Even mightier dollar? Have no fear, analyst says

Treasury Secretary Jack Lew has said that it is in the nation's best interest to have a strong dollar, but it doesn't feel that way for earnings.

Alan Ruskin, a top foreign exchange strategist at Deutsche Bank AG, told CNBC's "Squawk on the Street" on Wednesday that a stronger greenback will no doubt have some negative impact on earnings but it's not all bad.

"If you look at the overall economy and you said we're going to grow 5 percent in Q3 and we're probably going to grow above 3 percent in Q4, there's no real problems here from a broader macro standpoint," he said.

He added that even though it's been hard to keep up with the dollar's move, "the U.S. economy is more robust than pretty much all of the other economies out there, and it can withstand a stronger currency."

Ruskin projects that the relationship between the dollar and the euro will be subparity in the longer haul and that it might be at 90 cents by 2017.
