There are several key drivers for merging pension funds into a single Pan-European pension fund. This includes reducing operational risks through more centralized oversight and control, achieving efficiency gains from economies of scale, and lowering costs through a single European entity with a unified governance structure and lower regulatory burden. A single pension fund could also allow for funding flexibility, tax optimization, and cost transparency while easing multinational corporate transactions and workforce mobility across borders. Overall, a Pan-European approach has the potential to simplify administration and risk management for multinational companies while improving the sustainability of pension systems across the EU.
