The current conflict in the Middle East has pushed the global energy market into turmoil. Although a fragile ceasefire persists between Iran and the United States, uncertainty around navigation through the Strait of Hormuz remains a central concern. Iran has resumed attacks targeting commercial vessels transiting through the waterway, in a sharp reversal from its April 17 statement that claimed that the strait is “completely open.” Additionally, the unspecified number of sea mines deployed in the waterway and the parallel U.S. naval blockade have further made commercial passage nearly impossible. 

Iran’s weaponization of the Strait of Hormuz during wartime has exposed critical vulnerabilities in global energy supply chains, demonstrating how even brief disruptions can ripple rapidly across the world. The uncertainty premium does not seem to be going away anytime soon. The broader warning is that the world, still dangerously exposed to a single fragile bottleneck, can no longer treat energy diversification, strategic storage, and secure shipping arrangements as long-term goals. 

This risk is especially acute for Asia, where heavy reliance on Gulf energy imports makes the region the first and most immediate casualty of any disruption, amplifying its role as the primary conduit through which local conflicts translate into global economic instability.

The World’s Chicken Neck

The Strait of Hormuz looks small on the map, but it is one of the few places where geography still has the power to shock the entire global economy. That is why “the world’s chicken neck” is a useful way to describe it – a narrow corridor through which an outsized share of global energy flows. According to the U.S. Energy Information Administration, flows through the strait in 2024 and early 2025 accounted for more than one-quarter of global seaborne oil trade, about one-fifth of global oil and petroleum product consumption, and around one-fifth of global liquefied natural gas (LNG) trade. Weaponizing such an important channel as a bargaining chip can be understood as testing a “nuclear weapon,” albeit one that operates through disruption, not destruction.

Since the beginning of the present conflict, ship transit through Hormuz dropped from around 130 a day in February to just six in March, a collapse of about 95 percent. The speed of this disruption shows how quickly local conflicts can trigger global shocks. Markets respond not only to events, but to risk, with oil and gas prices reacting almost in real time. Brent crude crossed $90 on March 6 and peaked at $112 on March 20 before oscillating between $100 and $110 through late March and early April. It has since stabilized around $90-$95.

These swings reflect more than actual shortages; they capture the pricing of uncertainty. Sea mines, gunfire, shifting military signals, volatile insurance, and shipping hesitancy are all factored in. The Strait of Hormuz has effectively become a geopolitical risk premium with a shipping lane attached to it.

Disruption Is Most Consequential for Asia 

The spillover does not stop with gasoline. Higher energy, bunker fuel, freight, and insurance costs are already contributing to fertilizer, food, and broader cost-of-living pressures. For Asia, which consumes more energy relative to its GDP than any other continent, the disruption is more immediate and consequential. In 2024, more than 80 percent of crude oil and LNG transiting through Hormuz was destined for Asian markets, with China, India, Japan, and South Korea accounting for the bulk of demand. This concentration means that any disruption in the Gulf does not remain just a supply issue. It quickly becomes a demand shock as Asian economies compete for cargoes, pushing prices higher across global markets.

Within Asia, China, as the world’s largest crude importer, faces a dual challenge. China possesses strategic reserves and diversified suppliers, yet remains heavily reliant on Gulf producers such as Saudi Arabia, Iraq, and Iran. This creates a paradox where China is both more resilient in the short term and more exposed over the long term. The disruption of Hormuz adds a second layer to Beijing’s longstanding concern over maritime chokepoints. 

For Japan and South Korea, the risk is more immediate and less buffered. Both economies import roughly 80-90 percent of their crude oil from the Middle East and rely heavily on LNG for power generation. With limited domestic resources and constrained storage flexibility, their exposure is not about strategic maneuvering like China but about managing price shocks and supply continuity in real time. Even short-lived disruptions translate into higher import bills, currency pressures, and downstream industrial costs. 

India sits somewhere in between. Its dependence on imported oil and gas – combined with a still coal-heavy energy mix – makes it particularly sensitive to price volatility. As of January, about 55 percent of India’s crude imports came from the Middle East, and current refinery inventories covered only a limited number of days, regardless of national storage capacity. Moreover, with almost half of India’s crude oil and liquefied petroleum gas (LPG) supplies passing through the strait, it faces a direct transmission channel from geopolitical risk to domestic inflation and, ultimately, to macroeconomic challenges such as stagflation. 

Beyond the major economies, Southeast Asia represents a secondary but important shock zone. Singapore’s role as a global refining and trading hub means that disruptions in shipping flows and pricing reverberate through its financial and logistical systems. Meanwhile, net importers such as Indonesia and Thailand face renewed pressure on fuel subsidies and external balances, as higher energy costs strain fiscal positions and complicate monetary policy. These economies may not drive global demand, but they are highly sensitive to fluctuations in it.

The broader implication is that Asia is not merely exposed to disruptions in Hormuz; it is the primary transmission mechanism through which those disruptions shape global outcomes. Asia effectively sets the marginal price for oil and gas during periods of stress. When supply tightens, it is Asian demand that pushes prices upward, transmitting shocks to the rest of the world.

The Way Forward

A ceasefire will not solve this problem in the absence of a comprehensive political solution. Even if a solution were to arise quickly and all sides were to respect the agreement at hand, the threat of neutralizing the sea mines spread across the strait remains paramount. Although the United States has begun conducting mine-sweeping operations, the U.S. Navy claims that the traffic separation scheme is “not fully understood,” which should be enough for companies to avoid the area. The reality is that reopening the strait is a traffic-management, mine-clearance, insurance, and confidence-restoration problem all at once. One cannot flip a switch and declare normal commerce restored with just a post on social media.

Four steps must be undertaken to restore pre-war normalcy and establish norms for any contingencies in the future. First, the priority must be de-escalation, as there is no durable shipping solution without a political one. The onus is upon the United States and Iran to reach a comprehensive agreement, not merely a ceasefire, which would eliminate the threat of kinetic actions in the region that could once again risk global shipping routes. Such an agreement must be U.N.-mandated, with no actor being able to shut critical trade routes unanimously – especially Iran, which has no legal mandate as per international law to claim the strait. 

Second, a future agreement must encompass an emergency safe-passage arrangement under U.N. and the International Maritime Organization (IMO) backing, built on the existing traffic separation scheme, with neutral technical monitoring and explicit protections for merchant shipping. The IMO has already argued that freedom of navigation is non-negotiable and stated that it is developing an evacuation and safe-passage framework. 

Third, major energy-consuming countries should coordinate stock releases and demand restraint. The International Energy Agency (IEA) has already shown that this is possible. In early March, IEA members agreed to the largest coordinated oil-stock release in the agency’s history, drawing on emergency reserves that exceed 1.2 billion barrels. 

Fourth, energy import-dependent countries – especially in Asia – should treat energy diversification and strategic storage not as long-term aspirations but as urgent national security tasks.

The world cannot keep pretending that a system this concentrated is resilient. The Strait of Hormuz is not just a shipping lane; it is a stress test for the way energy, trade, and security are wired together. Every new crisis in the Gulf now functions as a tax on the rest of the world. The lesson is not only that wars spill over. It is that the global economy still rests on chokepoints that are far too narrow for the stakes they carry.
