Saudi Arabia, the world's largest oil producer, needs to sell oil at around $106 to balance its budget, according to IMF estimates. The kingdom barely has enough fiscal buffers to survive five years of $50 oil, the IMF said. That's why Saudi Arabia is moving fast to preserve cash. The kingdom not only raised $4 billion by selling bonds earlier this year, but its central bank has yanked up to $70 billion from asset management firms like BlackRock (BLK) over the past six months. The Saudi's started all of this and but do they know exactly what they are doing?
