Former hedge fund manager and Goldman Sachs alumnus Raoul Pal isn't one to shy away from making bold predictions. Back in November 2014, Pal, who is currently the publisher of the Global Macro Investor newsletter and the founder of Real Vision TV, said the U.S. dollar index was poised to make a move the likes of which hadn't been seen in "many, many years." Now, after the dollar index surged 10 percent, Pal is out with a new prediction, and it could spell trouble for global equities.



"I think the dollar will go up for another few years from here, so I'm expecting to see, by the end of this year, the dollar up maybe 20 percent," said Pal on CNBC's "Fast Money" this week.



"So we've got another 10-12 percent or so to go this year alone, and then next year something similar," he added.



If true, those predictions could have dire consequences for the global market.
