Germany has had its worst bonds sale since the launch of the euro as investors are becoming increasingly concerned about the stability of the eurozone.
The finance agency which issues the bonds said Germany was able to place only 3.6 billion euros' worth of 10-year bonds from the 6 billion euros it had hoped to sell to investors.
That meant that the central bank had to pick up the remaining 39 percent of the issue.
Germany is the strongest economy among the 17 members of the eurozone, and some analysts said the disappointing auction on November 23 could be a sign that the debt crisis may be spreading toward the core of the eurozone.
