"The fall in GDP of Ukraine in 2014 will amount to 7.5%, amid the halving of the value of the national currency," Gontareva said.

Gontareva also said the NBU provided state oil and gas company Naftogaz Ukrainy with $8.6 billion from reserves in 2014, and she predicted a rise in inflation due to higher bills for gas.

"Inflation may be at 17-18% next year, as tariffs will be driven up to a market level," she said.
