The Finance Ministry said it did not channel money from the Reserve Fund to balance the federal budget in October largely due to high oil prices, with Russia's Urals oil blend hitting a historic high of $72.5 per barrel for 2009.
As of October 1, the Finance Ministry channeled a total of $67 billion from the Reserve Fund to balance the federal budget, including $10.3 billion in September.
In line with budget policy guidelines for 2010-2012 approved by the government in July, a total of $95.5 billion, or 7.9% of the country's GDP, will be spent on covering the budget deficit this year.
Russia's Reserve Fund is expected to fall to $50 billion by the end of the year and run out entirely in 2010, while the National Welfare Fund will fall to $91 billion by the end of the year and down to $3 billion by the end of 2012.
