On the big picture, we see 3 inputs, which are QE1+QE2+QE3 and there effect on the market, the relaunch of it, the ending period and the effect on EURUSD .
With the end of QE3, baring in mind that FED President Yellen is still keeping the schedule of tappering, will there be a natural decrease of EUR against USD? Does ECB really need to decrease the interest rate to 0 or bellow in order to push EUR to loose value against USD? Or will it come naturally?
Bare in mind that so far ECB made a lot of statement, but no action. Perhaps ECB is waiting for the end of the EP elections, or ECB President will take a stance of FED. Let's wait and see.
