The disruption in the Strait of Hormuz isn't a formal closure. Instead, shippers and producers are adopting a "wait and see" approach, halting flows due to reports of damaged ships and skyrocketing insurance premiums, effectively creating a self-imposed blockade.

The recent surge in oil prices to $78 per barrel is not just vague fear. Analyst models suggest the market has priced in an $8-13 risk premium, which corresponds directly to the expected impact of a complete, four-week closure of the Strait of Hormuz, providing a concrete measure of market sentiment.

In a naval blockade, the real timeline for market impact isn't political rhetoric but the physical limits of onshore storage. Producers are forced to cut output within days or weeks once storage fills, a much shorter timeframe than leaders might suggest for a conflict.

The Middle East conflict has moved beyond risk to a physical blockade of the Strait of Hormuz. With commercial tankers no longer transiting, nearly 20% of global oil is cut off from markets. This supply disruption, not just a risk premium, is driving oil prices toward $100/barrel.

The impact of an oil supply disruption on price is a convex function of its duration. A short-term closure results in delayed deliveries with minimal price effect, while a prolonged one exhausts storage and requires triple-digit prices to force demand destruction and rebalance the market.

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.

While many fear production shutdowns, a more significant and probable risk is a logistical shock from shipping disruptions. Even modest delays in tanker transit times could effectively remove millions of barrels per day from the market, causing a significant price spike without a single well being shut down.

The conflict's primary impact on oil is not that supply is offline, but that its transport through the Strait of Hormuz is blocked. This distinction is key to understanding price scenarios, as supply exists but cannot be delivered.

While global spare oil capacity exists as a buffer, it is heavily concentrated in Saudi Arabia, the UAE, and Kuwait. During a conflict, if the Strait of Hormuz is effectively closed, this capacity becomes physically trapped and cannot be deployed to global markets, nullifying its role as a price stabilizer.
