Rogue trader

Société Générale, leader mondiale nei derivati azionari, ha perso 5 miliardi di euro, per colpa di un suo trader. Jérome Kerviel, un francese 31enne, che è riuscito a nascondere, per mesi, le proprie posizioni speculative sugli indici azionari europei, grazie alla conoscenza approfondita dei sistemi informatici acquisita nella sua precedente esperienza nel back office della banca. Questo “genio”, invece di fare arbitraggi sui future azionari, aveva accumulato un posizione rialzista con equity derivatives plain vanilla pari a circa 50 miliardi di euro, riuscendo ad eludere i sofisticati sistemi di controllo e di risk management della SocGén. Ricordate Nick Leeson, il trader-canaglia che fece fallire la Barings nel 1995 con le sue speculazioni alla borsa di Singapore? La versione ufficiale è sempre la stessa: è tutta colpa di un solo truffatore ...povera banca! Nessuno si era accorto di nulla fino al weekend scorso e lunedì si sono affrettati a chiudere l'enorme posizione lunga sugli index futures europei, mentre il mercato si stava schiantando! Ovviamente devono aver venduto sui minimi... anzi il mercato l'hanno affossato loro per chiudere mezzo milione di contratti futures!

p.s
“There is certainly an irony in the fact that the entities that were being demonised at that time by many – soverein wealth funds and hedge funds – have in recent months been the saviours rather than the demons, with hedge funds providing much-needed liquidity to the markets, and sovereign wealth funds providing much-needed capital to systemically important banks” (Charlie McCreevy)

SocGen: la versione del trader che ha messo in crisi la banca
di Andrea Malan


Parigi non è l'Italia, ma il contenuto della deposizione resa nel fine settimana da Jerome Kerviel, il trader che ha messo in crisi la Société Générale, è filtrato abbondantemente sulla stampa francese. La linea difensiva del 31enne operatore di Borsa era già nota nelle linee generali, ma si arricchisce di nuovi dettagli che contraddicono la versione delineata dalla banca stessa nel comunicato del 27 gennaio.
Kerviel riconosce di «aver preso grosse posizioni, che potrebbero essere qualificate come al di sopra del mio mandato », e di averle «mascherate con operazioni fittizie». Ma il trader sostiene che «la gerarchia della banca avrebbe chiuso gli occhi sulle sue operazioni »; secondo lui, «le tecniche che ho utilizzato per mascherarle sono tutt'altro che sofisticate, e qualsiasi controllo effettuato correttamente era in grado di scoprirle». Kerviel ha aggiunto che le operazioni di dissimulazione da lui compiute sarebbero normali all'interno della banca; per esempio, per «nascondere » guadagni e non solo perdite. Come la tecnica del "materasso": «Quando un manager a un certo punto dell'anno ritiene che il suo gruppo abbia raggiunto gli obiettivi, può decidere di trasferire una parte di essi sull'anno seguente,dissimulandoli in vari modi». Per quanto riguarda l'attività di trading, è d'uso una certa flessibilità accordata di volta in volta ai trader. «Fin che guadagnamo dice in sostanza Kerviel - e che la cosa non è troppo appariscente, si dice nulla». Non va dimenticato, a questo proposito, che le sue posizioni erano in attivo almeno fino a fine 2007. Nel corso di quell'anno il trader avrebbe messo a segno guadagni per 1,4 miliardi. «Nessuno ha mai realizzato un risultato simile, che è pari a metà del totale degli utili della sezione indici azionari», dice quasi orgoglioso Kerviel. Il problema, per lui, diventa però di giustificarlo ai superiori. Riduce allora i guadagni a 55 milioni con le citate operazioni fittizie. Poiché si tratta comunque di un buon profitto, chiede un bonus di 600mila euro; ne avrebbe ottenuti 300mila, che avrebbero dovuto essere pagati il prossimo mese di marzo. In ogni caso, l'obiettivo di Kerviel non sarebbe stato l'arricchimento personale diretto, ma solo per via indiretta ( con l'aumento degli utili della banca) dei propri compensi. Una tesi che la procura sembra aver accolto, in quanto ha lasciato cadere l'accusa di frode. Ma perché Kerviel si sarebbe lanciato in una simile avventura? Forse per spirito di rivincita, visto che dichiara di «aver capito già nella prima intervista del 2005 che ero molto meno considerato degli altri trader».
Per alcuni aspetti, la ricostruzione dell'imputato non è dissimile da quella della banca. Secondo SocGen, i meccanismi di copertura adottati sarebbero stati complessi e legati alla sua attività precedente al middle office, cioè il reparto che controlla il trading: Kerviel avrebbe utilizzato codici di altri operatori per alterare operazioni,falsificato documenti, cambiato continuamente tipo di strumenti per ridurre la possibilità di essere scoperto. La sua deposizione lascia però intendere che la banca ha avuto più di un'occasione per scoprirlo. Kerviel dice per esempio che «il solo fatto che non ho preso di vacanze nel 2007 avrebbe dovuto metterli sull'avviso». Alcune banche d'investimento, in effetti, obbligano di fatto i trader a prendere un certo numero di ferie: così, "trasmettono" i portafogli ai colleghi. Secondo SocGen, invece, gli artifici utilizzati da Kerviel gli avrebbero permesso di sfuggire ai controlli fino a «qualche giorno prima» di venerdì 18 gennaio, quando «è stato individuato su una controparte un rischio anomalo che è stato segnalato alla SocGen ». Poiché le spiegazioni da lui fornite non erano convincenti, viene fatta una verifica con la controparte (Deutsche Bank, ndr),ma l'e-mail di risposta sembra sospetta. Nella giornata del 18 il problema risale tutta la catena gerarchica, fino al numero uno della banca d'investimento di SocGen,JeanPierre Mustier. Nel pomeriggio della domenica 20 gennaio viene quantificato il rischio complessivo di circa 50 miliardi. Bouton avverte la Banca di Francia e convoca il cda, che si riunisce in serata e respinge le sue dimissioni. Segue poi, da lunedì a mercoledì scorsi, la liquidazione precipitosa che ha portato alle perdite di 4,9 miliardi.
La gerarchia della banca, sapeva o non sapeva delle operazioni a rischio? Solo l'inchiesta potrà accertarlo. Kerviel ha detto ai magistrati che «Nel corso del 2007 i miei collaboratori hanno ricevuto parecchie e-mail dal back office (gli uffici amministrativi) che chiedevano spiegazioni sulle mie operazioni ». Se esistono davvero, tali messaggi non dovrebbero essere difficili da ritrovare negli archivi informatici. Senza contare l'allarme sulle posizioni di Kerviel trasmesso nel novembre 2007 alla SocGen dal mercato future tedesco Eurex.

