Jakarta. Bank Central Asia (BCA), Indonesia’s largest private lender, denied rumors on Friday that its investment fund accounts had been compromised, resulting in losses of up to Rp 70 billion ($4.5 million).

The allegation circulated online earlier this week, suggesting a breach in BCA’s systems affecting investor fund accounts (RDN). But the bank rejected the claims, stressing that its digital platforms remain secure.

“The information is not true,” Hera F. Haryn, BCA’s Executive Vice President of Corporate Communication and Social Responsibility, said in a statement on Friday. “We can confirm that BCA’s systems are safe and no financial losses have been suffered by our customers.”

Hera added that the lender is working closely with securities firms and authorities to conduct a thorough investigation into the reports.

“BCA continuously implements multilayered security strategies and risk mitigation measures to safeguard customer data and digital transactions,” she said.

The bank reiterated its commitment to protecting client funds as cyberattacks on financial institutions grow increasingly frequent across Indonesia.

The rumors centered on alleged irregularities at Panca Global Sekuritas, which holds investor accounts at BCA. The securities firm has not immediately commented on the matter.

Shares of BCA (IDX: BBCA), one of the most valuable companies on the Indonesia Stock Exchange, were up by 0.96 percent in Friday trading
