The Refinery War and the Rule of Law: Competition, Monopoly, and the Soul of Nigeria's Downstream Petroleum Market.

The Refinery War and the Rule of Law:

Competition, Monopoly, and the Soul of Nigeria's Downstream Petroleum Market

“Taken as a whole, the legislative history illuminates congressional desire to edit a statute that would code for the protection of competition, not competitors.”

– Chief Justice Earl Warren, in Brown Shoe Co. v. United States, 370 U.S. 294 (1964)

1.Introduction: A Dispute That is Larger Than It Appears

In May 2026, the Federal High Court in Lagos became the arena for a contest that Nigerian lawyers, economists, and policymakers have long known was inevitable. Dangote Petroleum Refinery, the $20 billion, 650,000-barrel-per-day colossus that represents the single largest private industrial investment in sub-Saharan African history, filed a suit challenging the validity of fuel import licences issued and renewed by the Nigerian Midstream and Downstream Petroleum Regulatory Authority (NMDPRA) to the Nigerian National Petroleum Company Limited (NNPCL) and a cohort of independent marketers, including NIPCO, AA Rano, Matrix Energy, Shafa Energy, Pinnacle Oil and Gas, and Bono Energy.

Dangote Refinery’s central argument is that the continued issuance of these licences, at a time when domestic production meets the preponderance of Nigeria’s daily petrol needs, violates the letter and spirit of the Petroleum Industry Act, 2021 (PIA). NNPCL’s counter is equally forceful: that granting Dangote’s prayers would hand a single private entity monopoly control of Nigeria’s fuel supply, expose consumers to price exploitation, and threaten national energy security.

Both arguments have force. Neither, standing alone, is sufficient. And that, precisely, is why this dispute demands a rigorous competition law analysis, not merely a commercial or political one.

This article argues that the real issue before the courts, the regulators, and the nation is not whether Dangote is right or NNPCL is right, but whether Nigeria has the legal and institutional architecture to prevent any actor, state or private, from acquiring and abusing market dominance in the downstream petroleum sector. The answer, properly read, is yes. But that architecture is being stress-tested as never before, and its survival depends on the willingness of regulators and courts to apply it without fear or favour.

2.The Statutory Framework: What the Law Actually Says

2.1 The Petroleum Industry Act, 2021

The PIA, signed into law in August 2021 after nearly two decades of legislative gestation, represents the most comprehensive overhaul of Nigeria’s petroleum legal architecture since independence. For present purposes, three sets of provisions are critical.

First, Section 317 of the PIA establishes a clear preference for domestically refined petroleum products. The Act empowers the NMDPRA, the midstream and downstream regulator created by the PIA to replace the defunct Department of Petroleum Resources, to regulate import licences for petroleum products. Crucially, the Act contemplates that import authorisations should be assessed against the sufficiency of domestic supply, emphasising that imports should be permitted only where domestic production is demonstrably inadequate. This is not merely a commercial preference; it is a statutory policy directive that reflects a deliberate legislative choice to build Nigeria’s refining capacity as a matter of industrial and energy sovereignty.

Second, Section 109 of the PIA establishes the Domestic Crude Oil Supply Obligation (DCSO) framework, which mandates upstream producers and lessees to dedicate a portion of their crude oil production to the domestic market at willing-buyer, willing-seller pricing. The DCSO is the PIA’s principal mechanism for ensuring that domestic refineries are not starved of feedstock while Nigeria exports crude for overseas refining and reimports it at a higher cost. The repeated failures of NNPCL and the NUPRC to fully enforce this obligation in Q1 2026, a period during which Dangote Refinery operated below capacity due to inadequate crude supply, is a matter of public record and regulatory embarrassment.

Third, and most relevant for competition law practitioners, Sections 167 and 202 - 203 of the PIA vest in the NMDPRA the explicit authority to regulate anti-competitive behaviour in the midstream and downstream sectors. Section 202, in particular, empowers the Authority to regulate prices and impose access obligations where it determines that a licensed activity constitutes a monopoly service, that there is insufficient competition in the relevant market, or that a licensee is a dominant provider. These are not ornamental provisions. They are the downstream petroleum sector’s primary competition law tools, and they have yet to be deployed with anything approaching their full statutory potential.

