"For the dollar, the key support is in the range of 85-86 rubles, for the euro - 94-95 rubles. The fundamental factors in favor of the ruble are still strict control over the mandatory sale of export earnings, a fairly tight monetary policy of the Bank of Russia, and the general weakness of the US dollar on global platforms," the expert explained.

In addition, according to him, the peak of tax payments falls on November 28.

"Therefore, if oil prices stabilize and the dollar continues to weaken, the ruble may well approach these levels by December 1. The first signs of the beginning of a correction in the ruble against the dollar will appear if the closure is above 89.2 rubles. And an exit beyond 90.5 rubles will form a bullish impulse for the dollar. Since the beginning of autumn, the dollar exchange rate has fallen by 7.69% from 96.03 to 88.63 rubles. The euro fell by 8% from 104.09 to 96.71 rubles. The trend of ruble appreciation will last at least until the beginning of winter," the RT interlocutor predicted.

Earlier, Antonov commented in an interview with RT on the data, according to which the dollar exchange rate fell below 88 rubles during trading on the Moscow Exchange.
