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 20 million barrels of oil flowing daily through the Strait of Hormuz represent 20% of global supply. A blockade constitutes a disruption four times larger than the Iranian Revolution or Yom Kippur War embargoes, with no simple replacement.

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.

Beyond insurance and logistics, the paramount concern is human life. In the Strait of Hormuz, a vessel was immediately abandoned by its crew after being hit, without attempting to fight the fire. This highlights that crew willingness to enter a high-risk zone is the ultimate, non-negotiable variable in supply chain continuity.

Despite rising oil prices, there's no evidence of a supply shortage. Physical market indicators have even softened. The rally is fueled by investors buying "insurance" against potential geopolitical disruptions, creating a risk premium that doesn't reflect the market's weak underlying fundamentals.

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.

Iran effectively weaponized the Strait of Hormuz not with mines, but by creating enough uncertainty to make UK-based insurance companies pull out. This demonstrates how financial systems can be leveraged as powerful geopolitical choke points.

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.
