The shocking collapse of the price of oil has hit a lot of countries really hard, but very few nations are as dependent on energy production as Russia is.  Sales of oil and natural gas account for approximately two-thirds of all Russian exports and approximately 50 percent of all government revenue. So it should be no surprise that the fact that the price of oil has declined by almost 50 percent since June is absolutely catastrophic for the Russian economy.  And when you throw in international sanctions, wild money printing by the Central Bank of Russia and unprecedented capital flight, you get the ingredients for an almost perfect storm.
