Wall Street Banks in Commodities Businesses: An Inherently Unethical Conflict of Interest

Writing to the bank’s board of directors, an executive at Goldman Sachs wrote that the bank’s commodities division would achieve higher value “if the business was able to grow physical activities, unconstrained by regulation and integrated with the financial activities.”[1] According to Sen. Carl Levin, Goldman’s goal here is “to profit in its financial activities using the information it gains in the physical commodities business.”[2] The integration could be achieved in part by using the bank’s access to nonpublic information from the banking or trading operations to manipulate the price of a commodity by artificially restricting or adding to supplies through ownership at the production or storage stages. This structure contains a conflict of interest. Because resisting the temptation to exploit the conflict would put the Goldman bankers at odds with the bank’s financial interest, I contend that reliance by the public on intra-bank firewalls (i.e., policies) separating the commodity businesses from the bank’s trading operations is too weak to protect the public, including buyers of the commodity.
