The Strait of Hormuz was once treated as the site of a hypothetical catastrophe: a narrow waterway whose closure could send shock waves through the global economy. In 2026, the confrontation involving Iran, the United States, and Israel turned that warning into an expensive reality. The question now is not whether turmoil in Hormuz can damage energy markets, but how much more damage another escalation could inflict.

The costs stretch well beyond the Persian Gulf. Asian importers depend heavily on Gulf oil and gas; European businesses face higher fuel bills; Gulf producers risk losing export revenue. Meanwhile, Azerbaijan and Turkey have become more strategically important because their energy routes bypass Hormuz. But greater strategic relevance should not be confused with the ability to replace Gulf supplies.

Before the disruption, roughly 20 million barrels of crude oil and petroleum products moved through Hormuz daily, equivalent to about one-fifth of global oil consumption. The strait was also a major outlet for liquefied natural gas, particularly from Qatar. Saudi Arabian and Emirati pipelines offer some alternatives, but cannot accommodate all the traffic that ordinarily passes through the waterway.

The danger is not limited to crude oil. In October, the International Energy Agency accelerated previously pledged emergency stock releases, including plans to bring more than 20 million barrels of diesel to market. Even when crude is available, refineries, tankers, and transport networks may be unable to supply the right fuel to the right place. Strategic reserves can ease a shortage; they cannot indefinitely replace a functioning energy system.

Three plausible paths now confront the region. None offers a painless return to normality. The difference between them matters: a partial reopening would leave lingering risk, an extended standoff could quietly weaken economies, and direct attacks on energy infrastructure could magnify the damage far beyond the shipping lanes.

The first is a fragile reopening. Negotiations involving Iran, Washington, and regional intermediaries could establish limited safeguards for commercial shipping without settling the larger conflict. Iran would continue to seek security and economic concessions, while the United States would insist on protecting commerce and its regional partners. Both would have incentives to avoid an open-ended energy emergency.

Yet an agreement on paper would not immediately restore confidence at sea. Shipowners would need assurances, insurers would recalculate risks, and damaged infrastructure would require repairs. Tankers might return before freight rates and insurance premiums normalized. A reopening would likely be uneven, with the threat of renewed confrontation still reflected in prices. For governments eager to declare victory, that distinction would be politically inconvenient. A ship passing safely through the strait is encouraging; a dependable system requires hundreds of vessels to make the journey repeatedly without an extraordinary military escort or prohibitive insurance charges.

The second path is a prolonged disruption without a wider war. Neither side escalates decisively, but neither secures a deal that makes shipping reliably safe. Intermittent attacks, expensive insurance, and uncertain schedules become the new normal. For the global economy, this could be more corrosive than a brief, dramatic closure.

China’s diversified suppliers offer some protection, but not immunity for an economy of its size. India would absorb higher import costs, while Japan and South Korea would face persistent energy-security pressures. Europe’s exposure differs, but it cannot escape global markets: Asian competition for cargoes raises prices elsewhere, and costly diesel undermines transport, manufacturing, and household budgets. Over time, higher energy costs reshape investment, inflation expectations, and industrial competitiveness. If instability extends into 2027, the damage could accumulate into slower growth and greater political pressure. Emergency subsidies might shield consumers temporarily, but they would shift costs onto public budgets.

Businesses making decisions about factories, freight contracts, and hiring cannot plan around assurances that the crisis may end soon. Uncertainty itself becomes an economic tax.

The third, most dangerous path is a wider regional escalation. Strikes against refineries, ports, storage sites, or export terminals could turn a shipping crisis into an infrastructure crisis. Saudi Arabia, Qatar, and the United Arab Emirates would face stronger pressure to defend energy facilities; Washington could expand naval deployments and air defenses. But military protection cannot guarantee that dispersed, vulnerable facilities will keep operating. The scale of the economic shock would depend less on a dramatic headline oil-price forecast than on which assets were hit, how long repairs took, and whether alternative routes remained usable.

These scenarios explain why attention is shifting toward the Caspian basin. Azerbaijan exports oil through the Baku–Tbilisi–Ceyhan pipeline and sends natural gas west through the Southern Gas Corridor, which links the South Caucasus Pipeline with the Trans-Anatolian and Trans-Adriatic pipelines. These routes connect Azerbaijan with Turkey and European customers without relying on the Persian Gulf. Azerbaijani gas deliveries also reached buyers in Germany and Austria in 2026, underscoring Baku’s expanding European role.

There are limits, however. Geography can reduce dependence on one chokepoint, but it cannot conjure new molecules of gas or barrels of crude. Production capacity, existing contracts, pipeline constraints, and the cost of new investment prevent Azerbaijan from becoming an emergency replacement for Gulf exports. Its opportunity is more realistic, and potentially more durable: to become a valued additional supplier in an energy market increasingly concerned with reliability as well as price.

Turkey occupies a similarly complicated position. Its infrastructure and location connect Caspian producers with European consumers, while its relationship with Azerbaijan strengthens both countries’ place in Europe’s diversification plans. Ankara’s diplomatic reach and security capabilities add to its influence. Yet Turkey is also a major energy importer. The very crisis that raises its transit value can raise costs for Turkish businesses and households. Strategic leverage is not economic immunity.

Europe, meanwhile, can release reserves, coordinate fuel supplies, and reduce demand in the short term. Over the longer term, additional Caspian gas requires investment in production and pipelines, financing, and buyers willing to make durable commitments. Governments cannot declare new capacity into existence. Infrastructure that improves resilience will take years, not weeks, to develop. That delay creates a political dilemma: policymakers need relief now, while the investments that could make a future crisis less destructive may not deliver visible benefits until long after today’s emergency has faded.

The overlooked casualty of a drawn-out Hormuz crisis may be confidence. Buyers need to trust that contracted energy will arrive; shipping firms must believe their crews and vessels are safe; investors must expect facilities to operate for decades. Even if traffic increases, unpredictable attacks and elevated security costs can keep markets unsettled.

That leaves no tidy roster of winners and losers. Gulf states risk revenues and infrastructure; Asian importers face supply insecurity; Europe faces inflation and industrial strain. The United States benefits from domestic production but still pays global energy prices and bears security costs. Azerbaijan and Turkey gain influence, but remain exposed to wider economic fallout.

Hormuz has exposed a stubborn truth about the global energy system: possessing oil and gas is not enough. What increasingly matters is the ability to deliver them dependably when vital routes become dangerous. The next escalation may begin in a narrow stretch of water, but the bill will arrive across the world.
