Will the Iran war crash the global economy?
Energy shock, market volatility and uncertain duration
The military operation against Iran has already pushed oil above $100 per barrel in multiple trading sessions, triggered emergency meetings among the G7 and produced sharp swings in stock markets. That combination—supply disruption, shipping risk around the Strait of Hormuz and strikes on refineries and fuel depots—creates a near‑term economic shock that can ripple through prices, trade costs and consumer confidence.
Immediate and medium‑term effects have included:
- Spiking gasoline and jet‑fuel prices that drive higher costs for households and airlines
- Volatile equity markets as investors price in slower growth and higher inflation
- Strain on global supply chains where energy is a key input, raising the prospect of widening price shocks
Policy consequences are already in play. Central banks face a delicate trade‑off: rising energy costs can lift inflation expectations even as the U.S. jobs picture weakens, complicating decisions about interest rates. Governments are weighing strategic responses—releasing emergency oil reserves, negotiating alternative shipping arrangements, or offering targeted relief—to blunt the impact on consumers and critical industries.
How bad it gets depends on three variables:
- How long hostilities disrupt Gulf oil exports and shipping lanes;
- The extent of damage to producing facilities and the time needed to restore them; and
- Whether the conflict widens to involve more regional producers or major consumers.
If the disruption is short and markets see credible spare‑supply measures, price and growth effects could be contained. But if the Strait of Hormuz remains effectively closed or key production stays offline for months, the world risks a prolonged energy shock that could trigger stagflation‑like conditions. At this stage, economists and officials disagree on the likely timeline; policymakers are acting to limit immediate harms while preparing for a range of scenarios.
