Summary
Archegos Capital Management experienced a catastrophic collapse in March 2021 that sent shockwaves through Wall Street's largest investment banks. The $10 billion family office, founded by New York investor Bill Hwang, defaulted on margin calls on March 26, 2021, after a sharp decline in Viacom CBS share price following the media company's stock sale exposed the fund's concentrated leverage in technology and media equities. The crisis triggered a $20 billion fire sale of positions as prime brokers—including Credit Suisse, Nomura, Goldman Sachs, Morgan Stanley, Deutsche Bank, UBS, Wells Fargo, and MUFG—rushed simultaneously to liquidate Archegos' holdings to recover collateral owed.
The financial damage was severe and unevenly distributed. Credit Suisse, which acted as one of Archegos' primary brokers, suffered the heaviest loss at $5.5 billion, the largest hit among all prime brokers. Nomura Holdings reported a loss of 307 billion yen ($2.87 billion), which the bank's Chief Financial Officer Takumi Kitamura attributed to "winding down of positions and changes in market prices," while stressing that Nomura had adopted a "disciplined approach to exit" in order to minimize broader market impact. Morgan Stanley disclosed losses of nearly $911 million, comprising $644 million from selling stocks tied to Archegos' positions and an additional $267 million in derisk activities.
The public alarm bells rang on Monday, March 29, when Credit Suisse and Nomura both announced that the event had materially impacted their prime brokerage businesses. However, the underlying collapse had occurred faster: within one week of the ViacomCBS decline, Archegos' capital was effectively wiped out. The crisis exposed fundamental weaknesses in Archegos' own risk management—specifically over-concentration of investments in a limited portfolio of technology stocks leveraged through derivative instruments—and revealed gaps in prime brokers' monitoring of correlated exposures across multiple counterparties. The spectacle underscored systemic risks inherent in the prime brokerage model when a single client maintains substantial leveraged positions across multiple banks without sufficient transparency or coordination mechanisms.
