Strait of Hormuz
high riskThe only sea exit from the Persian Gulf. Pipelines around it carry only part of its oil: the Saudi East-West line to Yanbu about 5 million barrels a day of crude for export (7 million in total, 2 million of which feed Saudi refineries) and ADCOP to Fujairah 1.5 million.
Answer
About 20.9 million barrels of crude and fuels pass through here every day – ~20% of global oil consumption, or 10 supertankers a day. The map shows 10.6 million of that in crude oil routes. The countries most dependent on the Strait of Hormuz are South Korea (58% of imports), Japan (49% of imports), China (41% of imports) and India (38% of imports).
