Col. Muammar el-Qaddafi has stashed billions of dollars of Libyan oil revenues with financial institutions on Wall Street and in Europe, according to a document made public Thursday by an international advocacy group. Goldman Sachs, JP Morgan, HSBC Holdings and Société Générale are among the major banks that have helped the strongman to invest some of the Libyan sovereign wealth fund’s $53 billion, according to the document, which was published on the Web by Global Witness.

The fund also invested billions of dollars in the stocks of well-known companies, including General Electric, Halliburton, BP and Nokia, and held a large portfolio of United States government bonds.
