A plan appears to have been put in place by the U.S. and the European Union countries to strengthen the American position in negotiations with Iran underway in Istanbul. The impact on oil prices and on U.S. and E.U. growth as a consequence of higher oil prices, especially when the eurozone countries faced lowed growth, was one of the ways Iran hope to blunt the tightening of sanctions against Iran's nuclear program.

At the same time a similiar effort was being implemented to increase production in Iraq and Libya so that it would add to reserves added by the Saudis. Daily output from OPEC countries increased by about 1.4 millon barrels in the Sept 2011- March 2012 period, as the confrontation with Iran took shape with increasing pressure using sanctions on Iranian oil, according to the IEA. Of this 1.4 million barrels a day increase, one third is from the Saudis and the rest from Iraq and Libya, according to IEA. In March 2012, OPEC oil production increased by 135,000 barrels a day to 31.4 million barrels, mostly from higher output in Iraq. The Saudis have filled up domestic oil inventories and placed an additional 10 million barrels of oil in storage close to markets in Europe and Japan. This suggests that this was part of a quietly implemented plan in cooperation with the U.S. and the EU countries to increase the effectiveness of sanctions and protect global oil supplies from disruptions; even as the U.S. pressured Japan, S. Korea, India and other countries to reduce purchases of Iranian oil. The economies of India, the EU and other countries were already beginning to feel the impact of higher oil prices in the 1st quarter of 2012....
