What Is the KYC/AML Process for Crypto Bros Like at a Swiss Private Bank?
A Swiss private bank runs its KYC and AML checks before it opens anything. Here is the five-stage sequence, the evidence required, and realistic timelines.

Summary
| Stage of the Swiss private bank KYC process | What the bank must establish | Typical duration once documents are complete |
|---|---|---|
| Eligibility review before onboarding | Whether the profile fits the bank's risk appetite at all | 2 to 5 business days |
| Identification of the client and the beneficial owner | Who you are and who ultimately owns the assets | 3 to 10 business days |
| Source of funds and source of wealth review | Where this transfer comes from and how the wealth was built | 5 to 15 business days |
| Risk classification and deeper checks | Whether standard due diligence is enough | 10 to 30 business days if deeper checks apply |
| Compliance decision and account opening | Whether the bank accepts the relationship | 5 to 10 business days |
A Swiss private bank runs its know your customer (KYC) and anti-money laundering (AML) checks before it opens anything, not after. A Swiss bank account exists only once the compliance file has been accepted.
The process follows five stages in Switzerland, from the first eligibility review through customer due diligence to the periodic review that continues for as long as the relationship lasts. Files involving crypto-origin wealth sit in the same sequence, but they spend longer at the risk assessment stage.
Why the Bank Reviews Me Before It Opens Anything
A Swiss private bank decides whether it wants the relationship before you complete a single account form. Compliance sits at the front of the process, not at the end, and a file that fails the first review never reaches an account manager. This is the part of KYC that clients rarely see, and it is where most applications for a Swiss bank account end.
This ordering is a legal obligation rather than a commercial preference. Swiss banks operate under the Anti-Money Laundering Act (AMLA) and its ordinances, alongside the Agreement on the Swiss banks' code of conduct with regard to the exercise of due diligence, published by the Swiss Bankers Association. Known as the CDB, it has been in force since 1977 in its successive versions, the current one being CDB 20.
Who looks at the profile first
- A compliance analyst, who runs sanctions screening and adverse media checks before any commercial discussion
- A relationship manager, who assesses whether the assets and the mandate match what the bank actually does
- For anything unusual in origin or structure, a compliance officer with authority to escalate the file
A high net worth individual is not exempt from any of this, rather larger scrutiny is applied especially when the origin of funds are from cryptocurrencies. A larger portfolio widens the range of questions rather than shortening the procedures, and the risk profile assigned at this stage governs everything that follows. The same is true for an ultra high net worth family office opening a Swiss bank account through a holding structure.
Why files are refused without explanation
Swiss banks rarely state the reason for a refusal, because doing so may itself breach reporting obligations. A rejection is not a verdict on the legality of your assets. It usually reflects that the bank concluded it could not evidence the origin of the wealth to its own supervisor at an acceptable cost.
Step 1: Who Am I, and Who Really Owns the Money?
The bank must establish two separate identities: the contracting partner who signs, and the beneficial owner who ultimately controls the assets. Where these are the same person, identification is short. Where a company, trust or foundation sits in between, the bank traces beneficial ownership through the structure down to the natural persons behind it.
This is the specific contribution of the CDB framework in Switzerland. Since 1977, Swiss banks have been required to identify the contracting partner and establish the ultimate beneficial owner (UBO), using a written declaration signed by the client. Corporate applicants go through the same exercise on the entity itself, which is where know your business (KYB) checks apply.
What the bank collects at this stage
- A certified copy of a passport or national identity document
- Proof of residential address, usually recent and issued by a third party
- A signed declaration identifying the ultimate beneficial owner, since beneficial ownership must be established in writing
- For a corporate structure, incorporation documents and the ownership chain up to the natural persons
- Tax residence details, which feed the automatic exchange of information under the Common Reporting Standard (CRS), and FATCA reporting for US persons
- Message signatures or “Satoshi tests” performed on the client’s past and current wallets to prove ownership
Nothing at this stage concerns the origin of the money. Identification answers who, and only who. The harder question comes next, and it is the one where the documents banks ask for when you cash out crypto become decisive.
Step 2: Where Did This Transfer Come From, and How Was the Wealth Built?
The bank asks two distinct questions here, and confusing them is the most common reason a file stalls. Source of funds concerns one specific transaction: where the money arriving today came from. Source of wealth concerns the whole picture: how the fortune was accumulated over a career or a lifetime. Both must be evidenced, and evidence of one is never accepted as evidence of the other.
A client can document a wire transfer perfectly and still fail on source of wealth, because the bank cannot reconstruct how the underlying capital was built. The distinction between source of wealth and source of funds is worth understanding before the first meeting rather than during it.
Typically for cryptocurrency origin fund clients, it is required to submit read-only API keys of exchanges where the client traded, current and past wallet addresses and a brief overview of the flow of funds since the client first started purchasing cryptocurrencies.
