The 36,000 square kilometer weak point of the global economy – Why the global chip supply hangs by a single thread

The $1.6 trillion risk: Why the global race for microchips is in danger of failing

Barely larger than Baden-Württemberg, yet the undisputed center of gravity of the modern world: Taiwan has become the biggest vulnerability of the global economy. Whether smartphones, electric cars, or the rapid development of artificial intelligence – without the highly complex semiconductors from the island's factories, technological progress worldwide would grind to a halt. But this unprecedented monopoly carries an extreme risk. Faced with China's undisguised power ambitions and the threat of blockades, the US and Europe are desperately trying to rebuild chip production domestically with multi-billion-dollar megafactories. An in-depth analysis reveals that this geopolitical and technological disentanglement is a dramatic race against time – and the outcome for the global economy is more than uncertain.

The biggest weakness of the global economy: What happens when China's chip trap snaps shut?

There are few places on the world map whose strategic importance oscillates so drastically between economic reality and geopolitical threat as Taiwan. The island, barely larger than the German state of Baden-Württemberg, has become a crucial hub for global technology supply. Anyone who wants to understand why security advisors in Washington hold confidential meetings with executives from Apple, AMD, and Qualcomm and warn of a Chinese blockade must know the figures that make Taiwan an indispensable node in digital civilization.

Taiwan produces over 60 percent of all semiconductors worldwide and controls approximately 92 percent of the global manufacturing capacity for advanced logic chips with feature sizes of ten nanometers or less. This concentration is not the result of chance, but of decades of strategic investment, technological excellence, and an ecosystem whose density and performance cannot be replicated anywhere else in the world.

TSMC – The gravitational center of the semiconductor world

At the heart of this concentration is the Taiwan Semiconductor Manufacturing Company, better known as TSMC. In the second quarter of 2025, the company controlled a 70.2 percent share of the global pure-play foundry market, an all-time high, having risen from 53.4 percent in the second quarter of 2022. Samsung, its next largest competitor, holds around eight percent. Intel lags even further behind. TSMC's dominance is not just a matter of market share, but of technological leadership. When it comes to the most advanced manufacturing processes required to produce AI accelerators, smartphone processors, and high-performance chips, TSMC has no real rival.

TSMC's customer list reads like a who's who of the technology industry. Nvidia has its GPU designs manufactured there. Apple sources its M-series processors from TSMC. AMD, Qualcomm, Broadcom, and virtually every other leading chip designer relies on the factories in Taiwan. Even the companies building the infrastructure for artificial intelligence, whether Google, Amazon Web Services, Meta, or Microsoft, depend directly or indirectly on TSMC. This dependence extends across the entire value chain of the digital economy and encompasses industries ranging from automotive and medical technology to defense.

An island as a single point of failure

The strategic vulnerability resulting from this concentration cannot be overstated. Taiwan's entire IC industry reached a production value of $165 billion in 2024, a 22 percent increase over the previous year. The semiconductor sector accounts for roughly 40 percent of total Taiwanese exports. Taiwan's chips are found in every modern smartphone, every data center, every electric vehicle, and every military system in the Western world. A disruption of this production, whether due to a natural disaster, a military confrontation, or an economic blockade, would have consequences extending far beyond the technology sector.

The RAND Corporation succinctly summarized the situation: If China were to invade Taiwan, either the chip factories could fall under Chinese control or be destroyed in the course of a conflict. Both scenarios would be devastating for the global economy. Taiwan's semiconductor industry could lose an estimated $1.6 trillion in annual revenue in the event of an invasion, while downstream industries in technology, consumer electronics, and automotive would experience massive delays and price explosions.

China's ambitions and the Taiwan question

Beijing has regarded Taiwan as a renegade province for decades and has never relinquished its claim to reunification. Military activity in the vicinity of the Taiwan Strait has intensified in recent years. Scientific analyses using scenario studies and tabletop exercises conclude that a quarantine scenario—a partial sea and air blockade of Taiwan—is the most likely form of escalation before 2027, as it offers low mobilization costs combined with high disruptive potential.

Such a quarantine would expose Taiwan's greatest structural weakness: its near-total dependence on energy imports. In 2021, the island obtained approximately 97.7 percent of its total energy from fossil fuel imports. Its reserves were sufficient for about 39 days of coal, 146 days of oil, and only 11 days of natural gas. An effective naval blockade could bring the energy supply, and thus chip production, to a standstill within a matter of weeks.

