US-D-05: The CHIPS Act and the Inflation Reduction Act: Industrial Policy Revival and Green Transition (2022–2025)

1. Key Takeaways

• The CHIPS and Science Act (signed 9 August 2022) represented the most significant explicit industrial policy legislation enacted by the US federal government since the post-World War II era. The law authorised $52.7 billion in direct semiconductor manufacturing incentives and $200 billion in science and R&D investment over ten years. Its passage, with Senate approval 64–33 and House approval 243–187, reflected an unusual bipartisan consensus built on national security framing: COVID-era chip shortages had paralysed US automobile production, and the concentration of leading-edge semiconductor fabrication in Taiwan — a site of potential military conflict with China — was deemed a strategic vulnerability requiring direct government intervention.

• The Inflation Reduction Act (signed 16 August 2022) was the largest climate investment in US history, allocating approximately $369 billion to climate and clean energy over ten years within a broader $737 billion revenue-and-spending package. The IRA achieved legislative passage only after a series of near-deaths: the original Build Back Better framework had been publicly killed by Senator Joe Manchin in December 2021. The Schumer-Manchin framework announced 27 July 2022 resurrected a truncated but historically meaningful package, trading away much of the social spending in BBB for durable clean energy tax credits, drug pricing reform, and deficit reduction through corporate taxation.

• Together, CHIPS and IRA constituted a structural break with the post-1980 Washington Consensus on trade and industrial policy. National Security Advisor Jake Sullivan's April 2023 speech at the Brookings Institution explicitly named this departure: the US was abandoning "trickle-down economics" and the assumption that markets alone would allocate resources optimally for national security. Sullivan described a "new Washington consensus" based on resilient supply chains, strategic public investment, and a "worker-centred trade policy" — a deliberate response to the empirical research of Autor, Dorn, and Hanson documenting the labour market devastation caused by rapid import competition.

• The CHIPS Act's guardrails were as consequential as its grants. Recipients of CHIPS Manufacturing Incentive grants were prohibited from expanding leading-edge chip manufacturing capacity in "countries of concern" (China, Russia, Iran, North Korea) for ten years. This provision effectively forced semiconductor companies — including TSMC, Samsung, SK Hynix, and Intel — to choose between US subsidy and expanded China operations. The guardrails reflected a bipartisan congressional view that semiconductor supply chain decoupling from China was a strategic imperative, not merely an economic option.

• The IRA's domestic-content requirements became a major transatlantic trade dispute. Electric vehicle tax credits ($7,500 for new EVs) required final assembly in North America and a rising percentage of battery minerals sourced from the US or countries with US free trade agreements. European automakers and governments protested that these requirements violated WTO commitments and discriminated against EU-made EVs. The Biden administration negotiated "critical minerals agreements" with the EU, Japan, and South Korea that were designed to qualify their supply chains for IRA benefits — a creative use of executive trade agreements to share IRA's industrial policy benefits with allies without requiring Senate-ratified treaties.

• CHIPS investment announcements exceeded initial expectations in scale, but execution encountered significant delays. TSMC announced a $40 billion investment in two Arizona fabs (Phoenix), later expanded to a $65 billion three-fab cluster after a Biden visit in late 2024. Intel announced $20 billion in Ohio fabs (New Albany) and further international investments. Samsung committed $17 billion to a Taylor, Texas facility. Micron Technology announced $40 billion in US memory chip investment across New York and Idaho. However, multiple projects experienced delays of twelve to twenty-four months due to construction workforce shortages, equipment supply chain constraints, and complex negotiations with the CHIPS Program Office over grant conditions.

• The IRA's clean energy provisions triggered a manufacturing investment boom in solar panels, battery storage, and EV supply chains in Republican-held districts, creating a political dynamic that complicated subsequent Republican efforts to repeal IRA provisions. The 45X Advanced Manufacturing Production Credit for solar panels, wind components, and battery cells manufactured in the US attracted investment to states including Georgia, Michigan, Ohio, and South Carolina — states with Republican senators. By 2024, estimates from Princeton's REPEAT Project and other modellers suggested the IRA would achieve emissions reductions of approximately 40% below 2005 levels by 2030, compared to roughly 25–30% without the legislation. [TBD-VERIFY: 2030 projection figures are model-dependent and subject to revision]

• The Trump-2 administration (inaugurated January 2025) pursued selective rollback rather than wholesale repeal. Trump executive orders targeted IRA climate provisions and paused EV tax credit implementation; the administration sought to redirect some IRA funds toward fossil fuel development and reverse methane fee regulations. However, CHIPS funding proceeded with bipartisan congressional protection; the semiconductor fab investments already announced and partially under construction were politically and economically difficult to reverse. The IRA's clean energy tax credits proved more resilient than Trump's allies had promised, partly because the manufacturing investment had already been committed and partly because the credits were structured as entitlements — permanent features of the tax code requiring affirmative legislative repeal.

