Global financial crisis (2008-2009)
Global credit markets froze and demand for German machinery, cars, and chemicals collapsed. German exports and industrial output fell sharply, pushing Europe's largest economy into a deep recession.
Exports recovered only after world trade rebounded in 2010.
The episode showed how much Germany's growth depends on global investment cycles.
September's rebound rests on the same export machine, making it sensitive to any slowdown in Europe, the US, or China.
