The Gulf Oil Shock: How Strait of Hormuz Risk Reaches Nigerian P&Ls

The Strait of Hormuz disruption since 28 February has lifted Brent into the $90s. For Nigeria the shock is fiscally positive but operationally negative — fuel, transport and food costs pass through to corporate P&Ls within weeks.

It is counter-intuitive: Nigeria exports crude, so a higher oil price should be a windfall. In the short run, the opposite is true for the real economy. The Gulf shock of early 2026 is a clean case study — a geopolitical flare-up sent Brent above $120 in March, and the consequences reached Nigerian businesses through three sequential channels.

**Channel 1 — Fuel.** Higher crude prices feed into refined-product costs. Even with Dangote operational, pump and diesel prices rose within weeks.

**Channel 2 — Transport and logistics.** Fuel is a direct input into moving goods and people. Freight, distribution and commuting costs followed within weeks.

**Channel 3 — Food.** Because food in Nigeria is moved by road over long distances, a fuel shock becomes a food shock with a short lag — which is precisely why food inflation climbed back toward 16%.

Why doesn't the export windfall offset this? Timing and allocation. Cost pass-through hits within weeks; incremental oil revenue arrives over quarters and is partly pre-committed to debt service. For most non-oil firms, the net effect is negative.

**Business implications.** Map your fuel-intensity per litre and per tonne-km. Pre-decide the diesel/PMS trigger at which you adjust pricing. Treat the refinery as a buffer, not a shield.

**Outliers view.** The Strait of Hormuz is 6,000 km from Lagos but on every CFO's cost line.
