SURGING COMMODITIES: Commodity prices rose after Fed Chairman Ben Bernanke said the central bank could approve more stimulus measures if weak growth persists in the U.S. economy. Gold, industrial metals, energy and agricultural products all rose.
DOLLAR'S IMPACT: Bernanke's comments caused the dollar to weaken. That benefited commodities, which are priced in dollars. A weaker dollar makes them cheaper to buy for investors who use other currencies like the euro or the Japanese yen.
GOLD PRICES: Gold for August delivery rose $23.20 to settle at $1,585.50 an ounce. That was a record in dollar terms but below its peak in the early 1980s after accounting for inflation.
