Abstract in Portuguese
A atividade bancária envolve em suas operações diversas formas de riscos. Dentre esses riscos está o risco de crédito representado como sendo uma medida de incerteza relacionada ao recebimento de um valor compromissado concedido pela instituição financeira ao tomador de empréstimo. Nesse trabalho são apresentadas as principais metodologias de quantificação do risco de crédito como Credit Metrics, KMV, Credit Portfolio View e CreditRisk+. Esta última metodologia é aplicada a quatro portfólios de financiamentos à pessoa jurídica, evidenciando o Capital Econômico Alocado - CEA, a distribuição do risco de crédito em diferentes ramos e setores de atividade da economia e o spread necessário para cobrir as perdas esperadas e inesperadas. Após essa quantificação do risco de crédito, verifica-se, utilizando o conceito de Risk Adjusted Returno on Capital - RAROC, qual dos quatro portfólios de empréstimo bancário foi o mais rentável para a instituição financeira.

Abstract in English
Banking operations involve several kinds of risk. Among those risks, there is one called the credit risk associated with a measure of uncertainty related to receiving pré-committed values from the financial institutions credit-takers. In this research, the main methodologies used for the quantification of credit risk are discussed: Credit Metrics, KMV, Credit Portfolio View e CreditRisk+. The later is then applied to four company-targeted lending portfolios, thus showing Allocated Economic Capital AEC, the distribution of credit risk in different sectors and industries in the economy, and the necessary spread for covering expected and unexpected losses. After this effort to quantify credit risk, proceed to check, using the concept of Risk Adjusted Return on Capital RAROC, which of the four lending portfolios proved to be more profitable for the financial institution.
