Sumitomo Mitsui Banking Corporation experienced a significant system failure early on April 29, 2025, starting around 1:20 AM. This disruption has left ATMs at various branches and sub-branches, particularly in the Kansai region, inoperable. Additionally, customers using online banking services, specifically the "SMBC Direct" platform, have reported being unable to access their accounts.
The affected branches include approximately 50 locations across Hyogo and Osaka Prefectures. Among these, the digital branch known as the "Olive ASH Branch," part of the financial service "Olive," is also impacted. The bank has confirmed that internet banking services are not available for accounts linked to these branches.
In light of the inconvenience caused, Sumitomo Mitsui Banking Corporation issued a public apology: "We deeply apologize for the significant inconvenience and concern this has caused our customers." The bank has assured clients that no cyberattacks have been confirmed as the cause of this failure, and investigations are ongoing to determine the root of the issue.
To assist customers affected by the ATM outages, the bank has set up temporary cash withdrawal services at certain branches until 5 PM on the same day. These services are available at key locations, including the Osaka Main Branch Business Department and the Kobe Business Department.
The specific branches and sub-branches experiencing outages include the Nishinomiya Branch, Koshienguchi Branch, Shukugawa Branch, and many others across the region. A detailed list of the affected branches has been made available to customers, ensuring they are informed about where they can access services.
As part of its recovery efforts, Sumitomo Mitsui Banking Corporation is preparing to migrate to a new ledger system during the upcoming Golden Week holiday, scheduled for May 4-5. However, the bank has clarified that this planned transition is unrelated to the current system failure.
The temporary cash payment locations, which are operational until 5 PM, include several branches throughout the region. Customers are encouraged to use these facilities if they are unable to access ATMs. For inquiries regarding the system failure and available services, customers can contact the bank at 0120-559-622 until 9 PM on April 29, 2025.
This incident highlights ongoing challenges faced by financial institutions in maintaining robust and reliable systems. The rapid digitization of banking services has increased dependency on technology, making system outages particularly disruptive for customers. As banks continue to innovate and improve their services, ensuring system reliability remains paramount.
In conclusion, while the immediate impact of this outage is being addressed, it serves as a reminder of the importance of contingency planning and the need for banks to have resilient systems in place. As Sumitomo Mitsui Banking Corporation works to resolve the issues, customers are urged to stay informed and utilize the temporary services provided.