A Trader’s Secrets, a Bank’s Missteps
By NELSON D. SCHWARTZ and KATRIN BENNHOLD
PARIS — The first e-mail message arrived in Société Générale’s offices on Nov. 7. The surveillance office at Eurex, one of Europe’s biggest exchanges, alerted a compliance officer at the bank that for seven months a trader named Jérôme Kerviel had engaged in not just one but “several transactions” that had raised red flags.

Société Générale, taking its time, responded on Nov. 20, when another risk-control expert at the bank replied that there was nothing irregular. “The recent volatility increase on the U.S. and European stock markets explains our new need for after-hours trading,” the bank official wrote about Mr. Kerviel’s trades, according to e-mail messages reviewed by The New York Times.

A second e-mail message from Eurex came on Nov. 26. Not satisfied by the bank’s explanation, the bourse demanded more details. Société Générale provided them on Dec. 10 — and both Eurex and the bank’s own risk managers let the matter of Mr. Kerviel’s trades drop.

By the time Mr. Kerviel set off another alarm, on Jan 18, five weeks later, it was too late. Though he had a profit on his surreptitious trading of roughly $2 billion by late December, his gain quickly went south. It would balloon into a loss of more than $7 billion as the bank frantically unwound Mr. Kerviel’s financial positions on Jan. 21-22.

A spokeswoman for Société Générale declined to comment on the contents of the warning from Eurex or the bank’s response, citing an internal inquiry by a special committee of independent directors now under way.

Overlooking the warnings by Eurex about Mr. Kerviel was only one of a series of missteps by Société Générale that led to his staggering loss.

The 144-year-old bank allowed a culture of risk to flourish, creating major flaws in its operations that enabled the rogue trader’s activities to go undetected, according to bank officials, investigators and traders who worked with Mr. Kerviel.

