In recent years, it has become widely acknowledged that multilateralism as a mechanism, as a means of tackling global challenges, is in deep decline.

This is sovereign debt restructuring, where stakeholders engage in resolving one of the most politically and financially sensitive issues of our time. Despite challenges—many of which stem from geopolitical tensions—multilateral financial diplomacy remains effective and continues to yield tangible outcomes.
