Hormuz Blockade Plan Pushes Oil Above $100 as Aluminum and Other Commodities Spike
A U.S. naval blockade on ships entering and exiting Iranian ports has sent oil above $100 a barrel and pushed aluminum to four‑year highs, officials and market reports said after prices jumped more than 7% on Monday to about $102.30 for Brent and $104.20 for West Texas Intermediate. The move, ordered by the U.S. president to tighten pressure on Iran, has sharply reduced traffic through the Strait of Hormuz — from roughly 129 ships a day before the war to about 10 a day in April — though the operation is narrower than initial fears because the U.S. Navy is allowing transits between non‑Iranian ports.
The blockade’s market ripple has been broad: aluminum, whose regional production accounts for nearly a tenth of global supply, reached its highest level in four years as factories in Asia cut output, gas stations began rationing fuel and some airlines trimmed flights amid jet‑fuel shortages. U.S. gasoline prices have already climbed above $4 a gallon, and futures markets reflected the shock — Dow futures fell roughly 477 points while S&P 500 and Nasdaq futures were down about 0.7% — underscoring how a prolonged disruption in Hormuz could turn a regional war into a wider economic shock depending on its duration and any additional chokepoints.
Observers on social media amplified the risks and divergent scenarios: some strategists warned that sustained restrictions — coupled with threats to other choke points such as Bab al‑Mandeb — could lift oil toward $150–$200 and tip the global economy into recession, while others argued higher oil would revive U.S. shale production and relieve some pressure. The human and logistical toll is also under strain: Filipino seafarers, who make up a large share of the global mariner workforce and whose demand was growing at 5–7% annually as of 2025, are likely to face intensified operational pressures as shipping volumes and crew rotations are disrupted.
