The euro is highly correlated to the level of inversion at risk
The european currency market with the cycles of the world economy. If this last is in full swing or recovery phase, the level of risk aversion is considerably reduced which is of benefit to the euro. Conversely, if the global economy is going through a crisis or a significant slowdown in the level of risk aversion increases, and the euro has depreciated on forex.

The euro depends on the internal crises of the area
If the euro is managed to maintain during the sub-prime crisis of 2007/2008 it is because the us dollar has collapsed. When it is low, however, this can often be explained by internal crises.
