Toss Bank said on the 10th that an error in exchanging Japanese yen (JPY) led to an incident amount of 27.6 billion won.
Toss Bank said in a disclosure the previous day that, excluding the recovered portion of the 27.6 billion won incident amount, a loss of 1.2 billion won (as of the disclosure date) is expected. Toss Bank added that it took incident measures through transaction corrections, clawbacks, and compensation.
At Toss Bank, from 7:29 p.m. on the 10th of this month for about seven minutes, an incident occurred in which an exchange rate in the 472 won per ¥100 range was applied when exchanging yen. At the time, the rate was in the 930 won per ¥100 range.
Toss Bank said the error was found to have occurred because the internal system that calculates the posted exchange rate based on rate information received from multiple external institutions did not operate normally during that period.
