René Benko bought real estate and department stores, promising a "golden future" for city centres. Now his empire, Signa Holding, is insolvent. Like a house of cards, the opaque system threatens to collapse, and numerous German cities would be affected.

High interest rates and construction costs have hurt Benko's business model, but the bankruptcy raises questions: Why does Signa suddenly have five billion euros in debt? Why did many investors and municipalities get involved in pompous but risky deals? And what will become of the department stores of Galeria Karstadt Kaufhof, which has already gone through two bankruptcies and devoured many millions of euros in taxpayers' money?
