The illicit payments connected to fraudulent letters of credit and collateral papers featuring a collective stated worth greater than $1.6 billion.
An ex-relationship manager for China Construction Bank (Asia) has been sent to prison for four years in Hong Kong following his acceptance of over $470,000 in Tether (USDT) bribes. The payments were taken to verify bogus financial paperwork exceeding $1.6 billion in value.
Thirty-two-year-old Lam Chun-yin received his sentence at Hong Kong’s District Court on September 18 after admitting guilt to plotting with a financial technology company employee and additional partners to take bribes. The Independent Commission Against Corruption (ICAC) reported that the digital asset transactions surpassed US$470,000, which translates to roughly HK$3.7 million. Additionally, Lam was instructed to pay back approximately HK$3.7 million to CCB Asia.
Taking place between April and June 2022, the operation involved Tether transfers given to validate multiple standby letters of credit (SBLCs) incorrectly purported to originate from CCB. Furthermore, two collateral letters were wrongly presented as being issued by Yu Po Holdings and endorsed by CCB. Together, these financial instruments held a stated value surpassing US$1.6 billion.
False CCB Documents Tied to Vesttoo Investment Scheme
Lam served as a relationship manager within CCB Asia’s consumer banking division stationed at the Causeway Bay retail branch. The ICAC noted that he lacked any authorization to handle business credit facilities or letters of credit. Even so, he acted as a CCB contact tasked with issuing SBLCs for Yu Po Holdings, a firm that entered the market as an investor via the fintech company Vesttoo during early 2022.
Vesttoo maintained an infrastructure for insurance-oriented investment transactions where participants needed to supply bank-provided SBLCs as security. According to the ICAC, Lam collaborated with a Vesttoo department head alongside associates to validate the fabricated paperwork.
An internal audit by CCB Asia brought the situation to light. Afterward, the institution escalated the issue to the ICAC and cooperated with the inquiry. Investigators established that neither CCB nor its affiliated entities produced the SBLCs or collateral letters in question.
This matter connects to the broader failure of Vesttoo, which sought bankruptcy protection in 2023 once officials uncovered the fraudulent collateral records. Subsequent fallout has generated legal battles involving banks, insurance providers, and other stakeholders across the insurance sector.
During the sentencing, Judge Ernest Lin Kam-hung stated that utilizing forged banking documents placed CCB in substantial potential jeopardy while damaging Hong Kong’s standing as a global financial hub. The magistrate initially handed down a six-year term prior to reducing it by one-third due to Lam’s guilty plea.
