A service of the

Europe faces a changing fiscal landscape shaped by rising investment needs, high public debt and growing geopolitical pressures. This Forum examines how the European Union’s fiscal framework can respond to these challenges, highlighting the limitations of existing fiscal arrangements and exploring options for adapting European fiscal policy to a more demanding strategic environment. The contributions consider the treatment of public investment, the restructuring of legacy sovereign debt, alternative approaches to financing common European defence and the implications of geopolitical exposure for fiscal outcomes.
