Resumen

El objetivo de este trabajo es el análisis del impacto de la unión monetaria en las oportunidades de diversificación del riesgo de las carteras de deuda pública en la zona euro. Para ello, se examina la existencia de tendencias comunes en la evolución de la rentabilidad a diez años de los países de la UE-15 durante el período 1994–2008. A pesar de que se encuentra evidencia a favor de la cointegración múltiple, los resultados apoyan la existencia de más de una tendencia entre las rentabilidades a largo plazo de los países de la UE-15. Además, cuando se centra el análisis en los países de la zona euro, aunque la interdependencia aumenta, se sigue rechazando la existencia de una única tendencia común. Estos resultados tienen importantes implicaciones para los inversores en términos de sus posibilidades de diversificar el riesgo en una contexto de una moneda única.

Abstract

The aim of this study is to analyze the impact that the monetary union has had on risk diversification opportunities in European public debt markets. We examine the common trends in the evolution of daily 10-year yields in EU-15 countries during 1994–2008. Despite finding evidence in favor of multiple cointegration, the results support the existence of more than one trend between long-term EU-15 sovereign yields. Furthermore, when we focus our analysis on the euro zone, although interdependency increases, we can still reject the existence of a single common trend. These results have important implications for investors in terms of their risk diversification possibilities in a single currency context.
