No. of bitstreams: 1 61070100623.pdf: 435548 bytes, checksum: b66651487a8f6639fd39ff2b9bf5d7ad (MD5) Previous issue date: 2009-04-17T00:00:00Z / This study examines whether the sale of credit portfolios are used by financial institutions for risk management, according to Stanton (1998) and Murray (2001) or to capture resources, as indicated in Cebenoyan and Strahan (2001) and Dionne and Harchaoui (2003). Two hypotheses on credit portfolio sales were tested: 1) promote rating improvement to the remaining portfolio, or 2) drive to financial leverage - with worsening on the remaining portfolio -, controlling for recourse existence and to whom those assets were sold. The sample includes quarterly information from 145 financial institutions from the first quarter 2001 to second quarter of 2008. The results provide empirical evidence that financial institutions use these sales to improve the rating of the remaining credit portfolio, i.e. they transfer, in most cases, low quality assets, assuring good ratings and improving liquidity. Additionally, following Harchaoui and Dionne (2003) proposal - which besides testing, demonstrating that regulatory requirements promote leveraging in high-risk assets – it was observed the relationship between the Basel Index and credit portfolio rating. The conclusions were similar to those found by Dionne and Harchaoui(2003): the more adequate – higher Basel Index - the financial institution, the greater its chances of having a bad quality credit portfolio. / Este estudo analisa se as vendas de carteiras de crédito são utilizadas por instituições financeiras para gestão de risco, de acordo com Stanton(1998) e Murray(2001) ou para captação recursos, como apontado em Cebenoyan e Strahan(2001) e Dionne e Harchaoui(2003). Duas hipóteses foram testadas quanto às vendas de carteira de crédito: 1) implicam em melhor rating na carteira remanescente; ou 2) promovem alavancagem financeira - com piora na carteira remanescente -, controlando para a existência de coobrigação e para quem esses ativos foram transferidos. A amostra inclui informações trimestrais de 145 instituições financeiras do primeiro trimestre de 2001 ao segundo trimestre de 2008. Os resultados oferecem evidências empíricas de que as instituições financeiras utilizam estas vendas para melhora do rating da carteira de crédito remanescente, ou seja, elas transferem, em sua maioria, ativos de baixa qualidade, garantindo bons ratings e melhorando a liquidez. Adicionalmente, seguindo a proposta Dionne e Harchaoui(2003) - que além de testar, evidenciam que exigências regulatórias promovem alavancagem em ativos de alto risco - foi observada a relação entre o Índice de Basiléia e rating da carteira de crédito. As conclusões foram semelhantes às encontradas por Dionne e Harchaoui(2003): quanto mais adequada – maior Índice de Basiléia - uma instituição financeira for, maiores as chances de ela possuir uma carteira de crédito com qualidade ruim.
