TEMPO.CO, Jakarta - A brokerage firm PT Mirae Asset Sekuritas Indonesia has initiated an internal investigation following the alleged loss of customer investment funds totaling Rp71 billion. The company stated it is coordinating closely with the Financial Services Authority (OJK) and the Financial Transactions Analysis and Reporting Center (PPATK).
"To ensure that the case disclosure process can be carried out as effectively as possible according to prevailing regulations," Mirae Asset Sekuritas management stated in an official release on Tuesday, December 2, 2025.
According to management's initial analysis, changes observed in customers' investment portfolio assets may have occurred because account access was shared with external parties. The management noted, "This finding is still in the analysis stage."
Mirae Asset affirmed that it will pursue legal action should the investigation uncover any misuse, false reporting, or actions detrimental to the company's reputation. The firm also assured the public that its platform and operational systems continue to function normally.
Customer Reports and Legal Action
The case originated with a report filed by a customer identified as Irman with the Indonesian National Police's Criminal Investigation Agency (Bareskrim Polri) on October 6, 2025.
Irman's legal representative, Krisna Murti, claimed his client lost Rp71 billion after receiving unexpected transaction notifications on the Mirae Asset Sekuritas application at 7:34 p.m. Jakarta time. Krisna explained that his client previously held a substantial portfolio of blue-chip stocks in major companies, such as BBCA, BBRI, and Telkom. However, this portfolio suddenly vanished and was replaced by shares in companies unfamiliar to him.
"Our client never executed those transactions," Krisna asserted at the Bareskrim Polri building on Friday, November 28, 2025.
Consequently, Irman filed a police report (Number LP/B/583/XI/2025/SPKT/BARESKRIM Polri) against three Mirae Asset Sekuritas officials: President Director Tae Yong Shim, Director Tomi Taufan, and Director Arishandi. The report alleges criminal acts of fraud and illegal access, including violations of the Fund Transfer Law and the Electronic Information and Transactions Law.
Multiple Victims Claim Similar Losses
Adding to the complexity, several other customers have come forward claiming similar incidents. One such customer, Leni, reported discovering suspicious transactions on November 10, 2025. "We reported it previously, but they claimed the mistake was on our side," she stated.
Krisna Murti indicated that there are multiple victims beyond Irman and Leni, estimating the total customer losses to be more than Rp90 billion.
