In a new report, the US government’s Energy Information Administration (EIA) has identified seven major chokepoints for the worldwide maritime transit of oil, which accounted for about 61% of global petroleum and other liquids production movements in 2015 (when total world supply was about 96.7m b/d). The Strait of Hormuz in the Gulf and the Strait of Malacca, which links the Indian and Pacific oceans, are the most important strategic chokepoints by volume of oil transit.
