IMF lowers global economic outlook.

 In no real surprise, the IMF has cut its global growth estimates again, predicting a rise of 3.3% this year (down from 3.5%) and 3.6% in 2013 (down from 3.9%). The fund has raised its estimates for U.S. growth slightly to 2.2% in 2012 and 2.1% in 2013, but forecast that China will weaken to 7.8% this year and grow 8.2% next year. Key factors include the U.S. "fiscal cliff" and the fate of the euro.
