Russia's fast track to ruin

Here are the numbers that explain why the Russian economy is imploding in the face of a tumbling oil price and Western sanctions.

Oil and gas energy represents two thirds of exports of around $530bn (£339bn). Without them, Russia would have a massive deficit on its trade and financial dealings with the rest of the world - which is why Russia's central bank expects a capital outflow of well over $100bn this year and next.

And public expenditure is almost completely supported by energy-related revenues. In their absence, the government would be increasing its indebtedness by more than 10% a year, according to IMF data.

So the massive and unsustainable non-oil deficits in the public sector and trade explain why investors don't want to touch the rouble with even the longest barge pole.http://www.bbc.com/news/business-30491170
