China launches its largest cross-border tax investigation in decades, fining Futu and Tiger over 2.2 billion RMB — will cryptocurrency become a pressure outlet?

Chinese authorities have simultaneously cracked down on three offshore brokerages — Futu, Tiger Brokers (a subsidiary of Up Fintech), and Longbridge Securities — citing "illegal cross-border securities operations," with proposed penalties (fines and confiscations) totaling over RMB 2.26 billion.

In late May, the China Securities Regulatory Commission, the People's Bank of China, the Ministry of Public Security, and five other departments — eight in total — jointly released the "Comprehensive Implementation Plan for Rectifying Illegal Cross-Border Operations in Securities, Futures, and Funds," planning a two-year concentrated rectification period to comprehensively sweep away unauthorized offshore investment services. At the same time, regulators announced enforcement actions against Futu Holdings, Tiger Brokers, and Longbridge Securities, on the grounds that all three are suspected of operating in mainland China without licenses. After the news broke, Futu's U.S.-listed shares plunged nearly 30% in a single day, while Up Fintech (Tiger Brokers' parent company) ADRs at one point dropped roughly 47% in pre-market, dragging down several other U.S.-listed Chinese stocks and causing severe turmoil across the entire ecosystem. According to the CSRC announcement on May 22, 2026, the scale of the proposed penalties is staggering: - Futu Holdings: Fines and confiscations totaling approximately RMB 1.85 billion, with founder and CEO Leaf Li Hua personally fined an additional RMB 1.25 million. - Tiger Brokers (Up Fintech): Fined approximately RMB 308.1 million, with an additional confiscation of illegal gains of approximately RMB 103.1 million, totaling roughly RMB 411 million. - Longbridge Securities: Also on the rectification list, with specific amounts yet to be announced. CITIC Securities estimates that the rectification campaign could impact up to HK$250 billion (approximately US$32 billion) in Hong Kong assets, with Futu alone potentially accounting for over HK$180 billion. According to Bloomberg, the eight-department plan reveals strict transitional arrangements: during the two-year concentrated rectification period, offshore institutions are prohibited from providing any buy-in or fund transfer-in services to existing domestic investors — only one-way selling and fund withdrawals are permitted. After the rectification period ends, they must completely shut down domestic websites, trading software, and servers, and fully withdraw from the mainland Chinese market. Both Futu and Up Fintech have publicly stated they will cooperate with the authorities' investigation. Hong Kong regulators subsequently followed up, announcing they will strengthen scrutiny rules for mainland Chinese investors opening accounts, and explicitly cited money laundering risks. Several major Chinese banks in Hong Kong have also suspended opening investment and wealth management accounts for mainland residents, and raised the threshold for savings account applications. Christopher Marquis, Professor of Chinese Management at Cambridge University, bluntly told Bloomberg: "Providing offshore services to wealthy Chinese clients is now a much more complicated and much higher-risk business. Those actively working with high-net-worth Chinese clients are all worried they could be the next Tiger, Futu, or Longbridge." Information obtained by Bloomberg further shows that this rectification campaign is not limited to brokerages — well before the public announcement, Chinese tax authorities had already launched private investigations in Beijing, Shanghai, Guangzhou, and other cities. Those summoned typically held assets exceeding US$30 million, many of them ethnic Chinese with foreign passports who had returned to settle in China, with some managing their wealth through offshore trust structures. These individuals were required to pay up to 20% in back taxes on investment gains, potentially with late penalties added, with audits traceable back to at least 2018. Bloomberg notes that this process involves no official notification — only private negotiations between tax authorities and individuals — and in extreme cases, even threats of police intervention have been used to apply pressure. The impact extends to the institutional side as well. According to law firm DLA Piper, when foreign capital exits investments in mainland Chinese assets via the Qualified Foreign Limited Partner (QFLP) structure, the capital gains tax rate has quietly been reinterpreted by local authorities from the original ~10% withholding tax to a 25% corporate income tax — more than doubling the rate, with some cases applied retroactively. This rectification has a deeper fiscal logic. Bloomberg notes that local governments have long relied on land sales as a primary revenue source, but between 2021 and 2025, real estate-related revenue collapsed by approximately 48%; Chinese home prices have also fallen by about one-third from their 2021 peak. Under this pressure, although national personal income tax revenue hit a record high last year of RMB 1.62 trillion (up 11.5% year-on-year), the fiscal gap remains difficult to close, forcing authorities to turn their attention to offshore assets. Ironically, the very thing driving the wealthy to flee and move money overseas is precisely China's own real estate crisis. Luis, an employee at a Shanghai-based advisory firm who holds accounts with both Futu and Longbridge, candidly told Bloomberg: "What can I do in China? Buy a house and shoulder a 30-year mortgage, watching home prices keep falling?" Another wealthy investor, Zhuang, told Bloomberg he doubled his assets over the past year trading U.S. stocks, but is no longer willing to bear the regulatory risk — choosing to liquidate his positions and rotate into A-shares. Bloomberg cites the Institute of International Finance (IIF) estimating that China's capital outflows last year totaled approximately US$807 billion, a record high. For the crypto space, there is an angle to this rectification that cannot be overlooked. Wealthy Chinese citizens have long used "underground exchanges and cryptocurrencies" to bypass the US$50,000 per-person annual foreign exchange limit. Now that compliant cross-border brokerage channels such as Futu, Tiger, and Longbridge are being forcibly narrowed, mainland investors seeking portfolio diversification — lacking other low-friction exits — may see some demand shift further toward cryptocurrencies and stablecoins. As for the scale, that remains to be validated by subsequent data.
