**Summary**: Fresh data show Strait of Hormuz crude exports have dropped to about 9 million bpd from 17 million bpd in early October, following multiple IRGC‑linked mine incidents on supertankers. This confirms an operational supply shock, not just a risk premium, and points to sustained upside pressure on crude benchmarks and freight, with growing contagion risk to LNG and refined products.

## Detail

UBS Evidence Lab data now indicate that crude oil outflows through the Strait of Hormuz have fallen to roughly 9 million barrels per day, down from about 17 million bpd in early October. This coincides with confirmed IRGC Navy statements that at least two supertankers carrying >2 million barrels each struck naval mines and caught fire while allegedly using “unauthorized routes” with transponders disabled. Previous headlines framed this mainly as a shipping security event; the new figure quantifies a realized flow disruption of roughly 8 million bpd, around 8% of global oil supply.

In the very near term, some of this loss may reflect temporary rerouting, shipholding, and insurer‑driven pauses rather than physical production shut‑ins. However, even if only half of the 8 mb/d is materially delayed (days to weeks), prompt crude availability tightens sharply. Asian refiners most reliant on Gulf grades (Saudi, Iraqi, Emirati, Kuwaiti, and Iranian flows) face delivery uncertainty and higher premiums, pushing them to bid up alternative Atlantic Basin and West African barrels and draw down inventories.

Historically, the 2019–2020 Gulf tanker incidents and the 1980s “Tanker War” added several dollars per barrel of risk premium with far smaller measured flow losses. A move from 17 to 9 mb/d is multiple orders more severe in volumetric terms, even if partly transient, and should support a multi‑dollar upside in Brent and Dubai benchmarks, sharply higher Gulf–Asia VLCC freight, and widening Dubai/Brent spreads. LNG and product tankers transiting nearby lanes will also see higher war‑risk premia and potential delays, lifting Asian spot LNG and regional refined product cracks.

If mines and security tensions persist for weeks, producers may be forced to curtail output or accumulate onshore storage near capacity, elevating the probability of OPEC+ emergency coordination and/or Western naval escorts. Market reaction is likely to reflect both immediate supply tightness and a structurally higher probability that a future incident could close Hormuz more completely. The impact should be considered high and potentially enduring so long as verified flows remain well below pre‑October levels.
