Yellow plastic barriers are reappearing across petrol forecourts, a visual shorthand for a deepening energy crisis. As the conflict in the Middle East intensifies, the fragility of global fuel supply chains has shifted from a theoretical risk to a tangible reality.

While Allan Leighton, the executive chair of the supermarket chain Asda, dismissed recent supply constraints as merely "temporary shortages" at select forecourts, his admission exposes a systemic vulnerability in global energy logistics. The closure of the Strait of Hormuz—the world’s most critical maritime chokepoint—has paralyzed the movement of oil, triggering a price volatility that is now migrating from the high seas to the local pump. For global markets and net-importing nations like Kenya, this is no longer an isolated commercial issue it is a developing macro-economic shock.

The Anatomy of a Global Chokepoint

The strategic importance of the Strait of Hormuz cannot be overstated. Roughly 20% of the world’s total petroleum consumption passes through this narrow passage daily. Since the US and Israel launched their military campaign against Iran on 28 February, the retaliatory blockade of this waterway has created an immediate, supply-side contraction. When a significant volume of global supply is suddenly severed, the immediate result is not just a price spike, but a logistical scramble. Tankers are rerouted, insurance premiums for maritime shipping in the region have surged, and the just-in-time delivery models that power modern retail are failing.

Allan Leighton’s remarks to the press underscore the immediate impact on retail infrastructure. He noted that while Asda remains committed to maintaining services, "spikiness" in consumer demand—exacerbated by panic buying—often outstrips the ability of logistics networks to replenish stock. This creates the localized, fleeting shortages currently witnessed at specific sites. However, experts in energy logistics argue that these are not merely timing errors. They are symptomatic of a market operating with zero margin for error. When the base supply chain is constricted, retailers lose their buffer, and any slight deviation in demand creates an immediate gap on the forecourt.

The Nairobi Ripple Effect

For a reader in Nairobi, the distance between the Strait of Hormuz and a local petrol station might seem vast, but the economic transmission mechanism is direct and immediate. Kenya is a net importer of refined petroleum products, and the nation's economy is highly sensitive to fluctuations in global oil prices. As global Brent crude prices rally in response to the war, the landed cost of fuel in Mombasa inevitably follows. This triggers a cascading effect that touches every sector of the East African economy.

Economists at the Central Bank of Kenya have long warned that energy price volatility is the primary driver of imported inflation. When the cost of diesel—the lifeblood of Kenyan transport, logistics, and agriculture—surges, the price of goods in Nairobi supermarkets follows within weeks. If the conflict in the Middle East persists, the nation faces a dual threat: an immediate increase in transportation costs and the broader, more insidious threat of a weakened Kenya Shilling (KES) struggling against rising import bills. The global trend is clear: energy insecurity in the North often manifests as a cost-of-living crisis in the South.

The Numbers Behind the Volatility

The data from the last four weeks illustrates a rapid deterioration in market stability. Since the conflict began on 28 February, the escalation in retail fuel costs reflects a fundamental re-pricing of global energy risk. The following data highlights the shifting baseline for consumers and businesses alike:

• Petrol Price Surge: In the UK, average petrol prices have climbed from approximately 132.83p per litre (roughly KES 258) before the war to 150.11p (roughly KES 292) per litre as of late March.
• Diesel Escalation: Diesel prices have seen a sharper increase, reaching an average of 177.68p per litre (roughly KES 346), reflecting the industrial reliance on the fuel and the acute supply constraints for distillates.
• Global Demand Dynamics: Major fuel retailers report that volume demand has spiked by 15-20% in the last fortnight, driven by consumer fears of long-term unavailability rather than genuine consumption increases.
• Supply Chain Buffer: Average reserve stocks at major retail depots have dipped to below 3 days of supply, compared to the industry standard of 7-10 days, leaving little room for logistical disruption.

The Regulatory Tightrope

Governments worldwide are now forced to balance the management of strategic reserves with the necessity of keeping commercial markets fluid. In the UK, the government faces mounting pressure to reduce fuel duties to offset the spike at the pumps. Meanwhile, in East Africa, regulatory bodies like the Energy and Petroleum Regulatory Authority (EPRA) find their mandate complicated by global forces beyond domestic control. Managing retail prices under such conditions requires delicate intervention—subsidies are fiscally unsustainable, yet unchecked price hikes could stifle economic recovery.

The current situation serves as a stark reminder of the fragility of the globalized energy model. As long as the Strait of Hormuz remains contested, volatility will remain the defining feature of the energy market. Retailers may continue to promise that shortages are "temporary" and "addressed very quickly," but for the motorist in Nairobi or the haulage company in London, the instability feels increasingly permanent. The question for policymakers is no longer how to manage the current price spike, but how to insulate their economies from the next inevitable rupture in the global supply chain. History suggests that waiting for the market to correct itself is a strategy that carries significant political and economic risk.
