Iran Closes Strait of Hormuz After Striking Vessel on Unauthorised Route

What Happens Next

• →Brent crude prices spike 30-50% within weeks as roughly 20% of global seaborne oil supply is removed from the market, with Asian importers (China, Japan, South Korea, India) facing the sharpest supply deficits.
• →Gulf Cooperation Council states and Iraq lose primary export capacity, triggering drawdowns of strategic petroleum reserves by the US, EU, Japan, and South Korea to stabilize spot markets.
• →US Central Command increases naval deployments to the Persian Gulf and Arabian Sea, raising the probability of direct US-Iran military confrontation and prompting GCC states to elevate force postures.
• →Central banks in import-dependent economies — particularly the Bank of Japan, Reserve Bank of India, and ECB — face pressure to pause or reverse rate-cutting cycles as energy-driven inflation re-accelerates.

Near-term: Brent crude rises 30-50% within 1-3 months; strategic petroleum reserve releases by major importers partially offset supply loss but fail to fully stabilize prices. US naval escalation in the Gulf increases risk of direct confrontation with Iran. Long-term: Over 2-5 years, multi-billion-dollar investments flow into trans-Arabian bypass pipeline infrastructure and LNG export terminals on the Red Sea and Arabian Sea coasts, permanently reducing the share of global oil transiting the Strait of Hormuz.
