In connection with the recent international crisis, economic activity in Morocco's key partner countries, including the European Union, has slowed significantly, raising fears over the spread of recessionary factors in Morocco. However, macroeconomic fundamentals of Morocco and the strength of domestic demand, could partially offset the effects of the crisis. However, it revealed the degree of trade integration with Morocco and risks borne by the slowdown in foreign demand. The present work aims to assess the synchronization between real Moroccan and European cycles, through an approach based on the study of phenomena of co- movements and relies on parametric methods for detecting turning points of cycles activity.
