The yuan-to-ruble exchange rate grew by 0.27% in a day, to 12.76 rubles.

The wave of sales was caused by the increase in the key rate of the Bank of Russia to 19%, explained Alexander Shepelev, an expert on the stock market at BCS World of Investment.

"On the one hand, the increase in the key rate is moderately negative for stocks, since lending and debt servicing become more expensive, economic activity is lower. In addition, competition from debt market instruments and deposits increases. On the other hand, the monetary factor is significant, but not decisive for the stock market. Some companies benefit from the growth of rates," the expert explained.

The leaders of growth were preferred and ordinary shares of Surgutneftegas (+5.7% and +5.2%), Magnit securities (+5.03%), NLMK stock prices (+3.80%), and Ozon receipts (+3.78%). Solidcore shares rose by 0.97%.
