#美军封锁霍尔木兹海峡 What impact would the US blockade of the Strait of Hormuz have on the global economic markets

If the US were to blockade the Strait of Hormuz, it would send a shockwave through the global economy. It carries about one-fifth of the world's oil and liquefied natural gas shipments, earning it the reputation of being the "world's oil valve."
⚡️ Energy Market: Price Surge and Supply Disruptions
Disruptions in the passage through this strait have caused sharp increases in energy prices. After the conflict erupted, Brent crude oil prices briefly surged past $119 per barrel, and after the US announced the blockade, prices jumped more than 8%, returning above $100. If the blockade lasts more than 25 days, Middle Eastern oil-producing countries may be forced to halt production, and oil prices could break through $200 per barrel. The European natural gas benchmark price also soared by 18%, and there is even a risk of a systemic shortage of aviation fuel.
📉 Global Economy: Stagflation Risks and Recession Shadows
The blockade would impact the global economy through two pathways:
· Driving up inflation: Rising energy prices increase production and logistics costs, ultimately passed on to consumers. IMF President warned, "All roads lead to rising prices and slowing growth."
· Suppressing growth: Energy is the lifeblood of the economy; its soaring costs will inhibit investment and consumption. The World Food Programme estimates that if oil prices stay above $100, nearly 45 million more people worldwide could fall into food crises.
💸 Financial Markets: Increased Volatility and Flight to Safety
Geopolitical risks instantly change the flow of global funds:
· Stock markets under pressure: US stock futures fell 1.1%-1.3%, and Japanese and Korean markets also opened lower.
· Commodities and currencies: Gold prices briefly dropped below $4,700 per ounce, and the US dollar index strengthened due to risk aversion.
· Bond markets: Concerns about stagflation intensified, with the US yield curve flattening, as short-term yields rose faster than long-term yields.
🚢 Supply Chain: Cost Surge and Reordering
· Freight costs soar: Average oil tanker charter rates increased by 30%-60%, with some routes seeing freight costs rise 11 to 12 times.
· Insurance premiums spike: War risk insurance for single voyages under extreme risk could reach $500k to $1 million.
· Logistics network disruptions: Both the Strait of Hormuz and the Red Sea routes are blocked, forcing shipping companies to abandon just-in-time models and shift toward a "safety-first" redundant supply chain approach.
🌏 Impact on Major Economies
· United States: Although claiming to be "energy independent," its dependence on the Strait of Hormuz is deeper than publicly acknowledged by Trump. The blockade would push up domestic inflation and recession risks, confirmed by the latest Federal Reserve meeting minutes.
· China: As the world's largest crude oil importer, nearly half of China's oil imports pass through this strait, directly threatening energy security. China has begun to utilize strategic oil reserves and accelerate diversification of energy imports to cope.
· Europe: Highly dependent on Middle Eastern energy, especially sensitive to soaring energy prices, and has already faced urgent warnings of systemic aviation fuel shortages.
💎 Summary
The blockade of the Strait of Hormuz is essentially a global energy crisis triggered by geopolitical tensions. It could evolve into a severe test for the global economy through multiple channels such as energy, finance, and supply chains. If the deadlock persists, the risk of a global recession will sharply increase.
