Demand Driven by Artificial Intelligence

The reshaping of semiconductor supply chains is no longer a matter of foresight. It shows up in customs statistics. In September, South Korea's exports surged 83.5% year-on-year to reach ?.9 billion. That is an absolute monthly record, shattering the previous peak of ?.25 billion set in June. The engine behind this surge is identified: explosive demand for chips to power artificial intelligence infrastructure.

This figure goes beyond a simple cyclical performance. It shows that computing power has become a strategic asset whose production remains concentrated in a small number of countries. It also shows that major consuming economies are seeking to reduce that dependence. The gap of nearly ? billion between the June and September records reflects an acceleration, not a plateau. Buyers are securing their volumes in a market where supply struggles to keep pace.

Seoul, Supplier and Investor

South Korea thus occupies a paradoxical position. It is one of the major beneficiaries of the AI wave as an exporter. It is also engaged in a partial relocation of its capital toward its main strategic partner. US President Donald Trump announced a plan providing for ? billion in South Korean investments in projects located in the United States. It is the first set of major projects under a broader framework.

This linkage illustrates the current logic of reshoring. Producing countries no longer simply ship components. They are required to invest on the soil of destination markets to retain their access. Trade flows are now accompanied by investment flows, and the two have become inseparable in bilateral negotiations.

Energy, the Hidden Input of Industrial Sovereignty

The first tranche of this program is telling. Of the ? billion announced, ? billion is earmarked for Alaska LNG, a long-considered liquefied natural gas project. It envisions a 1,300-kilometer pipeline connecting North Slope reserves to the southern coast of Alaska, from which the gas would be exported. The project was announced on October 1, 2026. Seoul, the main investor, nonetheless conditions its commitment on commercial viability that remains to be demonstrated.

The link to semiconductors is not incidental. Chip manufacturing and the operation of the data centers that use them are among the most energy-intensive industrial activities. Securing a gas supply means securing the upstream end of the entire electronics chain. Industrial reshoring therefore creates demand for components, but also for all the physical resources needed to produce them. That includes energy, metals, and the critical minerals essential to manufacturing processes.

Europe Confronts the Cost of Energy

The European counterexample sheds light on what is at stake. European Union steel exports are absorbing a triple shock: high energy costs, tariffs, and Chinese overcapacity flooding markets. This diagnosis extends beyond steelmaking. Any European ambition to reshore semiconductor production will run into the same structural constraints: expensive energy, a hostile tariff environment, and Chinese competition capable of crushing prices.

Meanwhile, in Brussels, major technology companies are deploying intense lobbying. The regulatory battle over digital technology is playing out in parallel with the industrial battle. Europe remains a major consumer market, but its ability to influence the upstream end of the value chain remains limited.

Southeast Asia, the New Hub of Assembly

Reshoring is not limited to bringing operations back to Western countries. It also takes the form of geographic diversification within Asia. Germany's Infineon Technologies invested 48 billion baht, or ?.44 billion, to expand its assembly and packaging capacity in Thailand. The group sees the potential to eventually produce semiconductors in the country.

The timeline, however, remains cautious. Alexander Gorski, Infineon's chief operations officer, indicated in Bangkok that this expansion could be a first step toward wafer fabrication. He judged such a leap unlikely within the next three years. Thailand is highlighting its position as an Asian logistics platform, a decisive advantage for an industry whose components cross numerous borders before reaching the finished product.

A Gradual Move Up the Value Chain

Infineon's strategy illustrates the classic pattern of industrial regionalization. It starts with the least capital- and technology-intensive stages: assembly and testing. Wafer fabrication, the most demanding segment in terms of capital, expertise, and resources, is considered next. Each stage completed increases local demand for specialized inputs, including critical minerals and industrial gases. It also redraws the supply routes for those materials.

Flows That Are Fragmenting and Densifying

These dynamics converge on one conclusion: the global semiconductor map is fragmenting even as it densifies. Flows of finished products remain massive, as the South Korean record shows. But they are accompanied by a multiplication of intermediate production hubs, both in the United States and in Southeast Asia. Each of these hubs will need to be supplied with raw materials, energy, and components.

For critical minerals, this dispersion changes the equation. A concentrated chain allowed for short, optimized logistics routes. A fragmented chain multiplies demand points and therefore the need for safety stocks. It also increases exposure to trade tensions. The tariffs already penalizing European steel demonstrate the vulnerability of any sector dependent on inputs subject to tariff barriers.

Points to Watch

Three signals warrant close monitoring. The first is the sustainability of AI-related demand: a growth rate of 83.5% year-on-year cannot continue indefinitely, and any slowdown would ripple through the entire chain. The second is the effective conversion of investment commitments into actual capacity. Seoul already subordinates its participation in the Alaska gas project to its commercial profitability. The third is the ability of new hubs, such as Thailand, to cross the threshold of wafer fabrication, which alone durably anchors an industry in a territory.

The reshoring of semiconductors is a structural movement, but its concrete translation will be slow and costly. It will depend more on access to energy and resources than on political announcements.