Far from being discouraged from placing big bets, Société Générale traders were rewarded for making risky investments with the bank’s money. It was not uncommon for traders to briefly exceed limits imposed on their trading before pulling back, despite controls meant to prohibit this.

“I have a suspicion that this was inevitable, given the way things were engineered,” said Yves-Marie Laulan, a former chief economist at Société Générale and a longtime Paris banker. “It’s a necessary warning that these things are so complicated that they are hard to control.”

While management depicts the 31-year-old Mr. Kerviel as a lone operator who spiraled out of control, interviews with current and former Société Générale employees suggest that he was also the product of an environment where risk taking was embraced, as long as it made money for the bank.

“If this scam had been uncovered in November, when he was still up, he would have been fired but I suspect we would have heard very little about it,” said a French financial official who insisted on anonymity because of his role in the investigation.

The Soldier-Monks

The damage wrought by Mr. Kerviel comes in the wake of two trends that reshaped Société Générale: the explosive growth of its derivatives business and its use of its own money to make bets on the market, known as proprietary trading.

Throughout Société Générale’s sprawling derivatives business, said one current employee who used to work with Mr. Kerviel, traders were encouraged to make proprietary bets, even on desks that specialized in what top executives called “plain vanilla products,” like the team where Mr. Kerviel worked, Delta One.

“You must take positions, even if you are not a proprietary trader,” said this employee, who insisted on anonymity because he was not authorized to talk to the press. “During appraisals by bosses, they made it clear you were judged by how well you did your basic job, as well as how much money you made on prop trades.”

Mr. Kerviel told French prosecutors as much. Asked if his superiors knew of his activities, he said, “at the beginning, just as at the end of my maneuvers, they didn’t want to intervene,” adding, “They know the machinery.”

Kinner Lakhani, an analyst with ABN Amro in London: said, “Unlike some of their peers, Soc Gen was not shy about taking proprietary trading risks. Perhaps such businesses grew faster than risk management could cope.”

Within Société Générale’s corporate and investment bank, according to Mr. Lakhani, the percentage of revenue from market-making and proprietary trading rose to about 35 percent by mid-2007 from 29 percent in 2004.

The derivatives group started in the 1980s as a small team of highly trained and highly regarded engineers and mathematicians from the best schools. They quickly became known as “les moines-soldats,” the soldier-monks. And as their importance inside the bank grew, their confidence, even arrogance, grew with it.

Like the devout and disciplined fighters they were named for — the monks who fought in the Crusades — the soldier-monks of Société Générale prided themselves on rising above the passions that moved the masses.

Similarly, Société Générale’s soldier-monks believed that they could manage both the risk inherent in betting on the markets — through complex computer models — and the ardor of their regular traders, through controls.

Their hubris was having too much faith in their power to do either.

But they were dedicated to making Société Générale a world-class power in derivatives and, like the knights of old, they were fiercely competitive, both on and off the trading floor.

“We considered it a mission,” recalled Antoine Paille, who recruited Jean-Pierre Mustier, now the head of Société Générale’s corporate and investment bank. It was Mr. Mustier who ultimately confronted Mr. Kerviel after his fraud was discovered on Jan. 18.

While based in the United States in the 1990s, Mr. Mustier and another derivatives executive, Luc François, organized a sailing competition with other banks and steered the Société Générale boat to victory. Mr. François eventually rose to head the derivatives business but reportedly left last month after the revelation of Mr. Kerviel’s trades.

A Red Flag Cited

Mr. Kerviel was never viewed as soldier-monk material. He was a provincial from decidedly middle-class stock — the son of a hairdresser and a metal- shop teacher — but he possessed an advantage that his better-bred superiors did not.

In his five years toiling in the back office before being promoted to Delta One in 2005, he had become expertly familiar with the proprietary system Société Générale used to book trades, known as Eliot inside the bank. While the risk-control department did monitor the bank’s overall positions very closely, it did not verify the data Mr. Kerviel entered into Eliot. And Mr. Kerviel knew the timing of the nightly reconciliation of the day’s trades by Eliot, so he was able to expertly delete and then re-enter his unauthorized transactions without being caught.

Mr. Kerviel’s method of entering trades was one red flag cited by Eurex in its initial warning, along with questions about two “large” positions — one net short position in DAX futures and one net long position in Euro Stoxx 50 futures. In the same letter, they asked what his investment strategy was and why these transactions were often entered through a London-based Société Générale subsidiary called FIMAT Futures Limited. Eurex even inquired whether Mr. Kerviel had entered the transaction automatically or manually.

