At just shy of his 50th birthday, Yorkshire man John Flint is a lifer at the UK bank, having joined in 1989 as a management trainee after completing a degree in economics from Portsmouth Polytechnic.

He moved to Hong Kong during the same year and spent his 20s and early 30s moving around the bank’s Asian operations, with stints in India, Indonesia, Thailand and Singapore. He rose up the ranks to become head of Asian fixed income and derivatives trading.
