Highlights
- Shanghai police dismantled an underground banking network accused of moving nearly 20 billion yuan (about $2.8 billion) using crypto.
- Nineteen suspects were arrested in the main case, which allegedly ran since August 2024.
- A second, related case involving a virtual-card payment platform moved over 200 million yuan and led to nine more arrests.
- Shanghai police say they've now busted crypto-linked economic crime cases worth over 20 billion yuan and arrested more than 70 suspects in 2026 alone.
- The bust follows the PBOC's Shanghai branch reaffirming a hardline stance on crypto speculation earlier this month.
Shanghai police announced they have dismantled a large underground banking operation that allegedly used cryptocurrency to facilitate illegal cross-border currency exchange worth nearly 20 billion yuan, roughly $2.8 billion, according to a report by The Paper cited by PANews. Nineteen suspects were arrested. Investigators say a group led by a suspect surnamed Liu had, since August 2024, used cryptocurrency as a settlement medium, converting yuan into crypto and then into foreign currency through a “yuan-to-crypto-to-foreign-currency” roundtrip, charging clients a service fee for each transaction. In a related case, Shanghai police separately broke up a group that built a platform for cross-border settlement and issued virtual credit cards, using crypto top-ups and multi-currency conversion to generate illicit profit; that operation moved more than 200 million yuan and resulted in nine additional arrests.
Part of a Broader 2026 Enforcement Push
Police said the two cases are part of a wider campaign: Shanghai authorities have now cracked multiple new-type economic crime cases tied to virtual currency in 2026, arresting over 70 suspects with total case value exceeding 20 billion yuan. The action lands weeks after the Shanghai branch of the People's Bank of China used its second-half 2026 work conference, held August 4, to reaffirm its commitment to suppressing crypto speculation and preventing systemic financial risk, part of a sustained escalation that has also seen Chinese regulators extend enforcement to stablecoins and asset tokenization earlier this year. China has maintained a blanket ban on domestic crypto trading since 2021, but enforcement volume and case size have both grown as authorities target the “yuan-crypto-forex” conversion loop specifically, rather than simple peer-to-peer trading.

At roughly $2.8 billion combined, this bust sits well above the typical underground-banking case China's police report publicly, and it's notable that both schemes leaned on cryptocurrency as the settlement layer rather than traditional trade-invoice mispricing or shell-company wires, the older playbook for moving capital out of China. Crypto's appeal for these networks is straightforward: stablecoins and major tokens can be moved across borders near-instantly and outside the correspondent-banking system that regulators and banks monitor for suspicious activity, making them attractive to operators seeking to bypass China's capital controls at scale. The case also illustrates a recurring pattern in China's enforcement data this year — a steady drumbeat of billion-dollar-plus cases rather than isolated incidents, consistent with what industry trackers describe as an enforcement surge through 2026.
What to Watch Next
Shanghai police did not indicate whether further arrests are expected, but the case is likely to feature in China's next round of official statements on financial risk prevention, and could inform how aggressively regulators police stablecoin-based settlement specifically as that vector draws more scrutiny. For global crypto markets, the read-through is less about price impact and more about durability of demand from mainland Chinese capital flight, a flow that regulators are visibly working to choke off case by case rather than through a single blanket policy change.
