Ponta, who took over as interim finance minister earlier today, said he would likely sign the dismissal on Monday.
He did not name a replacement for Ghetea, who served as president of CEC Bank since 2007.
Ghetea was recently at the center of a scandal regarding a credit line CEC Bank has extended to Ioana Basescu, the elder daughter of Romanian President Traian Basescu.
Former finance minister Daniel Chitoiu said in November last year that Basescu phoned and asked him not to replace Ghetea as head of CEC Bank, without giving a reason for his request.
