If a strait closes: five scenarios (crude oil, all countries on file)
Illustrative arithmetic on stated assumptions; not a forecast; not advice. It does not say whether, when or for how long a strait will close. Late is never added to lost.
- Strait of Hormuz closed for 30 days: stopped 930–933 mb; arrives late 67–68 mb; lost 651–673 mb Hormuz crude figures count flows with a named buyer: 11.9 of 19.9 mb/d (approved Hormuz export).
- Strait of Hormuz closed for 90 days: stopped 1 641–1 644 mb; arrives late 67 mb; lost 1 227–1 249 mb Hormuz crude figures count flows with a named buyer: 11.9 of 19.9 mb/d (approved Hormuz export).
- Hormuz and Bab el-Mandeb closed together for 90 days: stopped 1 653–1 656 mb; arrives late 274–290 mb; lost 1 227–1 249 mb Hormuz crude figures count flows with a named buyer: 11.9 of 19.9 mb/d (approved Hormuz export).
- Bab el-Mandeb avoided by half of traffic for 90 days: stopped 58 mb; arrives late 58 mb; lost 0 mb
- Strait of Malacca closed for 14 days: stopped 159 mb; arrives late 159 mb; lost 0 mb
