The ruble has been losing ground for the fourth trading session in a row. During this time, he lost about 2 percent in pairs with the dollar and the euro, returning to the August highs after a short pullback. If the Russian currency “does not change its mind”, it risks escalating weakening after overcoming important levels of 74 rubles per euro and 67 rubles per dollar, FxPro analysts say.According to the results of the main session on Wednesday, the euro was already close to 74 rubles, having tested the maximums of the month, the taking of which can finally drop the resistance of the ruble and rather quickly lead the pair to 76 rubles – the next level where a reversal to the decline was noted at the beginning of the year, according to FxPro .The dollar-ruble pair also traded close to this line – about 67 rubles per dollar. Taking this mark potentially opens the way for the pair to grow up to 70 rubles, since there are no significant levels of consolidation in the range of 67-70 rubles, according to FxPro. The history of the last five years shows that following an increase above 65 rubles, the dollar quickly reaches a level of 70, and only there can we expect any fierce struggle for the subsequent trend, analysts indicate.Trade wars remain an unsolved problem of the global economy, making the ruble and oil vulnerable, and also forming the basis for the further weakening of the Russian currency above 70 rubles per dollar and 77 rubles per euro at the end of the year. The possible escalation of trade disputes in the United States and China forces us to consider reaching potential levels as early as September in September, according to FxPro.According to the chief analyst of Promsvyazbank Mikhail Poddubsky, the current levels in the ruble can still be considered balanced. For most of August, its rate is in the range of 65-67 rubles per dollar, which is consistent with the fundamentally sound rate. At the same time, Poddubsky currently does not see any explicit internal drivers in support of the ruble – the current account in August is seasonally weak, the Ministry of Finance sets relatively low limits on OFZ auctions, the August tax period ended on the eve of paying income tax.
