The Euro rocketed on Tuesday, August 21, as the optimism over bold ECB action to stem the 17-member bloc's debt crisis grew. The shared currency soared 1.03% to $1.2472. At the same time, the ICE Dollar Index erased 0.68% to 81.9. Moreover, better-than-expected Spain debt auction boosted the Euro as well, with Spain selling 4.51 billion euros of 12- and 18-month bonds.
