Mizuho Bank clients were further inconvenienced Thursday by delays in its cash-transfer services related to account settlements for the 2001 business year, Mizuho officials said.
Mizuho Bank, a new retail lender launched Monday under Mizuho Holdings Inc., said computer problems caused the delays when the bank was transferring cash from client accounts to the designated recipients.
The Mizuho group had planned to settle accounts for the 2001 business year on Monday, after suspending operations over the weekend ahead of the group's reorganization. As of Thursday, however, some of the payments and transaction data still hadn't been received.
A spokesman for Mizuho Bank said the group is investigating the cause and scale of the computer malfunctions.
On Monday, most of Mizuho Bank's automated teller machines were crippled by a faulty computer that prevented customers from making deposits or withdrawals.
The ATM problems also caused 147 Mizuho Bank accounts to be erroneously debited, even though customers were unable to make any withdrawals.
Mizuho Holdings, the world's largest banking group by assets, made a fresh start Monday when its three core banks merged into Mizuho Bank and Mizuho Corporate Bank which serves major corporate clients.
The three banks were Dai-Ichi Kangyo Bank, Fuji Bank and Industrial Bank of Japan.
