Could the Iran War Plunge Britain into a 1970s-Style Energy Crisis?
From the coal crisis under Ted Heath to Tony Blair's fuel blockades, the UK economy is no stranger to energy shocks. However, as geopolitical tensions escalate, the current spike in oil and gas prices caused by the Iran war presents a potentially more severe threat. This conflict might differ significantly from past disruptions, highlighting the critical value of clean, green, and reliable energy sources like renewables and nuclear power.
What Causes an Energy Shock?
Historically, turmoil in the Middle East has been a primary driver, given the region's dominance in global energy supplies until the recent rise of US fracking and shale gas. For instance, the 1956 Suez Crisis nearly led to petrol rationing in Britain after a collaborative invasion of Egypt disrupted shipping. Similarly, the 1973 Yom Kippur war saw Gulf states impose an oil embargo on Western allies, quadrupling prices and, combined with a national coal strike in the UK, resulting in energy cuts and a three-day working week that toppled Edward Heath's government.
In 1979-80, the Iranian revolution drove oil prices higher, insulating Britain somewhat through North Sea oil but turning sterling into a petrocurrency that hurt exports. Subsequent crises, like the Gulf wars and the 2022 Russian invasion of Ukraine, followed similar patterns of price spikes and economic strain.
Are Energy Crises Always Global?
Not necessarily. Incompetent domestic policies can also trigger shortages, even in energy-rich nations like Iran and Venezuela. A notable example occurred in 2000 when disgruntled truckers blockaded UK oil refineries over fuel duties, leading to petrol shortages that threatened emergency services. The Blair government eventually relented under pressure, showcasing how internal factors can exacerbate vulnerabilities.
What Happens After an Energy Crisis?
Typically, as conflicts subside, oil and gas prices retreat, allowing economic recoveries. Geopolitical shifts, such as the 1980s oil glut from the Iran-Iraq war, can also ease pressures. High prices often spur exploration and investment, while the growth of renewables reduces dependence on volatile fossil fuels. Over time, advanced economies have lowered oil intensity through fuel efficiency, better insulation, and alternative energy sources.
Could This Time Be Different?
Unfortunately, yes. The current Iran war is unprecedented in its regional scope, involving direct combat between Iran, America, and Israel, with superpowers like China invested in the outcome. Coupled with the ongoing war in Ukraine, where Russia benefits from higher oil prices, this conflict may signal a new front in a broader global struggle.
Such circumstances could lead to prolonged economic dislocations rather than short-lived crises. The political fallout is unpredictable, and even if global conflict is avoided, the Starmer government may face severe constraints in supporting the economy. Another bout of stagflation—low growth with high inflation—seems likely, echoing past hardships without clear blame but with electoral consequences.
In summary, while Britain has weathered energy shocks before, the Iran war's unique scale and geopolitical complexities pose a heightened risk, underscoring the urgent need for resilient energy strategies.
