Crude oil prices have a major influence on the fuel price for the consumer, indeed in the United States, crude oil constitutes 69% of the price of a gallon of regular gasoline (where refining only costs 9%, distribution and marketing 8%, and taxes 14%).7 Gas prices are more complex, since there exist three regional gas markets (North America, Europe and Asia) with strong historical relations due to the pipeline infrastructure on these continents. At the same time, a new type of gas transportation is rapidly accelerating: liquefied natural gas (LNG), which can be shipped over long distances albeit only with specially equipped tankers since it requires constant cooling at minus 162°C. Usually, the long-term price of gas is indexed to oil product prices, and consequently follows its volatility.