“Please explain the background for this procedure,” two Eurex officials wrote to Xavier de la Maisonneuve, a compliance officer at Société Générale who has been questioned by investigators.

Vincent Duclos, another compliance officer in the equity derivatives division, not yet questioned by the police, provided the Nov. 20 and Dec. 10 responses to Eurex. His replies in part were based on accounts provided by Mr. Kerviel and his supervisor, as well as a compliance officer at FIMAT, said Jean Veil, a lawyer for Société Générale. Mr. Kerviel’s “supervisor had signaled that there was no anomaly whatsoever,” Mr. Veil said.

Mr. De la Maisonneuve, who received the initial query on Nov. 7, said the bank gets 15 to 20 queries from different exchanges each year, many of them from Eurex.

In a telephone interview Monday night, he insisted his team had been in telephone contact with Eurex after their two letters in November to ensure it would fully answer their queries.

“Their questions were based purely on strategy and procedure,” he said. “At no moment of these conversations was there any mention of abnormal volumes. They considered our second written response adequate and satisfying.”

He added that Eurex did not take up Société Générale’s offer of a conference call to further discuss the matter after the Dec. 10 letter.

A top official at Société Générale, who insisted on anonymity because of the sensitivity of the matter, said that in the weeks after the Eurex warning, Mr. Kerviel was shaken, and took additional steps to cover his tracks. He tried to manipulate areas of the internal risk-control system he was unfamiliar with, which ultimately led to the discovery of his suspected fraud in mid-January.

In his testimony to the police, however, Mr. Kerviel identified two members of the Delta One team he said were familiar with his activities going back to last April. These colleagues, according to lawyers familiar with the case, were Martial Rouyère, head of the Delta One trading desk, and his deputy, Eric Cordelle. Mr. Rouyère has since been questioned by the French authorities. Mr. Veil said he expected Mr. Kerviel’s “entire hierarchy,” including Mr. Mustier, to eventually be questioned by the police.

Given that Mr. Kerviel was able to exceed trading limits and evade detection for so long, as well as Société Générale’s handling of Eurex’s November warnings, “we can easily infer that the internal controls were either inadequately designed or have not been operating effectively and efficiently,” said Francis Hounnongandji, a corporate governance expert who is also president of the French chapter of the Association of Certified Fraud Examiners.

That conclusion is being echoed at the highest levels of the French government. On Monday, Finance Minister Christine Lagarde said, “Very clearly, certain mechanisms of internal controls of Société Générale did not function, and those that functioned were not always followed by appropriate modifications.”

In meetings with investors in recent days, Société Générale’s chief executive, Daniel Bouton, has admitted his bank’s internal systems did not keep up with the pace of growth in the derivatives business. “He told them while our derivatives business was going 130 miles an hour, risk control was only going 80,” according to one analyst who covers Société Générale but insisted on anonymity.

He added that with traders making so much money, the analyst added, ”they were untouchable; they had the power.”

Pascal Decque, an analyst who covers Société Générale in Paris for Natxis, agreed that the bank was more willing to take risks than any of its French rivals, including BNP Paribas, which is rumored to be considering a bid for Société Générale.

As an example, he cited Société Générale’s loss of 2 billion euros stemming from subprime-related investments — twice the size of the hit BNP Paribas took, even though BNP is larger.

Suspiciously Good Timing

The Securities and Exchange Commission is investigating whether Robert Day, an American Société Générale board member, violated insider trading rules by selling shares worth 45 million euros before the bank’s audit committee was informed of the subprime loss.

Société Générale and a spokesman for Mr. Day said last week that the share sales by Mr. Day and his family’s trusts occurred in several transactions from December 2007 to Jan. 18, during a predetermined window when directors were allowed to exercise options. Both statements said all required disclosures were made, and “no inside information was used in any way” with respect to these sales.

As for Société Générale, the price of its hubris is still to be tallied. Like many observers, Mr. Decque believes it likely that the bank will eventually lose its independence as a result of Mr. Kerviel’s losses, most likely via an acquisition by another French bank.

“Soc Gen was brilliant in their achievement, they were the world leader in derivatives,” Mr. Decque said. “Maybe when you are that good, you think you will never fail.”
