The euro weakened broadly after ECB President Mario Draghi cut forecasts for economic growth and inflation in the euro zone at the central bank’s post-policy meeting press conference.

The central bank also cut the inflation outlook to 2.5% in 2012 and to between 1.1% and 2.1% in 2013.
The ECB left rates unchanged at 0.75% earlier, in a widely expected decision.
