The Man Who Lost $20 Billion in 2 Days

The True Story of Bill Hwang, Wall Street's Most Dangerous Ghost
Before he lost it all, all $20 billion, Bill Hwang was the greatest trader you had never heard of. That anonymity was intentional, and it became his most powerful weapon.
The Prodigy
Born in South Korea, Hwang moved to the United States as a child and eventually joined Julian Robertson's legendary Tiger Management, one of the most successful hedge funds of the 1990s. There he sharpened his instincts into something close to a superpower.
He was obsessive, brilliant, and deeply religious. He named his firm Archegos, a Greek term meaning “leader,” used in the Bible to reference Christ. He commissioned artwork depicting the blood of Christ washing over the New York City skyline. He drove a Hyundai. He hosted Scripture readings in his Manhattan office.
He did not look like a man constructing one of the most dangerous financial weapons ever assembled. But he was.
The Scheme
When COVID locked down the world in March 2020, Hwang began quietly building enormous positions in a handful of stocks from his Manhattan apartment, using a financial instrument called total return swaps.
Swaps were the perfect cloak.
By using them, Archegos never had to disclose its massive holdings. The shares were held by the banks. Hwang remained invisible, a ghost controlling $35 billion worth of exposure from the shadows.
His genius was simple: he went not to one bank, but to many. Goldman Sachs, Morgan Stanley, Credit Suisse, Nomura, Deutsche Bank, UBS. He borrowed from all of them at the same time. Each bank believed it was seeing the full picture. None of them were.
Only Hwang saw everything.
In a single year, he grew a $1.5 billion portfolio into $35 billion. His total assets were around $10 billion. His actual market exposure exceeded $50 billion.
The Crack
In March 2021, ViacomCBS announced a stock offering. The price collapsed. Alarm bells rang across Wall Street as banks suddenly realized they were all holding the same burning positions.
They demanded more collateral.
Hwang did not have it.
In a final attempt to save himself, he tried to buy more shares to prop up the falling prices. It failed. Margin calls kept coming from every bank at once.
What followed was a financial avalanche.
Banks began dumping enormous blocks of stock into the market. ViacomCBS fell 27 percent. Baidu dropped 33 percent. Tencent Music plunged 49 percent. The selling triggered more selling. Archegos had no floor.
The Reckoning
In two days, $20 billion, Bill Hwang’s entire personal fortune vanished.
But the damage spread far beyond him. In a single week, the collapse erased more than $100 billion in market value across nearly a dozen companies.
The banks were left with the wreckage.
Credit Suisse lost $5.5 billion, a blow so severe it shut down its entire prime brokerage division. It never recovered and collapsed entirely two years later.
Nomura lost $2.85 billion. Morgan Stanley nearly $1 billion. UBS $774 million.
The Fall
On July 10, 2024, a Manhattan jury found Bill Hwang guilty on 10 of 11 counts: securities fraud, wire fraud, conspiracy, racketeering, and market manipulation.
The boy from South Korea who built a $35 billion empire in silence, who prayed before markets opened, who drove a Hyundai while controlling the fate of global banks convicted.
As of early 2026, he was still seeking a presidential pardon.
The greatest trick Bill Hwang ever pulled was convincing five of the world’s most powerful banks that each one was the only lender he had.
Until the day they all discovered the truth at the exact same moment.
