Hormuz Strait oil traffic way down; Hassett: One tanker matters

Despite an announced two-week ceasefire between the United States and Iran, commercial tanker traffic through the Strait of Hormuz remains markedly depressed; President Donald Trump said the pause was conditional on the waterway being reopened "COMPLETE, IMMEDIATE, and SAFE."

Maritime tracking and industry reports indicate only sporadic vessel movements after the ceasefire announcement, with oil and gas tankers largely avoiding transits amid lingering security and insurance concerns. Some ship-tracking services recorded isolated crossings but overall volumes are a fraction of peacetime levels, leaving barrels in backlog and supply chains under strain.

White House economic adviser Kevin Hassett sought to downplay the immediate macroeconomic impact in television interviews, noting that tankers were "starting to dribble through" and arguing for a short-lived disruption; nevertheless, market analysts warn that even a single tanker incident can sharply affect insurance rates and spot premiums, meaning that limited passage does not equal normalised flows.

Financial markets reacted quickly to the ceasefire news with a relief rally and falling futures, yet the physical market remains tight: while headline prices dropped, cargo- and grade-specific premia persisted as refiners and traders priced in logistical bottlenecks and the time required to move product from the Gulf to consuming centres. Traders and brokers note that full normalization will depend on durable security guarantees and insurer willingness to underwrite Gulf transits.

In a broader geopolitical and economic context, restoring reliable passage through Hormuz affects not only crude flows but also LNG, refined products and global inflation dynamics; market participants say the outlook hinges on the ceasefire's durability and the operational details of reopening — whether phased, escorted, or conditional — so volatility is likely to remain elevated until sustained, verifiable traffic resumes.
