Gold for immediate delivery added 0.5 percent to $1,290.60 an ounce, while wheat in Chicago advanced 0.8 percent. The gauge is up 1 percent this week in the best winning streak since the eight-week rally through Feb. 1. U.S. Federal Reserve Chairman Ben S. Bernanke said this week the central bank’s bond purchases “are by no means on a preset course� and could even be expanded if economic conditions warrant.

The S&P GSCI has risen 0.7 percent this year as oil in New York jumped 18 percent and natural gas advanced 11 percent. West Texas Intermediate crude was little changed after climbing to a 16-month high yesterday as data showed the number of Americans who filed for jobless benefits dropped to the fewest since early May.
