Paraguayan lawmakers have accused the president of a conflict of interest and questioned whether authorities failed to act on warnings about the lender’s financial position.The collapse of Ueno, which held $850m in public funds, has left more than half of Paraguay’s population without access to their accounts, drawing intense scrutiny over the government’s relationship with the bank and financial regulators’ effectiveness.“My greatest wish is that the return of those funds be guaranteed, that the deposit guarantee fund fulfil its purpose, and that public funds — as well as the resources that belong to all Paraguayans — be protected,” Pena said in a Thursday video address where he apologised for failing to prevent the crisis.The crisis has also prompted the resignation of Paraguay’s central bank chief, Carlos Carvallo, and arrest warrants for eight Ueno executives, who later turned themselves in.Paraguay’s attorney general has ordered three criminal investigations into the bank’s collapse, including its regulatory oversight and the placement of public funds in the institution.If Pena is convicted in an impeachment trial, he would lose the lifetime Senate seat and associated legal protections ordinarily granted to former Paraguayan presidents.
