MOSCOW, may 6 - RIA Novosti/Prime, Elena Lykov. Exchange rate of the dollar against the ruble is Already more than 3 weeks provides investors feel safe falling, then being strong: fifteen April this year, the dollar dropped below 50 rubles twice. Last news asked analysts to answer, coincidence or a trend And make predictions on further movement of currencies. on Wednesday, the dollar fell to 49, 59, 55, 87 rubles, while during the trading day the Price of Brent crude oil rose above $ 69 per barrel. Already more than 3 weeks of Exchange, the dollar-ruble goes up and down in the range 49, 5-54 ruble, And currently the rate is closer to the lower boundary of this trading range, draws the attention of the chief analyst organization Management Savings Alexander potvin. As the season of monthly tax payments ended at the end of April, at the present time, the dynamics of the ruble depends on the situation on the oil market, he says. "on Wednesday the quotations of oil Brent has again updated their annual maxima (69 per barrel), while we do not see an equivalent one-year lows on dollar exchange rate. Why?" - he asks the question. And answers: "Maybe because to trade the dollar against the ruble in the carry trade has become profitable. Each time, lowering rates (softening of monetary policy), the Central Bank will play against the ruble ". Strategy carry trade consists of borrowing in the national currency of the country, setting low interest rates, convert, And investing them in the national currency of the countries that have high interest rates. Senior analyst at Forex Club Alena Afanaseva also emphasizes that the ruble shows a stable position, but recently With great reluctance moving higher, despite the sharp appreciation in the prices of petroleum products. "Yeah, the strengthening of the ruble a month ago was supported by the combination of several factors in the form of speculative demand of fans carry trade, And the peak of tax payments that caused the activity of the companies-exporters," she comments April the strengthening of the ruble. Since then, the RF Central Bank has Already lowered its interest rate at 1, 5% 12, 5%, making the Russian currency almost attractive to investors, however, such a confident movement of "black gold" up ruble could provide greater support, she explains the dollar's fall below 50 rubles on may 6. Key to strengthen the ruble became several factors. First, the most important role in this dynamic plays rising prices for petroleum - quotes "black gold" is currently being traded in the step from the level of 70 dollars per barrel, where they were in early December 2014, notes the analyst of investment company "Finam" Anton Soroko. Secondly, the lack of negative news From the political arena, he also says." of course, there are risks that With the onset of summer, the situation may deteriorate, And on the issue of sanctions against Russia as long as no clarity no. But at the present time, these factors have taken a back seat, the most on the background of the so-called dividend rally in the stock market, which also is positive for the domestic currency, " the analyst lists. Additional Demand for Russian ruble creates the Ministry of Finance, says the analyst of "Alpari" Vladislav Antonov." As in April, the Finance Ministry supports the ruble auctions on placing of bonds of Federal loans. The demand for bonds exceeds the supply in two or three times. For the second quarter of 2015 it is planned to place bonds in the amount of 250 billion rubles, " he commented. Another factor that affects the growth of the ruble Is a decrease in the dollar on the Forex market, says Antonov. he predicts that if the Forex currency market the dollar continues correctional movement, then the pair dollar-ruble will move to around 45 rubles, Because the fall in the dollar price of "black gold" will grow. "After the fall of the American currency below 48 rubles on the background of the fall of the dollar on international currency markets, the residents of Russia may begin to panic. This applies to the 1st and foremost those who bought the dollar at a price higher than 60 rubles, they will put additional pressure on the dollar, "- says the analyst of " Alpari ". by assumption Alena Afanasyeva from Forex Club, amid the ruble's strengthening is Possible in the future intervention of 2 factors: interventions from the Central Bank who is not willing to let the national currency strengthened too rapidly, And more and more often-sounding talk about the new wave of hostilities in the Donbass. "most likely, these two factors will limit the strengthening of the dollar-ruble range 48-49 rubles, even in the care of Brent above $ 70 per barrel ", - predicts it. And Soroko from "Finam" believes that further strengthening of the rouble in the conditions of stabilisation of the prices for oil products has the ability to be limited by the level of 50 rubles per dollar, And in the near future especially likely consolidation of the domestic currency in a broad sideways trading range. "This level is, in General, a comfortable, Both for budget And for clients who feel the influence of a weak ruble by a sharp increase in the prices of consumer goods," he commented.
