FX Manipulation Lawsuit Tsunami at Banks' Doorstep

First, about three weeks ago, JPMorgan settled an FX manipulation lawsuit for a reported $100 million. Now, Reuters reports that a judge allowed the investor plaintiffs' case to go forward to trial over the banks' objections. These included that there was a lack of evidence and that a prior LIBOR case alleging antitrust abuses was thrown out of court.

These two events alone should bring forth a barrage of suits as success seems more probable. In addition, now that this trial can go forward, the banks' position looks to be hurt by two factors.

First, depositions can now be taken, which may provide additional evidence of wrongdoing (several of the banks have already been fined by regulators following employee interviews). Second, a problem in suing to date has been attempting to prove wrongdoing and antitrust behavior. There is a lack of data on trades executed by banks on specific dates in specific currencies. Trade data released by banks during the discovery process may make the plaintiffs' calculation of any damages much easier, rather than relying upon models of what may have been manipulation based solely upon price movements.

While lawsuits from investors (money managers, pensions funds, etc.)and corporations are to be expected, many other groups impacted by currency rates can be expected as well. As an example,a few weeks ago we reported on British farmers that may have been affected by the conversion of subsidies from euro to British pounds.

FSB Proposes FX Benchmark Changes; UK Opens Criminal FX Benchmark Investigation

The Financial Stability Board (coordinates national regulators and international standard setting bodies)  published suggested changes to FX benchmark calculations in the following areas:

  • The calculation methodology of the WM/Reuters (WMR) benchmark rates;
  • The publication of reference rates by central banks;
  • Market infrastructure in relation to the execution of fix trades;
  • The behaviour of market participants around the time of the major FX benchmarks (primarily the WMR 4pm London fix);
  • Recommendations from a forthcoming IOSCO review of the WMR fixes.
These are open to comments and should entail great diversity as there is much disagreement on how to reduce the possibility of rate rigging in FX markets.

In the UK, the Serious Fraud Office (SFO) has opened a criminal investigation into possible fraud occurring in benchmark rate setting.  The US DOJ has been looking into criminal angles for quite some time,and last week we reported their offer of immunity to junior FX traders in exchange for information. The SFO has an ongoing investigation into LIBOR rigging as well.

UK's FCA Benchmark Manipulation Investigations - Let's Hope the Tortoise Wins the Race

Reuters reports the Financial Conduct Authority's head of markets infrastructure and policy testified before a Parliment committee on their benchmark investigations.  None of his comments indicated that the investigations were moving very quickly.  

On the possibility of collusion in setting the London gold fix the FCA stated "It is possible but I have no clear evidence that that has actually happened".  The FCA fined Barclay's in May for a trader manipulating the rate in 2012 to avoid paying off on a client gold contract.  Next month the industry is to report on whether the process meets new benchmark guidelines.  

The FCA could provide the committee with no guidance as to when the FX benchmark investigation, which began a year ago, will reach a conclusion.  

A committee member claimed that it is well known by equity traders around the world that closing stock prices are also manipulated.  The comment from the FCA involved checking back to see if any action has been taken in this area.  While we are not familiar with charges of equity price manipulation either, the incentive to do so is clear, as portfolios are valued using those levels.

All in all, the FCA gives the appearance of moving deliberately, and since these are complex charges, with huge amounts of data and conversations to review, the slow pace appears inevitable. More important than the timing, at the conclusion of these benchmark investigations, market participants' faith in the markets must be restored.

Deutsche Reported to Set Aside $2.7 Billion in FX Legal Costs and Fines

Last week Deutsche announced that in total, it is facing 1,000 lawsuits with potential payouts above 100,000 euros. We reported here last week that Bafin, the German regulator, announced that the FX benchmark probe was "much, much bigger" than the LIBOR case.  Now Reuters reports that sources tell it that Deutsche is setting aside $2.7 billion to cover future FX fines and settlements.

Put these together and, while it is not certain what has been found so far in the internal and various regulatory investigations, Deutsche clearly believes that there will be substantial costs going forward of at least that amount.  Of course, this does not necessarily mean that Deutsche believes that they are guilty as they may feel that they are meeting accounting/legal requirements in recognizing these costs at this time.  However, throw in several FX traders that Deutsche has suspended during its internal investigation, and it is difficult not to lean towards the view that where there is smoke there is fire.

