Cramer: GDP number was ‘devastating’

Cramer to Fed: Stay dovish

As the Federal Reserve concludes its two-day meeting, CNBC's Jim Cramer said Wednesday the central bank should keep interest rates low.

"Today is a surprising day. Almost every trend that we were looking at, whether it is for earnings or these macro numbers, [and] they're being turned on their heads," Cramer said on "Squawk on the Street."

Cramer made his remarks after the government reported that the gross domestic product rose a meager 0.2 percent in the first quarter, well-below the expected 1 percent.

"This is a devastating number. Futures were down a lot because people are so afraid that the Fed is going to be out of sync with this number," Cramer said.

"If they truly are [data dependent], they have to be as dovish as they can be, because this kind of number …makes you think it's not the weather. It's the fact that the dollar has gotten in the way of major industrial companies."
