Russia's ruble currency fell to a record low versus the US dollar on 20 January as prices for the country's main export, oil, continued to tumble. The ruble slipped past the mark of 80.1 per US dollar in intraday trading, surpassing the previous record set in December 2014, according to a post on the Moscow Exchange bourse's website. Falling oil prices have the potential to jeopardize Russia's stability by severely weakening its economy. EPA/YURI KOCHETKOV