Legal Theories in LIBOR and FX Lawsuits

While this article in CapLaw discusses the history of the allegations, investigations and lawsuits in the FX and LIBOR scandals, we thought it most interesting to focus on the legal theories and their current status.

In LIBOR, the US consolidated case held that there was no antitrust damage as the LIBOR rate setting process was not competitive in nature and thus there could not be anti-competitive behavior.  However, "second-generation" lawsuits filed by plaintiffs claiming direct trading losses from derivatives with banks that provided benchmark LIBOR rates, are moving through the legal system.  Two large plaintiffs are the FDIC, on behalf of 38 failed banks, claiming fraud and collusion were used by the LIBOR setting banks to suppress rates, and Freddie Mac and Fannie Mae, claiming that LIBOR manipulations caused them to suffer losses on mortgages and financial derivatives.

LIBOR cases in the UK have been limited, with only two cases filed, one of which was settled and the other remains with the courts.

In the FX benchmarks, the US has consolidated numerous class action suits into one.  Differences between the rate setting process in FX vs. LIBOR make it unclear whether antitrust charges will hold up in the FX case.  Fraud and collusion charges remain in FX as well, but the later start of FX allegations, the complexity of the cases and the continuing regulatory and internal bank investigations, means that further clarity will not be forthcoming until at least late 2014.

If FX Benchmarks were Manipulated, How Often did it Occur?

FX Week (subscription) reports that the counsel for one of the plaintiffs in the FX benchmark class action suit says that their analysis of London Close benchmark trades for the six most liquid pairs on the last day of the month for the past 10 years shows manipulation occurred between 26% and 34% of the time.  The headline of the article, however, is a bit misleading: FX benchmark manipulated more than 25% of the time, plaintiffs say.

Even if the interpretation of these results can be said to be true, this still would not mean that there was that much manipulation on all trading days.  The last day of the month was most likely reviewed because most asset managers that hedge the FX in their portfolios adjust the hedges on that day, leading to particularly high volumes.  These high volumes, and the tendency for these hedge adjustments to be in the same direction, would make those the days most likely for manipulation if there was any.

So even if you did accept the results, it does not answer the question of how extensive was any FX benchmark manipulation.

Who needs Flash Trading when we have the FX London Close?!

The hotly debated, headline story of the moment is whether some HFT (high-frequency trading) firms are front-running all other U.S. equity investors by paying fees to the exchanges.  Good question .... but let's look at another topic in the news:  allegations of front-running and collusion in the London Close for currency trading in the WM/Reuters index.

Quoting an earlier and detailed Financial Pests account:

"Many banks provide a service to their customers where they guarantee to trade for them at the London Close rates. Customers provide the trade amounts to their banks within the one hour prior to the London Close, also known as “the fix”.  Those banks that have agreed to make transactions for funds at the London Close need to push through the bulk of their trades during this window where possible to minimize losses from market movements."

Instead of several MILLISECONDS of potential front-running, the London Close provides ONE HOUR of potential front-running!

Focusing on the London Close, what strikes us is that there's an easy answer.  First and foremost, it's a risk management issue.  Banks and dealers should not "guarantee to trade for [clients] at the London Close rates."  It's simply not possible to achieve the last price whereas giving a "guarantee" of last price is a difficult-to-quantify risk exposure.  With both this quantification difficulty and the appearance of manipulating markets that arises from trading as much as possible in the final minute, prudent risk management dictates "don't offer the London Close guarantee trade to clients."

As an alternative to banning the London Close trade, permit the pairing of such trades for clients on opposite sides.  Prior to close, the client may commit itself to executing a stated maximum notional at the fix price subject only to the dealer finding a client for the other side.  If confirmed prior to the market close, this trade execution can be posted to the exchange for all participants to see.  If no client materializes for all or part of the stated notional, then the original client order is not completely filled.

Class Action FX Benchmark Lawsuit Filed

A dozen individual lawsuits alleging antitrust and anti-competitive behavior on the part of the 12 largest FX trading banks, based upon their behavior at the WM Reuters London Close FX fix, were consolidated and filed as a class action last week.  The plaintiffs and defendants are listed below.

