Mizuho Bank submitted a report to the Financial Services Agency on the 31st, summarizing the causes and measures to prevent recurrence, due to a series of system failures such as the inability to use ATMs nationwide.
It is said that the system for promptly grasping the impact of the failure was insufficient, and that improvements will be made, including customer service.
Mizuho Bank experienced four system failures in quick succession in less than two weeks until the middle of last month.
Due to the largest system failure at the end of February, 80% of ATMs nationwide could not be used temporarily, and cash cards and passbooks could not be taken out from ATMs, and many people had to wait for a long time on the spot.
In response to a series of system failures, Mizuho Bank and its parent company Mizuho Financial Group issued a "report request order" based on the law from the Financial Services Agency, and on the 31st, a report summarizing the causes and recurrence prevention measures was issued. I submitted it.
According to the people concerned, the four system failures were caused by different factors, and the lack of a system to quickly grasp the extent of the effects of the system failures led to a delay in the initial response. I'm trying.
In the future, we plan to make improvements, including customer support, by changing the settings so that ATMs do not retain cash cards and passbooks even if a system malfunction occurs.
The Financial Services Agency will scrutinize the contents of the report and consider whether to issue an administrative punishment.
