How a series of calculated risks led a BNY executive to the C-suite of America’s oldest bank

In the high-stakes theater of global financial services, leaving a 26-year run at a blue-chip firm for the uncertainty of a pandemic-era IPO would strike most executives as reckless. For Cathinka Wahlstrom, it was instinct.

Now chief commercial officer at Bank of New York (BNY), Wahlstrom’s leap from Accenture partner to the C-suite of the oldest bank in the United States offers a study in modern leadership that blends vision and comfort with uncertainty and growth.

Her career is defined by inflection points. She left Accenture at the height of her influence. She moved across continents more than once. She declined a role in Japan when her children were young, then later agreed to take a private-equity-backed company public in the middle of a global crisis. Each decision reflected a consistent trade-off between certainty and growth.

Wahlstrom joined Accenture when it still operated as a partnership. As the firm evolved into a global public company, her role expanded alongside it. What began as deep technical work in financial services grew into stewardship of major client relationships and leadership roles that required her to think across markets, cultures, and organizational layers. She learned to operate inside complex systems where decisions ripple through clients, teams, and institutions.

Over time, her work shifted from solving siloed problems to understanding interdependence and how choices in one area increasingly shape outcomes in another. She could see her future with unusual clarity, including the shape of the work and the progression ahead.

“I could see my next ten years at Accenture,” Wahlstrom says. “And I just knew I was ready for the next thing—even though I couldn’t quite see what that next thing was yet.” 
​​That clarity signaled mastery, she says. Staying would have meant optimizing what Wahlstrom already knew, whereas leaving would have meant embracing the vulnerability of a new learning curve.

The opportunity arrived during the pandemic in the form of a chief commercial officer role at a Blackstone-backed company preparing to go public, a role Wahlstrom says tested her in a different register: less advisory and more ownership of outcomes.

That experience set the stage for what came next. When BNY approached her, the challenge was fundamentally different. Founded in 1784, the bank’s defining strength is longevity. Wahlstrom was recruited with a mandate to modernize without destabilizing. Her task was to upgrade technology, evolve culture, and expand the bank’s relevance to a younger client base while preserving the foundations that have enabled the institution to endure for nearly 240 years.

Today, Wahlstrom says she works at the seams of the organization where data meets judgment, strategy meets execution, and global plans meet local realities. One example is using AI to better understand the client experience, surface friction points, and identify emerging opportunities. 

Viewed in sequence, Wahlstrom says her career has moved from stability to uncertainty and then to renewal. That arc, she says, reflects what leadership increasingly demands: the ability to live inside paradoxes. Leaders must hold vision and detail at the same time, pair analytical rigor with emotional intelligence, and think globally while acting locally.

“I’m really driven by that journey of setting a vision, coming up with a plan, and then executing,” Wahlstrom says. “I just love the process.”
