Source of Wealth, Source of Funds: Knowing the Difference

Source of wealth and source of funds are not the same question. Confusing them, or treating one as a substitute for the other, is one of the most common practical failings that turns up in FSA inspections and thematic reviews.

Where did this person’s wealth come from? And where did this particular money come from?

Source of wealth answers the first. Source of funds answers the second. Both matter, neither is optional, and the answer to one does not answer the other.

What source of wealth means

Source of wealth is the broader picture; a financial biography. It is the story of how a person accumulated the assets they have: their career, their business interests, an inheritance, a property portfolio built over decades, a successful exit from a company they founded. It answers the question of whether the overall wealth profile makes sense given what you know about the person.

A client who presents as a retired teacher with assets of several million pounds has a source of wealth question to answer. A client whose declared income is modest but who is purchasing high-value property through a corporate structure has a source of wealth question to answer. The exercise is about plausibility. Does the wealth fit the person?

One important practical point: source of wealth carries no legislative requirement at lower and medium risk levels. It is genuinely valuable best practice, but the Code does not impose a mandatory obligation to establish it unless you are dealing with a foreign PEP, a higher risk domestic PEP, or a higher risk rated relationship more generally. That said, treating it as optional at lower risk levels and ignoring it entirely are not the same thing. A basic narrative of how a client’s wealth arose is sensible for any relationship, and where the nature or size of a transaction is clearly outside what you understand to be a client’s normal capabilities, that should prompt further enquiry regardless of risk rating.

Source of wealth gathering should not become an exhaustive fishing exercise. The documents and information you request should be appropriate, proportionate and sufficient to address the specific wealth question in front of you, not a comprehensive audit of a client’s entire financial history.

What source of funds means

Source of funds is narrower and more transactional. It relates to the immediate funding of the relationship or transaction: both the activity that generated the funds and the means through which they will be transferred.

That two-part definition matters. It is not enough to know that a client runs a profitable business. You need to understand how the funds being used in this transaction were generated, and how they are moving. Which account are they coming from? Whose name is on it? Is there an intermediary in the chain, and if so, why?

Unlike source of wealth, source of funds requires reasonable measures to establish it for every risk level. It applies to every client, every transaction. Importantly, the FSA is clear that the obligation applies to all relevant persons regardless of whether the funds actually pass through their hands. The nature of your services does not remove the requirement. If you are involved in a transaction, the question of where the money comes from is your question to ask, whether or not you ever see the money.

A clean source of wealth narrative does not automatically mean clean source of funds. The two travel together but they are separate journeys.

Third party funds

A specific scenario worth flagging: funds that arrive from someone other than your client. This happens more often than people expect, whether it is a family member settling fees, a connected company transferring funds, or a third party funder with no obvious connection to the matter.

Where funds come from a third party, the reasons need to be understood and recorded. Depending on the risk profile of the transaction, you may also need to verify the identity of the account holder and satisfy yourself as to the provenance of those funds. The fact that your client relationship is with someone else does not remove your obligation to ask questions about the money actually moving through the transaction.

The calibration question

One of the most common points of uncertainty in practice is not whether to investigate, but how deeply.

The risk rating must drive the depth of enquiry.

For lower risk matters, it is generally reasonable to rely on the information a client provides without seeking independent verification, provided you have recorded what you were told and why you found it credible.

For medium risk matters, corroborating documentation is expected: something that supports the client’s narrative, whether provided by them or sourced independently.

For higher risk matters, foreign PEPs and higher risk domestic PEPs, verification should be more substantive and independent. Documentary evidence should be obtained and retained on file, drawn from multiple sources where possible, with a clear record of what was asked, what was received and what conclusions were reached.

Where firms go wrong

The most common mistake is treating source of wealth as sufficient. A client with a well-documented, entirely plausible wealth profile can still present source of funds concerns if the money moving through a transaction does not match what you would expect. Funds arriving from an unexpected jurisdiction, through an unfamiliar entity, or via a route that does not align with the client’s stated business activity should prompt questions regardless of how comfortable you are with the broader wealth picture.

The second mistake is superficiality. A file note that says “client is a director of several companies and has substantial business interests” is not source of wealth documentation. It is a description. Documentation means understanding what those companies do, what the client’s role and financial interest in them is, and whether the level of wealth is consistent with that over a credible timeframe.

The third is inconsistency: applying scrutiny to some clients but not others based on instinct rather than a documented, risk-based framework. Or applying only half of the source of wealth test; identifying the bank account funds will flow from but not interrogating the activities that generated the funds.
The standard that applies

An undocumented source of funds enquiry is no enquiry at all when the regulator is reviewing your file. Good practice means asking the question for every material transaction, not just at onboarding. Circumstances change, and periodic review and ongoing monitoring exist precisely to catch the kind of drift that onboarding checks cannot anticipate.

The two questions are different, but the standard they are held to is the same: you need to be able to show that you asked, that you received a credible answer proportionate to the risk in front of you, and that you documented both.
