How to Prove Source of Funds When Your Bank Freezes an Exchange Deposit

30 October 2026

Your bank has frozen a deposit you sent to a transfers/domestic-wire-transfer-exchange-deposit/">crypto exchange. The money is stuck, and the bank wants proof that the funds came from a legitimate source before they release it. The process for proving source of funds depends on whether the freeze happened at the sending bank, the receiving bank, or an intermediary, but the documents you need to produce are the same in all cases: evidence of the transfer's origin and purpose, plus proof of your identity and the source of the money itself.

Why banks freeze exchange deposits

Banks freeze deposits to crypto exchanges because of their legal obligations under anti-money laundering (AML) and counter-terrorism financing (CTF) regulations. When a deposit matches patterns the bank's monitoring system flags - such as a large amount to an exchange you haven't used before, multiple rapid transfers, or a deposit from an account that normally holds savings rather than checking - the system pauses the transaction. The bank then asks you to prove the money is yours and wasn't obtained through illegal activity.

The freeze can happen at three points: - At your bank (the sending bank) before the funds leave your account - At the exchange's bank (the receiving bank, often an omnibus account) after the deposit arrives but before it's credited - At an intermediary bank during a wire transfer

The most common scenario is the sending bank freezing the transfer before it completes. In that case, the money never leaves your account - it's just unavailable.

What documents you need to provide

Banks ask for different documents depending on the amount and the specifics of your situation. Prepare these in advance even if the bank hasn't asked for them yet.

1. Proof of Transfer Origin

• A statement from your bank account showing the debit attempt
• The exchange's deposit instruction (the screen showing the bank details and reference code you were told to use)
• An email from the exchange confirming they received a pending deposit (if applicable)

2. Proof of Purpose

• Your exchange account statement or transaction history showing the deposit is expected and matches the amount
• A letter from the exchange on their letterhead confirming the deposit is for cryptocurrency purchase (most major exchanges provide this on request within 1-3 business days)

3. Proof of Source of Funds for the Money You Sent

This is what the bank really wants: evidence that the money in your account came from a legitimate source. What counts as legitimate depends on your situation.

For salary earners: - Recent payslips (last 2-3 months) - Employment contract or confirmation letter from employer - Bank statements showing salary credits

For self-employed or freelancers: - Recent tax returns or tax assessment notices - Business bank statements showing client payments - Invoices and receipts for work performed - Client contracts

For savings or investments: - Bank statements showing accumulation over time - Investment account statements - Documents showing sale of assets (property, stocks, crypto from other wallets)

For gifts or loans: - A signed gift letter from the person who gave you the money - Their bank statement showing the transfer to you - A signed loan agreement if it's a loan

For crypto origin funds (money that came from selling crypto on another exchange): - That other exchange's transaction history showing the withdrawal to your bank - Your bank statement showing the credit from that exchange - A statement from the other exchange confirming your account ownership

4. Proof of Identity

• A copy of your government-issued ID (passport, driver's license, national ID card)
• A recent utility bill or bank statement showing your current address (if the bank requests it)

How to submit your documents

1. Contact the bank immediately. Call the number on the freeze notice or your bank card. Do not wait for the bank to contact you - they might not.

2. Ask exactly what they need. The bank's compliance team will tell you which specific documents they require. Ask for a case reference number and the name of the person handling your case.

3. Send documents securely. Upload them through the bank's secure portal if they offer one, or use the secure message function in your online banking. Do not email documents unless the bank explicitly says to.

4. Keep copies of everything. Save your submissions, the bank's acknowledgment, and any correspondence.

How long it takes

Processing times vary widely. For straightforward cases with clear documentation, banks often release the funds within 3-10 business days. Complicated cases where the source of funds is hard to document - such as cash savings accumulated over years without bank records - can take several weeks or longer.

What to Do If the Bank Still Refuses

If the bank does not release the funds after you submit everything they ask for:

• Escalate to the bank's complaint department. Most banks have a formal complaints process with a resolution timeline (often 15 business days).
• Contact the Financial Ombudsman Service in your country. In the US, that's the Consumer Financial Protection Bureau (CFPB); in the UK, the Financial Ombudsman Service; in the EU, your national financial ombudsman.
• Contact the exchange's support to see if they can help. Some exchanges have compliance teams that can communicate directly with your bank if you authorize it.

How to Avoid This in the Future

• Keep bank statements showing how you've accumulated your savings over time
• Use the same bank account consistently for exchange deposits rather than switching accounts
• Make deposits in amounts and at frequencies that match your normal banking pattern
• If you must make a large deposit, call your bank in advance to inform them

The key is preparation. Having clear documentation ready before you make a deposit is the only reliable way to shorten the time your money stays frozen.
