On Monday, gold hit a record for the fourth day in a row, boosted by growing expectations for US interest rates to remain exceptionally low as the economy struggles, while silver came in range of 30-year peaks. Spot gold rose 0.3% to $1,280.20 an ounce by 0935 GMT, having hit a record peak of $1,283.35 earlier. US gold futures for December delivery rose 0.3% to $1,281.70an ounce.

Spot gold prices have risen by more than 16% this year, driven by the desire among investors for a safe store of value in light of major currencies, equities and bonds becoming increasingly volatile. Reflecting keen investor interest in gold was another rise in holdings of bullion in the world?s largest gold-backed exchange-traded fund, the SPDR Gold Trust, which rose by another 6 tonne on Friday, bringing net inflows to 2.0 tonne so far this month.

Silver prices, which have risen by 17% in the last five weeks alone, were less than 1.5% below their highest level in nearly 30 years on Monday. The world?s largest silver-backed exchange-traded fund, the iShares Silver Trust, said its holdings rose to 9,381.74 tonnes by Sept 17 from 9,343.69 tonne on Sept 16. The platinum group metals, too, rose in line with the rally in gold.

In base metals, copper touched a five-month high a the greenback slipped along with reports of further quantitative easing in the US.

In agriculture commodities, corn and soybean futures extended gains fueled by doubts over U.S. corn yields, dry weather in a soy-growing part of Brazil, and a crop-killing cold snap in Canada.

On the Chicago Board of Trade(CBOT), soyabean futures rose more than 2% to the highest level since Sept. 1, 2009, corn set a new peak in almost two years and wheat hit the highest level in more than a month.

In Europe, feed wheat futures in London hit a 17-month top and Paris milling wheat prices matched a contract high as concerns about yields in the US corn harvest gave fresh momentum to a wheat market that soared last month after an export by drought-hit Russia. In CBOT December corn added 1.80% to $5.22-1/2 a bushel by 1151 GMT. Front-month corn has surged 61% from the low in June on strong demand and expectations of lower US yields.
