US Inflation Could Hit 200%: Dr. Doom

The US risks being hit by Zimbabwe-style hyperinflation and there are signs that the world's biggest economy risks turning into a banana republic, Marc Faber, author of the Gloom, Doom & Boom report, told CNBC's "Asia Squawk Box."

"In the US, we have a totally new school, and it’s called the Zimbabwe school," Faber said. "And it’s founded by one of the great leaders of this world, Mr Robert Mugabe, that has managed to totally impoverish his own country. And that is the monetary policy the US is pursuing."

The government's increased intervention in the economy is likely to slow down economic growth because history shows that every time the private sector shrinks to make way for the government sector, the economy suffers, he said.

Asked whether the US risked being faced with 200 percent inflation, Faber answered: "Well, not yet. Not yet. But I think eventually. If I look at government debt in the US, and debt in general, I think the only way they will not default physically on their debt is to inflate."

The Federal Reserve's policy of printing money and the government's intervention in the economy might undermine the US's economic and political clout, Faber warned.

"Well, I wrote two years ago a report entitled 'Is America becoming a banana republic?' And there are some features that characterize banana republics- totalitarian states, very strong government intervention into the economy, and the polarization of wealth," he said.

"And we have all these trends occurring in the US. We are not yet there. And in theory it could be reversed, but I doubt it will be," Faber added.

Because of these factors, US government and corporate bonds, including that of CNBC parent General Electric, should be downgraded, he said.

"Yeh, I think GE should be a junk bond. But I also think the US government should be junk," Faber said, adding: "I don’t pay much attention to rating agencies. The rating agencies have totally failed over the last 3-4 years to identify sick companies."