The allegations are similar to those aired in the press over the last nine months or so.  This suit has updated some of the individual suits based upon recent information from the Bank of England and recently fired or suspended bank traders and include some examples of how FX rates were allegedly manipulated.  While for bank customers and those interested in the integrity of markets, the issue is simply whether or not the allegations are true, for the success of the suit, antitrust and anti-competitive behaviors must be shown.  Thus much of the suit contains the plaintiffs' building of such a case.  Similar issues drove the LIBOR case.

Much of the information for the case and press stories, relates to banks' internal investigations and their cooperation with regulators.  As highlighted in the suit, DOJ LIBOR non-prosecution and deferred prosecution agreements require many banks to provide information relating to benchmark manipulation, including manipulation of FX benchmark rates.

The class has been defined as those trading FX at or around the London Close since at least June 1, 2003. Included are those not trading the fix but trading at around that time of day and those trading forwards and swaps as well as spot.

No attempt is made to quantify damages or who are the members of the class.  Reference is made that records should exist, which we can only assume would be held by the banks.

Plaintiffs                                                                        Defendants
Aureus Currency Fund                                                     Bank of America

BOE Governor Testifies Tomorrow; Will need to Defend the Bank's Integrity Regarding the FX Fix

The BOE Governor will testify before the UK Parliment's Treasury Committee tomorrow to defend the BOE in the wake of meeting minutes showing that there was knowledge within the BOE as early as 2006 of unusual trading around the 4PM London fix for foreign currencies.  At this point the BOE says that it is unaware of any collusion between traders and BOE staff, however, there are many questions regarding specifically what the BOE was told and why this information was not passed up the chain of command.

Assuming that lack of collusion holds up under internal BOE investigation, the most likely explanation of why no action was taken may have to do with the age old problem of coziness between the regulator and the regulated.  Examples have repeatedly come to light among utilities (gas, electric and pipelines), banks, insurance companies and when closely regulated in the US many years ago, the trucking and airline industries.

EURIBOR Benchmark Reforms

The EURIBOR European Banking Federation (EURIBOR-EBF) manages short term interbank interest rate benchmarks within the EU.  The European Securities and Markets Authority (ESMA) and the European Banking Authority (EBA) released a report reviewing changes made by the EURIBOR-EBF, noting the progress made in "raising the transparency of the benchmark setting process, enhancing the governance and control mechanisms of the benchmark, thereby improving the quality and reliability of the resulting index".

Just as interest rate benchmark process changes have been and continue to be made, changes in FX benchmarks are on the way as well.  We reported earlier this week that Singapore has stopped publishing FX benchmarks for certain SE Asian currencies used for non-deliverable forwards (Singapore Ends FX Benchmark for Indonesian Currency).  It is unlikely that WM Reuters or other benchmark setters will wait for the results of investigations before changing their processes as press reports have raised market concerns which will need to be addressed as soon as practical.

FX Benchmark Investigations to Drag into 2015

An article in FX Week regarding the FCA investigation into the FX benchmark allegations quotes a defense attorney as saying that the findings would become public when the investigation nears its final stages, not before early 2015.  In the event of any disciplinary action, it is at this point that warning notices would be publicly issued.

The investigation complexity is driven by the large number of banks alleged to be involved, the wide ranging and voluminous documents expected to be handed over, and as well, the large number of people who will be interviewed.

There are investigations by several national and supranational regulators.  It is safe to assume that they will cooperate with each other and that none will be in a position to announce results in the near future.

A Third WM Reuters Fix Class Action Suit Filed; Deutsche Suspends Head of Emerging Markets FX Trader in NY


Courthouse News Services reports that a class action suit was filed by Five Star Forex alleging that Barclays, BNP Paribas, CitiBank and Credit Suisse conspired to fix the foreign currency exchange market through the manipulation of WM/Reuters Rates bought and sold in the US since 2003. The suit was filed in USDC Southern District of New York.  There have been at least two previous class action lawsuits filed, by A Haverhill, a Massachusetts pension fund and Simmtech, a South Korean corporation.

It was also reported today that Deutsche suspended this senior trader in mid-December.

The stories continue, but at this point neither of these sheds any more light on what actually happened. The filing of lawsuits is understandable, and possibly encouraged by the banks continued suspension and firing of employees related to internal bank investigations of the fix allegations.