• The CHIPS-IRA legislative package demonstrated both the enduring capacity and the structural limits of the US political system to act on long-horizon strategic challenges. Congress passed two landmark laws within seven days in August 2022, after years of debate, because the national security framing of CHIPS created cross-party urgency and because Manchin's personal negotiation produced an IRA that was budget-neutral on ten-year CBO scoring. But the packages also showed persistent weaknesses: the IRA's healthcare provisions were modest compared to international peers; permitting reform — essential for accelerating clean energy buildout — failed in 2022; and the CHIPS Act's science and education provisions, though ambitious in dollar terms, faced implementation timelines of five to ten years before yielding research capacity.

2. The Policy Context: Why 2022 Was Different

For four decades following the Reagan administration, both Democratic and Republican economic teams operated within a broad consensus against sectoral industrial policy. The theoretical foundations were well established: government agencies lack the information to pick winners; subsidies invite rent-seeking and political capture; comparative advantage, not strategic national interest, should determine where industries locate. The practical result was a US manufacturing base that declined relative to its share of GDP and employment from the 1980s onward, a process dramatically accelerated by China's accession to the World Trade Organization in 2001.

The empirical challenge to this consensus came most forcefully from academic research. Autor, Dorn, and Hanson's 2013 paper "The China Syndrome" estimated that import competition from China accounted for 2.0 to 2.4 million manufacturing job losses in the United States between 1999 and 2011, with concentrated geographic effects in communities ill-equipped to absorb the dislocation. Subsequent research found persistent wage and employment suppression in affected labour markets for more than a decade, contradicting the standard trade model's prediction that displaced workers would relatively smoothly transition to other employment. This research provided the academic foundation for a political reappraisal that had been building since the 2016 election.

The COVID-19 pandemic provided the acute crisis that transformed abstract industrial policy arguments into immediate legislative action. In 2021, global semiconductor shortages halted production lines at Ford, General Motors, Toyota, and virtually every other major automotive manufacturer. The shortages revealed a structural dependency: approximately 90% of the world's most advanced semiconductors were manufactured in Taiwan, primarily by TSMC, and a further significant share in South Korea by Samsung and SK Hynix. Both concentrations were geographically proximate to potential Chinese military action. The US had retained semiconductor design leadership — companies such as Intel, Qualcomm, Apple, AMD, and Nvidia designed chips that ranked among the world's most advanced — but had steadily divested from domestic fabrication as production shifted to Asia over the preceding two decades.

The national security dimension of semiconductor concentration provided the political bridge that made CHIPS bipartisan. Defence Department assessments, intelligence community analysis, and think-tank research all converged on the same conclusion: US military systems, from aircraft carriers to precision munitions to communications infrastructure, depended on chips that were manufactured almost entirely outside the United States. Congressional leadership in both parties agreed that this was unacceptable. The legislation moved through committees with testimony from defence officials alongside semiconductor executives — a combination that made it very difficult for any senator or representative to vote against without facing characterisation as indifferent to national security.

The climate legislation's path was more tortured. The Biden administration had proposed a comprehensive Build Back Better Act that combined social spending ($1 trillion in childcare, elder care, and housing investment), clean energy incentives ($550 billion), and revenue measures. The legislative strategy depended on maintaining all fifty Democratic Senate votes for reconciliation passage, and Senator Joe Manchin of West Virginia — whose state was among the most coal-dependent in the country and who held his seat in a state that had voted for Trump by 39 percentage points in 2020 — repeatedly objected to both the scale of spending and the structure of clean energy provisions. On 19 December 2021, Manchin announced on Fox News that he would not vote for Build Back Better, effectively killing it.

The resurrection of climate legislation in the summer of 2022 required accepting Manchin's priorities: the deal that became the IRA was deficit-reducing on ten-year CBO scoring, included a methane emissions fee on oil and gas (which Manchin agreed to accept as a framework for regulatory compliance rather than a punitive measure against the industry), and was structured around tax credits rather than direct spending wherever possible. Tax credits, as entitlements written into the Internal Revenue Code, are both more durable politically and more predictable for investment planning purposes than discretionary appropriations that must survive annual budget negotiations.

3. The CHIPS and Science Act: Architecture and Implementation

The CHIPS and Science Act, formally the Creating Helpful Incentives to Produce Semiconductors and Science Act, was divided into two major components: the CHIPS for America Fund providing manufacturing incentives, and the CHIPS and Science authorisations providing research and education investment.

