Archegos Capital Management
$20 Billion Vanished in 48 Hours: The Secret Leverage Bomb
Filed: March 26, 2021
Bill Hwang turned $200 million into $36 billion using total return swaps — derivatives that let him build massive positions without disclosing them. When ViacomCBS stock dropped, Archegos's hidden leverage imploded. The banks that had lent him money (Credit Suisse lost $5.5B, Nomura $2.9B) were forced to liquidate positions in a fire sale. Total losses: $20+ billion in two days.
The Numbers
Timeline of Collapse
-
Bill Hwang founds Archegos as a family office after his previous hedge fund, Tiger Asia, pleaded guilty to insider trading.
-
Hwang turns $200M into $36B using total return swaps with 6+ prime brokers — none of whom knew his total exposure.
-
ViacomCBS announces $3B secondary offering. Stock drops 9%. Archegos is massively long ViacomCBS via swaps.
-
Banks call Hwang to emergency meeting. Discover his total exposure is $100B+ gross — across all of them combined. None knew about the others.
-
Banks liquidate Archegos positions in coordinated fire sale. $20B+ in market value destroyed. Credit Suisse loses $5.5B.
-
Archegos defaults. Credit Suisse fires risk management head. Nomura takes $2.9B loss. SEC opens investigation.
Root Cause Analysis
What actually killed Archegos Capital Management.
- ▸ Total return swaps let Archegos build $100B+ positions without disclosing them on any 13F filing
- ▸ Each prime broker saw only their piece of the leverage — nobody knew Hwang was levered 5:1 across six banks simultaneously
- ▸ Banks competed to lend Hwang more money because his trading generated massive fees — risk management was overruled by the revenue desk
- ▸ Concentrated bets: Archegos was the largest holder of ViacomCBS, GSX Techedu, and several other stocks — any selloff would crash them all
Lessons Learned
What investors, executives, and regulators should take away.
- ! Total return swaps are disclosure loopholes — they let investors build positions 5x larger than what the public can see
- ! When every prime broker thinks they're the only one lending, the leverage is systemic — and invisible
- ! Credit Suisse lost $5.5B on ONE client. One client that had already been convicted of insider trading.
- ! Family offices are supposed to manage family wealth — not run $36B levered hedge funds outside regulatory oversight
