Your Bank Called About Suspicious Activity

Why is your bank calling you?

Malaysian banks must watch account activity by law. Under AMLA Section 14, they must report suspicious transactions to Bank Negara Malaysia. ^[f1] When their system flags something on your account, the bank may phone you first.

The call does not mean you are in trouble. The bank needs to check one or more transactions before deciding what to do. How you answer can affect what happens next.

What the bank can and cannot do

During its review, the bank can restrict account activity under its own account terms and its duties under AMLA and Bank Negara’s AML/CFT rules. ^[f4] The compliance team can do this on its own while it reviews flagged transactions. ^[f2]

So the bank can limit your access even before any police or AMLA order exists. This is the bank’s own measure, and it works differently from a formal freeze.

You can ask the bank in writing which authority or order is behind the freeze. ^[f3] The bank may not be allowed to tell you about any suspicious transaction report. If it is only the bank’s own hold, the bank should tell you that too.

How to handle the call

Stay calm and cooperate. The officer is doing a job the law requires. Your answers can decide whether the matter ends with this call or goes further.

Check the caller first. A real bank officer gives a name and department. They never ask for your PIN, TAC, OTP or online banking password. If anything feels wrong, hang up and call the bank on the number on your card or its official website.

Answer questions about the flagged transactions. If you made the transaction, say so and explain what it was for. If you did not, say that clearly. Be honest and specific.

Ask your own questions. Ask which transaction led to the call: the date, the amount and who received it. Write down the officer’s name, the date of the call and everything they tell you.

What the bank may not be able to tell you

There are limits on what the bank can share. If an authority has told the bank not to reveal investigation details, the bank must obey. ^[f5] That is a legal duty on the bank, not a choice.

If the bank says it cannot share something, that tells you something too. An outside authority may already be involved, which changes your next steps.

When the bank cannot say more, a lawyer who handles frozen account cases may be able to work out the likely authority and process from the details you do have.

Is this call a scam?

Scammers sometimes pretend to be bank officers to steal your details.

A real bank call asks you to confirm or deny specific transactions. The officer gives a full name and department. They do not ask for passwords, TACs or OTPs, and do not push you to move money to a “safe account”.

A scam call rushes you by saying your money is at risk. The caller asks for your banking details. They may pass you to a fake “police officer” or “BNM officer” and insist you act now or lose your money.

If you suspect a scam, hang up at once and call the bank on the number on your card. You can also use the PDRM Semak Mule portal to see whether your account has really been flagged. Read about understanding account freezes to know what a real freeze looks like.

What to do after the call

Write everything down. Note the officer’s name, the date and time, which transactions were discussed and what the bank said it would do next. This record protects you.

Collect supporting documents. Gather papers that explain the transaction the bank asked about: invoices, contracts, payslips or the other party’s transfer receipts. Our guide on preparing your evidence has a full list.

Do not move money around. Moving funds to another account after the call can look like you are hiding something. Leave your accounts as they are.

Check your other accounts. If you bank elsewhere too, check that those accounts still work. A freeze at one bank does not automatically reach another, but several banks may flag the same pattern.

When the call leads to a freeze

Sometimes a restriction or freeze follows the call, either during it or in the days after.

If the bank says your account is restricted, ask whether it is the bank’s own hold or an order from an outside authority. A bank hold can be lifted by giving the bank the documents it asks for. A freeze ordered by an authority follows a different legal process.

If your account is frozen, our first-hour action guide covers what to do straight away. The what to do now page takes you through the wider process.

When should you get legal help?

Not every call needs a lawyer. If the bank asked about a transaction, you explained it and your account still works, the matter may be over.

Speak to a lawyer if the bank says your account is restricted or frozen. Also get advice if the bank mentions an authority, cannot explain the restriction, or you are asked to go to a police station.

A qualified lawyer can find out which authority is involved, explain your rights and prepare the papers needed to sort it out.

How to avoid future flags

The call is a good reason to look at your own banking habits. Large sums from unfamiliar sources, money sent back and forth often, or activity that does not match your income can all trigger a flag.

If you run a business, keep personal and business money in separate accounts. Mixing them in a personal account can be a reason for these calls.

If you often receive money from overseas, keep records of what each transfer was for and where it came from. Remittance slips, invoices and contracts let you answer the bank’s questions quickly.
