IWD26: Nana Esi Idun-Arkhurst: engineering systems, transforming banking

By Sandra Agyeiwaa OTOO

For Nana Esi Idun-Arkhurst, leadership has always been about building systems that work and developing people who can sustain them.

Though trained as a chemical engineer, she has spent more than two decades applying engineering thinking to Ghana’s banking industry.

“The principles of engineering – structured thinking, the scientific method and technical precision – are not confined to laboratories or production plants. They are equally powerful in boardrooms, credit committees and growth strategy sessions,” she mentioned.

Her journey into banking was not the expected path. With a strong background in chemistry and mathematics, she pursued a degree in Chemical Engineering and graduated among the top students in her class. Many assumed she would continue in academia or the industrial sector. Instead, she chose a different direction.

After completing national service as a teaching assistant in her department, she joined Standard Chartered Bank in 2003 through its International Graduate Programme. She was one of five participants in Ghana and the youngest and only woman in the cohort.

Looking back, she believes her engineering training gave her a strong foundation for business.

“Engineering teaches you how to break down complexity, identify root causes and design systems that work efficiently. Those are incredibly valuable skills in business and finance,” she revealed.

Her early years in banking included intensive global training and exposure to different areas of the business. She later earned a Master of Business Administration at the University of Edinburgh in Scotland as a Chevening Scholar.

“Studying subjects such as financial analysis, corporate strategy, mergers and acquisitions and entrepreneurship helped bridge the gap between my engineering training and business experience. It provided the theoretical structure behind what I had already begun learning on the job,” she explained.

Her career expanded internationally in 2013 when she moved to Dubai as Product Manager for Wealth Management for Africa and was later promoted to Director and Regional Head of Bancassurance for Africa.

The position involved negotiating multimillion-dollar partnerships with leading insurance companies, managing teams across ten markets in East, West and Southern Africa and working closely with executive leadership teams across the continent.

In 2016, Nana Esi was confronted with one of the defining choices of her career. When Fidelity Bank invited her to join as Director for Commercial and SME Banking, she had to balance the opportunities of continuing an international banking career with her desire to be more present in her children’s lives.

“I was very clear about the kind of upbringing and exposure I wanted my children to have and I realised that being constantly away was getting in the way of that so I chose family,” she said.

That same year, she joined Fidelity Bank as Director for Commercial and SME Banking, where she led a transformation of the business by restructuring teams, redefining performance metrics and strengthening the sales model. Her leadership journey has also involved navigating gender and age bias.

While at Fidelity,she also served as an Independent Non-Executive Director and Board Chair of Sanlam- Allianz  Life Insurance. Ghana Ltd.

According to Nana Esi, “I have often found myself leading teams or in board rooms where I am the youngest and the only female at the table. The battle against both gender bias generally and age bias within our African context has been real for me.  I have been called ‘that small girl.”

She explained that women in male-dominated leadership spaces face constant scrutiny, where qualities admired in men are often criticised in women. Despite such bias, performance remains the true measure of leadership.

By staying focused, prioritising people and balancing empathy with discipline and high expectations, she has shaped a leadership style grounded in trust, resilience and results.

Within eighteen months, the results were evident and she was promoted to Divisional Director for Retail Banking and subsequently handed the responsibility to lead the bank’s electronic banking business and business banking directorate as well.

In that role, she oversaw all retail segments, product development, sales channels, the branch network and agency banking.

Her approach was systematic and data-driven. She pushed for stronger use of analytics in decision-making, redesigned performance frameworks and invested heavily in building the capabilities of the retail team.

She also brokered a multimillion-dollar bancassurance partnership that transformed what had previously been a marginal business line into a major source of non-funded income within two years.

 

Under her leadership, the retail division consistently outperformed targets and grew into the bank’s largest strategic business unit by both revenue and balance sheet, exceeding one billion dollars.

Despite the scale of these achievements, Nana Esi believes her most meaningful impact lies elsewhere, in the people she has helped develop along the way.

Throughout her career, she has often been the youngest and only woman in leadership spaces, facing both gender and age bias. Traits admired in male colleagues are frequently criticised in women, yet her consistent results have proven that competence has no gender or age limit.

These experiences shaped her leadership style, balancing empathy, discipline, trust and high expectations while keeping people at the centre.

Her leadership philosophy revolves around three pillars: mindset, heartset and skillset.

She invests heavily in identifying and developing talent within her teams, helping individuals expand their thinking and build confidence in their abilities.

Many of her former team members, proteges and mentees have gone on to senior leadership roles across banking, fintech and other sectors.

Each year she intentionally develops a new skill or deepens an existing one. Recognising early the growing influence of technology on banking, she invested time in building her knowledge of data analytics, fintech and technology-driven business models.She also pursued a Masters in Information Technology Law from the University of Ghana School of Law. She also ensured her teams developed similar capabilities.

At one point, she sponsored more than forty members of her head office team to obtain business analysis and technology certifications so they could better engage in digital transformation projects.

She admits she has little patience for mediocrity or poor execution.

“My team knows they can always count on my support. But they also know that excellence is non-negotiable,” she stated.

One of the initiatives closest to her heart is the Ripples Leadership Hub, a non-profit organisation she founded to commemorate her twentieth anniversary in banking as a means of giving back.

Through the initiative, over 400 young women across eight countries in Africa and Europe have received mentorship and leadership development support from a network of experienced female professionals.

For Nana Esi, that ripple effect may ultimately be her most enduring legacy.

True to her engineering roots, she is not content maintaining existing systems.

She is now entering a new phase of her career focused on technology-driven business transformation.

In an era shaped by artificial intelligence and digital acceleration, she believes organizations must go beyond simply digitalizing processes.

She has been studying global entrepreneurs and technology leaders who are reshaping industries through AI and digital innovation, while also exploring new interests in behavioural science, neuroscience and the digital economy.

For her, the goal remains the same as it has always been:building systems that enable people and organizations to thrive.

As a business, once you truly understand who your customer is and the need you want to meet,” she says, “everything else becomes alignment.”

Outside the corporate world, she has also been pursuing a more personal vision – developing a farm with the aim of producing most of the food she consumes while learning more about the nutritional and medicinal value of local crops, herbs and spices. It is yet another example of the mindset that has guided her entire career: curiosity, systems thinking and a constant drive to build something meaningful.

She is currently a Certified Chartered Management Consultant and Founder, Ripples Leadership Hub.
