Overview

Mercedes Rosalba Aráoz Fernández (born 5 August 1961) is a Peruvian economist, academic and public official. She is best known for serving as Second Vice President of Peru in the administration of Pedro Pablo Kuczynski and for a short, contested assumption of presidential authority during the political crisis of 2019. Aráoz has combined academic work with roles in government and the private sector, and her career has touched on economic policy, parliamentary politics and executive leadership.

Education and early career

Trained as an economist, Aráoz has worked as both a researcher and a teacher. She is commonly described as a professor in university programs and has been involved in policy research and consultancy. Over the course of her professional life she moved between academia, advisory roles and positions in public administration, bringing technical expertise to economic and administrative portfolios.

Political career and offices held

Aráoz entered elected national politics and later held high executive posts. Key positions held include:

2019 constitutional dispute

In late September 2019 the Peruvian Congress moved to suspend President Martín Vizcarra and subsequently named Aráoz as acting president through a disputed parliamentary resolution. Her appointment was immediately challenged: many institutions, including the Peruvian armed forces, continued to recognize Vizcarra as the legitimate head of state. The legal and political legitimacy of the congressional action was widely questioned by domestic and international observers. Faced with the contested situation and institutional resistance, Aráoz announced her resignation as vice president on 1 October 2019 and did not consolidate a lasting claim to the presidency.

Significance and later assessment

Aráoz's public profile reflects the intersection of technocratic expertise and partisan politics in contemporary Peru. Supporters point to her economic training and administrative experience; critics emphasize the fragility of political institutions exposed during the 2019 crisis. Her brief, contested assumption of executive authority remains a notable episode in discussions about constitutional order, separation of powers and military neutrality in Peru.
