**Gulf Supply Shocks Could Hit Euro Area Growth, Warns ECB**
The European Central Bank (ECB) has issued a warning regarding the potential impact of trade disruptions through the Strait of Hormuz on the euro area economy. In a recent blog post, ECB economists Pablo Aguilar, Lukas Boeckelmann, and Antoine Kornprobst highlighted that supply shortages could extend beyond rising energy prices, potentially threatening up to 3 percent of euro area production in a worst-case scenario.
The Strait of Hormuz, a crucial passage for global energy supplies, has been at the center of geopolitical tensions, particularly in the Middle East. Although recent conflicts have eased, the ECB stresses that the region remains a critical bottleneck for energy exports. The economists noted that the ongoing war in the Middle East and the subsequent disruptions have already unsettled oil markets, leading to significant increases in energy prices and heightened uncertainty across the global economy.
The ECB's analysis points to the risk of supply shortages in energy, petrochemicals, and other intermediate goods originating from Gulf countries. If importing nations are unable to replace these vital supplies—due to depleted inventories or unavailability of strategic reserves—production processes could be severely hampered. This would not only weaken economic growth but also exacerbate inflationary pressures.
In their assessment, the ECB acknowledged that the Eurosystem staff had already factored in the effects of elevated global energy prices into the ECB’s severe Middle East scenario for its June 2026 macroeconomic projections. However, the latest analysis delves deeper into the additional risks posed by physical supply shortages and fragmented trade flows.
The degree of dependence on Gulf energy imports varies significantly across different economies. Asian nations are identified as the most vulnerable, with Gulf suppliers accounting for over 50 percent of total energy imports in Japan, South Korea, and India, while China and ASEAN countries rely on Gulf energy for approximately one-third of their imports. In contrast, the euro area, the United Kingdom, and the United States depend on Gulf energy for only about 10 percent of their total energy imports.
The ECB also highlighted that energy-intensive industries—such as petrochemicals, aluminium, fertilizers, and semiconductors—are particularly susceptible to supply disruptions. Problems in these sectors could ripple through global manufacturing, especially since Asia plays a pivotal role in the international production landscape. A decline in industrial output in Asia could have extensive repercussions worldwide.
While the risks associated with disruptions to non-energy goods from Gulf countries appear relatively limited, the ECB cautioned that shortages in products like fertilizers, aluminium, and petrochemicals could still have significant downstream effects. Their analysis estimated that disruptions could lead to a reduction of around one-third in global helium production and one-fifth in global methanol production, impacting key industries such as semiconductors and aerospace.
The ECB evaluated two scenarios: one involving a complete and sustained disruption to Gulf energy exports, and another extending this disruption to industrial and other goods. The first scenario assumed that domestic buffers, including strategic oil and gas reserves, would not be available to mitigate supply shortages for households and businesses. The second scenario illustrated the limited capacity of firms to replace disrupted imports, highlighting the vulnerabilities within international supply chains.
Using two distinct economic models, the ECB found that the most significant production losses would occur in Asia, with projections indicating a potential decline of up to 11 percent in South Korea, around 8 percent in India, approximately 7 percent in Japan, and up to 5 percent across ASEAN economies. For the euro area, production losses could reach up to 3 percent if firms are unable to find alternatives for disrupted supplies. However, in a more favorable scenario where businesses successfully substitute missing imports, euro area production losses would be considerably lower—0.4 percent under the energy disruption scenario and 0.6 percent under the broader disruption scenario.
The ECB concluded that scenario analysis is a vital tool for evaluating geopolitical risks that extend beyond mere increases in energy prices and uncertainty. Although the probability of such severe disruptions has decreased with the easing of regional tensions, persistent interruptions in energy and intermediate goods supplies could significantly heighten the economic costs of geopolitical shocks through global production networks.
The authors emphasized the importance of monitoring both direct energy dependence and indirect supply chain vulnerabilities. They called for maintaining adequate strategic buffers and enhancing contingency planning for sectors that rely on critical inputs that are challenging to replace, underscoring the need for proactive measures in the face of potential supply shocks.
