Marc Faber, who advised investors to buy U.S. stocks in March 2009 as the Standard & Poor’s 500 Index began a rally of as much as 86 percent, said U.S. Treasurys are a "suicidal" investment.

Government bonds are likely to decline, said Faber, who publishes the Gloom, Boom and Doom report. After bottoming in December 2008, the 10-year Treasury yield rose as high as 3.9859 percent in April on government measures to stimulate the economy. Concern about a second recession in three years sent yields lower through October.

“This is a suicidal investment,” Faber said in a telephone interview from St. Moritz, Switzerland. “Over time, interest rates on U.S. Treasurys will go up. Investors will gradually understand that the Federal Reserve wants to have negative real interest rates. The worst investment is in U.S. long-term bonds.”

On Nov. 3, the Fed said it would buy an additional $600 billion of Treasurys through June, expanding record stimulus and risking its credibility in a bid to reduce unemployment and avert deflation. U.S. bond funds had withdrawals of $8.62 billion in the week ended Dec. 15, the most in more than two years, according to Washington-based Investment Company Institute.

Rising Yields

Treasury 10-year note yields will rise to 5 percent from yesterday’s level of 3.349 percent, Faber said, without specifying a time frame. As bonds fall over the next decade, he said investors should buy precious metals, real estate or equities. U.S. debt has returned 5.7 percent in 2010, more than erasing last year’s 3.7 percent loss, according to a Bank of America Merrill Lynch index.

Faber correctly predicted in May 2005 that stocks would make little headway that year. The S&P 500 gained 3 percent. He was less prescient in March 2007, when he said the S&P 500 was more likely to fall than rise because the threats of faster inflation and slower growth persisted. The S&P 500 then climbed 10 percent to its record of 1,565.15 seven months later, and ended the year up 3.5 percent.

Faber said equities may continue to advance as the dollar weakens as a result of loose monetary policy.

“If you print money, the currency goes down and the S&P 500 goes up,” he said. “By the end of 2011, people will look at 2012 and think 2012 could be a very bad year because the policies applied are not sustainable and create a lot of instability. Investors may look at 2012 and 2013 with horror.”
