Background

Why Banks Ask About Crypto Origins

Banks are legally required under anti-money laundering regulations to clarify the origin of unusually large deposits. Crypto assets trigger inquiries particularly often.

01_AML_RULES

Anti-Money Laundering (AML)

Since the tightening of AML regulations, banks must actively inquire about suspicious transactions. Crypto deposits are considered a higher risk. The bank is required to document the origin of funds.

02_DAC8_REPORTING

DAC8 & Automatic Data Exchange

Starting in 2026, crypto platforms will automatically report transaction data to tax authorities (DAC8). Banks expect customers to be able to proactively prove their crypto activities.

03_ACCOUNT_RISK

Account Restriction Looming

Without complete proof of funds, the bank can restrict your account: block transfers, delay withdrawals, or in extreme cases close the account entirely.

Step by Step

How to Respond to a Bank Request

The right response to a bank letter determines whether your account gets unblocked. These steps are crucial:

1

Review the letter

What exactly is being requested? What is the deadline?

2

Gather documents

Exchange exports, wallet addresses, transaction history

3

Prepare documentation

Chronological, complete, understandable for bank staff

4

Submit on time

Respond completely, request a deadline extension if needed

The most common mistake: Only sending a tax report. Banks want to see the entire transaction history, not just a tax summary.

Checklist

Which Documents Do You Need?

A complete proof of funds consists of several building blocks. Depending on the complexity of your portfolio, you will need:

Fiat Origin

Bank statements proving the purchase of cryptocurrencies. Which account was used to transfer to which exchange?

Exchange Exports

Trade history from all exchanges used. CSV exports from Binance, Bitpanda, Kraken, etc.

Wallet Mapping

Overview of all your own wallet addresses with assignment to chains and purpose.

On-Chain Proof

For DeFi and wallet transfers: transaction hashes that prove movements between your own wallets.

Chronological Summary

Traceable presentation of the entire crypto journey: purchase, transfer, swap, sale.

Tax Documentation

Crypto tax report as supplementary evidence (not as standalone proof).

Common Mistakes

These Mistakes Most People Make with Bank Requests

1

Only sending the tax report

Banks don't want a tax summary. They want the transaction history. A tax report answers the wrong question.

2

Responding too late

Letting the deadline pass signals to the bank that something is wrong. It is better to request a deadline extension than not to respond at all.

3

Incomplete documentation

Missing wallets or time periods lead to follow-up questions. Every gap raises red flags.

4

Responding without professional help

For complex DeFi portfolios or multiple chains, professional documentation is often the faster and safer route.

Frequently Asked Questions

What We Get Asked Most

Yes. Banks are legally required under anti-money laundering regulations (AML) to restrict or freeze accounts when the source of funds is unclear. That is why a quick and complete response is important.
A tax report alone is usually not enough. Banks want a traceable documentation of the entire transaction history: where the cryptocurrencies came from, how they developed, and where they went.
DeFi transactions require special explanation for banks. On-chain data can ensure traceability. TX-Partner reconstructs DeFi histories and prepares them in a bank-compliant format.
It depends on the complexity of the portfolio. For exchange-only portfolios, documentation can be ready in a few days. For DeFi activity across multiple chains, expect 1-3 weeks for a complete preparation.
Missing the deadline can lead to account suspension or a report to the financial intelligence unit. If the deadline is tight, you should request an extension and start working on the documentation at the same time.
