What Happens When You Transfer From a Crypto Exchange to a Bank
When you withdraw fiat from a cryptocurrency exchange (Binance, Coinbase, Kraken, etc.) to your bank account, the bank sees an incoming transfer. More and more banks automatically identify the source of such transfers and may reject them or freeze the recipient's account.
Why It Happens
Bank's AML policy. Cryptocurrency exchanges and brokers fall into the high-risk category from an AML perspective. Banks are required to verify the source of funds, and transfers from crypto companies are often automatically flagged for review.
No formal relationship with the exchange. Many traditional banks have no contractual relationship with crypto exchanges and simply refuse their transfers as a matter of business policy.
Customer profile mismatch. If your bank sees an unusual incoming transfer from a crypto company that does not fit your declared profile, it will trigger a source-of-funds inquiry.
Country regulatory requirements. In some countries, banks are required to decline or block transfers from unlicensed crypto exchanges.
Exchange's reputation. If the exchange has previously been involved in investigations or received negative regulatory assessments, its transfers may be automatically blocked.
What to Do
Ask the bank for the specific reason. Request a written explanation of the rejection. The bank is obligated to provide a reason (even if general).
Prepare source-of-funds documentation. Export your transaction history from the exchange, confirm the cryptocurrency purchase, and provide a tax return if applicable. This is known as Proof of Source of Funds.
Use reputable exchanges in your region. Locally licensed crypto brokers often have established banking relationships. Coinbase or Kraken in the EU are preferable to an unfamiliar exchange.
Try a crypto-friendly bank. Some banks and neobanks (Revolut, N26, certain EMIs) are more accommodating with cryptocurrency-sourced transfers.
Reduce the single transfer amount. Smaller regular transfers attract less scrutiny than one large amount.

FAQ
Can the bank close my account because of a crypto transfer? Yes. If the bank determines that you are violating its policy or represent an AML risk, it may terminate the relationship. This is why it is important to clarify the bank's crypto income policy in advance.
Do I need to declare cryptocurrency income? In most countries, yes. Income from selling crypto is taxable (as capital gains or ordinary income). Having a tax return significantly simplifies the bank's review process.
Does a letter from the exchange explaining the transfer help? Yes. Many exchanges provide official attestation letters for banks. Request one through your exchange's support team.