The manufacturing incentive structure had three tiers. The $39 billion CHIPS Manufacturing Incentives fund, administered by the Department of Commerce's newly created CHIPS Program Office, provided direct grants to semiconductor fabrication facilities constructed or expanded in the United States. A 25% investment tax credit for semiconductor manufacturing equipment purchases applied in addition to grants, providing a further incentive that reduced capital costs for facilities that might not qualify for direct grants but were investing in equipment upgrades. A $2 billion fund specifically for legacy semiconductors — nodes at 28 nanometres and above, critical for automobiles, medical devices, and defence applications — recognised that leading-edge fabrication was not the only supply chain vulnerability; older, less glamorous chip types had proven equally critical in the 2021 shortage.

The research and development provisions allocated $11 billion primarily for the National Semiconductor Technology Center, a public-private consortium designed to advance semiconductor research from fundamental science to manufacturing readiness. The NSTC model was partly inspired by IMEC in Belgium, which had become a world-leading semiconductor research centre through sustained government-industry partnership. Additional R&D funding was directed to the National Advanced Packaging Manufacturing Program — recognising that advanced chip packaging, which integrates multiple chips into a single high-performance module, was an increasingly important competitive frontier — and to a series of Manufacturing USA institutes focused on semiconductor-adjacent technologies.

The guardrail provisions were drafted to ensure that federal investment did not inadvertently benefit China's semiconductor industry through indirect channels. CHIPS grant recipients were prohibited from making any "significant transaction" involving the material expansion of semiconductor manufacturing capacity in a country of concern for a period of ten years following grant receipt. The provision extended beyond leading-edge chips (below 28nm) to any new material capacity expansion in China, with narrower exceptions for legacy-node capacity intended to serve Chinese domestic markets without transferring advanced technology. Companies including Intel, which operated fabrication facilities in China producing mature nodes, had to carefully navigate these provisions; several negotiations with the CHIPS Program Office over grant conditions reportedly involved extended discussions about compliance mechanisms and the treatment of existing China operations.

Implementation encountered delays that reflected both the scale of the undertaking and the gaps in US capacity to execute rapid industrial policy. The CHIPS Program Office needed to hire hundreds of technical experts capable of evaluating complex semiconductor manufacturing proposals and negotiating grant conditions with sophisticated counterparts at TSMC, Samsung, Intel, and Micron. Workforce availability for semiconductor fab construction proved to be a significant constraint: building an advanced fabrication facility requires specialised construction skills, particularly in cleanroom installation and process tool integration, that were in short supply after decades of minimal US fab construction. TSMC's Arizona fabs experienced well-publicised workforce disputes and delays, with TSMC initially attributing schedule slippage partly to differences between Taiwanese and American construction workforce practices — a characterisation that generated political controversy. [TBD-VERIFY: Specific timeline and attribution of TSMC Arizona delays]

The fab investment announcements that followed CHIPS passage were nonetheless remarkable in aggregate scale. TSMC committed to building two fabs in Phoenix, Arizona, initially targeting N4 process technology for the first fab (4nm-class) and N3 for the second, with a combined investment of $40 billion. In late 2024, TSMC announced a third Arizona fab, bringing total committed investment to approximately $65 billion — the largest foreign direct investment in US semiconductor history. Intel announced $20 billion in construction at its New Albany, Ohio campus for two leading-edge logic fabs, Fab 52 and Fab 62, intended to produce Intel's 18A process node and serve Intel Foundry Services customers. Samsung committed $17 billion to a new Taylor, Texas fab adjacent to its existing Austin facility. Micron Technology, the only remaining US-headquartered memory chip producer after Micron's acquisition of Elpida, announced $40 billion in domestic memory production investment in Clay, New York (DRAM) and Boise, Idaho (NAND). The aggregate announced investment — exceeding $130 billion across the four major recipients — far exceeded the $39 billion in direct grants, demonstrating significant leverage of public investment into private capital commitment.

4. The Inflation Reduction Act: Climate Architecture

The IRA's climate provisions were designed by energy policy experts who had spent years modelling what combination of incentives would most effectively accelerate clean energy deployment. The core design insight was that technology-neutral, durable tax credits provided more certain investment signals than sector-specific mandates or short-lived appropriations. The production tax credit (PTC) and investment tax credit (ITC) for clean electricity — extended and expanded to cover a wider range of technologies, including standalone battery storage that did not qualify under previous law — created a decade-long investment horizon that enabled project developers to make commitments confident that the economics would hold.

