The loss of oil revenues ? a drop of as much as 60 percent, according to a 2017 Congressional Research Service report ? helped spark a collapse in Russia's currency, the ruble, sending the prices of Russian consumer goods soaring.
The Russian economy has also been hurt by a wave of capital flight out of the country, as individual Russians sought to move money offshore and convert their shrinking rubles to dollars and euros to protect their wealth. That money flow slowed in 2014 as U.S. and European sanctions took hold.
Though U.S. sanctions have put pressure on the Russian economy, the impact on American business has been limited because Russia makes up less than 1 percent of U.S. exports.
Only six U.S states count Russia as a significant market for goods and services. Washington, the most reliant, sells roughly 1 percent of its total exports to Russia, consisting mostly of machinery and farm products. That's half the level before the 2014 sanctions took effect.
European nations, which export greater volumes to Russia than the U.S., imposed their own set of sanctions response to the Crimean annexation.
