World Nominal Oil Price Chronology: 1970-2006
The price data graphed above are in nominal terms, i.e., they are

Clicking the picture above will enable you to access oil prices in real

inflation. Historical and forecast real and nominal crude oil and
gasoline price information is maintained on a more frequent basis on
Short Term Energy Outlook Webpage.

rise as Iraq's refusal to allow United Nations weapons inspectors into

56.World oil supply increases by 2.25 million barrels per day in 1997, the largest annual increase since 1988.
prices continue to plummet as increased production from Iraq coincides

Total pledged cuts amount to about 4.3 million barrels per day.
prices triple between January 1999 and September 2000 due to strong

Clinton authorizes the release of 30 million barrels of oil from the

particularly heating oil in the Northeast.
prices fall due to weak world demand (largely as a result of
economic recession in the United States) and OPEC overproduction.
prices decline sharply following the September 11, 2001 terrorist
attacks on the United States, largely on increased fears of a sharper

oil supply disruptions in Iraq and Nigeria, as well as strong energy
demand, raise prices during the first and second quarters of 2005.