What satisfies each question
| Question asked by the Swiss private bank | Scope of the answer | Evidence commonly accepted |
|---|---|---|
| Source of funds | One transaction, one origin | Sale contract, exchange statement, settlement confirmation |
| Source of wealth | The full accumulation history | Employment history, company sale documents, inheritance deeds, tax filings |
Why crypto-origin wealth takes longer here
Digital assets rarely come with the paper trail a bank is used to reading. Early positions may predate any exchange account, wallets change over the years, and platforms disappear. Analytics providers such as Chainalysis, Elliptic and TRM Labs are used to trace the on-chain history, and the resulting report becomes part of the file. Preparing that evidence is the work of proving crypto source of funds to a private bank, and when it is done before the bank is approached it drastically improves the chances of being accepted as a client in a Swiss private bank.
Step 3: What Makes a File Take Longer Than Usual?
Every file goes through a risk assessment, and the resulting risk profile decides how deep the checks go. Customer due diligence (CDD) covers most relationships. Enhanced due diligence (EDD) applies where the bank identifies a factor that requires more evidence, and it is where timelines stretch from days into weeks.
What makes a bank ask for more than the standard file
- Politically exposed person (PEP) status, whether held by the client or by a close associate
- Residence or asset location in a jurisdiction rated higher risk by the FATF
- Wealth originating from digital assets, particularly where it predates regulated exchanges
- Complex holding structures across several jurisdictions
- Amounts that are large relative to the documented income history
None of these makes a relationship impossible. They change the standard of proof, not the answer. There is no legal ceiling on the amount a Swiss private bank may accept, only an obligation to evidence where it came from.
Step 4: Who Decides, and How Long Does It Take?
The decision belongs to compliance, not to the relationship manager who met you. On files involving higher risk factors, an acceptance committee signs off, and its decision is documented so that it can be defended to FINMA years later.
Once a file is complete, a decision commonly takes 5 to 10 business days. The variable is almost never the bank's speed. It is how long the client takes to assemble evidence the bank can rely on, which is why a prepared file and an improvised one produce very different timelines. Where funds are already in transit and questions arise, an account may be frozen for 30 to 90 days while the bank completes its review. That is why it is always best to get a confidential compliance review then a KYC/AML report done with Altcoinomy and get your documentation accepted before you cash-out your cryptocurrencies.
What a regulated intermediary changes in the sequence
As a Swiss financial intermediary supervised by the VQF under AMLA, Altcoinomy carries out the compliance work before the bank sees the file, and carries the responsibility for it. The bank receives a documented file from a regulated counterparty rather than an individual case it must investigate alone, which reduces its own risk and increases acceptance. We are neither a bank, since we take no deposits, nor a standard OTC desk: those stop at fiat conversion, and we pick up where they leave off. Our intake review runs 5 to 15 business days. Confidential Compliance Reviews allow you to have the AML side of your case to be reviewed before you share your identity.
Step 5: What Happens After the Account Is Open?
KYC does not end at account opening. Swiss banks monitor relationships continuously and refresh customer due diligence at intervals set by the risk profile, which means questions can return years into a relationship. Confidentiality protects that information from third parties, but it never removes the bank's own obligation to keep the file current.
What triggers a fresh round of questions
- A periodic review, scheduled more frequently for higher risk files
- A transaction that does not fit the profile agreed at onboarding
- A change in circumstances, such as a new residence, a new mandate or a new political function
- An incoming transfer from a counterparty the bank cannot identify
Where a bank forms a suspicion it cannot resolve, it reports to the Money Laundering Reporting Office Switzerland (MROS) rather than to the client. Assets may be blocked during that process. Keeping documentation current is therefore not administrative housekeeping, it is what keeps a relationship stable, and it applies equally when opening a Swiss private bank account with crypto-origin wealth.
Frequently Asked Questions
Does Switzerland really apply KYC rules to private banking clients?
Yes, and it applies them earlier than most jurisdictions. Swiss banks have identified beneficial owners under the CDB since 1977, well before international standards required it. Banking confidentiality protects client data from third parties, it does not exempt anyone from due diligence.
How long does the KYC process take at a Swiss private bank?
A complete file is commonly decided within 5 to 10 business days. Where enhanced due diligence applies, the review runs 10 to 30 business days. The variable is document preparation on the client side, not processing speed at the bank.
Is it legal for a US citizen to hold a Swiss bank account?
Yes, provided the account is declared. US persons are reportable under FATCA, and the account must appear in the relevant US filings. Some Swiss banks limit US client onboarding for their own reasons, which is a commercial choice rather than a legal restriction. This is not tax advice.
What is the minimum amount to start the process?
Swiss private banks set their own entry levels and publish few of them, so the threshold varies case by case. On our side, we handle account openings from USD 1,000,000 upwards, in CHF, EUR, USD, GBP, AED and ILS, and the compliance requirements are identical at every level. The seeding of the account can be done in tranches, typically new clients start with the minimum amount which is USD 25,000 equivalent to ensure the money lands in their account and they test that their debit/credit cards as well as their account works as they intended.
Can the bank reopen my file once the account is open?
Yes. Monitoring is continuous and files are refreshed at intervals set by the risk classification. A transaction outside the agreed profile, a change of residence or a new political function may all trigger a fresh review, sometimes years into the relationship.
Preparing to approach a Swiss private bank?
We assemble the compliance file before the bank sees it, as a regulated Swiss intermediary supervised by the VQF, so the origin of your assets is documented to the standard a private bank applies.
