RESUMO

There are different methods for determining the minimum capital of a financial institution. The academic literature related to this subject essentially groups them into two approaches. The first uses asset volatility to obtain potential unexpected losses and, therefore, the minimum capital. This approach is present on the first pillar of the New Basel Capital Accord. The second approach uses earnings volatility to obtain the maximum negative change of this variable to calculate the minimum capital, given a confidence level and a time horizon. This potential maximum change must be translated into capital by using a risk-free rate. In other words, the earnings volatility approach aims to obtain a minimum capital which, invested in a risk-free rate, can generate a return to cover the potential maximum negative change in earnings. This research empirically tests the two approaches on the 50 biggest banks present in the Brazilian financial system. The objective is to verify statements present on the academic literature and related to the differences between the approaches.
