.

And a word about our IT OBMEN exchange. (Site in Russian.) It has been helping our community out for 3 years now: not “random” P2P counterparties but a straightforward service with proven exchange procedures and proper communication. For many people it’s a calmer channel for regular transactions: fewer surprises and less chance of ending up in someone else’s fraud chain by accident.

It’s important to understand: nobody can guarantee that Russian or Thai banks will never ask questions or that blocks never happen at all. But when transactions look logical, have a transparent purpose and are backed by documents, it’s usually easier to pass checks and clear up questions faster.

Even if you still use P2P, it’s worth keeping in mind:

the closer you are to licensed operators, the lower the chance of ending up in a “grey chain”;
unlicensed schemes are more often linked to illicit cash-outs and fraud;
the banking risk is lower when the origin of the money is easier to explain.

If P2P is unavoidable, tighten your filters

Choose counterparties as if you were hiring someone.

The minimum filter:

a large volume of trades and a long history;
a high percentage of successful transactions;
sensible communication without pressure.

The stronger filter (the one that really spares you stress):

No third parties: transfers only from the order owner;
One transfer, one trade: don’t accept “in two parts”;
Amounts without “magic”: avoid odd patterns and repetition.

Protect your Thai bank account

Your Thai bank account is your “centre of gravity”. If it’s frozen, you lose not only money but also the freedom to operate.

In practice:

don’t turn your account into a mini payment terminal (dozens of incoming payments from different people);
don’t run money through your account just “for a better rate”;
don’t mix “personal spending” and regular P2P transactions in one account.

If you need to exchange often, think about structure (a separate account, a separate bank, other channels).

What to record for every trade (so you’re not left without evidence later)

A trade you can’t reconstruct from documents becomes your weak spot.

Save right away:

a screenshot of the order (date, time, amount, username);
a screenshot of the trade chat;
the transfer confirmation (e-slip) with name, amount and time;
a bank statement showing the incoming payment.

If something goes wrong, these four items make a great deal of difference.

What to do if your account is on hold or the money is frozen

Step 1. Don’t panic or scramble to “tie up loose ends”

The main mistake is trying to urgently “cover” the problem with new transfers to “even out the balance”. To anti-fraud systems, that looks like an attempt to muddy the chain.

Step 2. Contact the bank and get the exact reason

Ask for it as specifically as possible:

what exactly is blocked (the whole account, a specific amount, a specific transaction);
what the reason is (suspected fraud, a police request, internal compliance);
whether you need to visit a branch;
which documents are required.

The Bank of Thailand describes the route like this: if you weren’t involved in the offence, contact your bank and bring evidence of good faith. You may have to come to a branch in person. The bank reviews the documents and decides whether to lift the restrictions.

Step 3. Put together an evidence pack

The standard set:

your passport, visa or ID;
bank statements;
trade confirmations (orders, chat, e-slip);
a short written explanation: “what this was and why the money came in”.

Step 4. If it’s about fraud, go through the proper authorities

Fraud reports are taken by the AOC anti-online-scam centre on 1441, questions for the Bank of Thailand go to the 1213 hotline; you can also go to the local police. If the bank says the matter is “a criminal one”, that’s a signal to take the official route rather than argue in the P2P chat.

Step 5. Don’t sign what you don’t understand

If you’re given papers in Thai and you’re not sure what they mean, it’s better to bring in a translator or lawyer. A signed “explanation” can lock in wording that will later be used against you.

A strict checklist for safe trading

Do

use legitimate channels whenever possible;
choose sellers and buyers with a long history and a large volume of trades;
accept a transfer only from the order owner;
record the order, chat, e-slip and statement;
treat your Thai account as an asset you can’t put at risk.

Don’t

don’t accept transfers from third parties;
don’t agree to “two parts” or “it’s quicker this way”;
don’t turn your bank account into a “mini exchange” with daily flows.

Frequently asked questions

Which documents to collect (the minimum “pack” a bank or its compliance team usually asks for)

Collect them right after the trade, not “when you’re up against it”:

Confirmation of the P2P transaction: a screenshot of the order (date, time, amount, username, status).
The trade chat: the key messages (terms, confirmation, that it’s an exchange).
Confirmation of the bank transfer (e-slip): sender’s name, amount, time, reference or transaction ID.
Statement or transaction history: the line with the incoming payment plus the balance before and after.
Your documents: passport, the page with your visa or stamp, a local ID (if you have one), address or lease (if the bank asks for proof of residence or contact details).

If the bank asks about the source of funds:

briefly describe where the crypto came from (salary, savings, a transfer between your own wallets) and attach whatever you have (an exchange or wallet statement, deposit and withdrawal history).

Important: it’s better to have 1–2 pages of calm explanation (in English) with facts: “when”, “how much”, “through which platform”, “what the agreement was”, “what confirmations there are”. No emotions and no unnecessary detail.

What to tell the bank so you don’t make things worse

The bank needs to understand two things: you understand the nature of the transaction and you have evidence.

A working formula (simple and neutral):

“I received a bank transfer in THB as payment for exchanging a digital asset through a P2P platform. I have confirmation of the order, the chat and the e-slip. I’m ready to provide documents for review.”

In addition (if they ask about third parties):

“I don’t accept transfers from third parties; the transfer came from the sender named in the trade”, if that’s true.

What’s best avoided:

“I just sold crypto as usual, I don’t know who sent it”: it sounds like “I don’t care”.
any attempt to “hide” the nature of the transaction: in 2026 this more often makes things worse and triggers a stricter check.

Can you get the money back if the counterparty is a scammer or has filed a complaint

It depends on where you are in the chain and what has already happened.

If you have NOT released the crypto yet (the payment is pending, or you have doubts): record everything, open a dispute on the platform, don’t rush.
If the crypto is gone and the money has been frozen: this is the hardest case. In practice, the possible scenarios are:

the bank keeps the amount on hold until the review or an official request is completed;
the money may be “frozen as evidence” (essentially until the case is decided);
a refund is possible, but usually requires either a ruling on the dispute or confirmation from the authorities.

If you’re being persuaded to “just return the money and it will all be sorted”: this may be an attempt at a second round of the scam.

The rule: don’t make “voluntary” refunds without a clear official framework (a letter from the bank, a case number, a clear procedure). Otherwise you risk:

losing the money while the block stays in place anyway;
becoming the person who “admitted” responsibility, even if you acted in good faith.

What to do if your account suddenly shows a negative balance

We haven’t found an official description of this mechanism; below are observations from the experience of chat members. A negative balance usually means the bank has:

made a temporary adjustment or reservation of the amount for a disputed transaction;
or applied chargeback/claim logic inside its system (not always legally final, but operationally unpleasant).

What to do:

Document what happened: a screenshot of the balance, a screenshot of recent transactions, the date, time and amount of the negative balance.
Contact the bank and ask specific questions: is this a hold or reservation, or a debit? For which transaction? Is there a case, request or file number? What do you need to provide to get it unblocked?
Don’t cover the negative balance with random top-ups until the reason is clear. Sometimes a top-up just disappears into the “black hole” of the reserve and doesn’t solve the problem.

If the negative balance is getting in the way of everyday life (payments don’t go through), discuss with the bank:

partial unblocking or transaction limits;
having your account handled by a branch with an English-speaking member of staff;
an official list of documents and review times.

The bottom line

P2P abroad isn’t “a good rate” but a combined risk: banking and legal.

The main idea is simple:

You don’t control where the counterparty’s money comes from. But you do control your own rules.

If you treat exchange as a process (filters, no third parties, recording evidence, protecting your bank account), you sharply reduce the chance of the most painful scenarios.
