Update: an AML and source-of-funds file for the Cayman Islands counterparty

Banks handling cross-border payments through Hong Kong are tightening their correspondent requirements. When the counterparty sits in the Cayman Islands, the AML and source-of-funds file has become a threshold condition – not a post-onboarding formality. Deals and payment channels stall at precisely this point.

An AML and source-of-funds file (a compliance dossier establishing the counterparty's identity, beneficial ownership and the legitimate origin of funds) is now the primary gating document for cross-border transactions involving a Cayman Islands entity routed through a Hong Kong bank or correspondent. The governing instrument in Hong Kong is the Anti-Money Laundering and Counter-Terrorist Financing Ordinance; in the Cayman Islands, the relevant anti-money laundering legislation and the Cayman Islands Monetary Authority's guidance set the parallel obligations. Both regimes apply simultaneously when the payment corridor crosses both jurisdictions.

This briefing identifies what is driving the current round of file requests, which principals are in scope, and the immediate action required to keep the channel open.

What Has Changed and Why It Matters Now

Correspondent banks clearing Hong Kong dollar and US dollar payments through Hong Kong have materially raised their enhanced due diligence (EDD – a deeper level of know-your-counterparty review applied to higher-risk relationships) thresholds for offshore counterparties. Cayman Islands entities – funds, SPVs, holding companies – attract EDD as a category.

Two structural features are driving the change. First, the FATF Mutual Evaluation cycle (the periodic peer review of a jurisdiction's AML and counter-terrorist financing controls) has placed renewed emphasis on beneficial ownership transparency and source of wealth documentation for offshore corporate vehicles. Cayman Islands entities are not a problem in themselves; they are a structuring tool that requires a documented compliance position. Second, Hong Kong banks are responding to their own regulators' expectations under the Anti-Money Laundering and Counter-Terrorist Financing Ordinance, which requires institutions to apply a risk-based approach and to hold adequate records of the customer and the transaction chain.

In our cross-border practice, we see file requests arriving without warning – often mid-transaction, when a payment instruction is queued and the bank's compliance team applies a hold. The correction is procedural, but the timing can be damaging.

Who Is Affected Across the Hong Kong – Cayman Islands Corridor

The trigger is structural, not sector-specific. Any principal with a Cayman Islands entity in the payment chain – whether as payer, payee, guarantor or interposed holding vehicle – will face this file request when the Hong Kong leg is engaged.

The affected population includes: fund managers routing capital calls or distributions through a Hong Kong correspondent; operating groups with a Cayman holdco above a Hong Kong subsidiary; joint-venture structures where one party is a Cayman SPV; and family offices using a Cayman Islands vehicle for investment or treasury activity. The common thread is a Hong Kong bank or payment intermediary applying the Anti-Money Laundering and Counter-Terrorist Financing Ordinance's customer due diligence rules to the offshore counterparty.

Counsel on our desk regularly see delays in this corridor. The pattern is consistent: the Cayman entity is legitimate, properly registered, and subject to Cayman AML obligations – but the file assembled for the Hong Kong bank is incomplete, out of date, or assembled without regard to what the receiving institution actually requires.

The Immediate Action

The compliance file for a Cayman Islands counterparty operating through a Hong Kong bank typically requires four components assembled in a form the bank can process.

First, corporate existence and good standing: a current certificate of good standing from the Cayman Islands General Registry, accompanied by the constitutional documents and the register of directors. Second, beneficial ownership: a chart of the ultimate beneficial owner or owners, verified to the standard required under both the Cayman AML regime and the Hong Kong bank's own policy – usually identification documents and proof of address for natural-person UBOs above the relevant threshold. Third, source of funds and source of wealth: a documented narrative explaining how the funds entering the transaction were generated, supported where possible by financial statements, investment records or subscription documentation. Fourth, purpose of the transaction and business relationship: a clear description of what the payment or relationship is for, which anchors the entire file in a plausible commercial context.

Where a payment is already held, the file should be submitted directly to the bank's compliance function, not through the relationship manager alone. The relationship manager is not the decision-maker on a compliance hold.
