I’ve only been in Madrid for a few years, and lately, I’ve been hearing more and more friends complain about their bank accounts being frozen. Some have even had their savings investigated, which is causing a lot of anxiety. Everyone is wondering if the banks are cracking down on ‘money laundering’ again, specifically targeting the Chinese community. This issue, while it might seem small, is a big deal because it involves our hard-earned money. So, I wanted to start this post to discuss the situation with everyone, share some of my personal views on different Spanish banks, and explore how we, including users of services like Correos Cash, can avoid these pitfalls.

Actually, the so-called ‘anti-money laundering’ measures by banks are not new policies from the last couple of years; they are regulations that have always been in place. It’s just that in recent years, both the Spanish government and the EU have become much stricter. As the executing bodies, banks are responsible for monitoring the flow of funds in all accounts. Once the system detects an ‘unusual’ transaction—such as a sudden large cash deposit, frequent transfers of the same amount, or transactions with high-risk regions—it can easily trigger an alert. To avoid liability, the bank’s first reaction is often to freeze the account and ask the owner to provide proof of the source of funds. Many of our compatriots, due to language barriers or finding the process troublesome, fail to communicate effectively and promptly with the bank, causing the issue to become more complicated over time.
Which Activities Are Likely to Get Your Bank’s Attention?
Based on my experiences and those of my friends, here are a few common ‘high-risk’ operations you can check for yourself:
- Frequent large cash deposits: Especially cash deposits that don’t correspond with a clear payslip. This is a primary target for bank monitoring systems.
- Improper currency exchange practices: Exchanging money through unofficial channels and then having different people make separate deposits into your account can easily be identified as an organized money laundering scheme.
- Lending or borrowing accounts: Using your account for someone else’s transactions, or receiving money in someone else’s account, is legally very risky.
- Rapid fund movement: When a sum of money is quickly transferred out shortly after being deposited, especially to multiple different accounts, it will also be flagged as a suspicious transaction.
How to Operate Correctly and Avoid Trouble
Ultimately, as ordinary people, we don’t need to worry too much as long as our actions are legitimate and our financial records are clear. The key is to develop good banking habits. Whether you’re a business owner or a salaried employee, you should try to make your fund flows traceable. Below are some personal suggestions, which may not be entirely perfect, but can serve as a reference.
Quick Guide: Common Banks and How to Deal with Them
| Bank Name | Characteristics | Suggested Actions |
| Santander | One of Spain’s largest banks, with a strict system | Try to use your card for purchases and keep all transaction receipts |
| BBVA | Good app experience, but also very strict risk control | Avoid making large online transfers at night or outside of business hours |
| CaixaBank | Many branches, relatively more lenient with small cash deposits | When depositing cash, it’s best to have it correspond with business revenue and keep invoices |
When living abroad, abiding by local laws and regulations is the most fundamental and important thing. Don’t try to engage in grey-area practices for temporary convenience or small gains. Banking systems are becoming more intelligent, making it increasingly difficult to find loopholes. I hope everyone’s accounts stay safe and sound.
