Russia's central bank said on Thursday it had shifted the boundaries of the rouble's trading band by 25 kopecks the previous day, following market interventions to curb the pace of the currency's decline.
"The future prospects for the rouble will be determined by oil prices, and only their stabilization combined with growing sales (of foreign currency) from exporters ahead of the tax period could strengthen a corrective trend," Dmitry Polevoy, an ING Bank economist in Moscow, said in a note.
Greek stocks, which suffered their biggest one-day loss since the height of the euro crisis on Wednesday due to concerns about possible early elections and Athens' plans to wean itself off international aid, continued to fall on Thursday although less sharply. They were down more than 1 percent, adding to an 11.5 percent slide over the previous two days.
Weaker oil prices are also weighing on African sovereign debt, with Nigeria's 2023 U.S. dollar denominated bonds marginally lower. Ghana's 2023 bond was harder hit, dropping 0.125 of a cent.
Ghana cut its economic growth forecast slightly for this year, to 6.9 percent, on Wednesday as it grapples with inflation and a sharp fall in its currency. The government is in talks with the International Monetary Fund on a possible financial assistance program that could begin in January.
