The Russian Ruble is represented on an inverted, logarithmic scale vs.the G/S & G7 currency basket, where a rise in price levels on the chart indicates an irise in the Ruble.
For all the widely known reasons the Russian Ruble remains a remarkably accurate yard stick of the march of imperialism and the states of various hegemonies ("Globalization", in short) for the past 20 years.
The Russian Federation maintains 0 (zero) debt, a positive account balance, combined with what is most likely the largest horde of gold & foreign reserves outside (and insulated from) Western jurisdictions, making the currency remarkably stable - despite all the propaganda and wishful thinking to the contrary -, for the past two decades. (It has proven itself far more stable than other means or stores of value across the G-7. This is clearly a thorn in the side of others' continued imperialist aspirations.)
These facts simply highlight the present (and potential future) opportunity, wherein any significant deviation from the Median likely represents a significant trading opportunity.

p.s. On the contrary, the current vogue of wide spread and simple-minded speculations, heralding the rise of China and hence, the Yuan/Remninbi as the new, potentially global reserve currency, are so fundamentally flawed that entire books have addressed the topic as of late, examining it in great detail and with accuracy. I.e., a rapidly collapsing Chinese population, quickly followed by de-industralization and de-urbanization a stable, global reserve currency does not make! - Among other, inherently disqualifying factors.
