**Summary**: Satellite imagery shows a 65 km oil slick along Oman’s coast from Iranian attacks on tankers transiting the Strait of Hormuz. The evidence of significant environmental and physical damage underscores the severity and persistence of the Gulf shipping threat, reinforcing higher war risk premia for crude and product flows through the region.

## Detail

New satellite images reveal an oil slick stretching approximately 65 kilometers along Oman’s coastline, attributed to Iranian attacks on oil tankers that had crossed the Strait of Hormuz. This is the first concrete, visual confirmation of substantial pollution and likely structural damage to vessels from the recent harassment and strike campaign. It indicates that incidents in the Gulf are not isolated warning shots but have resulted in major spills, implying severe damage to at least one large tanker and possibly more.

From a supply‑side perspective, the slick itself does not materially change global balances, but it confirms that recent attacks are capable of taking VLCCs/Suezmaxes out of operation for extended repairs or even total loss. If we assume only a handful of such ships are impacted, near‑term lost liftings might be in the range of several hundred thousand barrels per day for weeks, but the more important effect is psychological and regulatory: insurers, P&I clubs, and charterers will reassess risk, elevating war risk premia, rerouting, or even suspending calls to certain Gulf terminals.

This evidence of environmental damage also increases political pressure on Gulf states and Western navies to respond, raising the risk of further escalation. That dynamic tends to support a higher and stickier risk premium in Brent and Dubai benchmarks, as well as in time spreads (backwardation) as physical buyers bid up prompt barrels outside the Gulf. Refiners in Europe and Asia may accelerate diversification away from exposed routes, supporting Atlantic Basin grades and US Gulf Coast exports.

In shipping, crude and product tanker rates for non‑Hormuz routes are likely to remain elevated as fleet deployment shifts, while Gulf‑linked trades may require significantly higher day rates and insurance, increasing delivered crude and product prices. Historically, visible tanker damage events in the region (e.g., 2019 Fujairah and Gulf of Oman incidents) have produced 1–3% same‑day moves in Brent and meaningful spikes in war risk surcharges.

The spill reinforces that Hormuz disruption risk is not just rhetorical but operational and environmental, extending the expected duration of elevated risk pricing in oil and tanker markets as long as attacks persist and cleanup continues.
