The social investment approach has been advocated as a blueprint for recasting European welfare states since the years of the Lisbon Strategy. After the Euro crisis squeezed the fiscal space available for welfare recalibration, the question has been raised as to whether social investment could withstand the economic turmoil. Relying on a new welfare expenditure dataset constructed from various Eurostat sources, this article looks at the budgetary recalibration of 27 EU welfare states from the launch of the Lisbon Strategy to the aftermath of the Euro crisis (2000 to 2014). It compares the financial efforts that governments have put into social investment- and social protection-oriented policies, highlighting the different trajectories taken by EU welfare states at the crisis crossroads. Four scenarios for welfare recalibration are put forward, based on the social investment perspective and its critiques. The results show that the overall progress made by social investment in welfare budgets since 2000 came to a halt with the outbreak of the crisis. Bleaker scenarios materialised, whereas EU welfare states pursued retrenchment rather than investment, or had to face harsher budgetary trade-offs, expanding social investment to the detriment of social protection.
