Until the end of the year 2014, the US Dollar to Ruble exchange rate could be very well estimated by a simple linear regression model using the price of oil and the price of oil squared. However in the months since December of 2014, this simple model has been unable to capture all of the variability or trend of the USDRUB exchange rate. The purpose of this study is to explain behavior of the USDRUB exchange rate in the period since December of 2014 till present day i.e. till April 27, 2015.
