The Strait of Hormuz crisis is providing the starkest possible demonstration of the world’s continued dangerous dependence on fossil fuels — and specifically on the concentrated flow of those fuels through a single geographic chokepoint that one determined state actor can close with military force. President Trump’s calls for allied navies to defend the world’s most important oil shipping route have been met with universal hesitation, while global economies absorb the consequences of a disruption that would not be possible if the world had already made the energy transition away from the Gulf crude that the strait carries. The crisis is, among other things, an argument for accelerating that transition.
Iran launched its blockade at the end of February as retaliation for US-Israeli airstrikes, generating the most severe oil supply disruption in history. One-fifth of global oil exports ordinarily flow through the passage. Tehran has attacked sixteen tankers, declared vessels heading for American or allied ports to be legitimate targets, and threatened to mine the waterway. The vulnerability that Iran is exploiting is structural — the world has built its energy system around the regular flow of oil through the Hormuz chokepoint, and that structural vulnerability cannot be eliminated quickly regardless of how the current crisis is resolved.
The responses of named coalition partners have reflected the practical impossibility of quickly resolving structural energy vulnerabilities through military action. France ruled out sending ships while fighting continued. The UK explored lower-risk options. Japan described a very high deployment threshold. South Korea pledged careful deliberation. Germany questioned the EU’s Aspides mission’s effectiveness. No government committed forces. The pattern of cautious non-commitment reflects not just military risk abut the absence of any quick military fix to a problem whose root cause is structural dependence on a vulnerable supply route.
The long-term lesson of the Hormuz crisis for energy policy is clear: the world needs to reduce its dependence on oil flows through single geographic chokepoints. Renewable energy development, nuclear power expansion, energy efficiency improvements, and strategic diversification of supply routes all reduce the vulnerability that Iran is currently exploiting. The economic damage from the current crisis — surging oil prices, supply chain disruptions, and the broader macroeconomic consequences — is itself an argument for the investments that would make future crises of this type less catastrophic.
China’s diplomatic engagement with Tehran, while aimed at the immediate crisis, also reflects Beijing’s own recognition of the energy vulnerability that the crisis has exposed. As a major oil importer through the strait, China has every reason to both resolve the current crisis and invest in the long-term energy diversification that would reduce its future vulnerability. The Chinese embassy confirmed China’s commitment to constructive regional engagement. US Energy Secretary Chris Wright expressed hope that China would prove a constructive partner in restoring access to the world’s most critical oil corridor — while the broader energy transition agenda that the crisis is accelerating proceeds on its own urgent timeline.
