The 2008 Oil Price Spike

Cause 1: Demand from emerging economies

Between 2003 and 2008 the world economy grew fast, and almost all the growth in oil demand came from outside the OECD, led by China, India and the Middle East. Many of these countries subsidised fuel, so higher crude prices did not slow their consumption. In his 2009 Brookings paper, economist James Hamilton concluded that the 2007–08 run-up "was caused by strong demand confronting stagnating world production". Unlike earlier shocks, there was no large supply disruption.

Cause 2: Stagnant supply and thin spare capacity

World crude output barely grew from 2005 to 2008. Mature fields in the North Sea and Mexico were declining, and new projects were slow and expensive. OPEC's spare capacity, the market's shock absorber, was low. With little room to raise output, prices had to rise high enough to cut demand. This is the opposite of 1990, when ample spare capacity kept the Gulf War spike short.

Cause 3: The weak dollar

The US dollar fell steadily from 2002 to mid-2008, and the euro peaked near $1.60 in July 2008. Since oil is priced in dollars, a weaker dollar makes crude cheaper for buyers using other currencies and raises the dollar price that clears the market. Investors also bought commodities as a hedge against a falling dollar and inflation. See oil and the US dollar for how this relationship works.

Cause 4: Speculation and index investment

Money flowing into commodity index funds grew sharply in 2007–08, and critics argued in Congress that this had inflated prices. A US interagency task force led by the CFTC reported in July 2008 that supply and demand fundamentals explained most of the rise. Economists still debate how much financial flows added at the peak. Most research finds they amplified a move driven by fundamentals rather than causing it. Fund positioning is published weekly in the CFTC Commitments of Traders report.

The crash: July to December 2008

Demand was already weakening in mid-2008. US gasoline consumption fell as pump prices passed $4 a gallon. The collapse of Lehman Brothers on 15 September 2008 turned a slowdown into a global financial crisis. Credit for trade and inventories dried up, industrial output fell and funds sold commodities.

OPEC agreed a record 2.2 million barrels per day cut on 17 December 2008, but prices kept falling into the end of the year. The EIA spot price for WTI bottomed at $30.28 on 23 December, and Brent at $33.73 on 26 December. The futures curve moved into deep contango, and traders stored oil on tankers at sea because later delivery dates paid much more. Prices recovered through 2009 as OPEC cuts took effect and China's stimulus revived demand.

Economic consequences

Hamilton argued that the oil shock was a major factor in the US downturn, and that without it the period from late 2007 to the third quarter of 2008 would probably not have been classed as a recession. Lower consumer spending, especially on domestic cars, was the main channel. The shock also accelerated the shift towards fuel-efficient vehicles and made US shale drilling profitable, which led to the 2014–2016 crash.

Was $147 the real record?

In nominal terms, yes. $147.50 remains Brent's highest futures price, and in 2026 the EIA Brent spot price peaked at $138.21 (7 April). Adjusted for inflation, the July 2008 high equals about $225 per barrel in August 2026 dollars, the highest inflation-adjusted oil price of the modern era. Annual averages tell a different story. In real terms, 2011–2013 averaged more than 2008, because prices stayed above $100 for three years. See inflation-adjusted oil prices.
