The U.S. Department of Justice indicted a former JPMorgan Chase & Co. trader on charges of conspiracy to fix currency prices on several market currencies, the Financial Times reported May 10.

Akshay Aiyer, who worked at JPMorgan from 2006 until 2015, is accused of conspiring with other traders to fix prices on the South African rand, Russian ruble and other emerging-market currencies, according to the publication.

In 2015, JPMorgan was one of the banks that agreed to plead guilty to antitrust violations in connection with manipulating foreign exchange markets.
