Africa Oil Dependency Deepens After 2025 Supply Shocks

Lead

Africa's reliance on imported refined petroleum products has grown more acute since 2023, producing a material short-term shock to fiscal balances and trade flows as new suppliers and geopolitical relationships reshape intra-continental energy trade. According to Al Jazeera reporting on March 25, 2026, and corroborating shipping-trace data, Iranian refined-product cargoes increased their port calls in West Africa in late 2025 and early 2026 (Al Jazeera, 25 Mar 2026). The International Energy Agency's regional assessments published in 2025 estimate that the continent imported roughly 70% of its refined fuels in 2024, up from approximately 64% in 2019, reflecting underutilized local refining capacity and logistics bottlenecks (IEA, 2025). Major projects such as the Dangote Refinery (commissioned in stages from 2023) changed the structural outlook but have not yet eliminated gasoline and diesel imports for several key markets, leaving countries exposed to volatile spot markets and non-standard bilateral supply arrangements.

This developing pattern—whereby external refiners, including state-linked Iranian entities, have grown more visible in African trade lanes—has tangible macroeconomic consequences. Trade data and national oil company disclosures indicate rising import bills and pressure on foreign-exchange reserves in lower-income petroleum-importing states; the World Bank estimated that fuel import bills for sub-Saharan Africa rose materially in 2024-25, exacerbating external financing gaps (World Bank, 2025). For commodity traders, national oil companies and sovereign balance-sheet managers, the entrance of non-OECD suppliers alters credit and counterparty risk profiles. Institutional investors and sovereign managers must now weigh not just oil-price cyclicality but also refinery utilization, shipping security, and the political economy of supplier diversification when modelling sovereign external vulnerabilities.

The remainder of this note provides a data-driven assessment of the recent flows; a focused deep dive into refinery capacity and utilization; sectoral implications for key producers and importers (notably Nigeria); an appraisal of operational and geopolitical risks; and a contrarian Fazen Capital perspective on sustainable pathways that could reduce the continent's import dependency over a multi-year horizon.

Context

Africa's refining landscape is characterized by a handful of large complexes, widespread small-scale refineries, and significant capacity that is either offline or operating below nameplate. The Dangote Refinery in Nigeria, with a reported capacity of about 650,000 barrels per day (operationally phased since 2023), is the largest single new refinery to come online on the continent in recent years and was marketed as a game-changer for West African fuel self-sufficiency (Dangote Industries, 2023). Despite that capacity, logistical frictions, product slate mismatches (diesel vs naphtha vs gasoline), and domestic distribution gaps meant Nigeria still sourced refined product cargoes internationally in 2024–25. Official Nigerian import statistics and independent trade trackers show gasoline imports continuing at material volumes through 2025, underlining that refinery capacity alone does not immediately eliminate import dependence.

The IEA's 2025 regional report highlighted that constrained capital expenditure on refinery maintenance and upgrades across North and sub-Saharan Africa contributed to aggregate refined-product import dependence of about 70% in 2024 (IEA, 2025). That figure is a year-on-year increase from the late 2010s, when some markets relied less on spot imports due to more reliable local refinery throughput. Comparatively, global refinery utilization averaged well above African averages during the same period—indicating that the issue is more structural than cyclical for the continent and tied to investment, governance and logistics rather than just oil-market cycles.

Geopolitically, the last 18 months of trading have seen increased visibility of non-traditional refined-product suppliers to African ports. Al Jazeera's March 25, 2026 report documents Iranian tanker cargoes that delivered refined products to West African shorelines in late 2025 and early 2026 (Al Jazeera, 25 Mar 2026). Shipping and customs data tracks dozens of product cargoes across the region, a development that signals both commercial opportunity for cash-constrained purchasers and potential policy frictions for governments balancing international sanctions regimes, domestic energy security and diplomatic relationships.

Data Deep Dive

Specific data points clarify the scale and direction of recent shifts. First, the continent's refined-product import dependency: the IEA's 2025 estimates place imports at roughly 70% of consumption in 2024, an increase from roughly 64% in 2019, implying a 6-percentage-point widening over five years (IEA, 2025). Second, refinery capacity concentration: the Dangote Refinery's 650,000 bpd capacity (Dangote, 2023) now accounts for an outsized share of nominal continental nameplate capacity but does not automatically translate into domestic self-sufficiency because of product mix and export commitments. Third, trade patterns: Al Jazeera's reporting and maritime AIS/tanker-tracking analyses indicate dozens of Iranian refinery products shipments to West African ports between Q4 2025 and Q1 2026, a pattern not commonly observed at that cadence before 2024 (Al Jazeera, 25 Mar 2026).

A comparison across markets sharpens the picture. North African countries with integrated refining and petrochemical complexes—Algeria, Egypt, and Morocco—maintained higher internal processing rates in 2024 than sub-Saharan peers, with utilization ratios closer to global benchmarks (IEA, 2025). By contrast, several coastal West and Central African markets exhibited low single-digit refinery utilization in the same period and therefore depended heavily on spot cargoes. Year-on-year import dollar exposure increased: the World Bank's balance-of-payments snapshots for 2024 show fuel imports as a rising share of merchandise import bills in several low-income countries, elevating external vulnerability metrics by multiple percentage points of GDP (World Bank, 2025).

Shipping and logistics add another quantifiable layer: freight and insurance for longer-haul cargoes and open-market purchasing increase landed fuel costs by an estimated $5–$15 per barrel versus intra-regional flows, depending on port and product (industry shipping-cost indices, 2025–26). That delta can erode fiscal savings expected from domestic refining projects that were justified on simpler gross-capacity arithmetic, implying that policymakers should incorporate logistics and product-slate economics into any self-sufficiency calculations.

