The MSCI Mining & Metals Index fell sharply after a 25 percent gain in the first half of the year. This was due to investors' concerns about the prospects for demand for steel and copper in China due to the crisis of Evergrande construction company, one of the world's leading purchasers of these metals. Papers of mining companies lost significantly in price over the summer amid the collapse in prices for iron ore. The latter rose to a record high of $233 a tonne in May and then began to fall sharply after China imposed restrictions on steel production. In August, according to Bloomberg, its price fell by 26%; last Monday it reached $94. Copper since the beginning of the week shows negative dynamics, which was also triggered by financial difficulties of the above-mentioned Chinese developer. Its fall on Comex exchange during yesterday exceeded 0.22%.
