Mairéad McGuinness
Former European Commissioner for Financial Services, Financial Stability and Capital Markets Union (2020-2024)
Mairead McGuinness shaped Europe’s financial architecture during one of its most transformative periods. As European Commissioner, she drove policy on financial sector stability, Capital Markets Union, and Banking Union, the frameworks that govern European finance today. Before her Commission role, she served sixteen years as MEP, including as First Vice-President of the European Parliament, giving her unparalleled insight into how Brussels works and where it’s heading. She currently serves as Vice-President of the European People’s Party, keeping her at the centre of Europe’s strategic direction. What makes her exceptional is her ability to translate complex policy into clear insight. She spent 24 years as an award-winning journalist and broadcaster in Ireland before entering politics, so she knows how to cut through the noise and explain what actually matters. She brings an insider perspective on the EU’s approach to digital innovation, the balance between regulation and growth, and how policy decisions in Brussels impact global business. University College Dublin recognised her impact with an Honorary Doctorate in 2024.
