The war in Iran is choking the Strait of Hormuz, which handles 20% of global oil. This disruption impacts nearly three times more oil volume than Russia's exports at the start of the Ukraine war, posing a significantly larger threat to the global economy and inflation.

20-30% of the world's fertilizer passes through the Strait of Hormuz. Iran's ability to block this passage means the conflict is not just an oil crisis but a direct threat to the global food supply, potentially leading to a worldwide famine.

A likely outcome of the conflict is Iran establishing control over the Strait of Hormuz and charging tolls for passage. This would mirror Russia's control over the Northern Sea Route, fundamentally altering freedom of navigation and creating a new economic reality where a state actor monetizes a critical global chokepoint.

The shift away from a unipolar world is not a managed process. It's a chaotic reorganization driven by conflicts over essential resources like energy. Nations are forced to abandon old allegiances and form new, pragmatic alliances to protect their core interests.

Post-Cold War globalization and its resulting just-in-time supply chains relied on the implicit security of maritime choke points, a role largely guaranteed by the US Navy. As regional conflicts rise and US commitment becomes uncertain, this foundational assumption of safe passage is collapsing, forcing a reassessment of global trade.

Energy disruptions in the Strait of Hormuz create a cascade effect far beyond fuel prices. The resulting shortages impact petrochemical and fertilizer production, threatening key inputs for everything from manufacturing and electronics to agriculture and basic services like cooking gas for restaurants.

The successful closure of the Strait of Hormuz, a critical global choke point, with relatively little military effort creates a permanent change in risk assessment. This 'black swan' event proves the vulnerability of global supply chains, forcing nations and companies to rethink and de-risk their long-term strategies, regardless of when the strait reopens.

The conflict is not an isolated event but a symptom of the world transitioning away from a single US superpower. This new era features competing power blocs like the US, China, and India, a return to a more historically typical state of global affairs.

The ongoing war in the Middle East, particularly its impact on energy prices via potential disruptions like the closure of the Strait of Hormuz, is now the primary factor shaping the global macro outlook. This negative supply shock significantly increases the probability of a global recession.
