Strait of Hormuz Turmoil and Helium Shortage: Dual Challenges for Global Supply Chain Volatility

Abstract

The Strait of Hormuz, a vital chokepoint for global energy and critical resource transport, saw a continuous decline in traffic, sparking deep concerns about supply chain stability. Meanwhile, China's Ministry of Commerce announced a temporary ban on helium exports to address severe shortages of semiconductor raw material. This article will deeply analyze the intrinsic link between the two events, from dimensions of geopolitical risk, resource supply chain vulnerability, and semiconductor industry strategic security, revealing deep contradictions in the global economy under extreme uncertainty, and exploring countermeasures.

Introduction

In spring 2024, two troubling news items came out in the global market: first, the traffic volume through the Strait of Hormuz significantly declined for two consecutive days; second, China's Ministry of Commerce urgently imposed a temporary ban on helium exports. On the surface, these two events belong to different domains - the former concerns energy transport channel security, the latter involves semiconductor raw material supply. However, in-depth analysis reveals they both point to the fragile nature of supply chains in the globalized era and the intensifying struggle for control of critical resources under the background of major power games. Shipping fluctuations in the Strait of Hormuz affect not only traditional energy like oil and liquefied natural gas but also the global circulation of rare industrial gases like helium, which is indispensable for semiconductor manufacturing. When the "chokepoint" of the supply chain is tightened, governments have to resort to extraordinary measures. China's temporary helium export control is a vivid example of this logic.

I. Strait of Hormuz: The “Achilles' Heel” of Global Energy and Resource Transport

1.1 Waterway Safety Under Geopolitical Game

The Strait of Hormuz lies between the Persian Gulf and the Gulf of Oman, with its narrowest point only about 33 kilometers, yet it handles about 20% of global oil shipments and about 30% of liquefied natural gas trade. More importantly, nearly a quarter of global helium production is transported through this strait, as major helium producers such as Qatar and Saudi Arabia are located along the Persian Gulf. The recent consecutive decline in traffic is due to complex reasons: military confrontation between Iran and Israel continues to escalate, Houthi attacks on Red Sea merchant vessels have affected alternative routes to the Strait of Hormuz, and the US-Iran nuclear negotiations are deadlocked, causing insurance costs for passing ships to soar, extended sailing times, and even direct obstruction.

1.2 Ripple Effects of Declining Traffic

The decline in traffic is not an isolated phenomenon but a signal of concentrated release of global geopolitical risks. According to the International Shipping Association, in the past month alone, the number of crude oil tankers passing through the Strait of Hormuz decreased by about 15%, and LNG carriers decreased by about 8%. This change has directly pushed up energy import costs for Asian countries, with natural gas spot prices in Japan, South Korea, and India rising by about 12%. A more dangerous consequence: if strait passage is obstructed for a long time, the global economy would face a serious recession risk - the IEA has calculated that a 30-day closure of the Strait of Hormuz would cost the global GDP over $300 billion.

II. Helium: The “Invisible Lifeline” of Semiconductor Manufacturing

2.1 The Critical Role of Helium in the Semiconductor Supply Chain

Helium, with its extremely low boiling point (-268.9°C) and chemical inertness, plays an irreplaceable role in semiconductor manufacturing. In the lithography step, helium is used to cool the mirrors and wafer stages of extreme ultraviolet lithography (EUV) machines. In etching and deposition processes, high-purity helium is used as a carrier gas and protective gas. In packaging and testing, liquid helium is essential for low-temperature testing equipment. The industry estimates that each 12-inch wafer consumes about 500 liters of helium. With explosive growth in demand for 5G chips, AI computing chips, and advanced memory, global helium consumption is growing at 3%-5% annually, while supply growth is constrained by geological conditions and technical barriers.

2.2 Deep Reasons for Shortage

The current helium shortage is due to multiple factors: the US, as the world's largest helium producer, sees its Federal Helium Reserve (BLM) system output declining due to aging equipment and management issues; Qatar's three large helium plants are expanding capacity, but export uncertainty is high due to Strait of Hormuz transport risks; Russia's helium projects (such as the Amur Gas Processing Plant) have failed to reach production due to Western sanctions and logistics bottlenecks. More critically, China, as one of the world's largest semiconductor production bases, accounts for about 18% of global helium demand, while domestic self-sufficiency is less than 5% - meaning China's dependence on imported helium is extremely high, and any supply chain disruption could directly impact the normal production of chip manufacturers.

