In various countries, favorable measures have been continuously introduced to support the economy and the stimulus of slight easing of the epidemic situation, attracting funds to pay attention to the metal's continued low rebound. LME copper has tested the US$ 5,000 mark, while domestic demand rose by more than 1,000 once on the premise of good epidemic control and start of demand. At present, the epidemic situation in foreign countries has not yet reached an inflection point, and the U.S. has taken the lead in increasing sharply. The trend of the global economy continues to worry the market. Most short-term profit-making operations of funds will hinder the upward breakthrough of copper prices. On the spot, due to the impact of the epidemic on the subsequent reduction in the organization of imported recycled copper and the shortage of domestic products, the market supply will become even more tight in April. The electricity copper inventory in Guangdong region has also been reduced from 100,000 tons in the previous period to below 80,000 tons now, and its low price has replaced the consumption of some recycled copper. Based on the above situation, short-term copper price is expected to fluctuate slightly under the multi-short factor, but LME US$ 5000 and domestic copper futures 40,000 are short-term upward breakthrough resistance levels.
