Objective: To analyze a risk contribution of the financial sector to the risk of the Brazilian stock market, considering the following global crises: of subprimes; European debt; and Covid-19.
Background: Because it is capable of changing several generalized forms, systemic risk and the contagion effect are subjects that are constantly studied in the finance literature. In addition, the financial sector, because the interaction with other economic sectors, is considered one of the sectors most susceptible by the economy.
Method: To achieve the objective proposed in this article, the risk management model called Conditional Value at Risk (CoVaR), by Adrian and Brunnermeier (2016), was used. The sample includes the real daily returns of the representative indices of the financial sector and the Brazilian stock market. The analyzed period started in January 2007, ended in March 2020.
Results: The main results suggested for the period of world crisis, except for European debt, contribute to the risk of the financial sector to the Brazilian stock market and cause an increase in calm consumption. In addition, in the Covid-19 crisis, the risk contribution was the highest among the observed economies.
Contribution: The findings can assist academics, investors, regulators and taxes in better assessing the effects of a global crisis on a country's drive market, as well as identifying the sensitivity of the financial sector in stress studies , making it possible for measures to be adopted both for the supervision of the crisis and for its prevention.
Keywords: Systemic risk; Contagion effect; Financial sector; CoVaR; World crises.
