According to the bank's anti-money laundering procedures, the bank will look into accounts that somehow have more than $10 million on their cards and will definitely call you to ask you about it. It will also monitor accounts that have large transfers on a regular basis and transfer them out immediately, and will ask you where the money came from. Not being able to answer is a problem, unless you have a lot of personal assets. For some small accounts, surely the bank would ask for a sudden $10 million increase...?

Now personal accounts transferring more than 500,000 per day will be checked by the bank's big data monitoring system. Some are just calls from the bank, some will be directly shut down. So a sudden increase of 10 million will definitely be checked. There are still cases where a bank card suddenly exceeds 10 million dollars, which is usually caused by an error in the bank's system. In this case, however, the bank should be notified immediately and the money should not be spent. In the past, it was a bank loophole that led to this situation. As a result, someone spent the money and the bank told him to return it. That person was convicted without getting it. This should be illegal income. According to Article 20 of the Measures for the Administration of Large-value and Suspicious Transaction Reports by Financial Institutions, financial institutions shall set up full-time anti-money laundering positions with full-time staff in charge of large-value and suspicious transaction reports, and provide the necessary resources and information support. The following transactions are large-value transactions. cash transfer, cash remittance, cash bill settlement and other forms of cash receipts and payments. (ii) Funds transfers with a single or cumulative transaction amount of more than RMB 2 million (including RMB 2 million) and a foreign currency equivalent of more than USD 200,000 (including USD 200,000). According to Article 11 of the Measures for the Administration of Large-value Transactions and Suspicious Transaction Reports by Financial Institutions, if a financial institution discovers or has reasonable grounds to suspect that a customer, the customer's funds or other assets, or the customer's transactions or attempted transactions are related to money laundering and terrorist financing and other criminal activities, it shall submit a suspicious transaction report, regardless of the amount of funds involved or the value of assets involved. To summarize Every bank now has an anti-money laundering department and all accounts are monitored by big data. If you break the rules and the source of the funds is unknown, it will be reported and someone from the anti-money laundering department will ask you about the source of the funds. So a large sum of money suddenly appearing in the account will definitely be asked. If you can't answer the source of funds, it is also possible that the account will be frozen.
