Elon Musk says he's worried about the Fed 'crushing' the value of the entire stock market

• The Fed could crush the value of the entire stock market, Elon Musk warned at Tesla's fourth quarter earnings call.
• That's because the Fed's rate hikes are discouraging investors from dipping into stocks, which spells trouble for firms.
• Musk has blamed the Fed for Tesla's dismal performance in 2022, when the EV-maker lost $600 billion in market value.

Elon Musk is worried the Federal Reserve could ravage the stock market by jacking up interest rates too high. 

The Tesla CEO delivered his concerns to investors on the electric vehicle maker's fourth-quarter earnings call on Wednesday. 

"I think the Fed needs to be very cautious about having a Fed rate that potentially exceeds 6%," Musk said at Tesla's fourth quarter earnings call, referring to the central bank's aggressive fight against inflation.
