Abstract in Portuguese
A taxa de câmbio real dólar é formada em mercados à vista e futuro, operados necessariamente por intermédio de instituições financeiras que lucram tanto na corretagem quanto na posição proprietária de contratos. Essa característica cria um risco moral sobre os interesses de hedgers e intermediadores. Este trabalho investiga através do modelo econométrico do Vetor Autorregressivo VAR, testes de Causalidade e Função Resposta ao Impulso se é possível constatar empiricamente que as instituições financeiras, atuando em conjunto, podem influenciar significativamente a taxa de câmbio real/dólar. As conclusões apontam que o valor dos contratos futuros de dólar exerce grande influência sobre a taxa de câmbio à vista, o que implica em uma necessidade de supervisão constante da autoridade regulador, para coibir possíveis práticas de manipulação.

Abstract in English
The Brazilian Real / US Dollar exchange rate is formed both on spot and future markets, operated necessarily by financial institutions; organizations profit both with intermediation and proprietary positions of contracts. Such characteristic incurs a moral hazard concerning hedgers and financial institutions interests. This research uses econometric models such as VAR, causality tests and impulse response function to investigate if financial institutions acting together are able to significantly influence the Real / Dollar exchange rate. The results show that the future exchange rate exercises great influence on the spot rate, reaffirming the necessity of constant supervision on financial institutions by the regulatory authority in order to restrain market manipulation.
