On Wednesday, banks borrowed less money than markets expectedfrom the European Central Bank, in what investors saw as a reassuring sign that Europe's banking system is not as weak as previously feared.

"I don't quite see that myself," Rogers said, adding that the problems are worse now than at the beginning of the crisis. "Markets are looking ahead to more difficulties."

And he said he does not see why investors look at bonds as safe havens.

"I'm watching the bond market, I have no longs and no shorts," Rogers said. "It is a bubble which is developing; it's one of the few bubbles in the world which is developing."

"I think it's going to be a disaster and I plan to be selling them short sometime in the foreseeable future," he added.

Some economists have been calling for more stimulus money to be poured into the economy, but Rogers said this would be bad as it would help only certain categories and will have to be paid for by others.

"The people who receive the money think things are better, and they are better for them, but the rest of us have to pay the price," he warned.

'We Have Inflation Now'

In the US, officials and pundits recently said the bailout of Fannie Mae and Freddie Mac may end up costing taxpayers $1 trillion.

Prices are creeping up all over the world but some governments "lie" about inflation, according to Rogers.

"We have inflation now. Everybody who shops knows there is inflation… prices are going up," he said.

The US and the UK are among governments who "lie" about inflation, while Australia, China and Norway – countries that tightened monetary policy – are facing up to it, he added.

"My investment outlook is I am long commodities and short stocks. I don't own stocks in any place at all," Rogers said.

Rogers later clarified in an email to CNBC that he owns some shares.

"I do own some stocks that I have had for years, but I have been shorting and am short stocks," he wrote in the email.
