  • Morgan Stanley's Chetan Ahya tells CNBC the Fed needs to cut rates aggressively this week.
  • Traders are pricing in a 76% probability of a 25 basis point cut, according to the CME's FedWatch Tool, with a 24% probability of the more aggressive cut.
  • "When you're thinking about the economy, the job market and retail sales will be lagging. What is leading is Capex and corporate profitability, and that is already deteriorating," Ahya says.

A top economist at Morgan Stanley told CNBC on Monday that he expects the Federal Reserve to cut interest rates by 50 basis points this week because of weak business investment in the United States.

A report from the Commerce Department last week showed that business investment in the U.S. declined 5.5% in the second quarter, adding to the mixed economic data for the Fed to sort through as it prepares to vote on whether to shift its benchmark interest rate.