2.2 The Federal Competition and Consumer Protection Act, 2018

The Federal Competition and Consumer Protection Act (FCCPA), 2018, which established the Federal Competition and Consumer Protection Commission (FCCPC) as Nigeria’s principal competition authority, applies to all sectors of the Nigerian economy, including the petroleum sector, except where a specific sectoral law expressly excludes it.

The petroleum sector is not excluded from the reach of the FCCPA. On the contrary, the FCCPA fills the gaps left by the PIA and other sectoral legislation. Sections 70 to 73 of the FCCPA, Part VI of the Act, contain Nigeria’s most elaborate statutory treatment of dominant market position, which Dangote occupies. Section 72 prohibits the abuse of a dominant position and empowers FCCPC to declare a dominant position as abusive where its activities “have the effect of unreasonably lessening competition in a market” and specifically enumerates abusive practices, including: refusing to supply goods or services to competitors; engaging in predatory pricing; applying dissimilar conditions to equivalent transactions; and imposing terms that create barriers to market entry or expansion.

The FCCPA does not prohibit dominance. It prohibits the abuse of dominance. This distinction is not merely technical: it reflects the liberal economic philosophy embedded in the Act, which holds that market success achieved through efficiency, investment, and innovation ought to be rewarded, while market power deployed to foreclose competition, distort prices, or harm consumers must be restrained.

In the context of this dispute, both dimensions of the FCCPA’s dominance framework are engaged. The question is not only whether Dangote Refinery, by virtue of its scale and the PIA’s supply hierarchy provisions, might acquire a dominant position in the downstream petroleum market, but also whether NNPCL, as a state entity with preferential access to crude, institutional relationships with regulators, and a history of subsidised importation, has itself been the principal architect of anti-competitive distortions in the Nigerian downstream sector for decades and thus liable to abuse its position.

3.The Paradox at the Heart of the Dispute

It is noteworthy that NNPCL has raised concerns about monopoly in this litigation. Historically, NNPCL has played a significant role in Nigeria’s downstream petroleum market. For many years, NNPCL effectively controlled petrol importation through the defunct Pipeline and Product Marketing Company (PPMC) and the Petroleum Products Marketing Company (PPMC). The deregulation of the downstream sector, formalised by the PIA, was a legislative response aimed at addressing distortions, rent-seeking, and supply challenges caused by the previous state monopoly.

Now, NNPCL’s caution regarding monopoly, while simultaneously defending the continuation of import licenses, many of which were granted when domestic supply met up to 80% of daily demand, warrants careful examination of the legal arguments presented.

This is not to say that Dangote Refinery is without fault or does not pose a legitimate competitive concern. A 650,000-barrel-per-day refinery producing in a market where total daily consumption is approximately 51 million litres will, by sheer arithmetic, command a structural dominance that raises genuine competition questions. The concern is not hypothetical. At near-full capacity, Dangote Refinery can supply Nigeria’s entire petrol demand with room to spare. In a market where supply is so concentrated in a single private actor, the FCCPA’s abuse of dominance provisions become, if anything, more, not less, important.

But structural dominance arising from lawful investment, statutory encouragement, and genuine productive capacity is not, in itself, an abuse. What would constitute an abuse, and what the FCCPC should be vigilant to detect and sanction, is any conduct by Dangote Refinery that, having achieved market dominance, exploits it through pricing practices that have no efficiency justification, refuses to supply downstream distributors on commercially reasonable terms, or engages in exclusionary conduct designed to foreclose the entry of future domestic competitors, including the moribund Port Harcourt, Warri, and Kaduna refineries that the Nigerian government has pledged to rehabilitate.

The competition law framework demands a nuanced response: welcome the investment, protect the local production policy, but refuse to immunise any actor, private or state, from the disciplines of the law.

