What moved
South Korea began preparations for a possible naval deployment to Hormuz; no commitment made and no ships deployed yet, leaving the impact on transit security and oil flows contingent on a decision not yet taken.
The market transmission
The signal is a step toward potential escort coverage in the Gulf, but remains preparatory and conditional. Hormuz carries roughly a fifth of seaborne oil, and stable transit is already priced in. A commitment to sustained escort presence could matter for tanker insurance and route confidence if regional tensions spike, but an announced deployment would likely show more price effect than preparations alone. This is positioning, not yet a flow change.
What would change this
Preparations are not deployment, and deployment would not be enforcement of a closure. The statement reflects US pressure on an ally rather than a change to Iranian or regional state capacity to interdict traffic. Hormuz transits remain open. The threshold for market repricing is sustained disruption to commercial traffic, not the presence of naval assets.
