Citi has made three hires in its FX options business. Charlie Cernosia will join the yen options trading team in April as a director from Lehman Bros in New York; Nathan Swami also joins the yen team in April from the same bank, but this time in Singapore, and with the same rank. According to Nigel Khakoo, Citi’s head of G10 options trading, Swami’s technical proficiency will help further develop the bank’s exotics platform. Finally, Citi has hired Neil Boston in its options technology team as director and chief technical architect. Boston has the task of building the bank’s next generation of pricing and risk management systems. His previous role was at Merrill Lynch; he is due to start at Citi on May 5.
