Decision IntelMF Global
MF Global Bankruptcy
Estimated impact: $1.6B
Under CEO Jon Corzine's leadership, MF Global made a $6.3 billion bet on European sovereign debt using repo-to-maturity transactions. When European debt prices fell, margin calls drained the firm's liquidity, and $1.6 billion in customer funds were improperly used to meet obligations.
Decision context
Whether to approve CEO Corzine's strategy of leveraged bets on European sovereign bonds as a path to transforming MF Global from a brokerage into an investment bank.
What the record already said
The document below predates the decision. Everything after it is read from that document alone, so a reader can check each line against the words above it rather than take the reading on trust.
MF Global's Q3 FY2011 board materials documented a $6.3B gross exposure to European sovereign debt (Italy, Spain, Portugal, Ireland, Belgium) through repo-to-maturity transactions. The structure was disclosed as 'off-balance-sheet' despite carrying full market risk. CEO Jon Corzine personally directed the trades, overruling Chief Risk Officer Michael Roseman's objections — Roseman was replaced in January 2011 after refusing to approve increased sovereign exposure. CFO Henri Steenkamp's balance sheet reports understated the true liquidity risk of the RTM structure.

What a reader could have found without knowing the ending
- Chief Risk Officer (Roseman) removed in Jan 2011 after objecting to sovereign exposure — replaced by successor more receptive to CEO strategy
- Repo-to-maturity structure reported as off-balance-sheet while carrying full market risk
- CEO Corzine's personal direction of proprietary trades from executive office — blurring line between CEO and trader roles
- Initial board approvals set limit at $1B — breached multiple times before limit was raised retroactively to $4.75B, then $5B
- Financial Industry Regulatory Authority (FINRA) raised concerns about capital treatment of the RTM positions in summer 2011
DI would flag Corzine's removal of the CRO as the single most diagnostic event. A decision process where the CEO replaces the risk officer who challenges him — and the board allows it — is structurally incapable of circuit-breaking. The retroactive limit raises (rather than forced unwinds) is the signature of gambler's fallacy: each loss cycle produces a 'we're closer to the reversal' rationalization rather than a mandatory trim. The $1.6B customer-fund shortfall that ended the firm was the final-stage expression of a decision process that had already ceased functioning.
Written after the outcome was known. Nothing here can be falsified, which is why it sits below the document rather than above it.
What the company’s own filing already carried
Not our reading of a memo. MF Global's own 10-K, filed 2010-05-28 (8 months before the 2011 decision), was read by the audit engine's deterministic structural layer: the same detectors that run on every audit, with no language model involved. Everything below is drawn from the company's own disclosure, before any knowledge of what followed, and never from the decision itself.
Would not absorb the hit: if the flagged risk fires, nothing disclosed in the structure would materially absorb that loss.
- Single-counterparty concentrationunprotected
- Commodity-price-linked cash flowsunprotected
- Hostile / competitive auctionunprotected
- This reads the company's own 10-K (filed 8 months before the decision), not the decision memo itself, so it can only understate what a full audit of the memo would surface.
- It reads the structure of the situation, not the trigger: whether a shock to the flagged conditions would be absorbed, never that a shock arrives.
- A reading of a dated filing, not a prediction: every condition can be checked against the company's own 10-K.

Lessons learned
- A CEO's prior political stature and reputation can create authority bias that suppresses board-level risk oversight.
- Concentrated directional bets funded by customer money violate the fundamental trust of brokerage operations.
- Anchoring to past success in government bond markets ignores the different risk profile of sovereign credit exposure.
