On the first question, many economists who pay close attention to the dynamics of the duration have already voiced their opinions. Julia Coronado, founder of research firm MacroPolicy Perspectives, said that the Fed is definitely moving slowly, and they need to catch up.

Mark Zandi, chief economist at rating agency Moody's, was even more blunt in saying that the Fed had made a mistake and that they should have made the decision to cut rates months ago.

"It feels like another 25 basis point rate cut in September is not enough, and a 50 basis point rate cut and more aggressive monetary policy measures are what the Fed needs to do." Zandi said.

JPMorgan Chase Chief United States Economist Michael Feroli also believes that the Fed should make a decision to cut interest rates at the Fed's Monetary Policy Committee meeting at the end of July, and in the current situation, they have to cut rates as soon as possible.

He expects the Fed to make two consecutive 50 basis point rate cuts at its September and November monetary policy meetings.
