Source-of-funds proof for Hong Kong banks: what the request means and what satisfies it

Current to 26 August 2026 · updates land in the changelog.

The 資金來源證明 request is where reviews are won or lost, because it is the one category that wants a story, not just documents. The bank is matching money in the account to an origin it can defend to its own examiners.

Two questions hiding in one phrase

Source of funds: where did this money immediately come from — the salary, the sale, the loan, the customer payment. Source of wealth: how did you come to have money at all — years of income, a business built, an inheritance. Requests often blend them; answers shouldn't. Label which question each document answers and the file reads as organised rather than defensive.

The documents that carry weight

• Payslips (糧單) and employment contracts — salary flows.
• Bank statements showing the path — the transfer chain from origin account to this one.
• Financial statements — business income; audited beats management, but genuine management accounts beat nothing.
• Sale-and-purchase agreements, completion statements — asset disposals.
• Tax records — corroboration across years.

The connective tissue matters as much as the documents: a one-page chronology tying each inflow to its evidence turns a folder into an answer.

Gaps: handle honestly, never cosmetically

Old money, cash-era businesses and cross-border histories produce genuine gaps. The survivable approach is stating the gap and corroborating around it (tax records, older statements, contemporaneous documents). The unsurvivable approach is papering it — Hong Kong institutions apply zero tolerance to questionable or forged documents, and a discovered fabrication converts a document problem into a legal one. Genuine records only, presented in their best order: that is the entire method.

Context that explains the season

Source-of-funds pressure is systemic right now — banks and brokers are re-verifying under regulatory attention, and mule-account crackdowns (147 arrests in one August 2026 operation) keep detection thresholds tight. A clean file answers faster in a noisy season; that is the practical case for assembling it before the letter arrives.

Quick answers

What is the difference between source of funds and source of wealth?

Source of funds: the immediate origin of the specific money (this salary, this sale). Source of wealth: how you accumulated wealth over time. Requests blend them; strong answers separate and label them.

What if I can't fully document where old money came from?

State the gap honestly and corroborate around it with tax records, older statements and contemporaneous documents. Never fabricate — regulators apply zero tolerance to questionable documents, and honest gaps are routinely survivable.

General information and document templates only — not legal advice. Organise genuine records only: never alter, backdate or fabricate a document — regulators apply zero tolerance and an honest gap explained is survivable where a fabricated paper is not. Anything involving police, the JFIU, a Letter of No Consent, restraint orders, personal suspicion or a sanctions nexus belongs with counsel, not templates.
