Abstract

La tendance mondiale actuelle est marquée par une fragmentation géopolitique croissante, entraînant des divergences politiques, des chaînes d'approvisionnement plus longues et une incertitude accrue. Des événements récents tels que la guerre entre la Russie et l'Ukraine, les conflits au Moyen-Orient et les différends commerciaux entre les États-Unis et la Chine témoignent de cette incertitude mondiale. L'indice d'incertitude mondiale n'a cessé d'augmenter depuis les années 1990 et a atteint un sommet en 2020 en raison de facteurs tels que les tensions commerciales entre les États-Unis et la Chine, le Brexit et la pandémie de coronavirus.