WSJ - BOE Governor Carney: Regulators Must Fix Mechanics of Libor, Forex Benchmarks

"The" quote from the article: "While regulators will fix the mechanics of benchmarks in markets ranging from LIBOR to foreign exchange, only private individuals and institutions can reform the behavior that has made such changes necessary," Mr. Carney said.  
This quote confirms our belief in additional regulation to come. The article infers that this quote only refers to banks and traders, but we suggest that in the case of FX, it should also include asset managers who were requesting execution of their trades with no profit for the banks, at a benchmark rate to be determined.  Such a situation is fraught with peril.

Rate Manipulation News May Shake Investor Confidence in Markets

The news stream on alleged benchmark manipulations in different markets continues, including commodities, interest rates and FX.  While banks have only admitted wrongdoing in the LIBOR scandal, the news in just the past week has been widespread and includes:

1) Reports of firings and suspensions have been increasing in frequency, to include 2       employees suspended at each Citi and HSBC just this past Friday. 
2) Deutsche Bank is withdrawing from the London Gold fix.
3) German regulator Bafin says that the alleged gold and FX manipulations are worse than the LIBOR scandal as they would include actual trades rather than reported rates. 
4) A new mechanism and administrator for the LIBOR fix (ICE) has been announced
5) New regulators, now the Federal Reserve and the Monetary Authority of Singapore, are joining the FX benchmark investigation.

The connection in all of these alleged scandals is that a limited number of large market participants are colluding to set benchmark prices that bring greater profits to themselves at the expense of their clients and other investors.  Large notional amounts of executed financial transactions are directly impacted by being priced at allegedly rigged rates.  All of the holdings of investors in funds whose assets are marked to market at manipulated rates are indirectly impacted when shares are purchased or sold. If true, the scope is such that large swaths of the investment landscape may have been affected by one or more of these collusions.

Banks have admitted wrongdoing in the LIBOR scandal and have paid $6 billion in fines to date.  Investigations continue in the ISDAfix, FX WM Reuters London Close, the London Gold fix, oil and other commodities as well.  It can be inferred from the banks’ personnel actions, that they too see improper activity by traders.  In fact, these reports have come up so quickly, in so many markets, that all benchmarks may very well now be suspect in the eyes of investors.  


What is most important is that regulators thoroughly review the actions of market players and then fully report to the investment world what has occurred.  Only by such investigations, proving to investors that the markets are not (or no longer) rigged against them, can new more reliable benchmarks be devised, and investor faith in the fairness and efficiency of markets be maintained (restored).

The “Great” Alleged FX Manipulation By Jon Wetreich and Jack Chen

When news broke of the alleged manipulation of the world’s largest market, the daily five trillion dollar foreign currency (“FX”) market, this appeared as another entry in the long list of scandals implicating some of the world’s largest financial institutions. The investigations are centered on the possibility, reported by Bloomberg News in June 2013, that dealers shared information and used client orders to influence widely-followed FX rates to boost trading profits. Specifically, the index is the WM/Reuters currency rates published by World Markets Co., a unit of State Street Corp., and Thomson Reuters Corp. at 4 PM London time, also known as the London close (“London Close”).
While we have seen reports of the FX market size in the press reports, what we have not come across are some estimates of possible dollars affected.
We have prepared the following table to provide a very high level assessment of the potential impact that such market manipulation could have on financial institutions. We obtained publicly available information about the portfolio holdings of a large public pension fund, two life insurers and industry information for life insurers and mutual funds. Our assumptions on portfolio turnover are based on our initial review of the public information. The assumption on percentage of trades manipulated is based upon our initial review of the currency mixes in the portfolios and on media reports of how the alleged manipulation occurred. For the table we provided a range of 10 to 30 bps of manipulation based upon a study reported by Bloomberg News.[1] A more accurate picture of damages requires a review of actual trades and portfolio information as well as a better understanding of whether the London Close was actually manipulated and, if so, how often and to what degree.
For our table:
§  We selected a pension fund and life insurers because they are more likely to have entered into trades referencing the London Close. 
§  We included four asset classes in our analysis: foreign equities, foreign bonds, forwards and swaps.
§  We considered American Depositary Receipts but based on preliminary information we do not see significant impact from any potential manipulation.
After the table we present a list of FAQ along with our answers.

