Markets are mourning Cassandra Seier, who passed away this weekend.
Throughout her almost 30-year career, Seier held numerous senior roles and she spent more than 23 years with Goldman Sachs. During her time at the firm, she was a managing director, overseeing electronic execution, clearing sales and over-the-counter clearing sales functions.
She joined NYSE in 2022 as head of international capital markets.
NYSE commented: “We are devastated by the news that our colleague Cassanda Seier passed away over the weekend. She was integral to our team, and an incredibly strong, vibrant member of our NYSE community. Our thoughts are with her family during this difficult time.”
NYSE Group president Lynn Martin added, via LinkedIn, “[Seier] embodied everything that makes the NYSE team great – a tireless defense of the principles she believed in and a fierce champion of every single customer she touched.
“To know her was to know that she had endless energy – she was someone who was laser focused on getting a job done but always found time to offer anyone support and to mentor the next generation of leaders. To say I admired her would be an understatement – stood in awe might be a better expression.”
Seier was also chairwoman of the World Federation of Exchange’s listings working group and CEO and president of the non-profit organisation, Women in Financial Markets (WIFM).
In a post on LinkedIn, WIFM shared: “Her legacy is woven into every part of our organisation through the programs she championed, the community she nurtured, and the opportunities she created for thousands of women. We all looked up to her. We always will.”
