This book analyzes the impact of Solvency II. In recent years, EU legislators have sought to introduce fundamental reforms. Whether these reforms were indeed fundamental is critically investigated with regard to a post-crisis piece of financial legislation affecting the EU’s largest institutional investors: Solvency II. Namely, the last financial and economic crisis, the worst financial catastrophe of the last decade, revealed that financial law in particular was not sufficiently mature to maintain the existence of a robust and trust-worthy financial system that could protect society from economic decline. The work also makes concrete recommendations on achieving a more sustainable future. As such, it offers a valuable resource for anyone who is interested in the financial system, the EU political economy, insurance, sustainability, and Critical Legal Studies.
