China imports more oil than any other nation on earth. A majority of that oil originates in the Persian Gulf. The overwhelming majority of that Gulf oil moves through the Strait of Hormuz. This dependency is the most significant structural vulnerability in the Chinese economy, and Beijing has spent the better part of two decades trying to reduce it without succeeding in any meaningful way.

The arithmetic is unforgiving. China’s oil import dependence has risen, not fallen, as its economy has grown. Domestic production has plateaued and is declining at the margin. The non-Gulf sources that Beijing has cultivated — Russia, Angola, Brazil — are real but insufficient to replace Gulf supply. When analysts calculate what a thirty-day closure of Hormuz would do to Chinese industrial output, the numbers become politically significant very quickly. Beijing’s strategic planners know this. They treat it as the central energy security problem that has no clean solution.

India sits at the northwestern edge of the Indian Ocean, closer to the Persian Gulf than any other major Asian economy except China. This geography is an asset — shorter transit times, lower shipping costs, access to Gulf labor markets that have sustained remittance flows for decades — and a vulnerability. The same proximity that makes Indian trade with the Gulf efficient makes Indian energy security exposure to Hormuz direct and consequential.

The energy transition is real. Its timeline is contested. Its implication for the Strait of Hormuz over the coming decades is one of the more genuinely uncertain strategic questions in global energy analysis — not because the direction is unclear, but because the pace will determine whether the transition reduces Hormuz’s leverage before or after the next major crisis that tests it.

The optimistic scenario runs as follows. Electric vehicle adoption reduces oil demand in transportation, which is the largest end-use sector for petroleum. Renewables displace natural gas in power generation. Industrial electrification reduces demand in heavy industry. Global oil demand peaks sometime in the 2020s or early 2030s and declines steadily thereafter. As the total volume of oil that must transit Hormuz falls, so does the economic damage that any given closure would impose, and so does the strategic leverage that Iran extracts from its position on the northern jaw of the strait.
