Prolonged Hormuz Disruption Creates a Growing UK Economic Risk
The disruption surrounding the Strait of Hormuz has emerged as a significant risk to the UK economic outlook. EY’s latest analysis warns that if the strait remains closed through the end of 2026, UK GDP growth could fall to just 0.3% in 2026, compared with its baseline forecast of 0.8%. The modelling also highlights the possibility of a recession if the disruption persists and energy prices remain elevated. (EY)
The warning comes as the Strait of Hormuz remains a critical route for global energy supplies. Recent market developments show how quickly oil prices can respond to changing expectations around the conflict and potential reopening of the waterway. (The Guardian)
Higher Energy Prices Could Keep Inflation Elevated
One of the biggest concerns for the UK economy is the effect of higher energy costs on inflation. EY expects disruption to global energy supplies to push UK inflation above 4% by the end of 2026. Higher household energy and transport costs could reduce disposable income, while businesses face increased production and operating expenses. (EY)
Darren Winters notes that the impact could extend well beyond petrol and household bills. Energy-intensive industries are particularly exposed because higher electricity and fuel costs can weaken margins, reduce competitiveness and discourage new investment.
The Financial Times has warned that “the energy crisis may just be starting”. For investors, this highlights the possibility that an energy shock could continue influencing inflation, interest rates and corporate earnings for longer than initially expected.
Consumers and Businesses Face Increasing Pressure
Higher energy prices can affect the economy through both households and businesses. EY forecasts UK consumer spending growth of only 0.3% in 2026, compared with 0.9% under the pre-conflict outlook. The firm says households have already increased their savings rate and allocated a greater proportion of disposable income towards essential spending. (EY)
Businesses face similar pressures. Higher financing costs, uncertain demand and rising input prices can encourage companies to delay investment and hiring decisions. EY forecasts flat UK business investment growth in 2026 before stronger growth is expected in subsequent years as financing conditions improve. (EY)
The Guardian reported that “UK economy faces recession if strait of Hormuz remains closed, EY warns”. The warning demonstrates how an external energy shock can quickly become a domestic economic problem.
Interest Rates Could Remain Higher for Longer
The energy disruption also creates a difficult challenge for monetary policymakers. Normally, weak economic growth could encourage the Bank of England to reduce interest rates to support demand. However, higher energy prices can simultaneously push inflation upwards, making rate cuts more difficult.
EY expects the Bank Rate to remain at 3.75% throughout 2026 under its baseline scenario, with the next reductions potentially arriving in 2027. If inflation remains elevated for longer, borrowing costs could therefore remain restrictive at a time when households and businesses are already under pressure. (EY)
This combination of weaker growth and persistent inflation creates a challenging environment for investors. Companies exposed to consumer spending, energy costs and high financing requirements may face greater pressure than businesses with stronger balance sheets and pricing power.
Investors Assess Energy Security and Economic Resilience
For investors, the situation reinforces the importance of understanding energy security as an economic and investment theme. The UK remains exposed to global energy prices even when the physical disruption occurs elsewhere. Changes in oil and gas markets can influence inflation, consumer behaviour, corporate margins and monetary policy.
Recent market movements illustrate the uncertainty. Oil prices have repeatedly responded to developments surrounding the potential reopening of the Strait, while investors have adjusted expectations for inflation and interest rates accordingly. (Reuters)
Darren Winters notes, at the same time, the disruption could accelerate investment in alternative energy supplies, grid infrastructure, storage and energy efficiency. This creates potential opportunities alongside the risks, particularly for businesses helping economies reduce their exposure to future energy shocks.
Conclusion
EY’s warning highlights the potentially significant economic consequences if disruption to the Strait of Hormuz continues. Slower GDP growth, higher inflation, weaker consumer spending and delayed business investment could combine to create a challenging environment for the UK economy.
For investors, the situation demonstrates why geopolitical risk and energy security have become increasingly important components of portfolio analysis. Diversification, strong corporate balance sheets and exposure to businesses capable of managing higher costs may become particularly valuable if uncertainty persists.
The outlook remains dependent on developments in the Middle East and the restoration of reliable energy flows. However, the experience of 2026 has already demonstrated how quickly a geopolitical disruption can affect inflation, interest rates, businesses and households across the UK.
