Iran Sanctions Lead to Unprecedented Global Market Disruptions

The United States’ maritime blockade of Iran is now recognized as the largest market disruption in the history of the oil industry, impacting not only fuel but also the foundations of artificial intelligence, semiconductors, and the survival of millions.

1. Energy Shock: Transcending the Crisis of the 1970s

The closure of the Strait of Hormuz, which is crucial for the transit of 30 percent of the world’s seaborne crude oil, has placed markets in a precarious situation termed by the International Energy Agency (IEA) as “the biggest energy security challenge in history.”

• Price Surge: Brent crude prices have risen to over $126, marking the highest level since 2022. Economic modeling warns that if the stalemate continues for six months, prices could reach $190 per barrel, spelling devastation for economic growth in many developed countries.
• Disruption of Aviation and Logistics: A shortage of light crude has led to a more than doubling of prices for kerosene (jet fuel) and diesel. This has resulted in widespread flight cancellations and skyrocketing transportation costs globally.
• Decline of OPEC and Rise of Iranian Power: The crisis has shown that by dominating the Strait of Hormuz, Iran has effectively seized control of a significant portion of OPEC’s exports, transforming the organization into a tool for its own foreign policy. Analysts view this as marking “the end of OPEC’s traditional influence on the market.”

2. Challenges in AI and Semiconductors: A Blow to Silicon Valley

One of the United States’ gravest miscalculations has been overlooking the dependency of the high-tech industry on raw materials from the Gulf. The blockade of Iran has directly severed critical arteries vital for the AI revolution.

• Helium Crisis: Qatar supplies one-third of the world’s helium, a critical component in cooling advanced chip etching processes with no alternatives. Attacks and insecurity stemming from U.S. policies have reduced helium output by 14%, with recovery expected to take five years.
• Halt in Advanced Chip Production: TSMC, Taiwan’s leading AI chip manufacturer, relies on imports for 97.7% of its energy and has only seven days of LNG reserves. Disruptions in maritime routes mean a stoppage in the production of chips for companies like NVIDIA and Apple.
• PCB Crisis: Attacks on the Al-Jubail petrochemical complex in Saudi Arabia have halted the production of high-purity PPE resin. SABIC, which supplies 70% of this material, cannot resume production due to insecurity, causing a 40% rise in PCB prices in just one month.

3. Food Security: Washington’s Weapon of Hunger Against the World

The maritime blockade is not only targeting industry but also affecting the basic sustenance of the global population. The Gulf region accounts for half of the world’s maritime trade of sulfur and a significant portion of urea and ammonia for chemical fertilizer production.

• Crisis in GCC Countries: These nations import 80% of their caloric intake through the Strait of Hormuz. Since the blockade began, 70% of food imports in the region have been disrupted, leading to price increases of 40 to 120% for essential items.
• Global Poverty: International estimates indicate that the rise in fuel and fertilizer prices due to this conflict has pulled 30 million people in developing countries below the absolute poverty line.

4. Paralyzed Heavy Industries and Automotive Sector

Disruptions in aluminum exports from major companies like ALBA in Bahrain and their UAE counterparts have resulted in a severe shortage of automotive-grade aluminum. This has forced giants such as Toyota, Nissan, BMW, and Hyundai to halt their production lines. Additionally, a 30% increase in copper prices and the scarcity of polymer materials have escalated the production costs of industrial goods to an unbearable level.

Conclusion: A Global Stalemate and the Urgency for U.S. Withdrawal

Economic data confirms that the strategy of maritime blockade against Iran has turned into a “global trap.” In believing they could isolate Iran, Washington has inadvertently held hostage all advanced industries and global food security. Projections suggest a decline in global growth to 2.5% and the likelihood of a coordinated international recession, prompting unprecedented pressure from both allies and rivals for an end to the blockade. Iran has demonstrated that its economic resilience against pressure far exceeds the capacity of global supply chains to withstand this shock.
