The name Dick Usher is familiar to regular readers: he was the head of spot foreign exchange for JPMorgan, and the bank's alleged chief FX market manipulator, who was promptly fired after it was revealed that JPM was the bank coordinating the biggest FX rigging scheme in history, as initially revealed in "Another JPMorganite Busted For "Bandits' Club" Market Manipulation." Subsequent revelations - which would have been impossible without the tremendous reporting of Bloomberg's Liam Vaughan - showed that JPM was not alone: as recent legal actions confirmed, virtually every single bank was also a keen FX rigging participant. However, the undisputed ringleader was always America's largest bank, which would make sense: having a virtually unlimited balance sheet, JPM could outlast practically any margin call, and make money while its far smaller peers were closed out of trades... and existence.

But while the past year revealed that FX rigging was a just as pervasive, if not even more profitable industry for banks than the great Libor-fixing scandal (for details see "How To Rig FX Like A Pro "Bandit", And Make Millions In The Process"), the conventional wisdom was that it involved almost exclusively bankers at the largest global banks including JPM, Goldman, Deutsche, Barclays, RBS, HSBC, and UBS.

Now, courtesy of some more brilliant reporting by Vaughan, we can finally link banks with the other two facets of what has emerged to be an unprecedented FX-rigging "triangle" cartel: private sector companies that have no direct banking operations yet who have intimate prop trading exposure, as well as central banks themselves.

By "banks" we, of course, refer to the ringleader itself: JP Morgan, and its former head of spot forex trading in London, Dick Usher. As for the company that benefited from its heretofore secret participation in the biggest FX rigging scandal in history, it is none other than British Petroleum.

We learn about all this thanks to a story that begins with, of all thing, a story about freshwater fishing at a lake in Essex called "Wharf Pool."

As Bloomberg reports, "an hour away by train, in London’s financial district, the lake’s owners ply their trade. Wharf Pool was purchased for about 250,000 pounds ($388,000) in 2012 by Richard Usher, the former JPMorgan Chase & Co. trader at the center of a global investigation into corruption in the foreign-exchange market, and Andrew White, a currency trader at oil company BP Plc. "

The plot thickens: was there more than a passing connection between the head FX trader at JPM and White "who’s known in the market as Tubby, is one of half a dozen spot currency traders working for British Petroleum (BP) in London. He and his colleagues, most of them ex-bankers, decide which firms will carry out their foreign-exchange transactions. That makes them prized clients for banks seeking a slice of the business and a glimpse into potentially market-moving trades. Passing on information was a way to curry favor."

In short, a typical Over The Counter relationship between a banker and a buyside client, one which is largely unregulated and where the bank hopes to be able to frontrun the client's orders by providing the client with confidential market moving information, thus generating more business with the client in the future. In this case, however, the buyside client was not a typical hedge fund, but the FX trading group at one of the world's largest energy companies: a group which trades enormous amounts of FX every single day, both with intent to hedge, and to generate a profit.

The trading unit’s primary role is to manage the firm’s exposure to financial risks, including fluctuations in interest rates and foreign exchange, according to the company’s website. Unlike at most corporations, it also is run as a profit center, which means that in addition to hedging risks, traders can place their own bets on the direction of markets. The company doesn’t break out how much money the treasury unit makes

Basically, BP's energy operations were just a balance sheet funding cover: what its FX traders did in the front office was trade for a profit pure and simple, just like any prop trading desk or hedge fund anywhere else in the world. And it did so in collusion with a small group of market rigging individuals all located at the biggest, market-moving banks around the globe.

