In a tweet following the election, the European Union said he had been elected as the eurogroup’s new president and that he will take up his post on January 13.
Mário Centeno had been overwhelming favourite to win the race to succeed Dutchman Jeroen Dijsselbloem, who has been at the helm for nearly five crisis-ridden years.
He defeated Luxembourg’s Pierre Gramegna, Slovakia’s Peter Kazimir and Latvia’s Dana Reizniece-Ozola.
Mr Centeno will take the helm at a time when the eurozone is in far better shape than the one that existed during Mr Dijsselbloem’s tenure.
The economy is growing strongly, while worries over Greece’s future in the bloc have subsided and the country is poised to exit its bailout era next summer.
