CNBC’s Jim Cramer on Friday said that FedEx’s warning of worsening economic conditions suggests the Federal Reserve is doing better in its inflation effort than expected — meaning the central bank could take a step back after its meeting next week.”If Fed chief Jay Powell watched our interview last night … he might discover that he’s made more progress whipping inflation than he might realize,” Cramer said.”Maybe Powell will hit us with another 75 basis point hike right here and then say maybe it’s time to take a more measured approach in order to assess how things are going,” he added.The “Mad Money” host’s comments came after FedEx, a bellwether company for the state of the economy, warned on Thursday of a decline in global shipments and an impending world recession.Stocks closed down on Friday as Wall Street digested the news, with the major averages recording their fourth losing week in the past five weeks.Cramer also previewed next week’s slate of earnings.
