AEON Bank Reverses RM1 Billion Credit Linked to Merdeka Reward Campaign Glitch
An AEON Bank customer opened his app on 14 October to find more than RM1 billion sitting in his account, labelled as a cash reward from the digital bank’s Merdeka and Malaysia Day campaign. The bank reversed the entry the same day and says no accounts or customer information were compromised. The episode is harmless for the customer, but it is a useful reminder of how much rides on the back-office systems behind Malaysia’s new digital banks.
Key facts
- A credit of RM1,000,315,879 appeared in the customer’s AEON Bank account at about 10.36am on 14 October 2026, tagged as a “Bank adjustment”.
- The entry was described as “Cash Reward – Merdeka / Malaysia Day 2026 Campaign (Cycle 6)”, the final round of a promotion that ran from 17 August to 27 September.
- The whole campaign budget was only RM12,834, shared by 414 winners who each received RM31 for spending at least RM15 through DuitNow QR.
- The customer reported the credit instead of spending it; AEON Bank temporarily restricted the account, reversed the transaction the same day and left his original balance untouched.
- AEON Bank said a promotion-related issue made some balances display incorrectly. It has not disclosed the technical cause or how many customers were affected.
What happened
The customer shared a screenshot of the transaction on Threads, and it spread quickly across Malaysian social media and news sites. He said he had not knowingly joined any promotion or made a purchase that would explain the money. After checking his app, he contacted the bank, which confirmed the credit was a mistake and removed it. In a follow-up post he said the bank had offered him a reward for flagging the problem quickly, with details still to come.
The size of the error is what made it a story. The amount credited was roughly 78,000 times the entire reward pool for the six-week campaign, which paid 69 winners a week. That points to a fault in how the reward was calculated or posted, rather than a deliberate payout. In a statement on LinkedIn, AEON Bank said it had promptly resolved the issue and stressed that no accounts or information were compromised.
AEON Bank (M) Berhad is Malaysia’s first Islamic digital bank, meaning its products follow Shariah (Islamic law) principles. It received its licence from Bank Negara Malaysia (BNM), the central bank, and the Minister of Finance on 8 January 2024, and launched to the public on 26 May 2024. AEON Credit Service (M) Berhad holds 50% of the bank.
What it means for Malaysians
- For customers: nothing was lost, and the bank says no data was exposed. But the case shows why it pays to check your transaction history, not just your balance. If money you do not recognise appears, the sensible move is the one this customer made: contact the bank and do not spend it, because erroneous credits are normally reversed.
- For digital banks: app-only banks win customers with rewards, cashback and campaigns. Every promotion is a piece of software that moves real money, so the controls that cap payouts and catch abnormal amounts matter as much as the marketing. An unexplained billion-ringgit credit is the kind of event that can dent trust in a young brand.
- For merchants and SMEs: many campaigns, like this one, are designed to push more spending through DuitNow QR, Malaysia’s national QR payment standard. Merchants benefit from that traffic, but they also rely on banks’ systems working smoothly when rewards and refunds are processed at scale.
Mistaken credits are not new in banking, and this one was caught within hours. The quicker the detection and reversal, the smaller the damage, and here the speed of the fix was helped by a customer who reported it himself.
What to watch
- Whether AEON Bank explains the technical cause and confirms how many accounts showed incorrect balances.
- Any changes digital banks make to how campaign rewards are tested and capped before they are paid out.
- How customers respond to future AEON Bank promotions, and whether the bank’s quick fix helps protect its reputation.
