China just reminded everyone who’s really in charge of its capital markets. Shares of Futu Holdings and Up Fintech Holding collapsed during US trading on May 22 after the China Securities Regulatory Commission announced penalties targeting offshore brokers that have been serving mainland Chinese clients without proper licenses.
The damage was immediate and brutal. Both FUTU and TIGR dropped between 30% and over 40% in a single session. Longbridge Securities, another offshore platform caught in the dragnet, also saw its shares plummet.
The fines and the fallout
Futu entities face proposed fines of approximately RMB 1.85 billion, roughly $271 million. Up Fintech is looking at RMB 308.1 million in fines on top of the confiscation of RMB 103.1 million in what regulators classified as illegal earnings.
The core accusation is straightforward. These platforms allegedly solicited customers in mainland China to trade securities on foreign exchanges without holding the necessary domestic licenses.
Mainland clients on these platforms are now locked into a two-year liquidation-only period. They can sell what they already own, but they cannot open new accounts or buy new positions.
The overall impact is staggering. Estimates suggest the crackdown could affect between HK$200 billion and HK$250 billion in assets held through these offshore platforms.
Why now, and why this hard
This crackdown didn’t come out of nowhere. The CSRC has been signaling displeasure with unauthorized cross-border brokerage activity since late 2022, when it first issued warnings about offshore platforms targeting mainland investors.
The broader motivation is capital control. China maintains strict rules about how money flows in and out of the country. These offshore brokers, by enabling mainland residents to invest in US-listed stocks, Hong Kong equities, and other foreign assets, effectively created a backdoor around those controls.
What this means for investors
If you hold shares in either company, the math just changed dramatically. A 30-40% single-day decline is the kind of event that reprices a stock for months, sometimes years. And unlike a typical earnings miss, this isn’t a problem the companies can fix with a better quarter.
Futu and Up Fintech built significant portions of their business on serving mainland Chinese clients. With that revenue stream now under direct assault, and with a two-year freeze preventing any new client acquisition from that market, the growth story that underpinned both stocks has a very large hole in it.
Futu has a presence in Hong Kong, Singapore, and other markets. Up Fintech similarly operates across multiple jurisdictions.
The two-year liquidation window suggests regulators are thinking in terms of a sustained wind-down rather than a one-time punishment. That timeline matters because it means forced selling pressure from mainland clients could weigh on these platforms’ assets under management for the foreseeable future.
