AbstractThis article traces the emergence of the concept of ‘group solution’ and its manifestations in insolvency law and bank resolution as an alternative to the rigid entity-by-entity approach. The rise of this concept can be linked to the recognition of the specificity of problems related to the insolvency of multinational enterprise groups, arising from group operational and financial interconnectedness. This has not happened at once, but has resulted from the evolution of views and ideas, evident in hard and soft law instruments of the 2000s and the 2010s. In light of this important development the article explores the concept of a group solution, its rationale, scope of application and limitations. It concludes that despite the gradual acceptance of the group phenomenon, a group solution has not been formed as a coherent and well-defined legal principle. Instead, it represents a variety of approaches, tools and practices, which pursue different policy objectives underpinned by different societal values. Among them are asset value maximization, business rescue, the protection of financial stability and the preservation of banks’ critical functions. With all its flexibility, a group solution has one pervasive limitation—it cannot trump the interests of individual group members and their creditors. At the same time, in order to realize the full potential of a group solution, it is necessary to embrace the group-sensitive and forward-looking interpretation of creditors’ interest, facilitating commercially sensible and practical group solutions.
