Iraq and Syria signed a cooperation agreement on July 17 to rehabilitate and reconstruct the Kirkuk-Baniyas crude oil pipeline, a Mediterranean export route that has sat dormant for decades. The signing took place in Washington on the sidelines of a US-Iraq business summit, during Iraqi Prime Minister Ali al-Zaidi’s visit to the United States, which also included a stop in Houston for meetings with major energy firms.

Basra Oil Company CEO Bassam Abdul Karim Nasr signed on behalf of Iraq, and Syrian Petroleum Company CEO Yousef Kabali signed for Syria. US Energy Secretary Chris Wright attended the ceremony, and the State Department framed the pipeline as a strategic infrastructure project to be executed by a US-led international consortium.

The headline number is 20% on all cargo shipped through the Strait of Hormuz, framed as reimbursement for American protection. The legal objections write themselves and have already been written. The more interesting question is who the levy actually lands on, and the answer is not Iran.

It lands on Qatar.

The Only Cargo That Cannot Escape

Around 93% of Qatar’s LNG exports and 96% of the UAE’s leave through the Strait of Hormuz. There is no alternative route. Crude has partial escapes — Saudi Arabia and the UAE hold somewhere between 3.5 and 5.5 million barrels a day of pipeline bypass capacity, enough to matter at the margin. Gas has none. You cannot put liquefied natural gas on a truck, and no pipeline exists that can move Ras Laffan’s output to a non-Gulf loading point at any volume worth discussing. Qatari LNG goes through the strait or it does not go.

The February blockade of the Strait of Hormuz left a lasting impression on Washington, and the response now taking shape is not a short-term fix but a structural one. Tehran’s decision to shut the chokepoint at the outset of the joint U.S./Israeli operation sent oil prices spiking more than 70 percent almost overnight, a shock severe enough that the prospect of the blockade dragging into the November midterms became a central factor pushing Trump toward a ceasefire. Having lived through that scenario once, the U.S. and its allies are now working to make sure Iran’s most potent card loses most of its value.

Secretary of State Marco Rubio recently put it bluntly: the Strait of Hormuz is “basically the equivalent of an economic nuclear weapon that Iran is trying to use against the world.” He wasn’t being hyperbolic. He was being precise.

Iran has spent years bragging about its ability to choke the strait — the narrow waterway through which roughly 20 percent of the world’s traded oil passes. Every tanker carrying Saudi, Emirati, Kuwaiti, or Iraqi crude to Asia and Europe transits those 21 miles. Iran sits on one shore. The threat is structural, permanent, and deliberate.

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.

Before February 2022, European energy security analysis treated the Persian Gulf as a significant but secondary concern. The primary vulnerabilities ran through Ukrainian pipeline corridors and Russian supply decisions. Hormuz was a risk to Asian energy markets, to oil prices globally, and to a residual flow of LNG from Qatar to a handful of European regasification terminals that had been built for flexibility rather than baseload supply. The invasion of Ukraine changed this with a speed that European energy planners had not fully modeled. By the end of 2022, Europe was competing in global LNG markets for volumes that included substantial Qatari supply, and its exposure to events in the Persian Gulf had become structurally different from anything its policy frameworks had anticipated.

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.

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.

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.

The price of oil is not a single number. It is a cluster of interconnected prices — benchmark crudes, differentials, futures curves, physical cargo assessments — that reflect supply and demand conditions, transportation costs, refinery preferences, and risk. The Hormuz risk premium is one component of this price structure, and tracking how it enters and exits the price complex reveals something important about how markets price geopolitical threats that are real but uncertain.

The shale revolution changed American domestic energy politics in ways that altered the public rhetoric around Middle East engagement without fundamentally altering the strategic logic for maintaining it. The United States produced more oil than any other country on earth for several consecutive years before 2026. It became a net petroleum exporter. American politicians of both parties used these facts to argue that the country’s commitments in the Gulf were relics of a dependency that no longer existed. The argument is politically compelling and strategically incomplete.

South Korea is among the most energy-import-dependent economies of any significant size in the world. It has no domestic oil production, minimal natural gas reserves, and a geography that makes pipeline connections to alternative supply sources impossible. Its entire hydrocarbon supply arrives by sea, a majority of it from the Persian Gulf, and all of the Gulf portion transits the Strait of Hormuz. The country has built one of the world’s largest economies and most sophisticated industrial sectors on an energy supply foundation that is concentrated in a single maritime corridor controlled in part by a government that has expressed willingness to disrupt it.

Global oil markets operate with a margin of production capacity that is not currently being used. This spare capacity — oil wells that are drilled and capable of producing but are held back to manage price levels within OPEC+ target ranges — is the primary buffer that the market can deploy in response to supply disruptions. The overwhelming majority of it sits in the Gulf. In the event of a Hormuz closure, that spare capacity would be simultaneously the most valuable resource in global energy markets and the one most completely inaccessible, because the wells that hold it are connected to export terminals that require the strait to reach their buyers.

The Strait of Hormuz has never been closed. The threat of closure has been used repeatedly as a diplomatic instrument by Iran, and incidents in the strait have periodically elevated insurance premiums, rerouted tankers, and spiked oil prices. What has not happened, in the modern era of global oil dependence, is a complete cessation of transit. This absence of precedent does not mean the scenario is implausible. It means that the consequences of closure must be modeled rather than observed, and the models are sobering.

Beneath the shallow waters of the Gulf, shared between Qatar and Iran, lies the North Field — the largest single natural gas reservoir on earth. The Qatari portion is developed. The Iranian portion, called South Pars, is partially developed and severely constrained by sanctions and investment restrictions. What happens to the gas that Qatar extracts from its side of the reservoir determines energy supply conditions for electricity consumers in Japan, industrial gas buyers in South Korea, and power generators across Europe. All of it moves through Hormuz.
