US Man Sentenced to 5 Years for $97 Million Oil Scam Linked to

Geoffrey Auyeung, a 47‑year‑old Washington resident, received a five‑year federal prison sentence on June 9 2026 after pleading guilty to conspiracy to commit money laundering for a $97.1 million oil‑investment fraud that routed funds through Binance cryptocurrency accounts controlled from Nigeria and Russia [1].

Scheme mechanics and crypto flow

Between June 2022 and July 2024, Auyeung and co‑conspirators marketed fake oil‑storage investments in Rotterdam and Houston, promising high returns from leasing depot capacity. They created at least nine shell entities and opened 81 bank accounts at 24 institutions to receive investor money, amassing $97.1 million in wire transfers and deposits [1]. Once the cash entered Auyeung’s control, it was quickly redistributed: some moved offshore, many were converted into cryptocurrency and sent to Binance accounts tied to individuals in Nigeria and Russia. In total, Auyeung maintained 19 accounts across eight exchanges, with Binance being the primary conduit for the illicit crypto proceeds [1].

Sentencing, forfeiture and ongoing misconduct

Auyeung pleaded guilty in February 2026 and was sentenced by U.S. District Judge John Coughenour, who noted the defendant “had every reason to know there was something wrong here” and continued to take commissions after indictment [1]. The court ordered him to forfeit roughly $2.3 million in seized cash, an Audi SQ8, about $7.1 million in cryptocurrency wallets, and an additional $300 000 held in bank accounts for restitution [1]. Prosecutors highlighted that Auyeung kept directing new deposits through accounts registered in his wife’s name, netting an extra $400 000 in commissions after his indictment, bringing his total earnings to at least $4.08 million [1].

Enforcement implications for crypto platforms

The case underscores U.S. law‑enforcement focus on cross‑border crypto money‑laundering. Binance, the world’s largest crypto exchange, was identified as the gateway for the illicit funds, though the exchange itself was not charged. The investigation, led by the U.S. Immigration and Customs Enforcement and the Seattle HSI, demonstrates that crypto wallets can be traced and linked to traditional financial fraud, reinforcing the need for robust AML controls on exchanges operating in high‑risk jurisdictions [1].

What to watch

• Regulatory scrutiny: Expect heightened U.S. AML examinations of Binance and other exchanges with significant activity from Nigeria and Russia.
• Future forfeiture actions: Additional asset seizures may follow as authorities continue to unwind the crypto proceeds linked to the scheme.
• Legal precedents: This sentencing could serve as a reference point for future prosecutions involving crypto‑facilitated investment fraud.

The sentencing sends a clear signal that crypto‑enabled money‑laundering will attract serious penalties, and it highlights the growing intersection of traditional financial fraud with digital‑asset platforms. The case leaves open how aggressively regulators will pursue similar cross‑border crypto flows in upcoming investigations.
