HOW DID REGULATORS DEAL WITH UENO?

Questions have focused on whether regulators adequately supervised ueno as it expanded, particularly because the country's central bank chief, Carlos Carvallo, had previously been head of the digital lender.

The central bank has denied any conflict of interest, saying Carvallo recused himself from all decisions related to ueno.
