"I'm not the only person who knows there's turmoil coming," Rogers said in an interview with Real Vision TV released Friday. "And people are looking for ways to protect themselves."

Rogers is worried about the increasing valuation of gold and the US dollar, as well as the US stock indexes, which he said are up despite most underlying stocks being down.

Meanwhile, many investors are seeking shelter in gold and the US dollar, but neither are safe, Rogers said.

"I own a lot of US dollars, though," he added. "Not because it's a safe haven, but because people think it's a safe haven. And when the world falls apart, people will put their money into the dollar. That's going to mean the dollar's going to go up."
