The nigerian petroleum sector is currently experiencing a significant shift, with intense competition between the nigerian national petroleum company limited (nnpc) and dangote refinery and petrochemical limited. This competitive struggle, often described as a price war, is reshaping the dynamics of premium motor spirit (pms) supply, distribution, and pricing within nigeria. Historically, nnpc controlled the importation and distribution of refined petroleum products, but the operational launch of dangote refinery has disrupted this longstanding structure. This paper explores the genesis of the price war, the strategies employed by both entities, the legal and economic implications, and how these developments are influencing pms availability and pricing in nigeria.
