NEW YORK: Oil prices continued to set new post-recession highs Monday as forces loyal to Muammar Gaddafi pounded rebels near a key oil port in Libya. It's unclear how long the country's oil exports will be cut off, and traders prepared for a worst-case scenario in which world supplies would be under pressure for months. Benchmark West Texas Intermediate crude for April delivery gained $1.02 to settle at $105.44 a barrel on the New York Mercantile Exchange. The price almost hit $107 per barrel earlier in electronic trading, the highest level since Sept. 26, 2008. In London, Brent crude fell 93 cents to settle at $115.04 per barrel. The prospects of further unrest in Middle Eastern countries drove investors to seek safe-haven assets. Gold spot prices hit a record high of $1,444.40 an ounce while silver rose as high as $36.52 an ounce, its highest since early 1980. “If we do see tension escalating further, then we could witness a new high in gold,” said Ong Yi Ling, investment analyst at Phillip Futures in Singapore. US Treasury debt prices also rose on a safe-haven bid as stocks fell. The Dow Jones industrial average lost 57.94 points, or 0.48 percent, to 12,111.94, while the Standard & Poor's 500 Index declined 9.46 points, or 0.72 percent, to 1,311.69.
