The Iranian Oil Bourse (), International Oil Bourse, Iran Petroleum Exchange Kish Exchange or Oil Bourse in Kish (IOB; the official English language name is unclear) also known as Iran Crude Oil Exchange, is a commodity exchange, which opened its first phase on 17 February 2008. It was created by cooperation between Iranian ministries, the Iran Mercantile Exchange and other state and private institutions in 2005. The history of Iran Mercantile Exchange and its links with the "international trading floor of crude oil and petrochemical products in the Kish Island" (IOB) have been published. The IOB is intended as an oil bourse for petroleum, petrochemicals and gas in various currencies other than the United States dollar, primarily the euro and Iranian rial and a basket of other major (non-US) currencies. The geographical location is at the Persian Gulf island of Kish which is designated by Iran as a free trade zone. During 2007, Iran asked its petroleum customers to pay in non US dollar currencies. By December 8, 2007, Iran reported to have converted all of its oil export payments to non-dollar currencies. The Kish Bourse was officially opened in a videoconference ceremony on 17 February 2008, despite last minute disruptions to the internet services to the Persian Gulf regions. Currently the Kish Bourse is only trading in oil-derived products, generally those used as feedstock for the plastics and pharmaceutical industries. However, officially published statements by Iranian oil minister Gholam-Hossein Nozari indicate that the second phase, to establish trading in crude oil directly, which has been suggested might one day perhaps create a "Caspian Crude" benchmark price analogous to Brent Crude or WTI will only be started after the Bourse has demonstrated a reasonable period of trouble-free running. Due to technical problems, the oil bourse never proceeded, and the plans were finally abandoned after a vote by the Iranian Parliament on 7 January 2020. Background The three current oil markers are all US dollar denominated: North America's West Texas Intermediate crude (WTI), North Sea Brent Crude, and the UAE Dubai Crude. The two major oil bourses are the New York Mercantile Exchange (NYMEX) in New York City, and the IntercontinentalExchange (ICE) in London and Atlanta. As the Oil Bourse in Kish is developed through successive stages, the plan is to establish a Petrobourse as a fourth oil market, denominated by the Iranian rial, the euro and other major currencies.
