Fitch Ratings warns that Nigeria’s banks are increasingly vulnerable to physical and transition climate risks, threatening balance sheets and prompting a reassessment of lending strategies amid sectoral and policy shifts.
Nigeria’s banks are confronting a slow-building credit threat from climate change that could weaken balance sheets, lift loan impairments and force a rethink of where lenders place their money, according to Fitch Ratings.
The agency said in a report on African banks that the immediate hit from climate change is still limited, but the pressure is likely to rise as governments tighten emissions policies and extreme weather becomes more severe. For Nigeria, the warning is especially sharp because banks remain heavily tied to oil and gas, agriculture and other sectors that are vulnerable both to the global energy transition and to physical disruption.
Fitch said Nigerian lenders are unusually exposed to borrowers in industries that could lose value as cleaner technologies spread, carbon rules become stricter and investors continue shifting away from high-emitting assets. That raises the risk that some loans could sour if businesses built around fossil fuels or carbon-intensive production become less profitable.
The agency also pointed to agriculture as a major concern. Floods, droughts and erratic rainfall can reduce output, weaken farmers’ repayment capacity and reduce the worth of land and other assets used as collateral. Nigeria’s climate risk profile is already severe: the country’s Department of Climate Change says it faces rising temperatures, irregular rainfall, drought in the north and damaging floods and coastal erosion in the south, while the ND-GAIN Index ranked it 160th out of 181 countries in 2020.
Fitch projected that Nigeria could score between 50 and 55 on its Climate Vulnerability Signals framework by 2050, placing it among the continent’s more exposed economies alongside Ghana, Egypt, Kenya and South Africa. The report said Nigeria is also developing carbon-pricing and carbon-market rules as part of its Paris Agreement commitments, a step that could reshape the financing environment further.
The warning fits a wider pattern across Africa. Fitch said the region’s banks are structurally exposed to climate risk, with transition pressures likely to dominate in the near term and physical threats becoming more important over time. Separately, Moody’s has estimated that nearly a quarter of African bank lending is tied to companies facing carbon transition risk, underlining how deeply the continent’s lenders remain linked to mining, oil and gas, manufacturing and transport.
For Nigerian banks, that means climate change is no longer just an environmental issue. It is becoming a mainstream credit risk, one that may influence lending, pricing, provisioning and portfolio strategy for years to come.

- https://www.myjoyonline.com/african-banks-face-structural-exposure-to-climate-risk-credit-implications-evolving/ – Fitch Ratings has highlighted that African banks are increasingly exposed to climate-related credit vulnerabilities, primarily due to transition risks in the near term and physical risks in the longer term. The report, titled ‘African Banks Have Structural Exposure to Climate Risk; Credit Implications Evolving’, indicates that while the immediate impact remains manageable, both transition and physical climate risks are expected to intensify over the coming decades, posing significant challenges for banking systems across the continent. The report emphasizes the need for banks to strengthen risk frameworks, diversify portfolios, and adapt funding structures to mitigate these evolving risks.
- https://african.business/2023/03/finance-services/moodys-african-banks-exposed-to-billions-in-carbon-risks – A Moody’s survey reveals that nearly a quarter of African banks’ lending is directed towards companies facing carbon transition risks, amounting to approximately $106 billion, or about 22% of their loan books. This exposure is predominantly in sectors such as mining, oil & gas, and manufacturing & transport. The report underscores that African banks are more exposed to governance and environmental risks than their global peers, with relative governance weaknesses leading to operational and loan losses. The findings highlight the need for African banks to enhance their risk management practices to address these environmental challenges.
- https://climatechange.environment.gov.ng/climate-risks – Nigeria’s Department of Climate Change provides an overview of the country’s climate risk landscape, highlighting key hazards such as rising temperatures, erratic rainfall patterns, severe droughts, desertification in the northern regions, and devastating floods and coastal erosion in the south. The 2020 ND-GAIN Index ranks Nigeria 160 out of 181 countries, indicating a high level of vulnerability to climate change. The department emphasizes the need for comprehensive climate risk assessments and adaptation strategies to build resilience against these challenges.
- https://africanmarkets.com/en/news/africa/fitch-downgrades-afreximbank-to-bbb-outlook-negative – Fitch Ratings has downgraded the African Export-Import Bank’s (Afreximbank) Long-Term Issuer Default Rating (IDR) to ‘BBB-‘ from ‘BBB’, with a Negative Outlook. The downgrade reflects higher solvency risk, stemming from an increase in the bank’s non-performing loans (NPLs) ratio, which exceeded the 6% ‘high risk’ threshold at the end of 2024. The revision of risk management to ‘weak’ is due to low transparency in the recent reporting of loan performance relative to multilateral development bank peers. This development underscores the challenges faced by African banks in managing credit risks, particularly in the context of evolving environmental and economic conditions.
- https://www.afdb.org/en/news-and-events/press-releases/fitch-affirms-triple-rating-african-development-bank-outlook-stable-44746 – Fitch Ratings has affirmed the African Development Bank’s credit rating at ‘AAA’, with a stable outlook. The affirmation reflects the ‘extraordinary support’ of the Bank’s shareholders and its strong capitalization and risk management capabilities. Fitch views the Bank’s risk-management policies as ‘conservative’ and assesses them as ‘excellent’, in line with AAA-rated peers. The affirmation also speaks to the importance of the Bank’s public policy mandate, particularly during challenging times, highlighting the resilience and stability of the African Development Bank in the face of evolving global economic conditions.
- https://www.myjoyonline.com/african-banks-to-remain-exposed-to-domestic-global-operating-environments-risks-fitch/ – Fitch Ratings has disclosed in its African Banks Outlook 2025 report that African banks will remain exposed to domestic and global operating environment risks in 2025. While most countries are showing a good degree of resilience, a fall in commodity prices cannot be ruled out. The report also notes that asset quality risks will remain prominent, with households and businesses continuing to be hit by high inflation and interest rates. However, a small reduction in impaired loans ratios is anticipated due to loan growth, declining interest rates, and lower inflation. The report emphasizes the need for banks to address these risks through strong pre-impairment profits, satisfactory loan growth, solid non-interest income, and strong operating efficiency.
