全銀システム刷新、半年先送り　昨年の障害で、稼働２８年５月に

　全国銀行資金決済ネットワーク（全銀ネット）は１７日、銀行間の資金決済を担う「全国銀行データ通信システム（全銀システム）」の刷新時期を半年先送りすると発表した。稼働は当初計画の２０２７年１１月から２８年５月にずれ込む。昨年秋に発生した大規模障害の再発防止を優先するためで、安全対策として刷新後も当面は従来システムを並行稼働させる。
　全銀システムは１日に平均８３３万件、約１４兆円の資金取引を処理する決済インフラの中核で、２４年７月時点で１１００の金融機関が接続する。２３年１０月に更新作業で不具合が起き、１９７３年の稼働開始以来、初めて大規模な障害が発生。他行向け振り込みが滞るなど、２日間にわたり約５６０万件の取引に影響が出た。（2024/10/17-20:23）

Japanese Banks' Payment Clearing Network, or Zengin-Net, said Thursday that it will postpone the planned revamp of its Zengin interbank financial settlement network system by six months to May 2028.
   The renewal, previously scheduled for November 2027, was moved back because Zengin-Net will give greater priority to preventing a recurrence of a massive system failure in autumn last year.
   As a safety measure, the existing system will be operated in parallel for the time being even after the renewal.
   The Zengin system is the core of the country's financial settlement infrastructure, which processes an average of 8.33 million transactions per day, worth about 14 trillion yen. As of July this year, 1,100 financial institutions were connected to it.
   In October 2023, the failure occurred during renewal work, triggering its first large-scale service disruption since the system was launched in 1973. In the incident, 5.6 million transactions were affected over two days, including delays in fund transfers to other banks.
