Russian currency after two weeks of stable growth began to fever. On Tuesday, she slipped to the dollar and the euro, and on Wednesday the trading session closed in different directions. So far, the ruble still has some time to strengthen its position, but the clouds over the “Russian” are gradually gathering. During yesterday's trading on the Moscow Stock Exchange, the ruble fell against the dollar by 17 kopecks, to 65.68 rubles, but rose against the euro - by 29 kopecks, to 74.82 rubles, according to the website of the trading platform. The latter is due to a sharp decline in the value of the European currency in the international market due to Italian budget problems. In the current situation, it will not be easy to strengthen the ruble. First of all, because Brent crude fell 2.75% on the eve, to $ 75.4 per barrel. This happened after the release of statistics on black gold reserves in the US. It turned out that over the past week they have grown. However, while the current oil prices remain above $ 70 dollars per barrel of Brent, the situation for the ruble remains positive. The tax period, which peaks today, is also affecting the ruble, Andrei Kochetkov, leading analyst at Otkritie Broker, said in an interview with Rossiyskaya Gazeta.. This will increase the demand for ruble resources.. This week the comments of the Bank of Russia after the Friday meeting of the board of directors on the key rate can give a certain positive dynamics to the Russian currency.. Unexpected support for “Russian” arrived from the USA. US presidential adviser on national security issues, John Bolton, yesterday at a press conference in Baku, said that Washington does not currently plan to impose additional sanctions against Moscow, Alpari analyst Vladislav Antonov notes, Prime reports.. The main risks to the stability of the ruble at the moment are the following. First, there are fluctuations in oil prices.. They can subside significantly due to the possible policy of Saudi Arabia and Russia to sharply increase the production of black gold.. Secondly, this is a possible tightening of US sanctions.. Despite Bolton’s positive statements, things can change after midterm elections to Congress.. If the Democrats get the majority, then new restrictions cannot be avoided. Third, it is the rapid strengthening of the US dollar against all currencies and a new round of crisis in emerging markets.. Fourth, acceleration of inflation. Finally, fifth, it is the possible resumption of purchases of currency in the free market by the Bank of Russia for the Ministry of Finance within the budget rule, the analyst believes. “However, to realize this risk, a substantial strengthening of the ruble is necessary in order not to provoke a sharp weakening of the ruble again and then heating up,” Kochetkov notes.. Thus, by the end of the year, the ruble will most likely not stay at current heights.. It will begin to weaken, with the result that the value of the dollar will return to about 67 rubles..
