Saudi Arabia's way round Hormuz ends on the Red Sea. If the Red Sea's southern strait closes too, that route is delayed or lost.
In short Closing Bab el-Mandeb as well adds delay, not loss: Saudi crude sent round Africa arrives 27-36 days late. Illustrative arithmetic on stated assumptions; not a forecast; not advice.

What this means
Approved reading
Goods beyond crude
The second closure changes crude most. For the other goods, the Hormuz closure already stops them.
Prices: what published studies found
Published studyObserved 2026
Others' estimates for a comparable disruption, and what Brent actually did. Strature computes no price. Each figure is one dated, named estimate.
Two fact-checked published figures exist for both straits at once, both from spring 2026: Brent toward USD 140 (Bloomberg Economics, one source) and about USD 20 a barrel added (J.P. Morgan). Brent went from a July average of USD 84 to a September average of USD 114 (EIA), while both straits were disrupted and other drivers overlapped; that move is not the effect of one event. The ranges are the publishers', not Strature estimates.
Insurance: observed war-risk premiums
Observed
Quoted additional war-risk premiums per transit, as a share of the ship's hull value, as published. Each bar is one dated press-reported quote. No forecast.
It has happened: the 2026 record
Observed
The closest analogue is this year. Dates as reported; the scenario borrows none of them as a prediction.
Second order: Europe's fuel through India and South Korea
modelled links
Europe buys refined fuel from refiners that run on Gulf crude. Cited links only.
