The global oil market has two parts: pipeline and seaborne. Price volatility and formation are dominated by the more flexible seaborne market, which can be redirected to meet global demand, making it the critical component for setting prices, despite only being 60% of total consumption.

The world has twice as much regasification (import) capacity as it does liquefaction (export) capacity. This is because import terminals are 10x cheaper to build. This structural imbalance means that during supply shocks, two buyers often compete for every available cargo, driving prices up sharply.

Western leaders mistakenly focus on securing raw material sources ('feedstock'), believing mining rights equal supply chain control. The reality is that China's dominance in midstream processing makes the mine's location irrelevant, as they control the ability to turn ore into usable material.

The critical threat to aluminum production isn't shipping finished goods, but the reliance on imported alumina. Regional smelters hold only 20-30 days of raw material inventory, meaning a sustained shipping disruption will force widespread production shutdowns within weeks, severely tightening the market.

It is far more expensive to cryogenically chill and ship natural gas than to convert it into a solid, granular product like urea at the source. This supply chain logic explains why fertilizer plants are concentrated in regions with cheap gas, like the Middle East, rather than near end-user markets.

The disruption in the Persian Gulf affects not just the headline commodities of oil and gas, but also crucial dry bulk goods. Outbound fertilizers and aluminum, along with inbound raw materials for production, are significantly impacted, causing spikes in global markets for these specific goods.

Even a short-term crisis can create a prolonged aluminum shortage. It takes only a month to shut down a smelter, but restarting that same facility can take six months. This operational asymmetry means that supply is destroyed far more quickly than it can be restored, locking in market tightness.

China's global dominance isn't in owning mines, but in controlling the midstream refining and smelting processes. This creates a critical choke point for the West's supply of essential materials for defense, AI, and electrification, as they control 50-98% of processing capacity for key metals.

The major outage at the Grasberg mine, which supplies 3% of the world's copper, is turning a previously balanced market into a significant deficit for 2025 and 2026. This highlights supply chain fragility, as there were no existing surpluses to absorb the shock.
