The Financial Services Agency (FSA) issued an administrative order to Mizuho Bank and Mizuho Financial Group on Wednesday that will allow the financial watchdog to oversee system management at the banking group, a rare punishment following a series of technical failures.

The FSA instructed Mizuho Bank to submit a plan on its system renewal and maintenance it is considering for the time being. The FSA also instructed Mizuho Bank to submit a report on the recent automated teller system glitch by Oct. 29. The agency will decide whether a fresh administrative punishment will be necessary once all inspections are finished, it said.

The FSA apparently believes that it would be difficult to fully resolve the issue at the major Japanese banking group if system management is left entirely in the hands of Mizuho Bank and Mizuho Financial Group, Japan's third-largest lender by assets.

The agency plans to send technology experts to the Mizuho side to allow the government agency, the professionals and the bank to jointly engage in the operations and updates of the system with the aim of mitigating the risks of a glitch happening again, informed sources said.

A spokesperson for Mizuho declined to comment.

Mizuho has been hit by a series of high-profile technical meltdowns this year, despite having spent more than $3.6 billion to overhaul its systems in 2019. That revamp followed two large-scale breakdowns in 2002 and 2011.

The administrative measure comes after seven system failures have occurred at the Japanese megabank this year, with the latest disrupting about 100 automated teller machines on Sept. 8. Mizuho has yet to get to the bottom of the series of failures.

A third-party report commissioned by the bank found its corporate culture is to blame for its long history of tech system failures, creating an atmosphere where managers are reluctant to express opinions and unable to respond well to crises.

The Nikkei newspaper, which first reported the FSA's planned move, said the regulator will jointly manage the system with the bank, and order that system updates and maintenance be carried out under its control.

The management structure of the system may also be reviewed if necessary, the Nikkei said.

The regulator will determine where management responsibility lies after clarifying the cause of Mizuho's recent technical problems, it said.
