Moscow: Russia's RTS stock index dived more than 10 percent on opening Tuesday after a public holiday, following a crash in oil prices that saw the ruble and global markets post massive losses.

The dollar-denominated RTS index fell 16 percent on opening before rallying slightly to be around 13 percent down at 0815 GMT.

The ruble-denominated Moex fell 10.4 percent on opening before recovering slightly to show a loss of 8.5 percent.

The Russian ruble tumbled in value Monday to trade at 75 to the US dollar, a rate last seen in early 2016.—AFP
