Brazil’s Central Bank moved to calm concerns after Nubank customers received messages incorrectly stating that the digital lender had been closed and that clients should recover funds through the Credit Guarantee Fund.

The alert, sent through Nubank’s app and by email around midday, told users: “Nubank has been closed. Click here to find out how to claim funds available in the FGC”, El País reported.

The message also informed customers that deposits were protected up to BRL250,000 ($49,360) per individual.

Nubank later said the notification resulted from “a one-off operational error” and stressed that the incident had no impact on customer data, platform security or the company’s financial position.

“This incident is in no way related to the security of the platform, the protection of customer information, or the stability of the company,” Nubank said in a statement. “Nubank’s operations continue as normal, secure, and stable,” it added.

Brazil’s Central Bank also issued a statement denying the claims. “The information that the Central Bank has decreed the extrajudicial liquidation of Nubank is incorrect,” the authority said.

Founded in São Paulo in 2013 by Colombian entrepreneur David Vélez, Nubank has expanded across Latin America and now serves 135mn customers in Brazil, Mexico and Colombia.
