US and Iran Trade Conflicting Claims of Missile Strikes as Strait of Hormuz Shipping Halts

What Happens Next

• →Brent crude benchmarks spike 15-25% within weeks as tanker traffic through the Strait of Hormuz — carrying roughly 20% of global oil supply — halts or severely contracts.
• →War-risk insurance premiums for Persian Gulf-bound vessels surge to levels comparable to or exceeding 2019 tanker attack rates, forcing smaller shipping firms to suspend Gulf routes entirely.
• →US Strategic Petroleum Reserve faces political pressure for emergency drawdowns to stabilize domestic fuel prices ahead of consumer impact, reducing the reserve's buffer capacity.
• →Ceasefire negotiations referenced by Al Jazeera collapse as hardliners in both Washington and Tehran use the exchange of fire to justify escalatory postures, narrowing diplomatic off-ramps.

Near-term: In 1-3 months, Brent crude rises sharply while global tanker rerouting around the Cape of Good Hope adds 2-3 weeks to Asia-Europe transit times, straining refined product inventories in import-dependent economies such as Japan and South Korea. Long-term: In 2-5 years, sustained chokepoint risk accelerates investment in overland pipeline capacity from the Gulf to Red Sea and Indian Ocean terminals, and major Asian importers diversify crude sourcing toward West Africa, the Americas, and Arctic-route Russian supply.
