Chinese police bust 1.9 billion USDT banking operation
In a major crackdown, the Chengdu Public Security Bureau announced on May 15 the dismantling of an extensive underground banking network, resulting in the arrest of 193 suspects across China in an operation that unveiled illegal businesses using the U.S. dollar stablecoin, Tether (USDT).

Unauthorized foreign exchange settlements
These activities involved illicit transactions amounting to approximately 13.8 billion yuan ($1.9 billion). The investigation began in November 2022 when authorities detected suspicious activities involving underground banks in Chengdu’s Longquanyi district. In response, a specialized task force was formed, integrating experts from various police departments, including economic investigation, cyber security and legal affairs. This team uncovered unauthorized foreign exchange settlements that bypassed national regulations.
On June 1 of last year, acting on instructions received from the Ministry of Public Security, the task force conducted coordinated raids in several major cities, such as Shanghai and Shenzhen. These efforts led to the capture of key figures in the criminal syndicate, involving the arrest of 25 suspects. Law enforcement seized numerous bank cards, payment instructions and other digital payment instruments tied to the illegal operations during these raids. A broader investigation across 26 provinces has resulted in 193 suspects being arrested.
Using USDT to evade regulation
Further investigations revealed that since January 2021, the syndicate exploited its import and export business to facilitate illegal activities. By using USDT as a medium, they bypassed official foreign exchange channels to service clients needing to transfer funds internationally. Moreover, these operations were intricately linked to other illicit activities, including financial fraud and smuggling.
In a related development, on May 13, BeInCrypto reported that the Chinese government arrested six individuals responsible for illicit crypto transactions worth $295 million. These arrests highlight the challenges and risks associated with cryptocurrency in unregulated environments.
Additionally, the Hong Kong police recently apprehended three men at a currency exchange shop following a deceptive transaction involving Tether’s USDT. The suspects allegedly showed a customer ceremonial "hell money" before deceitfully persuading him to transfer about $128,073 worth of USDT, only to refuse the agreed-upon cash exchange afterward.
According to the South China Morning Post (SCMP), hell banknotes are a form of ceremonial paper money burned as an offering to ancestors or deities in traditional Chinese culture.
Late last year, USDT was used by a gang of gold smugglers in Nepal, who received $16 million in the Tether stablecoin in exchange for the precious metal. A joint investigation carried out by the authorities in Nepal and China led to the arrest of two Chinese and 13 Nepalese nationals in connection with the illicit activity.
Over the course of the weekend, it emerged that two Chinese nationals had been charged by the authorities in the United States with money laundering through Bahamas-based Deltec Bank. Deltec acts as the primary banker for Tether, prompting longstanding Tether critics to suggest illicit activity relative to the stablecoin issuer’s dealings with the bank.
This series of arrests and discoveries underscores the ongoing efforts of Chinese authorities to clamp down on illegal cryptocurrency activities. The activity also poses problems for Tether in its efforts to maintain compliance and stamp out illicit use in the face of ever-increasing regulatory scrutiny worldwide.
