Olaniyi Oladepo: Strengthening financial management in Nigerian banking through regulatory excellence

Taiwo Adeyeye

Nigerian banking has undergone a transformation over the past decade. The 2008-2009 financial crisis exposed weaknesses in risk management, regulatory compliance, and financial reporting that cost the sector billions in non-performing loans and eroded public trust. Rebuilding that trust has required a new generation of finance professionals capable of navigating complex regulatory frameworks while delivering accurate, timely financial information to stakeholders. Among those shaping this evolution is Olaniyi Oladepo, a Banking Officer in Financial Control at Guaranty Trust Bank.

At GTBank, one of Nigeria’s leading financial institutions listed on both the Nigerian and London Stock Exchanges with operations across ten countries, Oladepo leads the regulatory reporting team responsible for daily, mid-monthly, quarterly, and semi-annual submissions to the Central Bank of Nigeria. He also oversees the preparation of audited and unaudited financial statements for the Securities and Exchange Commission, work that determines whether the bank maintains its license to operate and meets its obligations as a publicly traded company.

“Most people think regulatory reporting is just paperwork,” Oladepo says. “But this is how regulators assess whether a bank is safe, whether depositors’ funds are protected, and whether the institution can withstand economic shocks. Every number we submit has implications for the bank’s ability to lend, to expand, to serve customers.”

His responsibilities extend across the full spectrum of financial management. He leads the daily review and analysis of the bank’s trial balance, tracking movements in loan portfolios, deposit balances, short-term instruments, and fixed assets. He prepares monthly management accounts for the Chief Financial Officer and Managing Director, analyzing interest and non-interest income, net interest margins, fee structures, and portfolio optimization strategies.

The management accounts serve as the foundation for executive decision-making. Based on detailed analysis, Oladepo recommended restructuring the bank’s portfolio of short-term liquid assets from Federal government bonds to treasury bills to optimize balance sheet yield. His work with Treasury, Asset and Liability Management, and Business Development teams has supported decisions on currency matching of loans and deposits, maturity profile management, and electronic banking expansion.

“When I present the performance of different business segments like Corporate Banking, Commercial Banking, and Retail Banking, the leadership team sees where value is being created and where resources should be deployed,” Oladepo says. “The reports inform what should happen next.”

Risk management is central to his role. Following the 2008-2009 oil price crash, which triggered a wave of non-performing loans in the downstream oil and gas sector, Oladepo was instrumental in ensuring that all downstream loans and advances carried forward contracts guaranteeing USD delivery against foreign currency obligations. He assesses credit risk through single obligor limits and probability of default analysis for the bank’s top 100 customers. He monitors liquidity ratios daily to ensure regulatory compliance and efficient cash deployment across cash reserves, ATMs, and vaults.

Capital adequacy measurement requires weighting all assets on the bank’s balance sheet in accordance with CBN requirements and Basel II standards. This framework, developed in response to global banking crises, establishes minimum capital requirements that banks must maintain relative to their risk-weighted assets.

“Basel II represents a fundamental approach to ensuring that banks hold sufficient capital to absorb losses,” Oladepo says. “Measuring capital adequacy properly protects depositors, shareholders, and the broader financial system. Doing it poorly creates the conditions for the next crisis.”

His budget and forecasting responsibilities are equally demanding. Oladepo prepares the Annual Board Budget, a process that begins with global, regional, and country economic analysis. He assesses GDP growth projections, oil price forecasts, inflation expectations, and regional political developments against the bank’s strategic objectives. These assumptions underpin deposit and loan growth targets and profitability projections that the board approves and the bank communicates to investors during conference calls and roadshows.

“The budget is a promise to investors,” he says. “When we set targets, we are signaling what we believe we can achieve. Those targets cascade through the organization as KPIs. Every business unit, every profit centre, every cost centre is measured against projections that started with the economic analysis and assumptions I helped develop.”

Beyond routine operations, Oladepo has contributed to significant strategic initiatives. He supported GTBank’s $500 million Eurobond issuance in 2011, developing the sensitivity analysis of the bank’s balance sheet included in the Red Herring prospectus. He attended roadshows with the CFO and Managing Director, providing supporting data in response to investor questions during the capital raise.

He manages the bank’s compliance with restrictive and affirmative covenants under multilateral borrowing programs from the African Development Bank, PROPARCO, the European Central Bank, and the International Monetary Fund. These relationships require continuous monitoring to ensure the bank meets the conditions attached to its international credit facilities.

“Multilateral agencies impose discipline,” Oladepo says. “Their covenants force you to maintain standards that you might otherwise relax. Meeting those covenants consistently builds the credibility that allows you to access international capital markets on favourable terms.”

Product and service costing has been another area of contribution. Through monthly Account Profitability reports measuring returns on every account and product type, Oladepo identified opportunities to reprice commission structures to drive deposit volume growth and improve treasury trading yields. His analysis of ATM usage patterns informed decisions on ATM placement, increasing fee income by directing both GTBank and competitor customers to GTBank platforms.

Strategic planning work with external consultants from KPMG involved assessing the African landscape for growth opportunities. The research concluded that retail banking through electronic platforms, rather than expensive branch networks, was critical to sustainable growth in an environment of thinning margins. The bank has since expanded across Anglophone and Francophone African countries with internet banking and electronic trade platforms supporting international commerce.

Tax planning rounds out his financial management responsibilities. Oladepo supports the preparation, audit, and filing of the bank’s annual Company Income Tax, focusing on tax-exempt income from treasury bills, tax holidays on qualifying loans, capital allowances on fixed assets, and capital gains tax matching on asset disposals. The result is an effective tax rate consistently below the statutory 30%.

“Every naira saved through legitimate tax optimization is a naira available for lending, for investment, for shareholder returns,” he says. “Understanding the tax code and understanding the business are the same discipline.”

His professional credentials reinforce the technical foundation. Oladepo holds membership in the Institute of Chartered Accountants of Nigeria, achieved after completing the Institute’s rigorous professional examinations. The qualification certifies competence in accounting, auditing, taxation, and financial management.

The trajectory from Executive Trainee in 2008 to Banking Officer leading regulatory reporting in 2013 reflects progressive responsibility within GTBank’s Financial Control function. Each role demanded more: broader scope, higher stakes, greater complexity. Each role built capabilities that compound.

“Financial management in banking is about trust,” Oladepo says. “Building that trust requires discipline. Doing the work correctly, consistently, completely. There are no shortcuts.”

As Nigerian banking continues its evolution toward international standards, institutions will increasingly require finance professionals capable of integrating regulatory compliance, risk management, strategic planning, and operational efficiency. Oladepo’s work at GTBank demonstrates what that integration looks like in practice.
