Russia's battered ruble sank Monday to its lowest point this year as Asian and European stock markets nosedived on concerns over the Chinese economy.
Russia's dollar-denominated RTS stock index had plunged nearly 4.5 percent by 1100 GMT as the ruble tumbled to 70.92 against the dollar, its weakest since December 2014.

Russia's currency has fallen more than 20 percent against the dollar in the past two months, sparking fears of more instability after a period of relative recovery.

The ruble lost around half of its value in 2014 but recovered slightly as energy prices stabilised this year, allowing officials to claim the worst of the crisis had passed.

"The ruble's value is most of all influenced by oil prices," RBK business daily quoted Alexander Muhlberger, a director at BCS financial group, as saying.
"If oil prices keep declining, then it's clear what the ruble's trajectory will be."
Economy Minister Alexei Ulyukayev said he expected oil prices to briefly drop below $40 a barrel, Russian news agencies reported.