The bitter irony of this situation lies in the mutual dependence. China itself imports around 60 percent of its chips from Taiwan, with Taiwanese semiconductor exports to mainland China and Hong Kong totaling $85 billion in 2024. An invasion would therefore also massively damage China's own economy. Nevertheless, there is growing concern that China's increasing technological isolation due to Western sanctions is increasing the incentive for an aggressive solution to the Taiwan question: the more China is cut off from advanced chips, the greater the strategic value of direct control over the island becomes.

The Huawei incident as a warning signal

The Huawei incident dramatically demonstrated how porous the existing control mechanisms are. A report by the Center for Strategic and International Studies revealed that Huawei had procured more than two million Ascend 910B AI chips from TSMC through shell companies, even though the Chinese company has been on the US sanctions list since 2020 and should not have access to products based on American technology.

The mechanism was insidious in its simplicity. Huawei forwarded its chip designs to the company Sophgo, which then placed orders with TSMC as its own designs. TSMC manufactured the chips unaware of the scheme until the company became suspicious when Sophgo placed orders for a chip that bore a striking resemblance to the Huawei Ascend 910B. TSMC reported the incident to US authorities. The consequences were significant: The US Department of Commerce launched an investigation that could result in a fine of one billion dollars or more for TSMC.

Taiwan responded with stricter export controls. The island nation banned the export of chips and chiplets to Huawei and SMIC and introduced new licensing requirements for all transactions with these companies. The distinction between conventional chips and chiplets—modular semiconductor components that can combine various specialized components—proved crucial. Huawei had deliberately exploited the chiplet architecture to circumvent the existing restrictions.

The diversification strategy and its limits

The realization that such a concentrated dependence is unsustainable has triggered a global diversification movement. Over the past two years, TSMC has received approximately $4.7 billion in subsidies from the governments of the United States, Japan, Germany, and China to geographically spread its manufacturing operations.

The most ambitious project is the expansion in Arizona, into which TSMC is investing a total of $165 billion. The plan includes six factories, two packaging facilities for advanced chips, and a research center. The first factory in Arizona began mass production using the N4 process in the fourth quarter of 2024, achieving a remarkable yield of 92 percent, surpassing even the results of comparable facilities in Taiwan. Construction of the second factory for the 3-nanometer process is complete, and mass production has been brought forward to the second half of 2027, several quarters earlier than originally planned. A third factory for the 2-nanometer process is under construction, and a fourth is in the permitting phase.

In Japan, the first specialized factory in Kumamoto began mass production at the end of 2024, and a second is under construction. In Dresden, Germany, construction of a factory for specialized technologies is progressing, with the start of production dependent on market demand.

Nevertheless, diversification alone will not solve the core problem, at least not within the strategically relevant timeframe. Even if all planned factories come online on schedule, only about 30 percent of TSMC's capacity for 2-nanometer and more advanced processes is expected to be located in Arizona. The vast majority of global production will remain on the island. Furthermore, costs in the US are about 50 percent higher than originally estimated, and the shortage of skilled workers has already caused delays.

The price of dependency in numbers

The economic costs of a conflict over Taiwan would be incalculable. Economies dependent on semiconductor-related value chains, including China, the US, Japan, Germany, and large parts of Southeast Asia, would experience declining production levels and a potential economic downturn. Sea and air freight routes through the Taiwan Strait and the South and East China Seas could be disrupted during a conflict, causing logistics costs to skyrocket worldwide.

A full-scale attack on Taiwan would plunge the world into a severe economic crisis, as global trade sanctions and reputational risks would effectively force multinational corporations to withdraw from China, potentially jeopardizing trade flows worth around three trillion dollars. The worst-case scenario of open conflict would have repercussions that would virtually paralyze global trade.

The core geopolitical question of the 21st century

The Taiwan question has long since evolved from a regional issue to one of the central geopolitical challenges of the 21st century. It is no longer primarily a technological issue, but rather a question of how the global economic order is organized in an era where the most important resource of digital civilization is produced on an island claimed by the world's most powerful authoritarian state.

Short-term options are limited. A complete diversification of chip production is not realistic within the next five to ten years. Costs are too high, the necessary talent is too scarce, and the required infrastructure is too complex. What remains is a strategy of risk reduction through gradual diversification, combined with diplomatic and military deterrent measures. The factories in Arizona, Japan, and Dresden are investments in a ten-year hedge, not for tomorrow's threats.

The dynamics of the situation are further exacerbated by the fact that the AI ​​revolution is massively increasing the demand for advanced chips. TSMC expects accelerated production of its 2-nanometer machines in 2026 due to strong demand, although rising depreciation costs are likely to reduce the gross margin by two to three percentage points. The more important these chips become to the economy, the higher the geopolitical stakes will be. The world is in a race between technological diversification and geopolitical escalation, and it is by no means certain that diversification will win this race.
