Credit Suisse Archegos Capital Losses
Estimated impact: $5.5B
Credit Suisse lost $5.5 billion when family office Archegos Capital defaulted on margin calls from highly leveraged total return swap positions. Despite receiving multiple internal warnings about Archegos's concentrated exposure, the prime brokerage division chose to maintain the profitable relationship rather than reduce limits.
Decision context
Whether to enforce margin requirements and reduce exposure to Archegos Capital as the family office's concentrated leveraged positions grew beyond normal risk thresholds.
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.
Credit Suisse prime services risk committee reviewed Archegos Capital exposure in late 2020 and early 2021. The committee documented that Archegos's aggregate gross exposure across prime brokers exceeded $50B against reported family-office equity of ~$10B, implying effective leverage of 5-8x on concentrated single-stock positions. Credit Suisse's initial margin requirements on Archegos total return swaps were set materially below Goldman Sachs and Morgan Stanley — a competitive-intensity decision rather than a risk-based one. Earlier internal recommendations to raise margin were deferred pending relationship-revenue discussions.

What a reader could have found without knowing the ending
- Initial margin below peer banks on identical counterparty — competitive-pricing decision overriding risk
- Knowledge that Bill Hwang's prior Tiger Asia vehicle settled SEC insider-trading charges in 2012
- Archegos aggregate gross exposure across prime brokers estimated at 5x+ reported family-office capital
- Prime services risk function did not have authority to force margin increases over relationship-banker objection
- CRO pushback on Archegos limits deferred to relationship-revenue discussions
DI would flag Credit Suisse's Archegos risk decisions as the canonical revenue-anchor override of risk function. The bank's below-peer margin was a commercially-motivated choice that a bias-adjusted process would have required competitive/risk trade-off documentation for — 'we accept $X of additional tail risk to compete with GS on this specific counterparty' should have been an explicit ratified decision, not an emergent drift. Hwang's 2012 SEC settlement made the halo-effect operative: 'we know this counterparty' overrode base-rate concern about concentrated leverage.
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. Credit Suisse's own 20-F, filed 2020-03-30 (10 months before the 2021 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.
Survivable as structured: if the flagged risk fires, the deal has the exits, cushions, or staging to absorb the hit and continue.
The structural layer flagged no unabsorbed condition in this filing.
- This reads the company's own 20-F (filed 10 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 20-F.

Lessons learned
- Revenue anchoring causes relationship managers to underweight risk signals when a client is highly profitable.
- Status quo bias in risk management means limits that should be tightened remain unchanged until it is too late.
- When multiple banks have the same exposure, the first to act minimizes losses while the last absorbs the worst.
