41	Um estudo da estrutura a termo de taxas de juros de títulos públicos prefixados e o modelo de Svensson Frota, Silvia Franciele Padilha 03 February 2017 (has links) A Estrutura a Termo de Taxas de Juros (ETTJ) é um elemento essencial para formulação da política monetária. Ela é capaz de indicar as expectativas do mercado financeiro em relação as taxas de juros futuras. Nesse trabalho estudamos a formação da ETTJ com enfoque maior na matemática envolvida, haja visto que na literatura esse assunto em geral é tratado apenas com foco na economia. Demonstramos as relações matemáticas entre as taxas de juros à vista, futuras e instantâneas. Estudamos também o modelo matemático empírico de previsão da curva de juros proposta por Lars E. O. Svensson (SVENSSON, 1994). Esse modelo é de fácil aplicação pois necessita de poucos parâmetros para se ajustar a curva de juros. Por esse motivo esse modelo tem sido amplamente usado em Bancos Centrais de diversos países inclusive pelo Banco Central do Brasil. Concluímos com uma aplicação do modelo de Svensson (SVENSSON, 1994) utilizando os preços dos títulos prefixados do Tesouro Direto. / The Term Structure of Interest Rates (TSIR) is an essential element for the formulation of monetary policy. It is able to indicate the expectations of the financial market in relation to future interest rates. In this work we study the formation of TSIR with a greater focus on the mathematics involved, since in the literature this subject is generally treated only with a focus on economics. We prove the mathematical relation between spot, future and instantaneous interest rates. We also study the empirical mathematical model of forecasting the interest curve proposed by Lars E. O. Svensson (SVENSSON, 1994). This model is easy to apply since it requires few parameters to adjust the interest curve. For this reason, this model has been widely used by Central Banks of several countries, including the Central Bank of Brazil. We conclude with an application of the Svensson (SVENSSON, 1994) model using the prices of fixed-rate Treasury Direct securities.

43	La liberté contractuelle du banquier : réflexions sur la sécurité du système financier / The contractual freedom of the banker : reflections on the safety of financial system Maymont, Anthony 17 December 2013 (has links) La liberté contractuelle du banquier est une liberté parmi d’autres. Cependant, elle est la plus sensible dans lamesure où elle peut avoir des répercussions sur son activité. A priori sans limites aujourd’hui, cette liberté auraitmême des conséquences indéniables sur la sécurité du système financier en facilitant le phénomène des« bulles ». Le contrat, situé au coeur de l’activité bancaire et financière, serait ainsi la cause de cette réalité. Leschocs récents, telles les crises financières, imposent l´examen détaillé des opérations bancaires nationales maisaussi internationales, notamment celles les plus dangereuses. Encore méconnue, la mesure de la libertécontractuelle du banquier s’avère nécessaire pour en proposer une relecture. L’objectif n’est donc pas d’excluretoute liberté au banquier mais de définir le degré de liberté contractuelle à lui accorder pour chaque opération.L´idée étant de lui octroyer un niveau satisfaisant de liberté tout en assurant la sécurité du système financier.L’enjeu repose finalement sur la conciliation de l’impératif contractuel, résultant de la liberté contractuelle dubanquier, avec l’impératif de sécurité du système financier, nécessaire à la pérennité des banques et del’économie mondiale. / The contractual freedom of the banker is a freedom among the others. However, it is the most sensitive in so faras it can affect on his activity. Apparently unlimited today, this freedom would have even undeniableconsequences on the safety of the financial system by facilitating the phenomenon of “speculative bubbles”. Thecontract, situated in the heart of the banking and financial activity, would be thus the cause of this reality. Therecent shocks, such as financial crises, require the detailed examination of the national but also internationalbank transactions, especially the most dangerous. Still ignored, the measurement of the contractual freedom ofthe banker proves to be necessary to propose a review. The aim is not thus to rule any banker’s freedom out butto define the degree of contractual freedom to grant to him for each transaction. The idea being to grant him asatisfactory level of freedom while ensuring the safety of financial system. The stake rests finally on theconciliation of the contractual requirement, resulting from the contractual freedom of the banker, with the safetyrequirement of the financial system, necessary for the sustainability of banks and worldwide economy.
