Gold climbed toward $4,500 an ounce on Monday, building on previous gains due to softer US economic data that lowered expectations for immediate Federal Reserve tightening. Weak inflation, declining consumer sentiment, and softer retail sales pressured the dollar, causing the dollar index to drop near 99. Investors are awaiting the FOMC minutes and Fed Chair Kevin Warsh’s speech at Jackson Hole for new policy signals. MCX October gold futures rose 0.5% to ?155,316 per 10 grams.
