Dent, bestselling author and financial newsletter writer, told CNBC Tuesday that he sees a stock market crash in the United States starting in the third quarter of 2013 and continuing for a year and a half.
Dent said real estate prices and stocks would plummet more than 60% by the end of 2014, or sooner, meaning the Dow Jones Industrial Average would fall below 6,000. He also said the United States would be close to bankruptcy by then.
Dent cited U.S. demographic shifts and the nation's debt crisis as the main drivers of a crash. He said had it not been for the U.S. Federal Reserve's recent moves to stimulate the economy, the stock market would already have collapsed.
"We call this the economy in a coma," he said. "Basically, without these trillions of dollars of stimulus, we would be in a downturn, in a depression, because we also have $42 trillion in private debt, the greatest debt bubble in history, and that needs to unwind."
