RBS Financial Markets, the capital markets division of the Royal Bank of Scotland, has hired Stewart Booth to fill the newly created position of head of credit trading. Booth joins from J.P. Morgan Securities and will be responsible for the investment-grade, high-yield and credit derivatives trading businesses, a RBS spokeswoman said. He will report to Symon Drake-Brockman, global head of capital markets, who previously had been covering credit trading as part of his overall duties. It could not be determined what his previous duties had been at J.P. Morgan. Calls to a J.P. Morgan spokeswoman seeking the name of Booth's replacement were not returned.