Frequently Asked Questions
What are the allegations?
Although the WM/Reuters index provides exchange rates for 160 currencies hourly and half-hourly for the 21 most traded currencies, regulators are focused specifically on the rates that constitute the London Close.  Media reports say investigators suspect that FX dealers at banks may be sharing information and “banging the close,” which involves executing a large number of trades over the 1 or 2 minute period during which the rates are fixed for the London Close, to move the rates to their advantage.
Why is the London Close important?
The London Close rates have significant market importance as they are widely used by index and benchmark providers such as FTSE Group and MSCI World Index, which are in turn used by fund managers to determine their own performance and by banks to establish conversion rates for its customers. Many banks provide a service to their customers where they guarantee to trade for them at the London Close rates. Customers provide the trade amounts to their banks within the one hour prior to the London Close, also known as “the fix”.  Those banks that have agreed to make transactions for funds at the London Close need to push through the bulk of their trades during this window where possible to minimize losses from market movements.
Mutual funds, investment managers and others use the WM/Reuters rates to:
1.            Value, benchmark and mark to market their international portfolios because most main stock and bond index compilers, such as FTSE and MSCI, use these rates for the currency portion of their calculations.
2.            Execute spot trades with banks.
3.            Settle maturing futures contracts
How do banks make money trading typical FX and London Close FX?
Fix-related flows might be large but banks do not profit for executing the orders as they would in the course of other FX business. Banks generally make much of their profit in FX trading by capturing the difference or “spread” between bid and offer as they execute customer trades.  Although WM/Reuters rates provide a bid, mid-point and ask rate for each currency pair, most customer trades based upon these rates are converted at the mid-point.  Thus, there is no bank spread income for most of these trades.
A typical trade where the bank is earning a spread (and thus is not based off of the published fix) would work as follows.  If a bank sells a customer 1 million Euro at the ask rate of 1.3746 in return for a payment of $1,374,600 and then purchase the same 1 million Euro at the bid price for $1,374,500, the bank would have earned $100.  The wider the spread, the higher the bank’s profit.  A five point spread would yield the bank $500.  On a 5 or 10 million Euro transaction, which is a typical size in the interbank market, the 5-point spread would generate $2,500 or $5,000.
Two realities complicate this scenario for banks.  The first is that the interbank market rarely allows a bank to capture a spread much above 1 or 2 basis points on large trades.  The second is that the spread takes certain market costs into account, such as counterparty credit and market volatility and thus not all of the spread should be considered profit.
Nonetheless, the banks know the London Close orders before the fixing and may place trades to benefit from the fixing. As Michael Melvin and John Prins of BlackRock wrote in 2011 in “Equity Hedging and Exchange Rates at the London 4 P.M. Fix,” “The large market-makers are adept at trading in advance of the fix to push prices in their favor so that the fixing trades are profitable.”[2]
How could a bank profit by manipulating the WM/Reuters rates?
Example: a fund notifies the bank counterparty that a spot trade to sell €500 million / buy US dollars needs to be executed at the WM/Reuters fix that day.  If the fix rate was $1.4020, then the fund pays €500 million and receives $701 million.  If, however, the bank manipulated the fix so that the rate was 1.4000 (a manipulation of 20 pips or about 14 bps), then the fund would only receive $700 million US dollars, a manipulated loss of $1 million for the fund.  As many funds execute trades at the fix on a daily basis and in many different currencies, the number of potential manipulations can be substantial over a period of time.
Could activity perceived as potential manipulation be justifiable risk management?
Increased volatility can be a consequence of high volumes, similar to what can be observed at the opening and closing times in stock markets. Because the London Close is widely used by asset managers and other institutional clients, it is not unusual for a bank to receive a large order, sometimes extremely large, a few minutes before the fix.  The bank, having promised its customer the London Close rate, must reduce its position in a short amount of time or else the bank is stuck with a potentially large loss.  These flows are especially large at the end of each month and quarter as these managers put new money to work or reposition their index portfolios.
In a typical transaction, the bank’s spot traders would be able to fulfill the transaction by conducting a series of $5 or $10 million in the course of the trading day.  The result would be an average rate for the customer and a minimal impact on the marketplace.  This averaging is desirable because a market impact of a large transaction would move the market in the opposite direction desired by the client.  The client would effectively be trading against itself.  A one point in time fix, at 4pm London time, is not ideal for minimizing market impact, making price swings bigger and easier to achieve. 
