Moreover, economists expect the German economy to shrink by at least 6 percent this year after a dramatic fall in world trade hit the nation's key export machine.

But releasing the latest figures, the statistics office also revised up the nation's gross domestic product data for the first-quarter to show a 3.5 percent contraction instead of a previously estimated 3.8 percent.

The release of the second-quarter German growth figures also came in the wake of a batch of surprisingly strong data from the nation with exports surging by 7 percent in June and factory orders jumping by 4.5 percent.
