AnÃlise da evoluÃÃo da inadimplÃncia bancÃria em cenÃrios de estresse atravÃs do uso de vetores autorregressivos / Analysis of the evolution of bank defaults in stress scenarios through the use of vectors autoregressive

Leandro Ferreira LeÃo de Alencar Oliveira 30 March 2015 (has links)
Esta dissertaÃÃo buscou identificar atravÃs de vetores autorregressivos (VAR) a relaÃÃo entre variÃveis macroeconÃmicas e a variaÃÃo do saldo das operaÃÃes inadimplidas a mais de 60 dias. Foram construÃdos dois cenÃrios de retraÃÃo econÃmica atravÃs da tÃcnica de impulso resposta. Ademais, a pesquisa identificou que a variaÃÃo do Produto Interno Bruto (PIB) e a variaÃÃo da Taxa Selic Acumulada, em perÃodos defasados, possuem grande correlaÃÃo com a variaÃÃo do saldo das operaÃÃes inadimplidas. Os resultados apontam que i) hà uma relaÃÃo inversa entre o crescimento do saldo das operaÃÃes inadimplidas e o crescimento do PIB na Ãpoca da inadimplÃncia, ii) hà uma relaÃÃo direta entre o crescimento do saldo das operaÃÃes inadimplidas hà mais de 121 dias e o crescimento da taxa Selic um mÃs apÃs a Ãpoca da inadimplÃncia, iii) os choques negativos no PIB afetam o crescimento do saldo das operaÃÃes inadimplidas e o crescimento da PCLD por um perÃodo superior a 12 meses. / This research sought to identify through autoregressive vectors (VAR) the relationship between macroeconomic variables and the change in the balance of operations over 60 days, building two scenarios of economic downturn by impulse response technique. The research identified that the variation of the Gross Domestic Product (GDP) and the Accumulated Selic Interest Rate in delayed periods have high correlation with the change in the balance of defaulting operations. The results show that i) there is an inverse relationship between the growth of the balance of defaulting operations and GDP growth at the time of default, ii) there is a direct relationship between the growth of the balance of defaulting operations for more than 121 days and growth the Selic rate one month after the time of default, iii) negative shocks on GDP affect the growth of the balance of the defaulting operations and growth of the Allowance for more than 12 consecutive months.
