How the Iran war could change energy markets in Oil & Companies News 08/04/2026 The inherent risk to economies relying on oil and LNG shipped from the Gulf has been laid bare. Could supply disruption and the high prices triggered by the war be the last straw for countries that depend heavily on hydrocarbon imports? In a recently published new scenario, our Energy Transition experts – Prakash Sharma, Jom Madan and Lindsey Entwistle – consider what happens if the war in Iran proves to be the catalyst for hydrocarbon-importing countries to push hard for energy independence. I asked them about the implications, including for oil and gas demand. What problem has the war exposed? The vulnerability of economies with energy systems that are heavily dependent on imported oil and gas. The Iran war comes not long after the economic turmoil caused by the Russia-Ukraine war. Both conflicts politicised oil and gas supply, inflicted supply insecurity, high prices and extreme price volatility. The Strait of Hormuz blockade, which began five weeks ago, halted 15% to 20% of global oil and LNG flows and pushed Brent crude above US$100 per barrel while LNG spot prices have doubled. These wholesale prices flow rapidly through the economy to consumers at the pump, into their gas and electricity bills, and indirectly to a wide range of food products, goods and services. Import-dependent countries are hit disproportionately. What measures are governments taking? So far, a few particularly exposed import-dependent Asian countries have taken emergency demand-side measures: mandatory work-from-home and fuel rationing, industrial users facing curtailment orders with essential sectors prioritised. This is the thin end of the wedge. In the next two to three months, shortages will ripple out through Asia and into Europe and even the US. Europe and Asia will become increasingly reliant upon their strategic reserves to sustain supplies of oil and refined products. In the power sector, most countries have alternatives to keep the lights on – more coal-fired generation and nuclear plants running harder. But these measures are minor adjustments to the immediate crisis and can only be a temporary fix. Is there a sustainable solution? If countries are prepared to use the crisis to push harder towards energy independence, then the obvious answer is aggressive electrification. Achieving energy independence, though, requires governments to bite the bullet. They would have to enact policy to accelerate the shift to an economy powered by electrons and away from the current dependence on imported oil and gas molecules. Even if governments were to commit to such a strategy, change on the ground can’t happen overnight. In our integrated modelling analysis, change starts to take hold only after 2030: electrification accelerates, coal retirements are deferred and renewables expand. After 2040, nuclear power and supporting supply chains rapidly scale. Road transport power demand surges 57% as EVs achieve a dominant market share and oil demand in transport drops 30%, relative to our current base case. Sustainable in one sense, less so in another – the scenario leads to higher energy-related net emissions. After dropping by 4% due to supply outages in the Gulf, resilient coal demand lifts cumulative emissions above our base case from the late 2020s through to 2040. What’s the impact on global oil and gas demand? Significant for both. The scenario driver is that import-dependent countrie
