Short definition (lead paragraph) Source of funds refers to the origin of the specific money or assets used in a given transaction or business relationship. It focuses on the immediate funding source rather than on a person’s entire financial background. Source-of-funds checks are common in AML, fiat on-ramping, large transfers and card or credit funding reviews.
Key points / Quick facts
- It concerns a specific pool of money used now.
- It is narrower than source of wealth.
- Evidence often includes bank statements, payslips and sale documents.
- It is important for large deposits, on-ramps and suspicious patterns.
- In crypto, it may involve both fiat and on-chain tracing.
What is source of funds?
Source of funds answers a short-term compliance question: where did this money come from? That question matters whenever a provider needs to know whether the funds entering a product or transaction are legitimate. The focus is not on the customer’s whole life story but on the specific value entering the system.
How source of funds works
The provider asks for documentation or evidence linking the funds to a legitimate event or stream of income. That may involve salary records, sale proceeds, dividend statements, loan documentation or on-chain transaction history. The goal is to ensure that the immediate funds being used make sense for the customer’s profile.
Why source of funds matters
Source-of-funds analysis helps prevent money laundering and reduces the risk of accepting illicit or suspicious assets. It is especially important in crypto because value can move rapidly and may arrive from opaque or high-risk sources. For card and credit products, it also matters when large balances or top-ups support higher usage or borrowing.
Types / examples
Examples include salary-funded deposits, proceeds from a property sale, loan-funded account loading and traceable crypto transfers into a regulated platform. Each case requires evidence suited to the specific funding event.
