LONDON, December 20: The London Metal Exchange (LME) base metal prices mostly closed higher on Monday as a weaker US dollar spurred fund buying. Zinc briefly rose to its highest point since December 1999 near 1,242 US dollars per tonne. The emerging hedged hedged the price of zinc to US$1,237, which was a US$14 increase from the composite transaction closing on Friday. A trader said, “From a technical point of view, the zinc futures market is bullish, but we do not rule out the next few deals. Corrective movements are occurring on a daily basis, as profit-taking may occur before the end of the year." "The decline in the dollar has stimulated further fund buying, while fundamentals look good, although there is almost no fundamental news." Potentially cautious, in the research report, said, “We are cautious about these high prices in the short term, because prices are approaching key resistance levels and there is little fundamental news to support them. In addition, we believe that most of the US dollar’s ​​decline is over. The rebound in energy prices is still a problem, and freight rates have not shown signs of abating.†Barclays Capital pointed out that investors' strong sentiment for zinc is likely to drive the period to about 1,40 per tonne. 0 US dollars. Three-month copper rose 44 US dollars to 3,077 US dollars per ton, aimed at the October high of 3,175. Barclays Capital said, "The fundamentals of the outlook still provide solid support, investors still have enough room to push forward copper, now the market Copper's net long position is less than half of the 4,8000 lots recorded in 2003." "In the LME market, relatively low open interest levels also indicate that the participation of speculative forces is not high." Copper supply tensions have eased further . LME spot/three-month copper discount fell to US$110 from last week’s 120-130 USD. Three-month aluminum rose 24 US dollars to 1,857 US dollars per tonne, up 1.3%, thanks to a weaker dollar. A few metal analysts said that the new regulations will not reduce the supply of copper, aluminum and nickel. China is the world’s largest producer of aluminum, but the government hopes that the aluminum industry will cool down, due to the industry’s consumption of large amounts of energy, while China’s energy supply is insufficient. Nickel rose by 1,150 U.S. dollars to 14,650 U.S. dollars, soaring nearly 8%. A market analyst pointed out in the research report that "Niloni broke through the resistance at 13,650/700 and triggered a large amount of short covering and fund buying, and it was light. As a result, the market condition has further risen by US$800. Since there is almost no resistance to a straight-line rise, it is necessary to remain vigilant about the trend of the market outlook.†The nickel future hit a three-week high of US$14,650 per ton. The nickel price rose in early trading, benefiting from China's January 1, 2005 export tariffs on copper, aluminum and nickel. During Asian time, the three-month nickel of LME rose above the resistance level of $13,600. This triggered short-term fund stop-loss buying. Since then, the price of nickel has risen further beyond $14,000. The next key resistance level for nickel is US$14,800. Because China’s copper and nickel exports are insignificant globally, China’s export duties on copper and nickel are unlikely to reduce global supply. Analysts expect that the new regulations will curb domestic base metal output. From January to October of 2004, China’s copper exports increased twice, and nickel exports increased by more than 60%, both of which benefited from the increase in copper prices and nickel prices in the international market. During the period, Tin held flat at US$8,775 and lead rose by US$12 to US$942.
