Archegos Capital Collapse: A Deep Dive into the 2021 Market Shock

What Happened The Archegos Capital Management collapse unfolded dramatically in late March 2021, sending shockwaves through the global financial markets. On Friday, March 26, 2021, several major investment banks, including Credit Suisse and Nomura, announced significant losses tied to a U.S. client. While they didn't initially name the client, it quickly became evident that the culprit was Archegos Capital Management, a family office run by Bill Hwang. The immediate trigger was Archegos's inability to meet margin calls on highly leveraged positions, primarily in a concentrated portfolio of media and tech stocks, including ViacomCBS VIAC and Discovery DISCA.
