WA man may not fight US extradition

A man wanted in the United States for his alleged involvement in global interest rate rigging is yet to decide if he will fight the extradition but a Perth court has still set a trial date.

Paul Dion Thompson, 49, was investigated over his alleged participation in one of the world's biggest financial swindles while he was working for Rabobank in Singapore between 2006 and 2011.

He is among several traders accused of manipulating the London Interbank Offered Rate, one of the world's key benchmark interest rates overseen by the British Bankers Association and representing about 200 banks from more than 60 countries.

In the Perth Magistrates Court on Wednesday a hearing date was set for June 2, but if Thompson decides not to fight the extradition the court hearing will be vacated.

After spending several days in Hakea Prison, Thompson was released in October on a $300,000 recognisance and $500,000 surety so he could care for his sick son.
