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

If the US were to block 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, making it the true “world’s oil valve.”
⚡️ Energy markets: Price spikes and supply disruptions
Bottlenecks in passage through the strait have already caused energy prices to surge sharply. After the outbreak of the conflict, Brent crude oil prices briefly rose above $119 per barrel; and after the US announced the blockade, prices jumped by more than 8% and returned 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. Europe’s natural gas benchmark price also rose by as much as 18%, and there is even a risk of a “systemic” shortage of aviation fuel.
📉 Global economy: The risk of stagflation and the shadow of recession
The blockade would hit the global economy through two paths:
· Raise inflation: Higher energy prices increase production and logistics costs, which are ultimately passed on to consumers. The IMF managing director warned, “All roads lead to rising prices and slower growth.” · Suppress growth: Energy is the lifeblood of the economy, and soaring costs would curb investment and consumption. The World Food Programme estimates that if oil prices stay above $100, the world could see nearly 45 million more people fall into food crises.
💸 Financial markets: Turbulence intensifies and investors shift to safe havens
Geopolitical risk instantly changes where global capital flows:
· Stock markets under pressure: US stock index futures fell 1.1%-1.3%, and stock markets in Japan and South Korea also opened lower. · Commodities and currencies: Gold prices briefly fell below $4,700 per ounce, and the US dollar index strengthened as risk-aversion sentiment grew. · Bond markets: Concerns about “stagflation” intensified, and the US Treasury yield curve flattened, as short-term yields rose faster than long-term yields.
🚢 Supply chains: Costs surge and order is reshaped
· Freight costs soar: The average increase in oil tanker charter rates reached 30%-60%, and on some routes freight rates even rose by 11 to 12 times. · Insurance premiums explode: War-risk insurance for a single voyage under extremely high-risk conditions could be as high as $500,000 to $1 million. · Logistics networks disrupted: Both the Strait of Hormuz and the Red Sea shipping lanes are blocked, forcing shipping companies to abandon “just-in-time” and switch to a “safety-first” redundant supply chain model.
🌏 Impact on major economies
· United States: Although it calls itself “energy independent,” its reliance on the Strait of Hormuz is much deeper than what Trump has publicly acknowledged. A blockade would raise domestic inflation and recession risks, and the Fed’s latest meeting minutes have already confirmed this negative impact.
· China: As the world’s largest crude oil importer, nearly half of China’s crude oil imports must pass through this strait, directly putting energy security at risk. China has begun to draw on strategic oil reserves and speed up a more diversified layout for energy imports to respond.
· Europe: Highly dependent on energy from the Middle East and especially sensitive to soaring energy prices, it has already faced urgent warnings of a systemic aviation fuel shortage.
💎 Summary
The blockade of the Strait of Hormuz, in essence, is a global energy crisis triggered by geopolitics. It will evolve into a severe test for the global economy through multiple channels such as energy, finance, and supply chains. If the stalemate continues, the risk of a global recession will rise sharply.
