The Risk the War in Iran Poses to the Global Economy

Key Concepts

• Operation Epic Fury: The joint US-Israel military operation targeting Iran’s nuclear, ballistic, and naval capabilities.
• Strait of Hormuz: A critical maritime chokepoint connecting the Persian Gulf to the Gulf of Oman, through which ~20% of global crude oil passes.
• Energy Market Volatility: The sensitivity of global oil and gas prices to geopolitical instability in the Middle East.
• Sanctions: Economic restrictions imposed by the US and UN to limit Iran’s financial and military capabilities.
• Safe Haven Assets: Financial instruments (like US Treasury bonds) that investors typically seek during crises, though currently impacted by inflation fears.
• Capital Flight: The rapid movement of assets or money out of a country due to political or economic instability.

1. The Conflict and Its Objectives

The US and Israel launched "Operation Epic Fury" with the stated goals of neutralizing Iran’s nuclear program, destroying its ballistic missile arsenal, and degrading its proxy networks. The operation resulted in the death of Supreme Leader Ayatollah Ali Khamenei. While the US military action was swift, the conflict has escalated, with Iran retaliating against neighboring countries hosting US troops. Analysts suggest the underlying intent is a complete regime change, with projections indicating the military operation could last four to six weeks.

2. Economic Significance of Iran

Despite being heavily sanctioned and relatively isolated, Iran remains a pivotal player in the global energy market:

• Oil Reserves: Iran holds the world’s third-largest oil reserves (12% of global total) and produces roughly 4% of the world’s oil.
• Black Market Reliance: Despite sanctions, Iran exports over 80% of its oil to China, totaling approximately 520 million barrels in 2025.
• Economic Size: Iran’s GDP is roughly one-fifth the size of Canada’s, reflecting the long-term impact of international trade restrictions.

3. The Strait of Hormuz: A Global Chokepoint

The most significant economic risk stems from the closure of the Strait of Hormuz by the Islamic Revolutionary Guard Corps (IRGC).

• Impact: The strait handles 31% of all seaborne crude and 20% of global daily oil supply.
• Disruption: Following the closure, eight vessels were struck, and major shipping companies suspended transit.
• Price Surge: West Texas Intermediate (WTI) rose nearly 30% to $90/barrel, and Brent crude rose 25% to $91/barrel. Experts warn that a month-long disruption could push prices into triple digits.
• Broader Commodities: The strait is also a conduit for liquefied natural gas (LNG) and urea (nitrogen-based fertilizer), causing natural gas futures to jump 60% and fertilizer prices to rise 25%.

4. Mitigation and Alternative Routes

While the closure is severe, some infrastructure exists to bypass the strait:

• Pipelines: Saudi Arabia has pipeline capacity for 5 million barrels per day to the Red Sea.
• Risks: These alternatives are threatened by Houthi rebels in Yemen. Rystad Energy estimates that even with these routes, global supply could drop by 8–10 million barrels per day (nearly 10% of global supply).

5. Impact on the US Economy

Contrary to the belief that war is always "good for business," the US faces several negative economic pressures:

• Inflation: Increased government spending and supply chain disruptions (higher freight rates) are expected to drive inflation.
• Interest Rates: The Federal Reserve may be forced to hike rates to combat inflation, potentially offsetting the usual "safe haven" status of US Treasury bonds.
• Debt: Increased military spending, combined with lost tariff revenue, is expected to exacerbate the US national debt.
• Stock Market: While short-term volatility is expected, historical data from the Institute of Economics and Peace suggests that geopolitical conflicts do not have a consistent long-term correlation with stock market valuations.

6. Long-term Projections and Synthesis

Using the Keel Institute’s "Price of War" calculator, a 3.5-year conflict could cost Iran $1 trillion in lost capital and $600 billion in GDP, while the rest of the world could see a cumulative GDP loss exceeding $1 trillion.

Conclusion: The conflict in Iran represents a high-stakes disruption to the global economy. Even with US efforts to escort ships and potential production increases from OPEC+, the combination of energy supply shocks, rising inflation, and the potential for a power vacuum in Iran creates significant uncertainty. Investors are cautioned against making long-term decisions based on short-term geopolitical headlines, as the duration and scope of the conflict remain highly unpredictable.
