Hong Kong's securities regulator has designated broker SBCFX and several of its affiliated entities as unlicensed, following a trading collapse that left thousands of gold investors unable to recover their USDT holdings.

According to reports, the Securities and Futures Commission (SFC) added SBCFX, Star Bridge Capital Group, Star Bridge Capital Pty Limited, and Topical Wealth International Ltd to its alert list on August 28, along with the Chinese-language names 星橋資本 and 星橋資本集團. The warning links to the broker's website, sbcfx.com.

The alert list is one of the SFC's main tools for flagging suspicious websites and unregulated firms targeting Hong Kong investors, and it has repeatedly warned that fraudsters exploit the city's reputation as a financial hub to lend offshore operations an appearance of legitimacy.

The regulator's position is narrow but significant: according to the SFC, none of the identified parties are licensed or registered to carry out regulated activities in Hong Kong. Companies based outside Hong Kong are not permitted to advertise their services to Hong Kong residents without prior authorization.

The alert does not imply that fraud has occurred, nor does it invalidate any licenses the group may hold in other jurisdictions. It does mean, however, that Hong Kong clients dealing with these entities do not receive the protections normally afforded to customers of SFC-licensed firms, such as eligibility for the Investor Compensation Fund in covered situations.

The London gold blowup that triggered the alert

The designation arrived amid mounting controversy around SBCFX. Caixin Global reported on August 22 that investors and Hong Kong police had gathered at the broker's office in The Center in Central after a severe trading glitch triggered massive liquidations in London gold trading and wiped out thousands of retail investors' accounts.

Caixin estimated that roughly 3,000 investors from inside and outside mainland China could suffer losses from the incident.

The case fits a broader pattern of retail investors in the region being drawn to leveraged gold and foreign-exchange products marketed online, a segment regulators in Hong Kong and mainland China have warned about repeatedly. The failure highlights two growing challenges for regulators: the use of heavily leveraged algorithmic trading and the rising use of cryptocurrency deposits in the OTC derivatives market.

A further complication is determining which entity traders were actually dealing with. SBCFX marketed itself as the online brand of Star Bridge Capital and cites regulatory ties in Australia, South Africa, and Seychelles, according to reports. These include an Australian Financial Services Licence held by Star Bridge Capital Group Pty Ltd and a Seychelles dealer licence held by Topical Wealth International Ltd. The broker says the entity serving each client depends on where that client resides. Offshore licensing structures of this kind can leave clients with limited recourse, because a licence in one jurisdiction generally confers no rights or protections in another.

Recovering the deposits may prove difficult

The nature of the firm's operations also complicates any recovery of stablecoin deposits. Investors had opened leveraged positions using USDT, Tether's dollar-pegged stablecoin, and stablecoins that are not held at a regulated institution can be difficult to retrieve once something goes wrong. Hong Kong has been rolling out a licensing regime for virtual asset platforms, but deposits held with unlicensed offshore brokers fall outside that framework.

A report published in March 2026 by the Financial Action Task Force addressed this problem. Stablecoin transfers conducted peer-to-peer through unhosted wallets do not involve any regulated Virtual Asset Service Providers between the transacting parties, and issuers are sometimes unable to monitor transactions across blockchains.

At the same time, the very features that make USDT suitable for cross-border trading accounts can also complicate asset freezing or tracing when investors seek to recover their funds.

Even when a stablecoin issuer is able to intervene, recovery is not automatic. Tether states that it has assisted in freezing assets worth over $4.4 billion while cooperating with more than 340 law enforcement agencies across more than 65 countries.

Cryptopolitan cited a report examining 2,955 Tether freeze incidents, published on August 6. It found an average delay of more than two hours between the time a freeze was proposed and when it was executed on-chain. Roughly $20.4 million worth of USDT was transferred by more than sixty addresses ahead of the freeze — effectively written off.

For many traders attempting to salvage assets held in foreign accounts, this leaves considerable uncertainty over whether their funds can be retrieved. The key point from Hong Kong's SFC is that none of the names in its August 28, 2026 alert is licensed or registered with the SFC. Overseas licenses do not amount to licensing by Hong Kong's regulator. The SFC's August 28 alert explicitly states that all five names — including SBCFX and the three corporate names — are not licensed or registered with the SFC for regulated activities.
