Sterling Bank's Transformation: How OneBank Became a Fintech-First Lender
Under CEO Abubakar Suleiman, Sterling Bank has reinvented itself around sector-specific banking verticals and a digital-first culture that has made it an unlikely model for peers.

When Abubakar Suleiman took the helm of Sterling Bank in 2018, he inherited a mid-tier commercial bank chronically stuck in the lower half of the industry's performance league tables — profitable enough to survive but not dynamic enough to grow. Six years later, Sterling has become one of the most talked-about turnaround stories in Nigerian banking, built on a strategy that most of his peers considered too risky: abandoning the catch-all commercial banking model in favour of deep sector specialisation.
The cornerstone of the transformation is what Sterling calls its 'HEART' sectors — Health, Education, Agriculture, Renewable Energy and Transportation. Rather than competing with Tier-1 banks across the full credit spectrum, Sterling has built dedicated teams, risk models and product sets for each vertical. Its agribusiness division has disbursed over ₦80 billion to smallholder farmers through a partnership with the CBN's Anchor Borrowers Programme, while its health finance arm has financed over 400 hospitals and diagnostic centres.
The digital strategy, packaged under the OneBank brand, has been equally ambitious. Sterling's decision to build its core banking platform in-house — using a cloud-native architecture on Microsoft Azure — was controversial in an industry wedded to legacy vendors, but it has paid dividends in deployment speed and cost. New product features that would take competitors 6–9 months to launch are live in Sterling's app within weeks. Its Specta personal loan product, which offers instant credit decisions using psychometric scoring and telco data, has disbursed over ₦300 billion with a non-performing loan ratio below 2%.
The holding company restructuring, completed in 2023, was the logical next step. Sterling Financial Holdings now owns both Sterling Bank and Sterlinnova, a technology arm that licenses its core banking infrastructure to microfinance banks and SACCOs across West Africa. This B2B2C model — the bank as a platform for other financial institutions — is a relatively novel concept in Nigeria and has attracted attention from investors including the International Finance Corporation.
The journey has not been without turbulence. Sterling's capital ratios remain thinner than those of larger peers, and the recapitalisation directive has forced a ₦150 billion equity raise that diluted existing shareholders. But Suleiman's conviction that specialisation beats generalisation in a market as complex as Nigeria's appears, at least for now, to be vindicated by the numbers.
