The Globe and Mail reports in its Wednesday, Feb. 25, edition that unnamed sources say United States officials are investigating at least 10 major banks for possible rigging of precious-metals markets. A Dow Jones dispatch to The Globe reports that sources say the U.S. Justice Department's antitrust division is scrutinizing the price-setting process for gold, silver, platinum and palladium in London, while the Commodity Futures Trading Commission has opened a civil investigation. The agencies have made requests for information, including a subpoena from the CFTC to HSBC Holdings related to precious-metals trading. HSBC also said the Justice Department sought documents related to the antitrust investigation in November. The two probes "are at an early stage," the bank added, saying it is co-operating with U.S. regulators. Also under scrutiny are Bank of Nova Scotia, Barclays, Credit Suisse Group, Deutsche Bank, Goldman Sachs Group, J.P. Morgan Chase & Co., Societe Generale, Standard Bank Group and UBS, sources say. The precious-metals probes are the latest example of regulatory scrutiny into how the world's biggest financial institutions influence widely used benchmarks.
