Hormuz Shipping Craters to 10 % of Normal as US Renews Blockade and Iran Shuts Strait

Chokepoints have long been pressure points in Gulf geopolitics: during the 1984-88 “Tanker War” the US re-flagged Kuwaiti tankers to keep Hormuz open, and in 1956 Nasser’s closure of the Suez Canal forced a rerouting of 10 % of world oil, reshaping global logistics for a decade. Today’s plunge in Hormuz traffic fits a century-long pattern of energy arteries becoming theatres of power projection. The renewed blockade underscores two trends: 1) the US–Iran rivalry has migrated from centrifuges to sea lanes, giving Tehran leverage without breaching the NPT, and 2) Gulf exporters are fast-tracking overland pipes and Red Sea ports, gradually diluting Hormuz’s monopoly much as the SUMED pipeline lessened dependence on Suez after 1973. Over a 100-year horizon, this moment may mark the start of Hormuz’s decline from indispensable chokepoint to one of several contested routes, illustrating how energy transition, alternative corridors, and drone-enabled littoral warfare can redefine maritime geography even before oil itself is eclipsed.