A quick reminder on the "Cartel":

The four banks in the Cartel controlled about 45 percent of the global spot-currency market, according to a survey by Euromoney Institutional Investor Plc, so information about their plans was valuable. Some days they worked together to push around the 4 p.m. fix, settlements with the banks show. The Cartel chat room was started by Usher as early as 2009, according to a person with knowledge of the matter. Usher had risen quickly to the top of his profession. After joining HBOS Plc in 2001, he was hired by Royal Bank of Scotland Group Plc in 2003 and a year later collected an industry award on his employer’s behalf.... The four members of the chat room ribbed each other like high school buddies. Usher was referred to as Feston because he resembled an overweight version of British chef Heston Blumenthal, according to people who have seen the chats. Matt Gardiner, a UBS trader based in Zurich, was called Fossil because he was a few years older than the others. Rohan Ramchandani, Citigroup’s cricket-loving head of spot trading, was called Ruggy, while Chris Ashton, the last one to join, was dubbed Robocop.

Now we can add BP too, a BP which doesn't even hide the prop-trading nature of its FX "hedging" group, which is located two blocks away from, wait for it, JPMorgan!

The two dozen traders in BP’s treasury trading unit are housed above a Porsche showroom on the second and third floors of the company’s office in Canary Wharf, an area of reclaimed docklands three miles east of the City of London, the historic financial district. The building, two blocks from JPMorgan’s, was completed in 2003 on the cusp of an oil boom. Lights in meeting rooms flick from green to white when someone enters, in keeping with the company’s corporate colors.

And while until today the last sentence would be pure conjecture, thanks to Bloomberg's release of exchanges between JPM and BP revealing the extent to which the "cartel" would stoop in order to make money for its members on a daily, risk-free basis, it is not a fact.

From Bloomberg:

Copies of messages sent to BP traders over the course of a year were provided to Bloomberg News by a person with access to the online conversations. The person, who redacted the names of banks sending the messages and dates of conversations, said they came from firms whose senior foreign-exchange traders belonged to a chat room called “The Cartel” that was set up by Usher and included dealers at JPMorgan, Citigroup Inc., Barclays Plc and UBS Group AG. The information offered an insight into currency moves minutes, sometimes hours before they happened. The messages could drag the U.K.’s biggest energy company into a scandal that has enveloped 11 banks and led to more than 30 traders from London to Singapore losing or being suspended from their jobs. Last month six banks were fined $4.3 billion for passing along information about their clients and working together to rig foreign-exchange markets.

Presenting BP: collusive, insider trading hedge fund extraordinaire. All comparisons and similarities to Enron are purely coincidental.

With revenue of almost $400 billion last year and operations in about 80 countries, BP trades large quantities of currency each day. Traders at the company regularly received valuable information from counterparts at some of the world’s biggest banks -- including tips about forthcoming trades, details of confidential client business and discussions of stop-losses, the trigger points for a flurry of buying or selling -- according to four traders with direct knowledge of the practice.

Of course, in any non-banana republic, whose regulatory and enforcement divisions were not captured by the same megacorp that is in question here, this would have been the basis for a massive lawsuit, one which would ultimately seek to break apart the company's "profitable" FX trading division from its core energy business. But not in this republic: after all, between one of the world's biggest banks and one of the world's biggest corporations, and a corrupt, crony government it should be clear to everyone by now just who calls the shots.

BP of course is quick to note that it did nothing illegal: after all the last thing the company needs is its own Enron-type scandal, where an ancillary business manages to drag down the entire company. Sure enough it has promptly denied everything:

BP said in a statement that it conducted an internal review after regulators began probing currency markets. “BP’s FX desk has relationships as a customer with 26 relationship banks, including JPMorgan, Citibank and Barclays,” the London-based company said. “BP has a robust framework of compliance requirements and internal controls which are constantly reviewed, and maintains an open dialogue with the appropriate regulators.” The firm, the third-largest publicly traded company in the U.K., hasn’t been investigated by regulators looking into currency manipulation, according to a person with knowledge of the matter. Chris Hamilton, a spokesman for the U.K. Financial Conduct Authority, declined to comment, as did representatives of JPMorgan, Barclays, Citigroup and UBS.

So how does one explain the joint equity interest in - for example - the little fishing lake ?

