London gold fix study shows signs of decade of manipulation by bullion banks
By Liam Vaughn
Thursday, February 27, 2014
The London gold fix, the benchmark used by miners, jewelers, and central banks to value the metal, may have been manipulated for a decade by the banks setting it, researchers say.
Unusual trading patterns around 3 p.m. in London, when the so-called afternoon fix is set on a private conference call between five of the biggest gold dealers, are a sign of collusive behavior and should be investigated, New York University's Stern School of Business Professor Rosa Abrantes-Metz and Albert Metz, a managing director at Moody's Investors Service, wrote in a draft research paper.
"The structure of the benchmark is certainly conducive to collusion and manipulation, and the empirical data are consistent with price artificiality," they say in the report, which hasn't yet been submitted for publication. "It is likely that co-operation between participants may be occurring."
The paper is the first to raise the possibility that the five banks overseeing the century-old rate -- Barclays Plc, Deutsche Bank AG, Bank of Nova Scotia, HSBC Holdings Plc, and Societe Generale SA -- may have been actively working together to manipulate the benchmark.

It also adds to pressure on the firms to overhaul the way the rate is calculated. Authorities around the world, already investigating the manipulation of benchmarks from interest rates to foreign exchange, are examining the $20 trillion gold market for signs of wrongdoing.

Jim Sinclair plans seminars in Los Angeles and San Diego
Gold advocate Jim Sinclair's next market analysis seminars will be held in Los Angeles from 11 a.m. to 2 p.m. on Saturday, March 8, and in San Diego from 2 to 6 p.m. the following day, Sunday, March 9. Details, including registration information, are posted at Sinclair's Internet site, JSMinset.com, here:
Officials at London Gold Market Fixing Ltd., the company owned by the banks that administer the rate, referred requests for comment to Societe Generale, which holds the rotating chairmanship of the group. Officials at Barclays, Deutsche Bank, HSBC, and Societe Generale declined to comment on the report and the future of the benchmark. Joe Konecny, a spokesman for Bank of Nova Scotia, didn't respond to requests for comment.
... Union Jacks
Abrantes-Metz advises the European Union and the International Organization of Securities Commissions on financial benchmarks. Her 2008 paper "Libor Manipulation?" helped uncover the rigging of the London interbank offered rate, which has led financial firms including Barclays Plc and UBS AG to be fined about $6 billion in total. She is a paid expert witness to lawyers helping companies and individuals sue banks. Metz heads credit policy research at ratings company Moody's.
The rate-setting ritual dates back to 1919. Dealers in the early years met in a wood-paneled room in Rothschild's office in the City of London and raised little Union Jacks to indicate interest. Now the fix is calculated twice a day on telephone conferences at 10:30 a.m. and 3 p.m. London time. The calls usually last 10 minutes, though they can run more than an hour.
... Unregulated Process
Firms declare how many bars of gold they want to buy or sell at the current spot price, based on orders from clients and themselves. The price is increased or reduced until the buy and sell amounts are within 50 bars, or about 620 kilograms, of each other, at which point the fix is set.
Traders relay shifts in supply and demand to clients during the call and take fresh orders to buy or sell as the price changes, according to the website of London Gold Market Fixing, where the results are published. The fixing process is unregulated and the five banks can trade gold and its derivatives throughout the call.
Bloomberg News reported in November concerns among traders and economists that the fixing banks and their clients had an unfair advantage because information gleaned from the calls provided an insight into the future direction of prices and banks can bet on spot and derivatives markets during the call.
... All Down
Abrantes-Metz and Metz screened intraday trading in the spot gold market from 2001 to 2013 for sudden, unexplained moves that may indicate illegal behavior. From 2004 they observed frequent spikes in spot gold prices during the afternoon call. The moves weren't replicated during the morning call and hadn't happened before 2004, they found.
Large price moves during the afternoon call were also overwhelmingly in the same direction: down. On days when the authors identified large price moves during the fix, they were downwards at least two-thirds of the time in six different years between 2004 and 2013. In 2010, large moves during the fix were negative 92 percent of the time, the authors found.
There's no obvious explanation as to why the patterns began in 2004, why they were more prevalent in the afternoon fixing, and why price moves tended to be downwards, Abrantes-Metz said in a telephone interview this week.
"This is a first attempt to uncover potentially manipulative behavior and the results are concerning," she said. "It's down to regulators to establish why there are such striking patterns but banks have the means, motive and opportunity to manipulate the fixing. The results are consistent with the possibility of collusion."
... BaFin, FCA
Deutsche Bank, Germany's largest lender, said in January that it will withdraw from the panels setting the gold and silver fixings. German financial markets regulator Bafin interviewed the Frankfurt-based bank's employees as part of a probe into the potential manipulation of gold and silver prices.
"In general, research that finds certain price patterns does not as such constitute evidence of manipulation," said Thorsten Polleit, chief economist at Frankfurt-based precious-metals broker Degussa Goldhandel GmbH and a former Barclays economist. "However, it might encourage interest in finding out more about the sources of these price patterns."
The five banks that oversee the fixing set up a steering committee and will appoint external advisers to consider reforms before EU legislation on financial benchmarks' regulation and oversight comes into force, Bloomberg reported last month.
Britain's Financial Conduct Authority is also scrutinizing how prices are calculated. The regulator published a report this week outlining its remit for regulating commodities including gold, saying that while it's responsible for commodities derivatives, it doesn't regulate physical commodities.
"Abusive behavior can occur in the physical commodity markets which in turn can have an impact on, or be directly linked with, financial market activity and prices," the FCA said in the report. "The regulatory regime -- both in the U.K. and internationally -- needs to be adapted to ensure robust and appropriate oversight."
