The Financial Conduct Authority (FCA) has banned Lee Stewart, a former trader at Rabobank from the UK financial services industry for lacking honesty and integrity following a criminal conviction for fraud in the US.

In March 2015 Stewart pleaded guilty in the US for his role in a conspiracy to manipulate Rabobank’s US Dollar Libor submissions.

This action follows the recent ban of Paul Robson, another trader at Rabobank. To date the FCA has issued 14 warning notices related to interest rate benchmarks, and continues wider investigations into individuals’ conduct in relation to Libor misconduct.

Georgina Philippou, acting director of enforcement and market oversight at the FCA, said: “Mr Stewart was an experienced trader at Rabobank who, through his guilty plea, has admitted to participating in a criminal conspiracy to manipulate Libor over a prolonged period of time. His behaviour was inexcusable and very serious.

“This ban further reinforces our expectation that individuals and firms take responsibility for ensuring market integrity and reminds them of the consequences if they fall short of our standards.”
