MADRID | The Corner | The ruble plummeted on Monday, suffering its worst daily fall since Russia’s 1998 crisis, plunging more than 6% against the dollar before recovering to losses of around 4% Lowering oil prices are killing the currency, and yet Moscow does not intend to cut production in 2015, leaving output at the current 525-526 million metric tons. Russian analysts commenting for The Corner explained there is enough currency liquidity in the market to handle the shock. At least for now.
