Will the United States and Iran reach a formal nuclear agreement by the end of Q4 2026?
What moved
A 95 percent drop in Hormuz transit traffic has reshaped global shipping routes and costs; the near-total cessation of the strait's throughput removes roughly a fifth of seaborne oil from its primary outlet with no maritime alternative.
The market transmission
This is a fundamental disruption to the oil export pathway from the Persian Gulf. With Hormuz carrying no traffic, Gulf crude must route through overland pipelines to Fujairah or wait for resolution, constraining supply into global markets. Tanker rates on affected routes have repriced sharply, and refiners reliant on Gulf feedstock face either higher transport costs or supply substitution. The magnitude, 95 percent, suggests the closure is near-complete and sustained, not a temporary bottleneck.
What would change this
Hormuz has no maritime workaround; the only partial alternatives are the Saudi East-West pipeline and the Abu Dhabi line to Fujairah, both of which have finite throughput and cannot absorb the full volume normally transiting the strait. If the closure holds, spare production capacity outside the Gulf becomes the binding constraint on global oil supply. A 95 percent drop is an extreme figure and suggests either political closure or military interdiction, both of which imply duration risk rather than a clearing shock.
