Strait of Hormuz blockade triggers global supply chain chaos and price surges

Disruptions in the Strait of Hormuz are sending shockwaves through global supply chains, pushing up prices for everything from food to medicine. The closure has cut off key routes for oil, gas, and chemicals, forcing industries to adapt as costs climb. Experts warn the ripple effects could soon hit consumers in multiple sectors.

The Strait of Hormuz serves as a critical passage for essential goods, including a quarter of the world's helium and over a fifth of its fertilisers. With the route blocked, helium shortages may worsen, further driving up costs for semiconductors and medical tests. Meanwhile, urea and fertiliser shipments—35% and 20% of global supply, respectively—face delays, threatening agricultural output.

Natural gas prices in Europe and Asia have already doubled since the conflict began, keeping US energy costs elevated. Diesel price spikes and fertiliser shortages could push food prices higher, particularly for perishable goods. Aluminium costs have also surged due to US tariffs and the blockade, adding pressure on homebuilding expenses.

India, which produces a fifth of the world's drugs and two-thirds of its vaccines, may see air freight disruptions raise medication costs. While pharmaceutical ingredients and vaccines remain unaffected so far, general logistics delays and rerouted cargo—like Maersk's suspended Gulf routes—are increasing shipping times and expenses. Other regions have ramped up production of critical materials, but this has only led to further price hikes.

The Strait of Hormuz closure is creating a broader inflation risk, affecting industries beyond fuel. Crude oil byproducts, vital for plastics and petrochemicals, also rely on Middle Eastern shipments through the strait. Without alternative routes or production sites in place, businesses and consumers may face prolonged cost pressures across multiple markets.
