The prices of German Bunds fell significantly on Friday.
The trend-setting futures contract Euro Bund Future fell by 1.04 percent to 150.98 points by the afternoon.

"In view of the persistently high demand for labour, the danger of a wage-price spiral is growing." The US central bank is therefore stepping on the brakes more vigorously.
