The data has been consistent for a decade. Women executives in financial services are 20% to 30% more likely to leave than women in adjacent industries (Oliver Wyman). 48% of women executives in the sector report burning out often or almost always (McKinsey). Every quiet exit at this level is institutional knowledge you cannot quickly replace, a client and team relationship at risk, another gap in a succession bench already short on women, and one more reason the representation numbers your board reports externally will not move.
And the cost starts long before anyone resigns. A proven performer running on empty is already delivering below the level that earned her the seat, and that gap sits on your most expensive, hardest-to-replace people.
Most interventions miss the cause. Empowerment programmes frame a structural problem as an individual deficit. Generic leadership development installs skills in the environment not optimized for them. Generic executive coaching makes your Managing Director spend the first month explaining her world to a coach who is never been in her shoes.
