Volkswacht Bodensee - Archegos founder jailed for 18 years for massive fraud: US media

In July, a jury in New York convicted South Korean-born Hwang on 10 of the 11 charges he faced and for which he could have been sentenced to spend the rest of his life in prison.

"The sentence has to reflect the seriousness of the event," said judge Alvin Hellerstein according to The New York Times, which also reported the 18-year prison sentence.

Hwang's family-owned hedge fund had taken huge bets on a few stocks with money borrowed from banks, and when one of those bets soured, the fund was unable to meet "margin calls" to cover the losses.

The subsequent collapse of the fund sent shockwaves through the markets and caused $10 billion in losses for Credit Suisse, Nomura, Morgan Stanley and other large financial institutions.

Credit Suisse was the hardest hit, losing some $5.5 billion, which further weakened the bank and pushed it close to bankruptcy in 2023 before it was taken over by its Swiss rival UBS.

During the case, the prosecution relied on two former Archegos executives, with one testifying that Hwang had instructed him to misrepresent the fund's finances.

The case came about after Archegos took stakes in several companies with the goal of driving up share prices, including in ViacomCBS, which is now Paramount Global.

At its peak in March 2021, Archegos was exposed to $160 billion through derivatives.

The plan worked initially -- almost quadrupling the value of ViacomCBS -- but quickly unraveled when that company announced a capital increase in 2021, triggering a sudden sell-off on Wall Street.

This started a domino effect that plunged the value of shares held by Archegos and in turn hit the banks that had provided funds to Hwang's firm.
