Citigroup has recruited a head of credit index trading in London amid continued sales and trading hiring across the investment banking industry as the business continues to drive revenues at bulge-bracket firms.

Haider Ali joined the US bank's London office this month from BNP Paribas, where he was European head of index trading. He will report to Tim Gately, head of credit trading in Europe, the Middle East and Africa at Citigroup, according to a person familiar with the hire.
