The Consortium Agreement of 1954 (Persian: قرارداد کنسرسیوم) provided Western oil companies with 50% ownership of Iranian oil production after its ratification in 1954 expiring in 1979.[1] According to the consortium agreement, 40% of Iran's oil shares belonged to 5 American companies, the other 40% belonged to Iran-UK oil companies, 14% belonged to a Dutch oil company, and the remaining 6% belonged to a French oil company.[2] In spite of numerous negotiations and offers, Mohammad Reza Shah refused to extend the Agreement which originally and clearly postulated that the Consortium had the right to prolong it 15 years (3 times 5 years).
A year after the overthrow of Premier Mohammad Mossadegh by the United States and the United Kingdom in the 1953 Iranian coup d'état, the British and American governments began pressuring the reinstated Shah of Iran into negotiations with Britain over the ownership of the Anglo-Persian Oil Company. The British cabinet had imposed a series of economic sanctions on Iran that prohibited the export of key commodities to Iran.[3] Britain's boycott had become devastatingly effective, with Iranians "becoming poorer and unhappier by the day".[4
The dispute was finalized with the incorporation of a 25-year international Oil Consortium Agreement of 1954, dividing the aforementioned 50% ownership to foreign companies as follows. 40% to be divided equally (8% each) among the five major American companies; British Petroleum to have a 40% share; Royal Dutch/Shell to have 14%; and Compagnie française des pétroles, a French Company, to receive 6%. A year later in 1955 US-government ordered the 5 US-companies to each transfer 1% of their 8%, to several smaller companies because these companies had complained that 'they were left out'.[5]
The agreement further stipulates that the Consortium would take care of
(almost) all production,
Refining,
transport and
(only international) marketing
of Iranian oil for which purposes two Dutch legal entities were to be created and based in The Netherlands:
Iranian Oil Refining Company
Iranian Oil Exploration and Producing Company.
Basing these companies in Great Britain was considered politically undesirable, as was the initial wish of BP to get 50%. With English companies and a large 50% stake, was thought not to be acceptable to the Iranians. Furthermore, 50% would materially give BP a majority stake because BP had strong connections with the little (6%) French company CFP. Hence only 40% for the former 100% possessor.
The agreement, which was heavily pressured by President Eisenhower, gave American oil companies significant influence over how much petroleum Iran pumped and the price it could sell for.[6] Beginning in 1973, the Shah faced increasing tensions with Western nations after announcing he would not renew the consortium agreement upon its expiration and planned to nationalize Iranian oil in 1979. The Shah, speaking to 5,000 farmers and workers, accused the oil companies of mishandling operations under the 1954 agreement. He said he had ordered the National Iranian Oil Company to start hiring foreign experts to work with Iranians so the company could take over the consortium's duties “either immediately or from 1979.”[5]
Many Iranians accuse Western nations of supporting the overthrow of the Shah due to his failure to renew the consortium agreement in 1979 in what is known as the 1979 Iranian Revolution conspiracy theory.[7] According to the New York Times, the oil companies, through a spokesman, argued that the Shah did not have a legal right to end their contract in 1979, because the Consortium had the right of prolonging it for 15 years.
