# Source of funds vs source of wealth: why banks ask and how to answer

Source: https://wealthscout.app/updates/why-banks-ask-source-of-wealth

A source of funds check asks how money for a specific transaction was obtained. A source of wealth check asks how your broader asset position was accumulated over time. Financial regulators require institutions to request this evidence as part of customer due diligence and global anti-money laundering controls.

## Takeaways

- Banks use algorithm tripwires to ask source of funds and source of wealth questions as part of global financial crime controls.
- The 'prove it' panic happens when you have to dig through years of scattered files to satisfy an underwriter.
- A good record trail attaches the historical context directly to the asset, so you are always ready for regulatory checks.

**Scope.** The evidence requested depends on the institution, the transaction size, and their risk algorithms. Always ask the requesting compliance officer exactly what they need, and use secure channels for sensitive documents.
