The International Business Times reports that the 52-year-old woman, named only as Lydia, jumped from the bank's riverside headquarters at approximately 10am on Tuesday, according to France TV and Le Parisien.
She reportedly questioned her superiors before the lethal plunge, a claim the bank refuted, adding she had been in therapy for several years.
The bank circulated an email confirming the suicide, adding it was a 'very painful moment for the company'.
Lydia, who is thought to have lived alone, was described as 'secretive' but 'very well known and popular' and had a good relationship with staff.
