Measured from 8 Aug 2026 (event start), not the 8 Aug 2026 announcement
Airline stocks moved -8.2%, the largest reaction measured, though not statistically significant, meaning it may reflect normal market noise rather than the event itself. This is a provisional result; the full measurement window is not yet complete.

What Happened
A sanctioned tanker carrying approximately 1 million barrels of oil is sinking deeper into the sea off Oman's coast, where it has been grounded for weeks. Satellite images show progressive submersion, raising the probability of a total loss and environmental spill. The vessel is part of Iran's shadow fleet operating under sanctions.
1 million barrels removed from supply if total loss occurs; environmental event risk in high-traffic waterway; tightens already-stressed Iranian crude export capacity
Ongoing deterioration as of August 8; total loss timing unknown
Satellite imagery reviewed August 8 shows a sanctioned tanker carrying nearly 1 million barrels increasingly submerged off Oman. The vessel has been grounded for weeks; the worsening condition increases environmental and supply risk but timing of total loss is uncertain.
