The Securities and Exchange Surveillance Commission (SESC) is conducting a forced investigation into a former employee of Sumitomo Mitsui Trust Bank over allegations of insider trading. The investigation reportedly concerns activities dating back to 2022, when the individual was in a deputy position. It is suspected that the former employee may have made approximately 30 million yen through illegal stock trading. In a separate case, a former employee of Nomura Securities has been arrested on suspicion of fraud, accused of defrauding a 70-year-old female client out of 10 million yen by falsely claiming to offer a company savings plan with a 2% interest rate. The suspect allegedly used the funds to pay off debts related to gambling activities. These incidents highlight ongoing concerns regarding financial misconduct within Japanese financial institutions.
