Gold for immediate delivery rose as much as $25.40, or 2.7 percent, to $967.15 an ounce, the highest since July 22. April futures gained $22.10, or 2.4 percent, to $964.40. Some investors are buying precious metals on speculation government stimulus packages [and bank bailouts] will spur inflation, Fertig said.