“BP’s Code of Conduct includes mandatory requirements for employees to disclose potential conflicts of interests internally,” the company said in response to a question about the commercial relationship between Usher and White through the fishing lake. “Following such disclosure, steps are taken to manage and monitor these appropriately. It is our policy not to comment on individuals.”

In other words, one can't. Which is how BP likes it. Which is also why Bloomberg was quite cautious with how it phrases BP's involvement into something that could promptly turn out to be Britain's own Enron:

While there’s no evidence that any BP traders were members of the Cartel, Usher participated in at least one chat room with White, according to a person who has examined conversations that included both men. It couldn’t be determined from the messages reviewed by Bloomberg News who sent the information to BP or whether BP employees acted on any of the tips.

They did, and this is how we know: "Traders at BP haven’t been accused of any wrongdoing. Last year, within hours of regulators announcing probes, the chats between BP and the banks were shut down, people with knowledge of the matter said. Soon after, a compliance officer was placed on the desk for the first time, one of them said."

Not exactly something one would do if one was, for lack of a better term, innocent.

And while we hold our breath until UK's justice (don't laugh please) system assigns blame - by which we mean a $19.95 one time settlement with a promise by BP it will never do it again - here is a glimpse at the full extent of just how this rigging took place:

In the clubby, lightly regulated world of foreign exchange, traders passed around tips to their circle of trusted contacts like candy. The victims: mutual-fund investors, pensioners and day traders who took the other side of a transaction at a lower price than they would have if they had the same information. ... In an undated message seen by Bloomberg News, a trader at a bank told BP he would be buying U.S. dollars against Australian dollars at the WM/Reuters fix at 4 p.m. in London, the one-minute window during which traders around the world exchange billions of dollars of currency on behalf of pension funds and asset managers. The message was received at BP about 30 minutes before the fix. By tipping his hand, the sender was telling BP about a potential fall in the Australian currency At about 3 p.m. in London on a different afternoon, BP traders were informed that banks were selling dollars against the yen at 4 p.m. In a third message, this one arriving as the oil company’s traders drank their first coffee of the morning, a trader at a bank said he had just sold a quantity of an emerging-market currency, to whom and the price he received. The settlements the banks reached with regulators reveal that in the minutes before 4 p.m. the traders would meet on chat rooms to discuss their positions and how they planned to execute them. Sometimes they also agreed to work together to push exchange rates around to boost their profits –- something they called “double-teaming.”

All of the above would be, if proven, criminal but in line with expectations: after all when given a carte blanche to do anything they want, humans will do just that, even if it means trample every regulation known to man. In fact, the bigger one's balance sheet, the greater one's percevied (and realized) leeway of sneaking between the legal cracks, facilitated by the number of politicians and regulators that have been coopted and outright purchased courtesy of said big balance sheet.

However, the true punchline is this: "[Usher] joined JPMorgan as head of spot foreign exchange in 2010, where he became a member of the now-defunct Bank of England’s Chief Dealers Sub Group, a collection of about a dozen currency traders and central bank officials who met at restaurants and bank offices to discuss industry developments."

In other words, all of this rigging, all of the FX manipulation, all of the criminal abuse of naive, innocent market participants took place with the Bank of England's own seal of approval. Which, of course, is why the BofE itself had to scapegoat its own sacrificial lamb to avoid any further connection to this criminal cartel - something it did in early November when it fired its Chief FX dealer, Martin Mallett, who on November 12 "was dismissed by the Bank of England yesterday for “serious misconduct relating to failure to adhere to the Bank’s internal policies,” according to a statement by the central bank today."

And just like that all loose ends have been cut off, although if we were Mr. Mallett, we would certainly keep away from loose nail guns, hot tubs or airplanes for the next several months.

In the meantime, after the mandatory pause of 3-6 months, all rigging, all manipulation, and all criminal abuse with blessing from the central bank itself will quietly return, because until the great (and as increasingly more predict, very violent) reset finally comes, nothing can possibly change in a system as corrupt as this one.
