In his address at the World Economic Forum's Annual Meeting 2026 in Davos, Mark Carney, the Prime Minister of Canada, warned that a world dominated by isolationism and self-interest would lead to greater fragility and poverty. He stated, 'A world of fortresses will be poorer, more fragile and less sustainable,' emphasizing the need for shared values and rules in international relations. Carney's comments reflect the growing global tensions and economic uncertainties, urging leaders to prioritize collaboration over convenience. He underscored that while short-term gains from transactionalism may seem appealing, they are not sustainable without a foundation of trust and cooperation. Carney, known for his significant roles in global economic governance, continues to advocate for sustainable finance and climate action, influencing discussions on the resilience of global markets and the importance of multilateral systems.
