Segun Agbaje grew up surrounded by influence, intellect, and ambition. Yet his journey to becoming one of Africa’s most respected banking executives was not handed to him. It was earned through discipline, strategy, and a deep understanding of financial systems.

Today, he is widely recognized as the driving force behind the transformation of Guaranty Trust Bank into a modern banking giant and later the leader of its parent company, Guaranty Trust Holding Company.

Early Life and Global Exposure

Segun Agbaje was born on March 28, 1964, into a prominent Nigerian family. His father, the late Chief Julius Agbaje, was a banker and businessman, and his mother, Margaret Agbaje, became a notable political figure in Lagos State.

Education was a priority in his upbringing. He studied Accounting at the University of San Francisco and later earned a Master of Business Administration from the University of San Francisco as well.

This international exposure gave him a global perspective on finance and corporate governance.

Early Career and Entry Into Banking

Before returning to Nigeria, Agbaje worked at Ernst and Young in the United States. The experience sharpened his financial analysis and auditing skills.

He joined Guaranty Trust Bank in 1991, not as a ceremonial figure but as a working professional. GTBank itself was still young at the time, having been founded in 1990 by visionary bankers including Fola Adeola and Tayo Aderinokun.

Becoming Chief Executive

As Nigeria moved toward a more cashless economy, GTBank positioned itself at the forefront of fintech integration. The bank launched innovative digital products that simplified transactions for individuals and businesses.

Agbaje understood that the future of banking was not only in physical branches but in technology.

Transition to Holding Company

In 2021, GTBank restructured into a holding company model known as Guaranty Trust Holding Company. Segun Agbaje became the Group Chief Executive Officer.

This shift allowed the institution to expand beyond traditional banking into other financial services such as payments, asset management, and insurance.

It marked a new phase of growth and diversification.