The clean electricity provisions were structured to phase out based on emissions thresholds rather than calendar dates: the new technology-neutral Clean Electricity PTC and ITC would begin phasing out only once power sector emissions had fallen to 25% of 2022 levels, creating an incentive structure that would self-terminate upon achieving its policy objective rather than requiring constant legislative renewal. This design was the product of intensive negotiation between energy policy advocates who favoured technology mandates and more market-oriented economists who favoured price signals; the resulting structure combined the investment certainty of mandates with the technology flexibility of market mechanisms.

The electric vehicle provisions were among the most politically consequential and technically complex elements of the IRA. The revised clean vehicle credit of $7,500 for new EVs replaced a previous credit that had expired for GM and Tesla (the two US manufacturers that had sold the most EVs) due to per-manufacturer sales caps. The IRA eliminated per-manufacturer caps but introduced new requirements: final assembly must occur in North America; battery components must meet rising thresholds (50% in 2023, rising to 100% by 2029) of US or free-trade-agreement country sourcing; critical minerals in the battery must meet similar thresholds. Income limits ($150,000 for individuals, $300,000 for joint filers) and vehicle price caps ($55,000 for cars, $80,000 for SUVs and trucks) were designed to target credits at middle-income purchasers rather than luxury EV buyers. A $4,000 credit for used EVs was introduced for the first time, substantially expanding access.

The advanced manufacturing production credit, Section 45X, provided per-unit production incentives for solar panels, wind turbine components, inverters, battery cells, and battery modules manufactured in the United States. This provision was distinctive in that it rewarded production rather than investment, creating incentives that scaled with output. For solar cells, the credit was $0.04 per watt of capacity; for battery cells, $35 per kilowatt-hour; for battery modules, $10 per kilowatt-hour. The credits were transferable — manufacturers could sell the credits to tax equity investors — making them accessible to companies without large tax liabilities. The 45X credits attracted rapid responses from manufacturers: First Solar (US), Qcells (Korean), and a series of Chinese-owned but US-located manufacturers began or accelerated US solar manufacturing projects within months of passage.

The clean hydrogen production credit, Section 45V, provided a tiered credit of $0.60 to $3.00 per kilogram of clean hydrogen based on life-cycle greenhouse gas intensity, with the full credit available to hydrogen produced with 95% lower emissions than conventional grey hydrogen. The hydrogen credit attracted substantial controversy over the life-cycle accounting methodology — specifically whether electrolytic hydrogen using grid electricity should receive credit for renewable power purchased through contracts or certificates, or only for renewable power demonstrably added to the grid in the same location and time period. The Treasury Department's final rules, published in late 2024, adopted an additionality, deliverability, and temporal-matching framework that tightened eligibility, reducing projected hydrogen investment compared to initial industry expectations.

5. The Schumer-Manchin Negotiation and Revenue Architecture

The political achievement of the IRA was inseparable from the personal negotiation between Senate Majority Leader Chuck Schumer and Senator Joe Manchin that produced the 27 July 2022 framework announcement. Manchin had killed Build Back Better in December 2021 with a Fox News Sunday appearance stating that he could not vote for the bill due to concerns about inflation, deficits, and the structure of climate provisions. In the intervening seven months, Schumer maintained a quiet negotiating channel with Manchin, making concessions on the bill's structure while the public political drama played out.

The revenue provisions that made the IRA deficit-neutral on CBO scoring were among the most significant in tax policy terms. The 15% corporate alternative minimum tax, applicable to corporations reporting $1 billion or more in profits to shareholders for three consecutive years, was designed to address the phenomenon of large, profitable companies using tax deductions and credits to pay very low effective tax rates on their book income. The Carried Interest provision — which Manchin had specifically demanded to close the treatment of hedge fund and private equity managers' compensation as capital gains rather than ordinary income — was ultimately stripped from the bill at Senator Kyrsten Sinema's insistence in exchange for her vote, replaced by a 1% excise tax on corporate stock buybacks. The IRS enforcement funding of $80 billion over ten years was projected by the CBO and independent analysts to generate revenues of $200 billion or more by funding enforcement activities focused on high-income earners and corporations — a significant revenue offset built on the documented gap between taxes owed and taxes paid.

The healthcare provisions of the IRA, while receiving less attention than the climate provisions, represented long-sought policy changes of significant magnitude. The authorisation for Medicare to negotiate drug prices for the first time — with ten drugs selected for negotiation in the first round, effective 2026 — ended a legislative prohibition that had stood since the Medicare Prescription Drug, Improvement, and Modernization Act of 2003. The out-of-pocket cap for Medicare Part D prescription drug costs, set at $2,000 per year beginning 2025, directly affected the finances of millions of Medicare beneficiaries whose drug costs had in some cases exceeded $10,000 or $20,000 annually. The extension of ACA marketplace subsidies from the American Rescue Plan (see US-D-02) through 2025 prevented a subsidy cliff that would have raised premiums for approximately 13 million marketplace enrollees.

