Technopolitik: Circuit-Breakers for Tech?
— By Arindam Goswami
When the Dutch government used a Cold War-era emergency law to take control of Nexperia, a Chinese-owned semiconductor maker, in October 2025, it revealed something uncomfortable about the approaches to technology governance. Operating without circuit breakers at all is dangerous. Here was a company producing unglamorous but critical automotive chips - the kind that control your airbags and power steering - that had been Chinese-owned since 2018. Seven years passed before The Hague noticed its CEO was allegedly preparing to transfer European intellectual property and production capabilities to China. Seven years of increasing dependence, deepening integration, and mounting vulnerability before anyone thought to check if the safety mechanisms actually worked.
Circuit-Breaker Metaphor
The circuit-breaker metaphor matters because it reframes how we think about tech sovereignty. Physical circuit breakers don’t prevent electricity from flowing; they prevent catastrophic failures by interrupting current when safe thresholds are breached. Similarly, what governments need isn’t blanket protectionism but intelligent intervention mechanisms that activate at predetermined stress points - before foreign acquisitions become fait accompli, before supply chains become irreversibly dependent, before national capabilities evaporate overnight.
China already operates with this principle, though few have articulated it this way. When Beijing reviews mergers and acquisitions through its State Administration for Market Regulation (SAMR), it isn’t simply checking for competition concerns. SAMR must, by law, consider transactions’ impact on “national economic development” - a deliberately expansive mandate that allows regulators to consult government ministries, industry associations, and state-owned enterprises before approving deals. In recent years, SAMR has imposed conditions on semiconductor deals involving quite a few companies, forcing them to agree to continued supply at “reasonable prices” to Chinese customers. These were circuit breakers designed to prevent strategic technologies from becoming geopolitical weapons.
This isn’t just protectionism, but an integration of economic and security considerations. SAMR coordinates with the National Development and Reform Commission on national security reviews, creating overlapping jurisdictions that catch transactions other systems might miss. As more and more deals have involved critical infrastructure and key technologies, circuit breakers have been tripped on a number of occasions. The system is deliberately redundant, recognising that in the strategic industries, false negatives-missing a dangerous transaction-are far costlier than false positives-unnecessarily delaying a benign one.
Three-Tiered Framework
What is needed is a three-tiered model for technology evaluation that learns from both China’s integrated approach and the Nexperia failure’s hard lessons. The first tier would assess strategic criticality. Does the technology sit at a genuine chokepoint in critical supply chains? Nexperia controlled roughly five percent of the global automotive silicon discrete market - small enough to seem inconsequential, large enough to halt production lines across Europe when China retaliated with export restrictions. The evaluation here isn’t about current market share but about substitutability and concentration risk. If losing access would take years to remedy through alternative suppliers or domestic production, it’s strategically critical.
The second tier examines knowledge trajectory. Where is the capability moving, and can it return? This addresses the Nexperia problem directly - the concern wasn’t just Chinese ownership but the planned migration of know-how and production capacity to mainland China. Once certain types of manufacturing expertise and tacit knowledge leave, they don’t simply bounce back. Germany learned this with solar panels, America with consumer electronics. A good heuristic: if rebuilding the capability would require training a new generation of engineers and workers, it’s probably a one-way door.
The third tier weighs temporal reversibility. Can intervention be delayed without permanent consequence? The Netherlands learned that to wait seven years transformed what could have been a manageable ownership review into an emergency that required unprecedented legal measures. By the time The Hague acted, Nexperia’s operations were so integrated with Chinese parent company Wingtech that decoupling required court-appointed custodians and suspension of the Chinese CEO - exactly the kind of dramatic intervention that erodes investor confidence and complicates diplomatic relations. Earlier circuit breakers would have created options; delay eliminated them.
This three-tiered approach illuminates which chokepoints genuinely matter. Not every semiconductor company requires scrutiny, but those producing automotive-grade chips that take five years to qualify with automakers and involve concentrated manufacturing capacity probably do. Not every software acquisition threatens national security, but platforms controlling critical infrastructure authentication systems or industrial control networks warrant careful review. The framework helps governments distinguish between technologies that are merely advanced (interesting but substitutable) and those that are foundational (critical and concentrated).
Four Questions
It requires a cost-benefit analysis that moves beyond blind references to national security. Any policy intervention should answer four questions. First, what is the measurable risk? Quantify the economic cost of supply disruption, the time required to develop alternative sources, and the likelihood of interruption given current geopolitical trends. The European automotive sector’s potential exposure to Nexperia supply cuts is measurable in billions of euros and months of lost production - that’s a concrete risk assessment, not speculation.
Second, what are the intervention costs? There are direct costs, such as paying for government oversight and funding alternative development, and indirect costs, including disincentivising legitimate investment, complicating international relations, and letting go of efficiency gains from integration. The Dutch government’s Nexperia intervention carries real costs: strained relations with China, potential retaliation against other Dutch companies, legal expenses, and the precedent of executive power overriding property rights. These costs deserve honest accounting.
Third, what alternatives exist? Before activating emergency circuit breakers, have you tried better monitoring, conditional approvals with enforcement mechanisms, or incentives for domestic alternatives? Many SAMR conditional clearances, whatever their motivations, demonstrate that surgical behavioural remedies can address concerns without blocking transactions entirely. A commitment to maintain European R&D centres and production capacity might have addressed Nexperia concerns without requiring governmental seizure.
Fourth, what’s the opportunity cost of inaction? This is where most cost-benefit analyses fail, underweighting low-probability, high-consequence risks because they haven’t materialised yet. The Netherlands’ seven-year delay meant the eventual intervention was far more costly and disruptive than early action would have been.
A cost-benefit framework weighing such interventions should make early and proportionate action preferable to late and dramatic measures. A screening mechanism blocking problematic acquisitions before they close leaves more options than emergency seizures after seven years of Chinese ownership. Conditional approvals that mandate continued local operations and knowledge retention work better than trying to reverse completed technology transfers. The goal isn’t autarky - that’s economically ruinous and technologically impossible - but rather maintaining the ability to sustain critical functions even under stress.
Find legitimate chokepoints through the three-tier model; judge interventions candidly with the cost-benefit framework. Design circuit breakers that trip early enough to preserve options but not so sensitively that they disrupt every transaction. The goal is resilience without rigidity, security without isolation.
The Nexperia case won’t be the last crisis of tech sovereignty, but it should inform how to handle the next ones. Circuit breakers in electrical systems do not wait for catastrophic failures but act on predictable thresholds. They preserve the system by preventing disaster. Technology governance needs the same wisdom: clear thresholds, early interventions, and mechanisms that protect without paralysis. The question is not whether to build circuit breakers into technology governance systems. After Nexperia, it’s why they haven’t been built yet.
