Since the dark hours of the interwar period, debt has historically been a very sensitive subject in Germany. The parliamentary debate initiated this Thursday by the far-right Alternative for Germany party has again shown the hypersensitivity of deputies on this subject. In Berlin, the debt brake rule is almost sacred. Anchored in the Constitution since 2009, it limits new debts raised by the federal government to 0.35% of GDP. In 2018, this corresponded to 12 billion euros.
