Oct. 17 (Bloomberg) -- The efforts of finance ministers and central banks worldwide may soon begin to restore investor confidence, said Bill Gross, who manages the world's biggest bond fund.

``We're talking weeks here,'' said Gross, in an interview on Bloomberg Radio.

Gross's Total Return fund has returned 4.4 percent annually over the past five years, beating 99 percent of its peers in the government and corporate bond fund category as of Oct. 16, according to Bloomberg data. Newport Beach, California-based Pacific Investment Management Co., a unit of Munich-based Allianz SE, has $840 billion of assets under management.
