So the real âcurseâ is in fact an oil price collapse. The current price collapse â for the first time since 2009 prices are below the symbolic $50 a barrel â is largely a result of the boom in shale oil production in the US, adding more than 3m barrels over the past few years. High prices bring investment and supply, and this boom was no different.
From 1999 til mid 2008, the price of oil rose significantly. It was explained by the rising oil demand in countries like China and India. In the middle of the financial crisis of 2007â2008, the price of oil underwent a significant decrease after the record peak of US$147.27 it reached on July 11, 2008. On December 23, 2008, WTI crude oil spot price fell to US$30.28 a barrel, the lowest since the financial crisis of 2007â2010 began.