Sector Implications

For national oil companies (NOCs) and sovereign balance-sheet managers, increased import dependence translates into higher exposure to counterparty credit risk, spot-market volatility and shipping-security premiums. Countries that shift procurement to non-traditional suppliers—whether for price, credit or political reasons—face potential secondary costs related to insurance, sanctions compliance and diplomatic pushback. Nigeria's transition from a major exporter of crude with consistent gasoline imports illustrates this tension: despite hosting the continent's largest single refinery complex, it remains exposed to refined-product imports while domestic distribution and port-handling networks are upgraded.

For private-sector energy firms and traders, these dynamics create both margin opportunities and execution risk. Arbitrage opportunities between Middle Eastern/Asian refineries and African demand centres widened in late 2025 as refinery outages and logistical bottlenecks lifted spot cargo premiums. However, counterparties faced higher credit and operational risks as sovereign and quasi-sovereign purchasers leaned on extended payment terms or supplier financing. Institutional investors evaluating portfolio exposure to African downstream assets should therefore incorporate country-by-country logistics and sovereign-payback scenarios into their valuation models rather than relying purely on nameplate capacity metrics.

For development finance and donor bodies, the policy implication is that capital allocated to downstream capacity without parallel investments in logistics, storage, and governance may deliver suboptimal outcomes. Investments targeted at improving port infrastructure, inland distribution, and regional pipeline interconnectivity can materially reduce landed product costs and thus the need for expensive long-haul imports. See our recent research on energy infrastructure here for a framework to assess where capex delivers the most durable economic benefits.

Risk Assessment

Operational risks remain elevated. Refinery ramp-up schedules frequently slip; maintenance cycles are underfunded; and ancillary infrastructure—terminals, road transport, and retail networks—lags. A single material outage at a major export hub or a protracted logistics disruption can force inland markets back to spot purchasing at elevated premiums. From a financial perspective, sovereigns with low reserves and elevated fuel import bills can experience rapid deterioration in external liquidity; the World Bank noted several countries in 2024–25 where fuel imports accounted for a growing share of foreign-exchange use (World Bank, 2025).

Geopolitical and compliance risks also rose in 2025–26. The increased visibility of Iranian product shipments to West Africa introduces a layer of sanctions and reputational risk for counterparties and insurers, and could invite secondary sanctions or increased scrutiny in international banking relationships. Conversely, diversification away from a narrow set of suppliers can be a rational commercial response by cash-strapped purchasers; the net effect depends on contractual transparency and the degree to which procurement practices are formalized by governments.

Market contagion risks should not be underestimated. If several countries experience concurrent refinery outages or if short-term supply squeezes push diesel premiums substantially higher, there can be cascading impacts on broader economic activity—transport, agriculture, and industry—all of which can amplify fiscal stress. For portfolio risk modelling, scenario tests that include simultaneous logistic, refinery and balance-of-payments shocks produce materially worse outcomes than single-factor stress tests; that is an input we recommend institutional investors integrate into sovereign credit assessments.

Fazen Capital Perspective

Our contrarian view is that headline refinery capacity figures—while important—have been over-emphasized by market participants and some policymakers as a proxy for near-term energy independence. The Dangote Refinery's 650,000 bpd nameplate capacity is an essential long-term asset, but capacity alone does not equal immediate supply security. The missing link is the midstream ecosystem: terminals, inland distribution, stable offtake contracts, and creditworthy purchasers. Absent coordinated investments and clear offtake legal frameworks, large refineries risk becoming export-oriented cash-flow engines rather than domestic security assets.

We also believe there is an underappreciated opportunity in regional integration. Markets that pursue cross-border pipeline projects, regional storage hubs and harmonized regulatory regimes can reduce their collective import dependency faster and at lower cost than countries acting alone. From a capital-allocation standpoint, development finance institutions and private investors should prioritise projects that demonstrably reduce landed fuel-cost deltas—such as coastal hub storage or feeder pipelines—over incremental increases in isolated processing capacity. Our prior work on infrastructure prioritization is available here.

Finally, we note that increased procurement from non-traditional suppliers (including Iran in late 2025) reflects commercial realities for purchasers facing cash and credit constraints. A realistic policy response combines short-term acceptance of diversified sourcing with medium-term investments in governance, logistics, and regional cooperation. For investors, the implication is to stress-test cashflows under alternative procurement regimes and to price in higher political and compliance premiums where counterparties lack transparent payment mechanisms.

FAQ

Q: How quickly could Africa materially reduce its refined-product import dependence? A: Reduction is unlikely to be rapid. Even with new refineries online, historical evidence suggests that measurable import-dependence declines require multi-year improvements in midstream logistics and distribution. A plausible multi-country pathway to reduce dependence by 10–15 percentage points would likely take 3–5 years, conditional on sustained capex, regulatory reform, and stable financing for storage and transport projects.

Q: Does sourcing petrol from Iran present legal risks for African buyers? A: It can. While not every shipment triggers sanctions, purchasing from entities linked to sanctioned regimes increases banking and insurance friction, raises freight and insurance costs, and can complicate access to Western capital markets. Buyers often accept those costs for short-term liquidity relief, but institutional counterparties and insurers will escalate due diligence and pricing for such trade lines.

Bottom Line

Africa's import dependency for refined fuels rose into 2024–25 and has been accentuated by new supplier patterns and persistent midstream gaps; addressing the problem requires coordinated investments across refining, storage and logistics rather than reliance on nameplate refining capacity alone. Policymakers and investors should shift focus from headline capacity to the economic costs of landed products when assessing energy security and sovereign vulnerability.