4.The Core Competition Law Question: Who Controls the Market and How?

The fundamental competition law question in this dispute has three dimensions.

The first is whether the continued issuance of import licences in circumstances of demonstrable domestic sufficiency is an unlawful state measure that distorts competition? This is Dangote’s primary legal argument, and it is stronger than its critics admit. Competition law, both in its FCCPA expression and in its analogues in more developed jurisdictions, recognises that state regulatory measures can constitute anti-competitive instruments when deployed, whether by design or effect, to advantage certain market participants over others without legitimate policy justification. The NMDPRA’s grant of import licences covering 600,000 to 720,000 metric tonnes of Premium Motor Spirit at a time when domestic production was supplying roughly 80% of daily consumption is not, on its face, a measure justified by supply insufficiency. If the PIA’s import framework is to be given any meaning, the NMDPRA bears the burden of demonstrating that the licences were issued on evidence-based grounds, not as a default continuation of a pre-deregulation import culture.

The second dimension is whether Dangote Refinery’s market position constitutes dominance under the FCCPA, and if so, what conduct obligations flow from that dominance? On available data, there is a strong argument that Dangote Refinery is, or is rapidly approaching, a dominant undertaking in the Nigerian downstream petroleum market within the meaning of Section 67 of the FCCPA. The FCCPC is empowered, and arguably obligated, to assess this question formally and to issue guidance or binding directions on the pricing and supply conduct obligations that flow from dominance. The refinery’s IPO plans, which will make its market conduct and pricing policies subject to public investor scrutiny, make this regulatory clarity even more urgent.

Thirdly, what is NNPCL’s market position, and does its conduct in this litigation reveal a strategic intent to preserve import-dependent market arrangements that favour its own commercial interests? This is the question that nobody in the current debate is asking loudly enough. NNPCL is not a passive regulator. It is a commercial entity with its own import licences, its own trading arm, its own price-setting influence, and, critically, a structural relationship with the federal government that gives it access to crude oil allocation decisions, regulatory relationships, and policy influence that no private competitor can match. If NNPCL is using this litigation to preserve an import-centric market architecture in which its own commercial position is stronger than it would be in a genuinely competitive domestic refining market, that conduct itself warrants FCCPC scrutiny under the abuse of dominance provisions of the FCCPA.

5.The Institutional Architecture: Is it Fit for Purpose?

The PIA bifurcated the petroleum sector’s regulatory structure. The NUPRC regulates upstream operations, whilst the NMDPRA regulates midstream and downstream. Both are empowered by the PIA to address anti-competitive conduct within their respective domains. The FCCPC, by virtue of the FCCPA, provides horizontal oversight across all sectors.

In theory, this framework is robust. In practice, there are at least three institutional gaps that this dispute has exposed.

The first gap is regulatory capture risk. The NMDPRA is the regulator that issued the contested import licences. It is also a defendant in the Dangote suit. The conflict of interest this creates, between the NMDPRA’s role as a licensor of imported products and its role as a guardian of the PIA’s domestic production preference, is serious. A regulator cannot credibly adjudicate the legality of its own acts. The courts are right to assume jurisdiction, but the deeper institutional answer is a structural firewall between the NMDPRA’s licensing and adjudicatory functions.

The second gap is inter-agency coordination. The PIA requires coordination between the NUPRC and the NMDPRA on domestic crude supply data. The FCCPA requires the FCCPC to be consulted on competition matters in regulated sectors. In practice, neither coordination mechanism has functioned as Parliament intended. It is not known if the FCCPC has, to date, issued any formal market analysis or guidance on the competitive structure of the downstream petroleum market post-PIA. This is a gap that undermines the credibility of all parties’ competition arguments in the current litigation: there is no baseline market definition, no formal dominance determination, and no regulatory benchmarking of the prices at issue.

