CNBC's UK Exchange Newsletter: Britain's Jet Fuel Crunch — and How We Got Here

Why It Matters

The reliance on imported jet fuel exposes the UK to geopolitical shocks and price volatility, directly impacting the aviation sector and broader travel‑related economy. Addressing the shortfall is essential for maintaining competitive air travel and national energy resilience.

Key Takeaways

• UK refinery capacity fell 41% from 2000‑2024.
• Only four refineries now meet 85% of demand.
• UK imports 3.1× more kerosene than it produces.
• 60% of kerosene sourced from Gulf states, Strait chokepoint.

Pulse Analysis

The United Kingdom’s refining landscape has contracted dramatically over the past two decades, dropping from 18 facilities in the 1970s to just four today. This decline reflects a mix of low profit margins, limited policy incentives for upgrades, rising carbon costs, and a strategic shift toward electric vehicles. While petrol self‑sufficiency remains, the loss of mid‑size refineries has eroded domestic production of diesel and kerosene, forcing the country to lean heavily on imports for these critical fuels.

Kerosene, the primary component of jet fuel, now arrives largely from the Gulf region, with Saudi Arabia, the UAE and Kuwait supplying about 60% of the UK’s needs. The concentration of supply through the Strait of Hormuz creates a geopolitical bottleneck; any disruption could quickly deplete the nation’s modest one‑month stockpile. European kerosene prices have already doubled, a surge likely to be passed on to consumers via higher airline tickets and could compel carriers to trim routes or capacity during the peak summer travel period. Conversely, higher domestic tourism may offer a modest offset for the hospitality sector.

Policymakers face a choice: reinvest in domestic refining capacity, diversify import sources, or bolster strategic reserves. Incentivising new, low‑carbon refineries could restore a measure of supply security, while expanding storage facilities would cushion short‑term shocks. In the meantime, airlines and regulators must monitor price trends and consider collaborative demand‑management strategies to mitigate the impact on passengers and the broader economy. The jet‑fuel crunch underscores the broader need for resilient energy infrastructure in a post‑pandemic, post‑Ukraine world.
