Fujairah sits on the Gulf of Oman coast of the United Arab Emirates, on the far side of the Hajar Mountains from Dubai and Abu Dhabi. For most of its history it was the smallest and least developed of the seven emirates, with a fishing economy and a geography that made connection to the Emirati interior difficult. What transformed Fujairah was the recognition, by Abu Dhabi planners and international oil traders simultaneously, that a port on the Gulf of Oman side of the UAE was worth more than a port on the Arabian Gulf side because it lay outside the Strait of Hormuz. Its strategic value is a function of what it avoids.

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 strategic logic of Iran’s Hormuz threat rests on the assumption that the cost of closure to the outside world exceeds the cost of closure to Iran. This assumption is correct in relative terms and misleading in absolute terms. Iran would suffer severely from a Hormuz closure that it initiated. Its oil exports, its import supply chain, and its remaining international financial connections all depend on the strait remaining open. The question is whether the political leadership in Tehran would initiate a closure despite these costs, and under what conditions the answer would be yes. The Iranian domestic economy is the ledger that answers that question.

Iraq is the second-largest producer in OPEC and the country most completely helpless in a Hormuz closure scenario. Nearly all of its oil exports — the revenue that funds approximately 90 percent of the government’s budget — move through terminals near Basra in the far south of the country, load onto tankers in the northern Gulf, and transit the strait to reach their buyers. Iraq has no bypass pipeline capacity of consequence, no alternative export route, and no political influence over the parties whose conflict would cause the closure. It is a bystander to its own financial ruin.

Israel does not import oil through the Strait of Hormuz. Its energy supply arrives primarily through the Ashkelon terminal from the Caspian pipeline system and through domestic production from offshore Mediterranean fields that have grown substantially over the past fifteen years. Israel’s direct exposure to Hormuz transit is limited. Its indirect exposure — through the price effects of any closure, through the regional security consequences of US-Iran conflict, and through the impact of Iranian military capacity on the deterrence calculus that Israel maintains — is substantial and persistent.

Japan imports approximately 90 percent of its energy. It has no significant domestic fossil fuel production. Its nuclear power sector, which once provided a substantial share of electricity generation, has been operating at sharply reduced capacity since the Fukushima accident of 2011, with only a portion of the pre-accident reactor fleet returned to service. The Gulf supplies the majority of Japan’s crude oil, and Gulf LNG — primarily from Qatar — supplies a substantial portion of its natural gas. There is no combination of alternative energy policies or supply source diversification that changes the fundamental arithmetic on the timescale of months. Japan’s dependence on Hormuz is existential in a way that is not hyperbole.

Kuwait remembers. Of all the Gulf states whose oil revenues depend on Hormuz transit, Kuwait is the one with the most direct experience of what it looks like when a regional power decides that its neighbors’ sovereignty and economic interests are subordinate to its own strategic ambitions. The Iraqi invasion of August 1990 and the seven-month occupation that followed were not a Hormuz closure, but they were something equivalent in economic and political terms: the abrupt elimination of Kuwait’s ability to govern itself and export its oil. The institutional memory of that period shapes Kuwaiti foreign policy in ways that are distinct from the other Gulf states that have not experienced occupation.

The Musandam Peninsula is an exclave of Oman separated from the rest of the sultanate by a strip of UAE territory. It juts northward into the Gulf, forming the southern jaw of the Strait of Hormuz. Iran’s coastline forms the northern jaw. Between them is the corridor through which the global oil trade flows. Oman is the only country in the world that shares a maritime border with Iran along the strait, and this geographic fact has given the sultanate a diplomatic role that its size and military capacity would not otherwise justify.

Pakistan sits at the northeastern corner of the Arabian Sea, flanked by Iran to its west and with a coastline that extends from the Gulf of Oman toward India. It is the world’s only nuclear-armed Muslim-majority state, a country with deep financial and demographic ties to the Gulf Arab states, and a country with a 900-kilometer land border with Iran. Its position makes it relevant to every major regional security scenario, including Hormuz, without giving it decisive influence over any of them. Pakistan is courted and pressured simultaneously by parties whose interests in the Gulf are incompatible, and it manages this position with a hedging strategy that satisfies no one and infuriates everyone.

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.
