Archegos collapse
2021.03
Margin calls and forced sales of concentrated leveraged positions led to losses at counterpart banks.
The collapse phase in late month 3. Recorded at monthly precision rather than presented as a falsely exact single date.
Conditions at the time
The Archegos family office invested in selected equities with high leverage through total return swaps and other instruments.
How events unfolded
Price declines in late month 3 triggered margin calls, and position sales caused further declines.
Stakeholders and impacts
Archegos, prime-broker banks and investors in the affected equities were exposed to the liquidation shock.
Information available at the time
The difficulty of seeing counterparty exposures across banks at a glance posed a risk-management challenge.
Findings confirmed later
After the event, the Federal Reserve reaffirmed supervisory expectations for banks’ due diligence and margin management.
Alternative interpretations and limitations
This does not mean that all family offices carry the same risks; concentration, collateral and counterparty management are central.
Source-based context and interpretation
The Fed described concentrated equity losses triggering margin calls, forced sales and further declines that imposed bank losses. Subsequent guidance reaffirmed expectations for due diligence, counterparty risk and margin management. A non-bank investor transmitted losses to financing banks. ASSETCASTING interpretation: Multiple intermediaries do not diversify identical underlying positions. Examine simultaneous collateral declines and margin demands. Family offices differ; assess concentration, leverage and the information available to each counterparty.
