Russia will seek to balance its budget by 2015, based on oil at $70 per barrel, Finance Minister Alexei Kudrin said Tuesday, signaling that new strategies will be needed as the country struggles to erase its first deficit in years.

As commodity prices plunged in the wake of the financial crisis, Russia's economy ground to a near halt, forcing the country to spend billions propping up state companies in order to stave off unemployment and public unrest.

But while Prime Minister Vladimir Putin has called for the deficit to be cut from up to 5.4% of gross domestic product--around $77 billion--this year to zero in 2015, economists question whether this is possible, especially with the government looking to spend big to help growth and ease social tensions ahead of 2012 presidential elections.

"Our goal is to gradually get to a level where the budget is balanced at $70 per barrel. This means we need to cut costs, cut the deficit," Kudrin said. "By 2015, we can easily do this without changing our social obligations."

Last year's budget would have been balanced at the price of $98 per barrel for oil--Russia's chief export and the main driver of its economy. To get that number down to $70 per barrel would entail huge cuts in spending, analysts said.

"Kudrin's plan is achievable, but there would have to be more efficient spending, and not simply less spending," said Yevgeny Gavrilenkov, chief economist at Troika Dialog. "And of course, there would have to be cuts."

This year's budget has already been amended twice to allow for increased spending in 2011. Further increases may come in the form of more spending on everything from pensions--which were already increased by 45% this year and may be hiked further in 2011--to the 2014 Winter Olympics, taking place in the city of Sochi with an estimated price tag of $14 billion.

One place the government should look to cut costs would be in its support of lumbering state-run giants like Avtovaz, which received a $1.3 billion state bailout package last year and will likely need support well into the next decade, Gavrilenkov said. "Most of that money goes into a black hole."

Putin however, has dismissed that idea, saying last week that he saw the de-industrialization of the country as a dead end and pledged support for the aviation and automotive sectors, which are slated to receive a combined $12 billion in state support between 2009 and 2011.
