This Is What the US Just Did to China on Semiconductors

Episode Summary

Executive Summary: The episode centers on Chris Miller’s book Chip War and the Biden administration’s sweeping new semiconductor export controls on China. The discussion frames semiconductors as a strategic chokepoint shaped by decades of U.S. policy, COVID-era shortages, and the CHIPS Act’s push to strengthen domestic capacity. The core message: advanced chip supply chains are highly concentrated, hard to replicate, and now central to U.S.-China geopolitical competition.

Main Topics: Chip War and the timing of policy changes (Priority: 5/5): The hosts introduce Chris Miller’s new book and note the striking coincidence that it released just as the Biden administration unveiled major new China chip export restrictions. History of semiconductor export controls (Priority: 5/5): Miller explains that controls on chip technology have existed since the Cold War, originally aimed at the Soviet Union, and that today’s China-focused controls are an extension of longstanding national security logic. What the new Biden controls change (Priority: 5/5): The new rules broaden restrictions beyond the most advanced tools to include older-generation equipment, AI GPUs, supercomputer-related chips, and U.S. persons working with Chinese chip firms. Why semiconductors are strategically different from oil (Priority: 4/5): The conversation compares chips to oil but stresses that chipmaking is even more concentrated at the leading edge and embedded in globally interdependent supply chains. COVID shortages and political attention (Priority: 4/5): The pandemic exposed how dependent the global economy is on chips, though Miller argues the real issue was uneven allocation and automaker procurement mistakes more than a true chip shortage. China’s response and long-term catch-up prospects (Priority: 5/5): Miller argues China has limited retaliation options and that catching up in advanced semiconductors will be extremely difficult, expensive, and time-consuming due to the complexity of the ecosystem. CHIPS Act, U.S. industrial policy, and Taiwan risk (Priority: 5/5): The episode discusses the CHIPS Act as both a manufacturing subsidy package and an insurance policy against Taiwan disruption, while acknowledging tensions with allies like Taiwan and South Korea.

Key Arguments: Semiconductor export controls are not a new invention; they are a continuation of Cold War-era efforts to limit militarily relevant technology transfer. The Biden administration’s latest rules are broader and more aggressive than prior U.S. restrictions, especially because they target older-node equipment, AI chips, and U.S. persons. The global chip supply chain is highly concentrated, with Taiwan dominating advanced processor output and ASML controlling EUV lithography at the leading edge. COVID did not cause a true collapse in chip supply; rather, demand rose faster than supply, and automakers mismanaged procurement. China’s best short-term response is likely rhetorical rather than retaliatory because meaningful retaliation could hurt China more than the U.S. China can attempt to catch up technologically, but doing so would require large spending, long timelines, and close collaboration that current restrictions are designed to disrupt. The CHIPS Act is best understood as an insurance policy against geopolitical disruption, not a path to complete U.S. self-sufficiency. U.S. policy toward semiconductors is part of a broader effort to pull advanced production and ecosystem capacity toward the U.S. and away from China.

Data Points: Book release date: October 4, 2022 - Chris Miller’s Chip War was described as having been released just before the export-control announcement. Export-control announcement date: October 7, 2022 - The Biden administration’s new semiconductor restrictions were announced only days after the book came out. Share of chips used for civilian purposes: 98% or so - Miller noted that unlike the Cold War, most chips today are used for civilian applications. Taiwan’s share of global processor chips: Over one-third - Used to illustrate concentration of chip manufacturing compared with oil production. Taiwan’s share of the most advanced processor chips: 90% - Cited as evidence of extreme concentration at the cutting edge. EUV lithography at the leading edge: 100% controlled by ASML - Miller highlighted ASML’s monopoly-like position at the most advanced lithography node. U.S. share of chip production: 10% to 15% - Current U.S. share of global chip manufacturing, used to show that the CHIPS Act will not make the U.S. self-sufficient. CHIPS Act manufacturing subsidies: $39 billion - Funds allocated to chip manufacturing in the U.S. CHIPS Act R&D funding: $12 billion - Funds allocated to semiconductor research and development. China’s chipmaking threshold in new rules: 16 nanometers or below - The new rules restrict equipment going to facilities at or below this node for logic chips. COVID-era chip supply behavior: Aggregate supply increased dramatically in 2020 and 2021 - Miller argued production rose even during the pandemic while demand rose faster. Potential EU chip subsidy package: 50 billion euros - Miller referenced Europe’s intended spending on chips policy.

Pivotal Quotes: "I think the trajectory was pretty clear from the last time we spoke about two years ago that we're going to see more tightening of controls and more bifurcation between the U.S. and China developing separate semiconductor ecosystems." — Chris Miller: Explaining why the new export restrictions were part of a longer-running policy trend.

"I think this actually has the chance to have a really substantial impact over the coming decade." — Chris Miller: On the CHIPS Act’s R&D funding and its likely long-run importance.

Implications: Listeners should take away that semiconductors are now a core geopolitical battleground. The new controls may slow China’s progress, accelerate supply-chain realignment, and deepen U.S.-China tech bifurcation, while making chip resilience and domestic capacity a major policy priority.
