The deputy head of inflation trading at RBS has quit ahead of a move to Citigroup, in the latest example of a North American bank operating in Europe picking off talent from the UK bank's fixed income business.

Ian Hale resigned from RBS last week, according to two sources familiar with the situation, and will join Citi after a period of gardening leave, according to the sources. Hale did not respond to messages seeking comment in time for publication.
