OPEC+ Output Increases Offer Little Relief as Hormuz Closure Reshapes West African Fuel Import Costs
An OPEC+ decision to raise production quotas by 188,000 barrels per day from July has done little to ease oil prices trading near US$93 per barrel, as the continued closure of the Strait of Hormuz keeps global supply constrained and fuel import costs elevated across West Africa, where most economies remain structurally dependent on refined petroleum product imports.
The Hormuz Bottleneck and Its Structural Impact on West African Energy Security
The Strait of Hormuz, through which roughly 20% of global oil trade flows, has been closed since late February following US and Israeli military strikes on Iran. Brent crude, which traded near US$72 per barrel before the conflict began, has since surged to US$93, representing a near 30% price shock that has rippled through import-dependent economies from Dakar to Lagos.
For West African nations, the consequences are not abstract. Ghana, Senegal, Côte d’Ivoire, and Nigeria each maintain fuel subsidy regimes or price stabilisation mechanisms that translate crude price volatility directly into fiscal pressure. The Bank of Ghana and the Central Bank of Nigeria have both flagged imported inflation as a primary risk to monetary stability in 2025, with fuel costs feeding into transport, food distribution, and manufacturing input prices.
Nigeria, as OPEC’s sole West African member and the continent’s largest crude producer, occupies a structurally ambiguous position: it benefits from higher export revenues while simultaneously struggling to supply its own refineries with affordable feedstock, given the Dangote Refinery’s ongoing ramp-up and persistent infrastructure gaps in the Niger Delta.
OPEC+’s Institutional Credibility Under Strain
Sunday’s quarterly online meeting of OPEC+ ministers produced a quota increase of 188,000 barrels per day for July, matching the June adjustment and continuing a pattern of incremental hikes that began in April. Seven core members, Saudi Arabia, Russia, Iraq, Kuwait, Kazakhstan, Algeria, and Oman, hold the actual spare capacity to execute these increases. The remaining 14 member states are largely producing at or near their limits.
“An OPEC+ production increase means very little while the Strait of Hormuz remains closed,” said Jorge Leon, analyst at Rystad Energy and a former OPEC official. “When the Strait of Hormuz reopens, the market could move very quickly from fear of shortage to fear of surplus.”
The cartel’s credibility has been further weakened by the United Arab Emirates’ decision to withdraw from OPEC after nearly 60 years of membership. The UAE, the world’s seventh-largest oil producer, cited a structural mismatch between its expanding production capacity and the quotas it was permitted to pump under the OPEC+ framework. Abu Dhabi has made clear its intention to maximise output independently.
“They don’t want to be dictated to, they want to maximise their revenues,” said Lawrence Haar, a lecturer in finance at the University of Brighton. The UAE’s exit has removed a significant bloc of excess capacity from the cartel’s negotiating leverage, and analysts warn that Iraq’s potential departure could be more destabilising still. “If Iraq were to leave, it could mark the end of OPEC+,” Haar added.
Saudi Arabia, the cartel’s dominant member, is expected to offer more flexible quota arrangements to prevent further defections. However, with Gulf production shut-ins having already collapsed the group’s actual output from 42.77 million barrels per day in February to 33.19 million bpd in April, according to OPEC’s own figures, the compensation and penalty framework has become largely inoperative.
South Africa’s Fuel Price Mechanism Illustrates Broader Fiscal Exposure
The most granular illustration of the Hormuz shock’s downstream effects comes from South Africa, where the Central Energy Fund’s latest data points to potential pump price decreases of R2.70 per litre for petrol and R2.50 for diesel. However, the final phase-out of Treasury’s fuel tax relief measures, first introduced in April, will add R1.50 per litre back into the price equation, leaving net consumer relief closer to R1 per litre.
While South Africa sits outside the ECOWAS zone, its pricing mechanism is instructive for the region. Ghana’s National Petroleum Authority operates a similar automatic adjustment formula, as does Senegal’s downstream regulator. In both cases, governments face a structural tension between fiscal consolidation requirements, including those tied to IMF programme conditionalities in Ghana’s case, and the political cost of passing through global oil price shocks to consumers.
Ghana’s fuel subsidy bill has been a recurring source of fiscal slippage, contributing to the debt distress that triggered its 2023 IMF programme. With the cedi having depreciated approximately 15% against the US dollar over the past 12 months, the local-currency cost of crude imports compounds the dollar-denominated price shock, squeezing both the fiscal position and household purchasing power simultaneously.
Regional Energy Policy and the AfCFTA Dimension
The Hormuz crisis has renewed debate about West Africa’s structural dependence on refined product imports, despite the region’s substantial crude production capacity. Nigeria, Ghana, and Senegal all produce oil, yet refining capacity remains insufficient to meet domestic demand. The Dangote Refinery in Lagos, with a nameplate capacity of 650,000 barrels per day, represents the most significant attempt to address this gap, but its full commissioning remains pending and its output has not yet materially altered regional supply dynamics.
Under the African Continental Free Trade Area framework, energy trade is categorised as a strategic sector. The AfCFTA Secretariat has identified downstream petroleum infrastructure and cross-border energy trade as priority areas for regulatory harmonisation. A more integrated West African refining and distribution network, connected to ECOWAS trade corridors, would reduce the region’s exposure to external supply shocks of precisely the type the Hormuz closure represents.
WAEMU member states, which share the CFA franc and a common external tariff, have a particular institutional incentive to coordinate fuel pricing policy. Divergent national fuel subsidies create arbitrage opportunities and informal cross-border fuel trade that undermines both fiscal frameworks and official trade statistics. A common WAEMU fuel pricing protocol, aligned with the ECOWAS Energy Protocol, remains an unfinished item on the regional integration agenda.
Policy Pathways: From Price Management to Structural Reform
US President Donald Trump stated on Thursday that, in a worst-case scenario, the Strait of Hormuz could remain closed until September, though he expressed confidence that negotiations with Iran would conclude before Labour Day on 7 September. Oil industry experts caution that even an immediate reopening would leave supply disruptions in place through the end of 2025, as tanker scheduling, insurance markets, and Gulf export infrastructure require time to normalise.
OPEC+ ministers are scheduled to reconvene on 5 July. Markets will be watching whether Saudi Arabia moves to offer more substantive output flexibility, and whether renewed US-Iran diplomacy shifts the geopolitical calculus sufficiently to bring Brent crude back toward the US$72 range that prevailed before the conflict.
For West African finance ministries and central banks, the immediate policy question is not whether global oil prices will fall, but how to manage fiscal and monetary exposure in the interim. Ghana’s Ministry of Finance, operating under IMF programme constraints, has limited room to extend fuel tax relief without triggering programme review. Nigeria’s Federal Executive Council faces analogous pressure, with the post-subsidy fuel pricing regime introduced under President Tinubu still politically contested.
The deeper structural answer lies in accelerating refining capacity, harmonising regional energy trade rules under AfCFTA and ECOWAS frameworks, and building strategic petroleum reserves that can buffer short-term supply shocks. These are not new recommendations. The Hormuz closure has simply made the cost of inaction, measured in cedis, naira, and CFA francs per litre, impossible to ignore.
