That is a shift from the 1980s when Saudi Arabia had enough oil that it could affect the price of oil going up or coming down. Now, Saudi Arabia can only affect the supply of oil to result in increased price.
It turns out that Saudi Arabia's budget requires that oil stay at least above $83. This is what Saudi feels it requires to distribute enough money across the kingdom to prevent unrest being seen in much of the Mideast.
Many of OPEC’s biggest producers are using the price gains to increase public spending, partly to guard against popular unrest. Saudi Arabia announced a multiyear spending package of $129bn and is expected to spend about $35bn in 2011.$83. That's an important number to remember. Some time ago, EOG said the Bakken was "robust" at $40/bbl of oil Based on the current delta, Brent $83 oil translates into about WTI $73 oil.
This largesse means the country now needs an oil price of $83 per barrel in order to balance its national budget this year. “The more they earn, the more they tend to spend. So the oil price they need is ratcheted up,” said Leonidas Drollas, chief economist at the Centre for Global Energy Studies in London.
