Solomon and Said give a detailed account of the events leading to the steep decline in oil prices to $61 a barrel by December 2014. The steep declines have caused a shock for OPEC and non-OPEC producers. A price decline of this magnitude may not have been anticipated by the Saudis, and there are divisions among Saudi officials and in the royal family about whether such steep cuts are best for Saudi Arabia. The price per barrel of oil for each OPEC country to balance its budget varies widely, according to IMF and IEA, WSJ, sources. For Saudi Arabia this estimate is $106, Iraq 101, for Russia $98. The Saudis have $750 billion in foreign currency reserves. At the high end are Libya at $184, Iran at $131, Algeria $131, Nigeria $122, Venezuela $117. The UAE is at $77, Qatar $60. Norway is at the low end at $40. On Dec. 19, 2014 the price of Brent crude, ICE for Jan. delivery was $61.38.
