Bank account frozen or closed?
Reasons, your rights and what to do
Suddenly can’t transfer or withdraw money, or got a letter saying the bank will close your account? This page explains common reasons, the rules banks should follow, and how to follow up.
Last updated: 2026-10-16
Quick answer: do these 3 things now
- 1. Ask the bank in writing: request an explanation where permitted by law, and what information you need to provide.
- 2. Provide information quickly: many restrictions relate to customer due diligence, such as source of funds, income or address proof.
- 3. If police are involved: get legal advice promptly, and don’t try to move money out of the account yourself.

Account frozen or closed: 3 common reasons
| Reason | What it means | What you can do |
|---|---|---|
| Customer due diligence (CDD) review | The HKMA says banks must regularly review and update existing customers’ information; if you can’t provide what’s required, the bank may restrict or close the account. | Watch for bank letters and respond quickly; if you have difficulty, call the bank to discuss. |
| Suspected suspicious transactions | Banks monitor accounts on an ongoing basis and may restrict or close accounts linked to suspected suspicious transactions. | Explain the transactions in writing with supporting documents, such as invoices, contracts or source of funds. |
| Police or law enforcement investigation | After a bank files a suspicious transaction report with the JFIU, the authorities may issue a letter of no consent, and the bank may stop operating the account. | Get legal advice quickly; you can ask the bank about releasing funds for necessary expenses. |

What rules must banks follow? Your rights
- At least 30 days’ notice before closing: government information says that under the Code of Banking Practice, banks should give at least 30 days’ notice before closing an account, except in exceptional circumstances, and longer where possible. (The government information doesn’t list what counts as exceptional circumstances. If an account is linked to suspected illegal activity or suspicious transactions, the bank may treat it as exceptional – so not getting 30 days’ notice doesn’t necessarily mean the bank broke the rules.)
- Explain reasons where appropriate: banks should explain reasons where appropriate and permitted by law, and closure letters should be clear to customers. But if suspicious transactions or a police investigation are involved, the bank is likely to give no specific reason – only citing its terms or a “commercial decision” – so be prepared for that when you write.
- Fair treatment: the HKMA expects banks not to take a one-size-fits-all approach, to apply due diligence proportionately to each customer’s background and risk, and to communicate adequately.
Why won’t the bank tell me the reason?
If the bank has filed a suspicious transaction report, the law prohibits “tipping off”, so it may not be able to give details. According to a law firm’s analysis of the Court of Final Appeal case, a police letter of no consent is not itself a legal freezing order – the bank decides to freeze when its suspicion isn’t dispelled, and it can resume operating the account if, after due diligence, it is satisfied the suspicion is unfounded.

4 steps to deal with a frozen or closed account
- 1
Ask for the reason in writing
Use the letter template below and send it to the bank’s customer service or complaints team, asking for an explanation and what information you need to provide. Keep all letters and reference numbers.
- 2
Provide information to address concerns
Provide documents such as source of funds, income, transaction background or proof of address. A law firm notes that proactively engaging with the bank to address its concerns is key to lifting a suspension.
- 3
Arrange another account and essential payments
If you get a closure notice, move direct debits, salary payments and other arrangements during the notice period. While frozen, you can ask the bank about releasing funds for essential payments.
- 4
Complain and escalate
If you’re unhappy, complain formally to the bank first, then to the HKMA; the HKMA also has an account opening and maintenance email accountopening@hkma.gov.hk and hotline 2878 1133. If you have a clear money loss or compensation dispute, consider the Financial Dispute Resolution Centre (FDRC); note the FDRC handles money claims – it is not a way to make a bank unfreeze an account or reopen one. If a police investigation is involved, see a lawyer promptly.

How to lower the risk of a frozen account
- Reply quickly to bank letters asking you to update your information.
- Keep invoices, contracts and other proof for large or unusual transactions.
- Never lend or sell your account to anyone – the HKMA warns this can be a money laundering offence.
- If money arrives from a stranger, don’t move it yourself – let the bank handle it.

Account frozen or closed FAQs
How much notice must a bank give before closing my account?
According to government information, under the Code of Banking Practice banks should give at least 30 days’ notice before closing an account, except in exceptional circumstances, and a longer period where possible so customers can make other arrangements.
Must the bank tell me why my account was frozen or closed?
Not always. Government information says banks should explain the reasons where appropriate and permitted by law. If the bank has filed a suspicious transaction report with the Joint Financial Intelligence Unit (JFIU), it may be unable to give details because the law prohibits “tipping off”.
Does a police “letter of no consent” freeze my account?
According to a law firm’s analysis of the Court of Final Appeal case, the authorities’ letter of no consent is not itself a legal freezing order – it is the bank that decides to suspend the account when its suspicion isn’t dispelled. So engage with the bank, provide information, and get legal advice quickly.
Can I ask the bank to release some money for rent or salaries while frozen?
You can try. A law firm suggests negotiating with the bank to release funds for necessary payments such as salaries and operating expenses, but whether the bank agrees depends on the case.
Who can I complain to if I’m unhappy with the bank?
Complain formally to the bank first. You can then complain to the HKMA about the bank’s service or conduct; the HKMA also has an account opening and maintenance email, accountopening@hkma.gov.hk, and hotline 2878 1133. For a clear money loss or compensation dispute, consider the Financial Dispute Resolution Centre (FDRC) – but it handles money claims, not requests to unfreeze or reopen accounts.
