CNBC's Jim Cramer said Tuesday he speaks to dozens of CEOs every week and they're all worried about a slowdown in earnings growth.
"There are many parts of the economy that are slowing," Cramer said "Squawk Box." "I would love to say it's all systems go. But my work does not show that."
"The pastiche of industrialist CEOs I deal with right now, everything from retail to oil and gas to steel, it doesn't matter. It changed. It changed in the last six weeks," he said.
Earlier Tuesday, Cramer tweeted that CEOs "all had high hopes" but "no longer."
Later on "Squawk on the Street," Cramer said he worries that the slowdown "is not just in housing."
Cramer also reiterated his comments about a shift at the Federal Reserve from being data-dependent to being blinded by the desire to normalize interest rates.
"I really think [Fed Chairman Jerome] Powell is going to walk back things. He's too thoughtful of a man to stay on autopilot," the "Mad Money" host said Tuesday. "Autopilot means crash landing."
