Question

Calculate the percentage change in the value of the ruble for the two different cross rates shown in the table for the five periods. Did the ruble fall further against the U.S. dollar or the Swiss​ franc?

Switzerland has long served as a cornerstone of banking conservatism and a safe port in a world of currency storms. Swiss banks had long been used by investors from all over the world as financially secure institutions that would preserve the​ depositor's wealth with confidentiality. A large part of the security offered was the Swiss franc itself. Russian citizens of wealth had used Swiss banks heavily in recent years as a place where they could shelter their capital from​ politics, both inside Russia and the outside​ (EU and​ US) world. But beginning in the fall of 2014 the Russian​ ruble's value began to slide against the Swiss​ franc, threatening their wealth.
