The Russian rouble is among the worst-performing currencies this year, shedding nearly 40 percent of its value against the U.S. dollar year to date.
The recent slump in energy markets could signal more losses ahead, following central bank governor Elvira Nabiullina's decision last month to tie the rouble's fortunes to the price of oil. Fuel prices have been in a downtrend since June, losing nearly 50 percent of their value, on the back of a price war waged by OPEC (the Organization of Petroleum Exporting Countries) against the U.S. shale producers and as demand from China decreased amid slowing growth.
Meanwhile, Ukraine's hryvnia has dropped nearly 80 percent against the greenback this year, to trade at 15,7085 per $1 on Monday, off last month's all-time low of 15,8817, weighed by tensions between government forces and rebels in the country's eastern regions.
After plunging to a record low of 15.95 to the U.S. dollar on September 25, the Argentine peso clawed its way back to 8.5525 on Monday as a crackdown on trading, a bond sale and a currency swap with China curbed transactions in both the legal and underground currency markets.