The third gap is enforcement consistency. The DCSO framework under Section 109 of the PIA has been chronically under-enforced. If upstream producers can fail to meet their domestic crude supply obligations without regulatory consequence, the downstream refining investment that the PIA was designed to incentivise will remain vulnerable to exactly the supply disruptions that Dangote has publicly complained of. Enforcement of the DCSO is not merely an upstream regulatory question: it is a prerequisite for a competitive downstream market.

6.Controlling Monopoly: A Framework for the Way Forward

It is stressed that this article does not argue the insulation of any of the dominant players – NNPC or Dangote Refinery - from competition. Nor does it argue that import licences should be abolished as a matter of course. What it argues is that the prevention and control of monopoly, in any form, whether private or state-backed, must be the guiding principle of Nigerian petroleum sector regulation.

The following framework is proposed:

The FCCPC should initiate a formal market inquiry into the Nigerian downstream petroleum sector under Section 76 of the FCCPA. Such an inquiry would establish a rigorous, evidence-based understanding of market concentration, dominance, and competitive dynamics in the post-PIA environment. Its findings would provide a principled basis for regulatory decisions on import licences, pricing regulation, and access obligations.

The NMDPRA should publish transparent, data-driven criteria for the issuance of import licences under the PIA. These criteria should be anchored in domestic supply sufficiency data, not institutional preference or commercial lobbying. The NMDPRA’s current discretion is not unlimited: the PIA’s domestic production preference imposes a purposive constraint that the regulator must honour.

The FCCPC should issue formal guidance on the competition obligations of dominant undertakings in the downstream petroleum sector. This guidance should address pricing conduct, supply terms, access to infrastructure, and the treatment of downstream distributors. It should apply equally to private actors and to state-owned or state-affiliated entities.

The DCSO framework must be enforced without exception. The commercial logic of the PIA’s domestic refining preference is only as strong as the crude supply that underwrites it. NUPRC must treat DCSO non-compliance as the serious regulatory breach it is, not as a commercial inconvenience to be negotiated around.

The Federal High Court, in adjudicating the Dangote suit, should resist the temptation to resolve a competition policy dispute through a purely administrative law lens. The validity of the import licences is a question of statutory interpretation, but the wider framework within which that question must be answered is one of competition law and industrial policy. An amicus brief from the FCCPC on the competition dimensions of the case would be both appropriate and valuable.

7.Conclusion: The Law Must Lead

The Dangote-NNPCL-marketers dispute is, at its core, a competition law crisis masquerading as a licensing dispute. It forces Nigeria to confront questions it has deferred for too long: What does a genuinely competitive downstream petroleum market look like? What is the boundary between industrial policy and anti-competitive state action? What obligations flow from market dominance, whether it is the dominance of a private refinery or the structural dominance of a state-owned corporation?

The PIA and the FCCPA, read together, provide a framework equal to these questions. The PIA’s domestic production preference is not a licence for private monopoly; it is a policy instrument for industrial development that must be disciplined by competition law safeguards. The FCCPA’s abuse of dominance provisions are not reserved for obvious market abusers; they are tools for the ongoing, evidence-based management of market power in sectors of critical national importance.

Nigeria has spent decades suffering the consequences of monopoly in its petroleum sector, first the state monopoly of NNPCL and its predecessors, which produced endemic scarcity, corruption, and import dependence; and now the looming possibility of a private monopoly that, however economically productive it may be, cannot be allowed to exist beyond the reach of competition law.

The law must lead. The courts must interpret the PIA and the FCCPA purposively, giving full effect to their competition mandates. The FCCPC must assert its horizontal jurisdiction without deference to the commercial or political weight of the parties. The NMDPRA must exercise its licensing discretion on the basis of transparent, evidence-based criteria. And all parties, Dangote, NNPCL, the independent marketers, and the federal government, must accept that in a nation governed by law, no investment, however large, and no institution, however powerful, is above the competition rules that protect Nigerian consumers and the integrity of the Nigerian market.

The refinery war will ultimately be decided in court. But the competition law framework will determine what kind of petroleum market Nigeria builds after the verdict. That is the longer game, and it is the one that matters most.