III. Policy Logic of China's Ministry of Commerce Temporary Export Ban

3.1 Urgent Background of the Policy

In April 2024, China's Ministry of Commerce announced a temporary ban on helium exports, forbidding unlicensed exports of helium and related equipment. This decision, on the surface an emergency measure to "prevent shortage of semiconductor manufacturing raw materials," is actually a strategic arrangement in response to the risk of global supply chain disruption. Due to the decline in Strait of Hormuz traffic delaying arrival of helium from Qatar and other regions and driving up prices, helium inventories of major domestic semiconductor companies have fallen below warning levels. According to industry calculations, if supply interruption lasts one month, China's leading foundries may face production cuts of 15%-20%. In this context, restricting exports to prioritize stable domestic production became a logical choice.

3.2 Multiple Strategic Considerations of the Policy

The temporary export ban is not simple trade protection but contains far-reaching strategic considerations: first, to prevent overseas demand from excessively squeezing domestic supply and avoid domestic market imbalance caused by "price hikes and panic buying"; second, to force the domestic helium industry chain to become self-reliant, including accelerating commercialization of helium recovery technology, encouraging private capital investment in helium exploration and liquefaction projects; third, as a negotiating chip to counter export controls from some countries on Chinese semiconductor equipment. It is noteworthy that the policy has a "temporary" nature, retaining room for dynamic adjustment, showing that the Chinese government has not given up efforts to solve problems through international cooperation.

IV. Crisis Linkage: Transmission Chain from Strait of Hormuz to Semiconductor Factories

4.1 “Butterfly Effect” of Supply Chain

The link between the Strait of Hormuz shipping crisis and helium export controls constitutes a typical global supply chain chain reaction case. When strait shipping is blocked, helium traders are forced to reroute around the Cape of Good Hope or Suez Canal, adding 10-15 days to shipping time and raising freight costs by over 30%. These costs are ultimately passed on to semiconductor manufacturers, who, to keep production lines running, have to bid for spot helium at high prices. In this process, Chinese semiconductor companies, with high import dependence and relatively weak bargaining power, suffer the most severe impact. Therefore, the Ministry of Commerce chose to temporarily close the export valve, keeping limited resources at home - a "domestic circulation" strategy that can alleviate the short-term crisis but also reveals the erosion of trust among nations under the global division of labor system.

4.2 From Energy to Technology: New Battleground of Great Power Games

At a deeper level, these two events jointly reveal a core feature of the current international order: supply chains of critical resources have become strategic weapons in geopolitical games. The turmoil in the Strait of Hormuz is behind the US-Iran confrontation and power vacuum in the Middle East; the helium supply crisis reflects the hidden effects of US tech decoupling from China - although the US has not directly restricted helium exports, the alliance system it leads has already disrupted global helium trade flows. China's temporary export controls are essentially a "firewall" measure against this systemic risk. However, building a firewall itself increases market fragmentation, further raising operating costs for global semiconductor manufacturing.

V. Conclusion and Outlook

The decline in Strait of Hormuz traffic and China's temporary helium export restrictions appear isolated but are mutually causal and reinforcing. In the foreseeable future, similar dual crises will occur more frequently - as long as the global energy and resource system relies on a few fragile chokepoints, and supply chains of strategic industries like semiconductors are highly concentrated among a few suppliers, we will have to face the risk of "black swan" events evolving into "gray rhino" norms.

The solution lies in coordination of multiple paths: first, the international community should increase efforts to maintain freedom of navigation, especially ensuring safe passage through the Strait of Hormuz, to prevent geopolitical conflicts from spilling over into global supply crises. Second, countries need to accelerate diversified deployment of critical resources, such as developing extraction technology for helium associated with shale gas, promoting helium recovery and recycling systems, and exploring alternative cooling media like liquid hydrogen. Third, for the semiconductor industry, establishing strategic reserve systems (including helium, high-purity gases, specialty chemicals, etc.) is urgent. China's temporary export controls are both a stopgap measure and should become a catalyst for promoting self-sufficiency in the domestic helium industry.

Globalization has not ended, but it is undergoing a painful transformation. When the tides of the Strait of Hormuz and the cleanrooms of semiconductor factories become unavoidably linked, we truly realize how delicate the balance upon which the precision operation of modern civilization is built. Only with greater wisdom and a spirit of cooperation can we steadily walk the tightrope of this supply chain.
