Fed might not raise rates in 2015: Gross

NEW YORK (Reuters) - The Federal Reserve could find itself challenged to raise U.S. interest rates this year as global growth remains sluggish and inflation subdued, closely watched bond investor Bill Gross said on Monday.

"With the dollar strengthening and oil prices declining, it is hard to see even the Fed raising short rates until late in 2015, if at all," said Gross, who oversees the Janus Global Unconstrained Bond Fund, in a collection of investment views posted online by Janus Capital Group.

With global economies struggling, Gross said, "it's going to be very difficult for the Fed as the major central bank for the global reserve currency to raise interest rates to historical levels."

That could keep the Fed's major interest rate capped at around 1 to 2 percent, Gross said, keeping yields on the benchmark 10-year U.S. Treasury note not far from its "seemingly ridiculous" current yields.

That note last traded at a yield of 2.0476 percent on Monday morning.

"Interest rates in almost all developed countries will remain near the zero bound, as well," Gross added.

Gross quit Pimco, the bond firm he helped co-found, in September, shocking markets as he moved to smaller rival Janus Capital Group.

Sometimes called the bond king for his decades-long track record in fixed income, Gross remains widely followed.

On Monday Gross sounded a cautionary note on global growth.

"Aside from the United States, the growth outlook for developed countries and many emerging ones is subpar," he said.

"Do not look, therefore, for economic growth to be the magic elixir for 2015."

Because of potential volatility, he said, "investors should be flexible and consider more liquid securities. Fixed income with shorter maturities is one starting place."

The Janus Global Unconstrained Bond Fund, which Gross started managing in October, attracted an estimated $770 million in November, bringing its assets to more than $1.2 billion, according to Morningstar data.

The Federal Reserve has not raised benchmark interest rates since 2006, instead slashing them to near zero to boost growth in the world's largest economy during the financial crisis.

Last month Fed policymakers signaled that a rate hike could be coming this year.

But Gross on Monday suggested higher markets will require "the potion of monetary policy" in 2015. Yet much of the gains from such loose policy could already be priced into markets, he added.

"Be prepared for low returns in almost all asset categories," Gross said.
