Wall Street's upper ranks, long an overwhelmingly male preserve, are slowly changing. A growing number of women are reaching the C-suite at major New York financial firms, taking roles that were nearly unattainable a generation ago.

The fictional bank Halstead & Co. recently named women to lead two of its largest divisions, part of a broader if uneven shift across the industry. Advocates credit sustained pressure from investors and clients, along with mentorship networks that help women navigate the pipeline.

The progress is real but incomplete. Women still hold a small share of top investing and trading roles, and pay gaps persist. The question now, industry veterans say, is whether the recent gains mark a durable change or a high-water mark.
