 Investment banks, including Goldman, have also been accused of driving up the price of gasoline by speculating on the oil futures exchange.In August 2011, "confidential documents" were leaked "detailing the positions" in the oil futures market of several investment banks, including Goldman Sachs, Morgan Stanley, JPMorgan Chase, Deutsche Bank, and Barclays, just before the peak in gasoline prices in the summer of 2008.The presence of positions by investment banks on the market was significant for the fact that the banks have deep pockets, and so the means to significantly sway prices, and unlike traditional market participants, neither produced oil nor ever took physical possession of actual barrels of oil they bought and sold.
