[pt] Este trabalho analisa o impacto dos requerimentos de liquidez da Basiléia III na gestão de liquidez dos bancos. A partir de uma base de dados que engloba bancos de todos os países signatários do Comitê de Basiléia III, foram definidos indicadores de liquidez bancária com base nas práticas utilizadas na literatura econômica e que busquem servir de proxies aos indicadores propostos pelo Comitê. Foram então verificados os cronogramas de implementação dos novos requerimentos de liquidez estabelecido por cada país. Acompanhou-se, então, a evolução dos indicadores de liquidez antes e depois do novo requerimento de liquidez instituído pelo Comitê. Foi observado alta estatisticamente relevante nas proxies de liquidez de curto prazo. Por outro lado, o resultado das regressões que buscam acompanhar a evolução de liquidez de longo prazo demonstraram quedas estatisticamente significativas. / [en] This paper analyzes the impact of Basel III liquidity requirements on banks liquidity management. Indicators of bank liquidity were defined based on the practices used in the economic literature and that seek to serve as proxies to the indicators proposed by the Committee. Database was built including banks from all countries that are signatories to the Basel III Committee. The timelines for implementation of the new liquidity requirements established by each country were then verified. The evolution of the liquidity indicators before and after the new liquidity requirement established by the Committee was followed. A statistically significant elevation was observed in short-term liquidity proxies. On the other hand, the result of the regressions that seek to follow the evolution of long-term liquidity showed statistically significant declines.

This dissertation explored the efficacy of the new Basel III banking standards in SACU, grounded on the conjecture that they are not reflective of economies of SACU, but are merely an intensification of Basel II, rather than a substantial break with it. Firstly, loans and assets were tested for causality, since Basel III believes growth in these variables led to securitization. The leverage ratio has been introduced in Basel III as an anti-cyclical buffer. The OLS technique was employed to test for its significance in determining growth in bank assets. SACU feels the impact of debt, with credit is marginally treated in Basel III and is not introspective of the realities of its economies. ANOVA tests using debt, credit and GDP were done to determine a better method of addressing cyclicality. The leverage ratio was insignificant in Namibia, with debt and credit having momentous impacts on GDP in SACU. / Economics / M. Com. (Economics)
