PayPay Securities resumes Japanese stock and ETF trading after system outage

PayPay Securities announced on October 14 that it has resumed trading for all Japanese stocks and Exchange Traded Funds (ETFs) following a service disruption. The suspension, which began around 10:15 AM on October 13, prevented users from buying or selling these assets.

The company identified the cause as a malfunction in the order receiving and processing system of Mizuho Securities, an external connection partner. PayPay Securities clarified that the issue was not caused by a cyberattack or unauthorized access. The firm stated it will work with relevant companies to ensure system stability and prevent recurrence.
