The ruble may fall in price on Monday due to the sociability of Donald trump, writes the Moscow Komsomolets.At the end of last week, the head of the US Federal Reserve Jerome Powell during a symposium in Jackson Hole did not give a clear signal about whether or not to reduce the rate. The president reacted to this with a question on Twitter whether Powell is a bigger enemy of America than China.Trump himself posed the fact that the previously announced 10 percent increase in duties on a number of goods would be 15 percent, and also warned that duties on a number of other goods would increase by 30%, not 25%, from October 1.For these reasons, the Dow Jones Index dipped 2.37% on Friday, the S&P 500 added 2.59%, the NASDAQ 3%, and the ruble fell to 66 per dollar.The G7 Summit kicked off this weekend in Biarritz. There, the American leader regretted that he did not increase duties even more, and, as the media write, he quarreled with the leaders of other countries of the Big Seven over the return of Russia to the G7 – he wants this himself, they do not.For this reason, the Japanese Nikkei 225 index fell 2% this morning, while Brent crude is cheaper by more than 1%. All this creates a negative background for the ruble. Today, in addition, the second package of US sanctions against Russia comes into force in connection with the poisoning of the spy Sergei Skripal.
