Trump and Federal Reserve Chair Waller may confront each other this week over interest rate hikes

Stubborn high inflation has led Trump to confront Federal Reserve Chairman Waller this week, as the market prepares for the Fed to raise interest rates despite the president's demands.

Economists warn that if the Fed does not support a rate hike on Wednesday, its "credibility" will be at risk. Trump reiterated that the U.S. should have the "lowest interest rates in the world" and may be dissatisfied with a rate increase.
