Three former traders at Dutch lender Rabobank were criminally charged on Monday with manipulating the Yen Libor benchmark interest rate, the U.S. Department of Justice said.
Two former Japanese Yen derivatives traders and a third trader responsible for setting the bank's Yen Libor rate were accused of submitting fraudulent rates in order to benefit their trading positions, the Justice Department said.

In October, Rabobank paid $1 billion to resolve U.S. and European probes into rate-rigging allegations, making it the fifth bank punished in the scandal that has swept the industry.
A federal judge in New York signed a criminal complaint charging Paul Robson, a senior trader in London; Paul Thompson, who ran a trading desk in Singapore; and Tetsuya Motomura, a senior trader and supervisor on the bank's Tokyo desk, the department said. Charges included wire fraud and conspiracy to commit wire fraud, it said.

Robson, Thompson, and Motomura could not be immediately reached for comment.
The Libor rates that oil the wheels of global finance are an average rate at which a panel of banks say they could borrow money. The manipulation of related benchmarks has resulted in $3.7 billion in fines to date.
