Jeffrey Gundlach, chief executive of Doubleline Capital, said on Wednesday that the "low rate-low volatility" market environment went on for so long that now "the unwind will be turbulent and not over in a couple of days."
Gundlach, who is known as the Wall Street bond king, told Reuters that bitcoin was the "lead horse" of risk assets and its recent plunge has had a cascading effect on other risk assets.
Gundlach had correctly predicted that if the 10-year U.S. Treasury note yield went above 2.63 percent, U.S. stock investors would be spooked.
"Clearly, the market gets shaky when the 10-year hits 2.85 percent," Gundlach said. "Just look at this week, and today. Makes one consider what could be coming if 10s push over 3 and 30s (30-year Treasury bond) over 3.22 percent."
The 10-year yield is currently trading around 2.83 percent. Gundlach said it is "hard to love bonds at even a 3 percent" yield. "Rising interest rates are a problem and the U.S. is in debt and there is massive bond supply," Gundlach said.
