U.S. interest rates are likely to attract capital for now, and that makes the dollar a buy - probably.

Is the greenback golden? Maybe so.

At least, that's the view of Jeff deGraaf of Renaissance Macro Research.

"The dollar's made a double bottom, in our view, and we think we're going to look at dollar strength going forward, not just for the remainder of the summer but probably for the next several quarters if not a couple of years," he told CNBC's Simon Hobbs.

Noting the rash of interest rate cuts by central banks around the world, deGraaf adds, "we still have interest rate differentials that are attracting capital to the U.S., and that's going to result in a stronger dollar."

Willie Williams, director of institutional derivative sales at Societe Generale, also likes the dollar - kind of.

Williams argues that the dollar is in the middle of its range against the euro, and while he thinks the euro eventually will weaken, he suggests waiting for it to move higher before entering a short trade. "The market is now waiting to see if the Federal Reserve is going to step in and do some form of more aggressive quantitative easing," he says.
