Mário Centeno is a Portuguese economist and politician who served as Finance Minister from 2015 to 2020 and as President of the Eurogroup from 2018 to 2020, and later became Governor of the Bank of Portugal (Banco de Portugal). His nomination for vice‑president of the European Central Bank matters because a senior Portuguese official at the ECB could influence euro‑area monetary policy decisions that affect interest rates and the economy in Portugal.
