U.S. unconventional monetary policy and emerging countries : exchange rate and capital flows dynamic ; Politique monétaire américaine non conventionnelle et pays émergents : dynamique des taux de change et des flux de capitaux

Abstract

The implementation of the U.S. unconventional monetary policy in 2008 coincided with massive capital inflows and exchange rate appreciation for emerging markets. They implicate the Federal Reserve to pursue a « Beggar-thy-neighbor » policy and to create spillovers. In 2013, following the announcement of the « Tapering », some emerging markets suffered from significant financial crises. In this context, this thesis intends to study how the U.S. unconventional monetary policy led to capital flows and exchange rate movements spillovers. As the normalization of this monetary policy is initiated, understanding the international implications of the Federal Reserve's decisions is essential to contain potential risks. For this purpose, we firstly study mechanisms and their impacts on emerging countries by a literature review. We show that the Fed monetary policy caused capital flows and exchange rate spillovers in the last decade. Then, we reveal empirically that the impacts exhibit heterogeneity over time, depend on implementation modalities of the U.S. central bank as well as on the countries. We establish that there is no real symmetrical impacts between accommodative and normalization periods. As a result, the normalization would not lead to capital outflows in emerging countries. Finally, we examine the means that emerging countries can adopt to limit spillovers. We demonstrate that capital controls and macroprudential policies can be efficient to reduce capital inflows. More precisely, the effectiveness of capital controls is conditioned by their accumulation. The more the country adopts it, the more it limits spillovers. Considering macroprudential policies, the intensity of the U.S. monetary policy and the quality of the emerging countries' institutions are two main determinants of their effectiveness. ; La mise en place de la politique monétaire non conventionnelle en 2008 aux États-Unis a coïncidé avec d'importants mouvements de capitaux et de taux de change dans les pays émergents. Ces derniers ont accusé la ...