Simple prudent risk management requires a bank to make sure that it is not harmed by the customer order.  For example, if the bank is running a $50 million short position in EURUSD, and the desk gets an order to buy $400 million, it is in the bank’s interest to close out its position before executing the client order.  Whether this constitutes front running (dealer profiting or avoiding losses for its own account by trading for its own account before executing a client order) or simple risk management explains some of the controversy surrounding the fix.
If the FX market is so large, how could it be manipulated?
In the 24 hours a day, 5 days a week world of currency trading, there is no closing price. For convenience, traders, funds and benchmark providers use the London Close as a reference point in a number of ways.  Thus, if banks really wanted to manipulate FX rates, by focusing on the London close, which is a sliver of time in the trading day, they can still affect a significant amount of FX activity.
Moreover, despite the overall size of the market, FX trading is actually concentrated in a handful of banks, where the top six banks reportedly receive collectively around 60% to 65% of FX customer flows. Because they receive client orders in advance of the London Close, and some traders allegedly discuss orders with counterparts at other firms, banks have an insight into the direction of rates before the London Close. That would allow them to maximize profits on the client orders and sometimes make their own additional bets.
Who are most likely to have been damaged by the alleged manipulation?
Because of the reference by large financial institutions to the WM/Reuters rates, we suspect that private individuals and smaller firms and entities that engage in FX transactions at all hours of the day are less likely to have been directly impacted by any potential manipulation. Smaller participants would experience indirect impact, for example, buying and selling fund shares that are based upon a share value including manipulated FX rates. The mutual funds, pension funds and other large institutions that trade at London Close rates will be the most directly impacted.
Why do fund managers track indices?
First and foremost, fund managers must do what the fund documents require, which often will reference published indices. Additionally, fund performance is often compared to an index, thereby further incentivizing managers to rely on published rates.
What do we not know?
Unfortunately there is in fact much that we do not know.  Unanswered questions that would provide critical information include:
Was there actual manipulation?[3]
Which banks were manipulating?
For how many years did the manipulation occur and did this occur on a daily basis or only sporadically?[4] 
Which currencies did they manipulate and by how much?
Is the London Close the only ongoing fix case?
In addition to its FX manipulation investigations, British, EU and US regulators have so far assessed a combined $6 billion in fines over manipulation of the London interbank offered rate, or Libor, used to price $300 trillion of securities from student loans to mortgages. Separately, more than a dozen banks have been subpoenaed by the U.S. Commodity Futures Trading Commission over allegations traders worked with brokers at ICAP Plc to manipulate ISDAfix, a benchmark used in interest-rate derivatives. Other benchmark price investigations currently under way include the London Gold Fix (set twice daily by five banks) and Brent Crude oil (involving three major oil companies and a pricing service).

About Financial PESTs (Promotion of Ethics, Simplicity and Transparency)
With deep experience and expertise in capital markets, banking, investment products, insurance, and legal disputes, Financial PESTs cover the gamut of Wall Street activities.  We promote eternal core values of ethical conduct, simplicity, and truth at the intersection of the legal, financial and regulatory worlds.
Economic development, wealth creation and social progress demand efficient global capital markets and financial infrastructure.  Guiding capital effectively to existing and new businesses, inventions, and industries is a noble endeavor when properly imbued with core values.  Unfortunately, the ideal of uncompromised promotion of ethics, simplicity, and truth often fails to win its battle against perceived self-interest within financial organizations.
Knowledge and information are powerful tools that best serve the common good in distributed, rather than concentrated, form.  Through writing, lecturing, and training, Financial PESTs bring our core values to center stage to advocate the sharing of knowledge and information so that today’s markets serve all people.  We analyze financial world issues to create clarity, context, and corrective proposals.  Financial PESTs push professionals to the highest standards of probity, candor, and conduct.  We distill complex topics to their simplest forms and campaign incessantly for the simplest implementations of financial transactions, fiduciary investment programs, government laws and regulatory rules.  We seek truth in the disclosure of risks, conflicts, agendas, and loyalties.
