Chinese regulators review Jane Street's trading patterns in the China ETF market

There are rumors that Chinese regulators are reviewing Jane Street's trading behavior in the Chinese ETF market. However, a person close to Jane Street stated, "We are unaware of these rumors and have no reason to believe they are true; these rumors should not be associated with Jane Street."

This week, Jane Street and its co-founders, along with two employees, were accused of insider trading, fraud, and market manipulation, actions that have been linked to the accelerated collapse of the 2022 TerraUSD (UST) stablecoin and its sister token Luna, resulting in a loss of $40 billion in value. Founded in 1999, Jane Street is one of the largest proprietary quantitative trading firms in the world, with net trading revenues exceeding $20 billion in 2024 and net profits nearing $13 billion. Unlike hedge funds, Jane Street does not accept external client funds, so its disclosure obligations are far lower than those of traditional asset management institutions, a structure that has kept it shrouded in mystery for a long time.
