Asante Kwaku Berko, a former investment banking executive director at Goldman Sachs, has been convicted in a federal court in Brooklyn for his role in a bribery scheme involving multiple Ghanaian officials. The 30-year sentence looms over the former banker, who faces a maximum of 30 years in prison following the verdict. The jury found Berko guilty of conspiracy to violate the Foreign Corrupt Practices Act (FCPA) and money laundering. Judge Diane Gujarati oversaw the nine-day trial, which concluded yesterday, August 6.
The West African Power Plant Scheme
The scheme centered on a 2014 initiative to secure a deal between Goldman Sachs’ client, a Turkish energy firm, and the government of Ghana. The West African nation suffered from frequent blackouts. At that time, the country was grappling with a severe energy crisis.
Prosecutors allege Berko and his co-conspirators paid bribes to multiple government officials to ensure the Turkish company won the bid to build and finance a multimillion-dollar power plant. The payments were intended to grease the wheels of government approval for the project. Internal communications unveiled a complex network of exchanges. In April 2015, Berko and his team planned to transfer $1 million to the minister of power. Additionally, $5,000 was paid to five other officials during an all-expenses-paid trip to Turkey to inspect plant equipment. The inspection tour was presented as a technical review of the proposed infrastructure.

Evidence against the defendant included emails exchanged after the Ghanaian parliament approved the deal in July 2015, discussing the financial inducements at length. Beyond the structured payments, Berko personally paid tens of thousands of dollars in bribes to facilitate the arrangement. These digital records proved the existence of a coordinated effort to divert public funds for private gain.
While this prosecution highlights the pressure on financial institutions to monitor personnel abroad, it also exposes how quickly a company’s reputation can be damaged when employees exploit their positions to facilitate corruption. When an individual acts independently to secure business through bribery, the resulting fallout extends beyond legal penalties, forcing corporations to scrutinize their operations in regions where regulatory enforcement can be uneven.
Hiding the Payments and Legal Ramifications
To hide the scheme from Goldman Sachs and regulators, Berko utilized a mix of shell companies, fake invoices, nominee account holders, and cash withdrawals. The illicit funds were funneled through U.S. and foreign bank accounts, many of which were held in Berko’s name. The corruption concerns eventually led Goldman Sachs to pull out of the deal entirely, causing significant financial loss for the firm.

The legal process against Berko has been lengthy. He was extradited from the United Kingdom to the U.S. in July 2024, following his arrest in November 2022 on an Interpol notice. This international cooperation was essential in bringing the case to the American judicial system for prosecution.
This conviction adds to Berko’s existing legal troubles, which include a judgment from the U.S. Securities and Exchange Commission in June 2021. That judgment permanently barred him from breaching anti-bribery provisions and ordered him to return $275,000 in illicit gains plus interest. The SEC action signaled a strong stance against financial misconduct by former employees.
Assistant Attorney General Tysen Duva emphasized the department’s commitment to stopping such corruption. “We live in a global economy that American companies must be able to compete in fairly,” Duva said in a statement. “This defendant corrupted that fair competition.” Matthew Floyd of the FBI echoed this sentiment, noting that the agency will not tolerate dishonesty from anyone who disrupts the business market.
