Thomas Hayes, a former trader at banks including UBS Group AG and Citigroup, on Aug 3, 2015. Tom Hayes, the first trader jailed worldwide for interest rate rigging, lost his appeal against his conviction in a London court on Wednesday. Hayes, a former star Citigroup and UBS trader, was convicted in 2015 of conspiracy to defraud by manipulating Libor, a benchmark rate once used to price trillions of financial products globally. His appeal against his conviction was heard alongside that of Carlo Palombo, a former Barclays trader convicted in 2019 of skewing Libor's euro equivalent, Euribor. Hayes and Palombo were given 14 days to apply for permission to appeal to the Supreme Court.
