This paper finds that the pandemic has had a statistically and economically significant effect on the capital structure of Portuguese companies. Findings show that companies seem to have increased their leverage ratio and long-term debt during the pandemic years, 2020 and 2021. The results of this study contrast with previous literature about other crises, such as the global financial crisis of 2008- 2009, and previous studies on the impact of economic uncertainty on capital structure behavior. This possibly reflects the widespread fiscal, monetary, and prudential support throughout the pandemic.Esta dissertação estuda o efeito do COVID-19 na estrutura de capital das empresas portuguesas. Este artigo conclui que a pandemia teve um efeito estatisticamente e economicamente significativo na estrutura de capital das empresas portuguesas. Os resultados mostram que as empresas parecem ter aumentado seu índice de alavancagem e dívida de longo prazo durante os anos de pandemia, 2020 e 2021. Os resultados deste estudo contrastam com a literatura anterior sobre outras crises, como a crise financeira global de 2008-2009 e estudos anteriores sobre o impacto da incerteza económica no comportamento da estrutura de capital. Isso possivelmente reflete o amplo apoio fiscal, monetário e prudencial durante a pandemia.engLeverageCapital structurePandemicThe impact of COVID-19 on Portuguese firms’ capital structuremaster thesis203252713
