A little-noticed expense tied to shipping oil through the Strait of Hormuz has skyrocketed nearly 1,900%, according to analysis by Devere Group. The surge signals a level of risk that could prove more important than oil's latest rally. Oil prices jumped on July 22 as tensions around the strategic waterway continue to intensify.
The 1,900% spike
The cost in question is war risk insurance premiums for tankers passing through the Strait of Hormuz. Devere Group's analysis shows the premium has climbed from a negligible base to a level that now adds millions of dollars to each voyage. The increase reflects growing fears that any escalation in the region could lead to attacks on commercial vessels or outright blockades.
Why the Strait of Hormuz matters
About a fifth of the world's oil moves through the narrow strait between Iran and Oman. Recent weeks have seen a series of incidents involving tankers, drone strikes, and diplomatic tensions. On July 22, benchmark oil prices jumped as traders priced in a higher probability of supply disruption. But the hidden cost surge suggests the market may be underestimating the real risk.
What the surge means for oil markets
Some analysts argue that the 1,900% jump in shipping costs is a more direct measure of geopolitical risk than the oil price itself. While crude prices can be influenced by many factors—including inventories, demand forecasts, and OPEC decisions—war risk insurance is a pure bet on conflict. If the premium stays elevated or climbs further, it could eventually feed into higher fuel costs for consumers and tighter margins for refiners.
The next test for the market will come when the next batch of shipping rates is published. Traders are watching for any further escalation in the region, as a single incident could send both insurance costs and oil prices sharply higher.
