Global Energy Crisis Surges as Iran Conflict Disrupts Oil Supply

A geopolitical choke point has forced a debate about whether energy security is solved by markets, institutions, or strategic government action.

A rapid shutdown and disruption of traffic through the Strait of Hormuz after military strikes and retaliatory attacks has removed roughly one-fifth of global oil flows and large volumes of LNG from world markets. Governments, international agencies, and markets disagree on the interpretation and remedy: some actors treat the crisis as an unprecedented supply shock that requires centralized, institution-led coordination (strategic reserves, sanctions enforcement, diplomatic containment and new chokepoint protections), while others emphasize market signals and supply-side diversification (alternative shipping routes, increased production outside the Gulf, and accelerated investment in domestic energy). Underneath these disagreements are deeper conflicts about which institutions are credible, how much short-term intervention is legitimate, and whether long-term energy transformation should be accelerated as a strategic imperative or subordinated to immediate supply relief.

Key facts

  • About 20% of global oil supply has been disrupted due to the closure of the Strait of Hormuz and related shipping interruptions caused by the Iran conflict.
  • Approximately 11 million barrels per day (bpd) of crude oil and oil product supply, plus around 300 million cubic meters of LNG per day, were lost in the month following the conflict's outbreak—more than 10% of global oil consumption.
  • Oil prices surged past US$100 per barrel (Brent) in early March, driven by fears of prolonged disruption even where immediate regional supply remained adequate.
  • The IEA described the situation as the 'greatest global energy security threat in history' and warned the shock is deeper than 1973 or the Ukraine war, given the scale of losses and chokepoint disruptions.
  • About one-fifth (20%) of global crude oil and natural gas supply was suspended due to Strait of Hormuz closure and attacks on energy infrastructure, causing major export suspensions from Gulf producers.
  • Brent crude crossed above US$100 per barrel in early March for the first time since 2022, reflecting market fears about prolonged supply disruptions.
  • Countries including South Korea, Thailand, Bangladesh, and Pakistan implemented measures such as price caps and fuel rationing in response to rising petroleum prices driven by the conflict.
  • The IEA warned the present situation was the 'greatest global energy security challenge in history,' while global oil output dropped by about 11 million bpd and LNG flows fell by ~300 million cubic meters per day in the month after the conflict began.
  • The war has raised global inflationary pressure, particularly in import-dependent, energy-vulnerable economies such as Egypt and Turkey, contributing to currency weakening and food security risks via higher fertilizer costs.
  • The Strait of Hormuz has been largely shut or disrupted since late February 2026 following joint military strikes by U.S. and Israel and subsequent Iranian retaliation, causing major export suspensions and a collapse of regional shipping traffic.
  • Iran produced about 3.5 million bpd of crude and ~0.8 mb/d condensate in 2025 (roughly 4% of global oil supply) and exported roughly 1.7 mb/d crude plus other products, making disruptions to its production or transit routes globally significant.
