Understanding Anti-Money Laundering Regulations

AML Regulations: The Institutional Root of Card Freezing

Bank card freezing isn’t the bank being “malicious” — it’s required by anti-money laundering regulations. Understanding the regulations helps you understand why freezes happen.

Core Regulations

Anti-Money Laundering Law (Revised 2006)

• Banks must monitor suspicious transactions
• Large transactions (>50,000 CNY) must be reported
• Banks have the right to freeze suspicious accounts

Financial Institution AML Provisions

• Banks must establish AML monitoring systems
• Systems automatically identify suspicious transaction patterns
• Suspicious transactions must be reported to the central bank and police

Cryptocurrency-related regulations

• 2021: Central bank clarified that cryptocurrency trading is not legal in China
• Banks mark cryptocurrency-related transactions as high-risk
• P2P transactions involving crypto = banks may view them as suspicious

How AML Systems Work

Bank AML systems monitor three dimensions:

1. Amount Dimension

• Single transaction >50,000 CNY: auto-flagged
• Monthly cumulative >200,000 CNY: auto-flagged
• Frequent large in-and-out flows: auto-flagged

2. Frequency Dimension

• 3 transfers to the same person in one day: flagged

• Dense transactions in a short period: flagged
• Frequent late-night transactions: flagged

3. Association Dimension

• Counterparty already flagged: your transaction auto-linked
• Counterparty involved in a case: your account chain-frozen
• Funds flowing in and out quickly: suspected money laundering path

Suspicious Transaction Reporting System

After a bank discovers a suspicious transaction:

1. Internal review (1-3 days)
2. Report to central bank AML monitoring center
3. Report to police (if criminal activity suspected)
4. Freeze related accounts

This is the freeze process: AML system → flag → report → freeze.

How Retail Traders Can Stay Compliant

Core principle: Make AML systems unable to see your crypto transactions

Method	AML Visibility	Freeze Probability
Bank transfer to crypto merchant	100% visible	5-10%
Alipay P2P	Not visible (third-party payment)	0.1%
WeChat P2P	Not visible	0.1%
Offline cash	Not visible	0%

Why is Alipay/WeChat P2P “not visible”? Because the fund flow passes through a third-party payment platform — the bank only sees “Alipay → merchant”, not “you → crypto merchant”.

Legal Risk Boundaries

Gray area:

• Personal holding of cryptocurrency: not illegal
• Personal P2P buying/selling of USDT: gray area (no explicit prohibition)
• Cryptocurrency exchanges: not allowed to operate in China

Red lines:

• Using large bank transfers to buy crypto: triggers AML
• Buying/selling crypto on behalf of others: suspected of assisting money laundering
• Fake transactions/wash trading: suspected fraud

Retail traders doing small personal P2P transactions are in the gray area with manageable risk. But large bank transfers are a red line.

Compliant Suggestions for Safe Deposits/Withdrawals

1. Only use Alipay/WeChat P2P (no bank transfers)
2. Keep each transaction under 5,000 CNY (avoid triggering bank risk control)
3. Choose certified merchants (clean fund sources)
4. Keep records (in case you need to appeal)
5. Don’t buy/sell on behalf of others (avoid suspicion of assisting money laundering)
