There¡¯s a particular telephone conversation that HSBC Global Chief Economist Janet Henry has down pat.

Here¡¯s how it goes: ¡°You get a call from a headhunter,¡± she says. Then Henry inevitably finds herself saying, ¡°No, I¡¯m not interested.¡± But it doesn¡¯t end there. ¡°They always say, ¡®Do you know anyone that might be?¡¯ I give them men¡¯s names because I¡¯m always curious to see if they¡¯ll say ¡ª and they do say ¡ª ¡®Yes, but do you know any women?¡¯ ¡±

As one of a handful of women leading economic research departments at global banks, Henry is well-positioned to observe the recent shift in demand for greater gender diversity within her profession. She looks back on her own experience as she sips tea from a disposable cup in a noisy cafe at HSBC Holdings PLC headquarters in London¡¯s Canary Wharf. When she joined the bank in 1996, she was the only woman on its global economics team. Now women account for 13 of her 39-strong global group.
