China Offshore Crackdown: Tiger, Futu Hit With $330M Fines

The China offshore crackdown just moved from warning shots to live fire. Tiger Brokers will block deposits and new buy trades on all mainland China accounts from June 12, days after parent company UP Fintech disclosed a $59.7 million penalty from the China Securities Regulatory Commission. Add the proposed $271 million fine against rival Futu Securities and Beijing has now put roughly $330 million of penalties on the table in a matter of weeks.

HONG KONG, China — 05 June 2026

The CSRC announced on May 22 that it would penalize Tiger Brokers (NZ) Limited, Futu Securities International (Hong Kong) Limited and Longbridge Securities (Hong Kong) Limited for running cross-border securities, fund and futures business in mainland China without onshore licences. All three firms get a two-year grace period to wind down. Existing mainland clients can sell holdings, withdraw funds or close accounts. That is it. No new money in, no new positions.

For two decades these platforms were the quiet workhorses of Chinese capital flight, letting mainland residents buy Hong Kong and US stocks from a phone app. Bloomberg has described the campaign as the largest cross-border enforcement operation China has run in decades, and it lands squarely on the offshore account strategies of millions of investors.

CSRC Fines Reach $330 Million Across Three Brokers

The numbers are brutal. On June 2, UP Fintech told shareholders that the CSRC’s Beijing bureau had ordered penalties and confiscation of illegal gains totalling roughly RMB 411 million, about $59.7 million, against several of its subsidiaries. The company booked it as a significant event for the first quarter and reported a $26.9 million net loss for Q1 2026.

Futu got it worse. Not even close. The CSRC and its Shenzhen bureau propose to confiscate gains and impose fines of approximately RMB 1.85 billion, around $271 million, on Futu entities, plus a personal fine of roughly $183,575 on founder and CEO Li Hua. Futu says mainland clients account for about 13% of its funded accounts. Its shares dropped by a third in the five days after the announcement.

Tiger Brokers Freezes Mainland Deposits From June 12

The freshest development came this week. According to a client notice reported by financial industry publication Caproasia on June 4, Tiger Brokers will stop accepting deposits and new buy orders on China mainland accounts from June 12, 2026. Affected clients keep three options: sell existing holdings, withdraw funds, or close the account. The two-year grace period the CSRC granted is a runway for liquidation, not a reprieve.

Hong Kong’s banking system is moving in step. The Hong Kong Monetary Authority has reportedly told banks to apply extra measures when opening and managing investment accounts for mainland residents, a development first reported by Chinese-language outlets and echoed across the regional financial press. Anyone who watched the EU push its CRD VI banking rules onto non-EU banks will recognise the pattern: regulators no longer stop at their own borders.

How CRS Powers the China Offshore Crackdown

Here’s the kicker. None of this enforcement would be possible without the OECD’s Common Reporting Standard, which automatically feeds foreign account data to Chinese tax authorities. Tiger reports through New Zealand. Futu reports through Hong Kong. Both jurisdictions exchange data with Beijing every year, and Bloomberg reports that tax bureaus have used that data to send back-tax notices to wealthy residents, in some cases reaching back to 2018.

China taxes residents on worldwide income, including a 20% rate on overseas investment gains. From mid-2025 onward, notices started landing with investors who held Hong Kong and US stocks through offshore apps. The brokers became the choke point. Switzerland learned a similar lesson when its transparency register tore up decades of banking privacy. Bottom line: a CRS-reporting brokerage account was never private, and Beijing just proved it at scale.

What the China Offshore Crackdown Signals for Global Investors

This is not just a China story. Thailand is running an AI-powered nominee crackdown of its own, and governments from Madrid to Canberra are mining exchanged account data for revenue. The toolkit is the same everywhere: data exchange first, broker pressure second, retroactive tax bills third. The clock is ticking for anyone whose structure depends on a regulator’s patience.

The era of casual offshore investing through a phone app is over for mainland China, and the enforcement model behind the China offshore crackdown is now proven, profitable and exportable. If your wealth strategy still assumes regulators move slowly, this was your wake-up call. Review your structure, check where your data flows, and look at residency options that put you on the right side of the reporting rules before the next campaign starts.
