Q: Why does my bank in Cambodia ask for source of funds when I deposit a large amount?

Cambodia’s AML/CFT Law requires all NBC-licensed banks to conduct Enhanced Due Diligence on customers making large or unusual transactions. This includes documenting where significant funds originate. The requirement applies to everyone regardless of nationality or account history. Banks that fail to conduct this due diligence face serious regulatory penalties from the NBC and CAFIU. It is not personal — it is a legal compliance obligation.

Q: What is KYC and why do I have to provide it to open a bank account in Cambodia?

KYC stands for Know Your Customer — the mandatory identity verification process required by Cambodia’s AML/CFT Law for all bank account holders. Banks must verify who you are before allowing you to open an account. For Cambodians this means National ID and proof of address. For foreigners it means passport, valid visa, and proof of Cambodian address. KYC is not a discretionary bank policy — it is a legal requirement that applies across all NBC-licensed institutions.

Q: What amount triggers AML checks at Cambodian banks?

While the exact thresholds vary by bank, cash transactions of $10,000 or above in a single transaction generally trigger mandatory reporting requirements at Cambodian banks. Cumulative transactions that suggest structuring — multiple deposits just below $10,000 on consecutive days — also trigger scrutiny. Banks also monitor for behavioural patterns inconsistent with a customer’s stated occupation or business profile, regardless of individual transaction amounts.

Q: What is a Suspicious Activity Report (SAR) and will I know if one is filed about me?

A Suspicious Activity Report is a confidential report filed by a bank with Cambodia’s Financial Intelligence Unit (CAFIU) when a transaction or pattern raises AML concerns. By law, banks are prohibited from informing a customer if a SAR has been filed — this is called the “tipping off” prohibition, and breaching it is itself a criminal offence. The existence of a SAR does not mean you are guilty of anything — it means a transaction warranted reporting. CAFIU decides whether further investigation is warranted.

Q: Can a bank in Cambodia freeze my account for AML reasons?

Banks can place a temporary hold on specific transactions pending documentation review under AML obligations. A full account freeze — where you cannot access any funds — generally requires a court order or NBC/CAFIU instruction for law enforcement purposes. If your bank has frozen your account without explanation, contact the bank’s compliance team first, then escalate to the NBC at nbc.org.kh if the bank cannot provide a lawful basis for the freeze.

Q: I’m a returning EPS worker with Korean savings. What source of funds documents does ABA Bank need?

For large deposits from Korea EPS savings, ABA Bank and other Cambodian commercial banks typically accept: your EPS contract showing the term and employer, Korean bank statements showing salary deposits over the contract period, and the bank wire confirmation for the transfer to Cambodia. Preparing these documents in advance before making your large deposit will significantly speed up the compliance process and reduce the chance of any hold on your funds.

Q: Does Cambodia’s AML framework affect cryptocurrency transactions?

Yes. The NBC has specifically prohibited NBC-licensed banks from facilitating cryptocurrency transactions, partly for AML reasons — cryptocurrency is difficult to trace and has been used for money laundering globally. Cambodian banks that detect cryptocurrency-related deposits or transactions may file SARs and restrict the account. This is separate from Cambodia’s broader cryptocurrency legal status, which remains unclear in domestic law.

Q: What is CAFIU and how does it relate to my bank?

CAFIU is the Cambodia Financial Intelligence Unit — the government body responsible for receiving, analysing, and acting on Suspicious Activity Reports from financial institutions. CAFIU operates under the Council for the Development of Cambodia and coordinates with the National Police and international financial intelligence networks. If a bank files a SAR about a transaction on your account, CAFIU reviews it and determines whether to initiate a formal investigation.

Q: Can I be refused a bank account in Cambodia for AML reasons?

Yes. Banks have the right to refuse account opening or close existing accounts if a customer cannot satisfy KYC requirements or if the bank determines the customer relationship poses unacceptable AML risk. This is rare for ordinary customers who can provide standard ID and a clear source of funds. It is more common for customers from certain high-risk jurisdictions, those with complex or unclear financial activity, or those who have previously been subject to regulatory action in other countries.

Q: Is Cambodia’s banking system considered safe from a money laundering perspective?

Cambodia has made significant progress in strengthening its AML framework since 2019, implementing NBC Prakas that substantially tighten bank compliance requirements. The country has been working with FATF to address historical deficiencies. For ordinary legitimate bank customers, Cambodia’s tier-1 commercial banks — ABA Bank, ACLEDA Bank, Canadia Bank — operate to NBC-mandated AML standards and are considered sound within the regional context. The AML framework, while imperfect, provides meaningful protection against the financial system being used for criminal purposes.
