Societe Generale (A): The Jerome Kerviel Affair Custom Case Solution & Analysis

Evidence Brief: Societe Generale (A)

Financial Metrics

• Total unauthorized exposure: 50 billion Euros (Exhibit 1)
• Final net loss after liquidation: 4.9 billion Euros (Section: The Unwinding)
• Market capitalization loss: Approximately 15 billion Euros within 48 hours of announcement (Section: Market Reaction)
• Planned capital increase: 5.5 billion Euros to restore Tier 1 capital ratios (Section: The Aftermath)
• 2007 Net Income: Originally reported at 5.5 billion Euros, restated to 947 million Euros (Financial Summary)

Operational Facts

• Desk: Delta One desk within the Corporate and Investment Banking (CIB) division.
• Strategy: Arbitrage between equity index futures and exchange-traded funds.
• Control Failures: 75 internal alerts triggered between June 2006 and January 2008.
• Employee History: Jerome Kerviel spent five years in the middle office (back office) before moving to the trading desk in 2005. This provided intimate knowledge of booking systems and control protocols.
• Methods: Use of fictitious trades, stolen passwords, and cancelled trades before the five-day settlement window to hide directional bets.

Stakeholder Positions

• Daniel Bouton (CEO): Maintained that the bank was a victim of a criminal genius. Offered resignation twice; both times rejected by the board.
• Jean-Pierre Mustier (Head of CIB): Responsible for the division where the fraud occurred. Focused on the technical nature of the deception.
• Jerome Kerviel (Trader): Claimed superiors were aware of his positions as long as they were profitable. Stated his goal was to earn money for the bank, not personal theft.
• French Central Bank (Banque de France): Investigated the systemic risk posed by the massive liquidation of positions in a volatile market.

Information Gaps

• Direct evidence of supervisor emails or verbal approvals regarding the 75 alerts.
• Detailed breakdown of the 2.8 billion Euro profit Kerviel supposedly held before the positions turned into a loss.
• Specific audit logs showing why the IT department did not flag the frequent password changes and access overrides.

Strategic Analysis

Core Strategic Question

• How can Societe Generale restore institutional credibility when its internal controls were systematically bypassed by a junior employee?
• Is the current high-frequency, high-volume trading model compatible with the risk appetite of a traditional retail and investment bank?

Structural Analysis

The failure at Societe Generale was not a failure of technology, but a failure of the internal value chain. The middle office, designed to be a check on the front office, was compromised by a trader who understood the plumbing of the bank better than his supervisors. This created an information asymmetry where the controller was less informed than the controlled.

Strategic Options

Option 1: Complete Operational Segregation and Cultural Reset

• Rationale: Restore trust by making risk management the dominant power center in the bank.
• Trade-offs: Slower execution in trading and potential talent flight to less restrictive competitors.
• Requirements: New leadership in the risk division with veto power over any desk.

Option 2: Exit Proprietary Directional Trading

• Rationale: Align the bank with a lower risk profile to protect the retail brand and capital base.
Trade-offs: Significant reduction in CIB revenue and market share in European equities. Requirements: Divestiture of the Delta One desk and restructuring of the investment arm.

Preliminary Recommendation

Societe Generale must pursue Option 1. The bank cannot afford to exit investment banking entirely without ceding its position in the European market. However, it must implement a hard separation between the front and back offices. This includes a mandatory policy where no trader can ever have worked in the middle office of the same firm. The bank must also move from a system of alerts to a system of automated blockages.

Implementation Roadmap

Critical Path

• Month 1: Execute the 5.5 billion Euro rights issue to stabilize the balance sheet and prevent a credit rating downgrade.
• Month 2: Appoint an independent special committee to audit all trading desks, starting with Delta One and Arbitrage.
• Month 3: Implement biometric or multi-factor authentication for all trade booking systems to prevent password sharing.
• Month 4: Establish a mandatory two-week consecutive vacation policy for all traders, during which their accounts are frozen and audited.

Key Constraints

• Talent Retention: Top traders may leave if the new controls are perceived as too restrictive or if bonuses are clawed back to cover the loss.
• Regulatory Pressure: The French government and European regulators may impose even stricter capital requirements that limit growth.

Risk-Adjusted Implementation Strategy

The implementation will focus on a hard-lock IT architecture. Instead of alerts that require human intervention, the system will automatically suspend trading privileges if a position exceeds a pre-set limit or if a trade is not matched with a counterparty within 24 hours. This removes the human element of ignoring warnings because of high profits.

Executive Review and BLUF

BLUF

Societe Generale suffered a 4.9 billion Euro loss because management prioritized profit over process integrity. Jerome Kerviel did not break the bank; he exploited a culture that chose to ignore 75 red flags. The bank must immediately raise 5.5 billion Euros in capital and replace the current alert-based risk system with an automated, zero-tolerance blocking system. Success depends on ending the era where the front office can override back-office warnings. The bank stays in the investment business but only under a new, restrictive operational mandate.

Dangerous Assumption

The most dangerous assumption is that Kerviel was a lone actor. While he may have executed the trades alone, the systemic silence of his supervisors suggests a broader cultural acceptance of hidden risk as long as it generated revenue. Fixing the software without firing the management that ignored the alerts will lead to a repeat of this crisis.

Unaddressed Risks

• Liquidity Risk: The plan assumes the market can absorb a 5.5 billion Euro rights issue during a period of extreme volatility without a massive share price collapse.
• Contagion Risk: Counterparties may reduce credit lines to Societe Generale if they perceive the internal audit as insufficient, leading to a liquidity squeeze.

Unconsidered Alternative

The analysis focused on fixing the bank. A viable alternative is a merger with a larger, more stable institution like BNP Paribas or a global player. This would provide the capital and the risk management culture required to stabilize the operations, though it would cost the bank its independence and likely face political opposition in France.
