Three Months After the Hormuz Shutdown: A Global Supply Chain in Crisis

The LPG Market: Stranded Supply and Canceled Cargoes

The immediate impact on the liquefied petroleum gas (LPG) market has been severe. The International Energy Agency (IEA) identified LPG as the oil product most affected by the disruption . In 2025, roughly 30% of global seaborne LPG exports transited the Strait of Hormuz . With the strait closed, approximately 1.5 million barrels per day of Middle Eastern supply was effectively stranded .

This shock instantly tightened global balances. Asian buyers, who absorbed 97% of outbound Middle Eastern flows before the crisis, were forced to scramble for alternatives, dramatically increasing demand for US Gulf Coast cargoes . This shift, however, has been chaotic. US LPG shipments to Asia were canceled outright as the war triggered a massive surge in freight rates, forcing buyers to break contracts . Even the US export surge has been constrained; analysts at Jefferies noted that existing export capacity on the US Gulf Coast was already at its maximum, limiting the system's ability to compensate for the stranded Middle Eastern barrels . By mid-May 2026, global seaborne LPG exports had partially recovered to around 4.8 million barrels per day, but remained significantly below pre-crisis records due to these logistical bottlenecks .

Japan's Energy Shock: A "Structural Crisis"

No country better illustrates the domino effect of the Hormuz closure than Japan. The world's fourth-largest economy depends on the Middle East for roughly 94% of its crude oil, with about 90% of that supply transiting the strait . The result has been what analysts are calling a "structural crisis" .

• In March 2026, Japan's crude imports fell 17% year-on-year, marking the lowest volume since 1989. Imports from Qatar collapsed by 81%, while Kuwait's shipments dropped by 64% .
• By May, Japan was on track to secure only about 60% of its crude through alternative procurement routes that bypass the strait, according to the Japanese Prime Minister's office, a figure that underscores the sheer difficulty of rewiring long-established energy supply chains .
• The nation has also drawn down a record 80 million barrels from its strategic petroleum reserves in response to the crisis .

A Desperate Diplomatic Pivot

The supply shock has forced Tokyo to make two extraordinary and previously unthinkable energy deals.

• First-Ever US Crude: In late April 2026, Japan took its first-ever shipment of crude oil from the United States, a cargo that arrived amid the crisis as a direct alternative to stranded Gulf supplies .
• Return of Russian Oil: In a more geopolitically stunning move, Japan received its first shipment of Russian oil since the start of the war in Ukraine in early May. A tanker carrying crude from the Sakhalin-2 project offloaded its cargo at a refinery in western Japan, effectively shattering the post-Ukraine unity among G7 nations on energy sanctions .

This pivot highlights the brutal trade-offs forced by the crisis: economic survival trumps diplomatic solidarity. The return of Russian oil to Japanese ports is a concrete example of how the Hormuz closure is rapidly redrawing geopolitical alliances, a scenario the Atlantic Council warned would help Beijing and Moscow while hurting American interests .

Qatar's LNG: An Unprecedented Market in Turmoil

The crisis has struck at the heart of Qatar's economy. The Ras Laffan Industrial City, the nexus of the nation's world-leading LNG production, was directly disrupted . This, combined with the inability to transit the strait, has plunged the global LNG market into what international law firm DLA Piper described as "unprecedented territory," triggering a wave of contractual disputes as sellers cannot deliver and buyers cannot receive cargoes .

What began as a supply shock has evolved into a transit disruption, with the physical movement of LNG being the most acute challenge . With a large share of its LNG output effectively trapped, the fiscal pressure on Qatar's state budget is immense, though specific deficit projections are not yet publicly available. The crisis underscores the vulnerability of nations whose entire economic model rests on a single maritime passage.

The Food Chain: Fertilizer Supply in "Convulsion"

The disruption’s reach extends deep into the global food supply. The Atlantic Council has warned that the closure could send "convulsions" through supply chains for fertilizers, which are foundational to global agriculture . Before the crisis, the Gulf supplied roughly 23% of global ammonia demand and a third of global fertilizer shipments .

• Production Halts: Iran, a major producer of urea and ammonia, is cut off from export markets. Gulf-based fertilizer production that relies on Iranian gas feedstocks has also been impacted .
• Price Cascades: The broader energy shock has driven up global natural gas prices—the primary input for ammonia-based fertilizers—leading to a cascade of higher costs throughout the food production system .

A detailed analysis by Disrupt-SC identified Africa's fertilizer supply as one of the most vulnerable non-oil supply chains in this entire crisis, warning of severe consequences for food security on the continent .

The Aftershock: Why the Worst May Be Yet to Come

Institutional warnings paint a bleak picture for the months ahead. The most alarming insight comes from a detailed supply chain analysis by Disrupt-SC, which found that the economic damage from a Hormuz closure is highly nonlinear. Inventories absorb the initial shock, but approximately 90% of the cumulative consumption losses from a prolonged closure occur after the strait reopens, as protracted shortages, price volatility, and logistical chaos cascade through the real economy .

A late May 2026 analysis from Arizona State University’s Thunderbird School warned bluntly that “the worst may be yet to come,” noting that rising oil prices and transshipment disruptions are already destabilizing the global economy . The Atlantic Council has been equally stark, stating that every additional day of closure brings the world economy "closer to crisis" .

The Strait of Hormuz crisis is not simply an energy story; it is a rolling shockwave that has exposed the extreme fragility of just-in-time global supply chains. As countries are forced into zero-sum competition for scarce alternatives—from US LPG to Russian crude—the diplomatic and economic foundations of the post-Cold War world are being reshaped in real time.