Manchin's insistence on permitting reform as a condition of his IRA support reflected a genuine policy concern — that clean energy buildout would be severely constrained by the existing environmental review and permitting process for transmission lines and generation facilities — but this element of the deal failed to survive into law. A permitting reform bill, the Building American Energy Security Act negotiated by Manchin and Senate Republican John Barrasso, was attached to a continuing resolution in December 2022 but stripped from the final spending bill when House progressive Democrats and some Senate Democrats objected to provisions they regarded as weakening environmental review for fossil fuel infrastructure. The failure of permitting reform remained a significant constraint on IRA implementation through 2025: numerous wind and solar projects with signed power purchase agreements could not connect to the grid due to transmission permitting backlogs.

6. The "New Washington Consensus" and Strategic Framing

The Biden administration's economic policy team worked to articulate a theoretical framework for the CHIPS-IRA approach that went beyond the specific legislation to argue for a broader reorientation of US economic strategy. The clearest articulation came from National Security Advisor Jake Sullivan in his April 2023 Brookings Institution speech, titled "Renewing American Economic Leadership."

Sullivan identified four failures of the old Washington Consensus as applied to international economic strategy. First, it had led to "hollowing out" of the US industrial base and supply chains without adequate assessment of the national security implications of concentration. Second, it had failed to anticipate how government-directed economies — primarily China's — would use market access to extract technology, subsidise strategic industries, and build structural dependencies. Third, it had produced economic growth that was insufficiently broad, leaving workers in deindustrialised regions without economic alternatives and creating the political conditions for backlash. Fourth, it had failed to mobilise private investment at the scale required to address climate change within the relevant time horizon.

Sullivan's "new Washington consensus" proposed to correct these failures through what he characterised as targeted public investment rather than comprehensive industrial planning. The distinction was important: Sullivan was not arguing for government to allocate capital across the economy, but for government to identify specific areas — semiconductor manufacturing capacity, clean energy infrastructure, critical mineral supply chains — where market incentives alone were producing outcomes incompatible with national security or climate objectives, and to intervene with incentives sufficient to alter investment patterns.

The intellectual genealogy of this approach drew on Dani Rodrik's work on industrial policy, which had distinguished between market failures that justify intervention and the political economy risks of intervention captured by incumbent interests, and on the "productivist" wing of American economic thought represented by figures such as Oren Cass and Michael Lind — an unusual intellectual synthesis that crossed traditional left-right boundaries. The Biden administration was explicitly reaching for bipartisan legitimacy by framing industrial policy in national security terms and by emphasising manufacturing employment in communities that had experienced significant deindustrialisation.

Internationally, the Biden team framed CHIPS-IRA as consistent with a broader allied strategy of "friend-shoring" — building supply chains within a network of democratic allies rather than relying on global integration that included potential adversaries. The CHIPS guardrails preventing expansion in countries of concern, the IRA's critical minerals provisions favouring FTA partner countries, and the Commerce Department's export controls on advanced semiconductors to China (announced October 2022, tightened subsequently) formed an integrated economic security architecture. The Semiconductor Alliance with Japan and the Netherlands — both home to critical semiconductor equipment suppliers (Tokyo Electron and ASML respectively) — reinforced the multilateral dimension of what was structured as domestic legislation.

7. Allied Reactions and the IRA Trade Controversy

The IRA's domestic-content requirements provoked the sharpest allied reaction to any US economic policy in the post-COVID period. European Commission President Ursula von der Leyen described the IRA as potentially "discriminatory" toward European companies; French President Emmanuel Macron warned of a "super-aggressive" US industrial policy that would divert investment from Europe; German Chancellor Olaf Scholz expressed concern that the combination of IRA and US domestic energy price advantages would accelerate deindustrialisation of European manufacturing.

The core European concern was that the IRA's EV tax credit, with its North America assembly requirement, effectively excluded European-manufactured EVs from the US market benefit while simultaneously attracting European automotive supply chain investment to the United States. Volkswagen, BMW, and other European automakers that had been planning North American EV investments accelerated those plans under IRA incentives. Meanwhile, the battery mineral sourcing requirements favoured countries with US free trade agreements — including Canada, Mexico, South Korea, Australia, and Chile — over EU member states, none of which have formal FTAs with the United States.

The Biden administration's response was to negotiate a series of "critical minerals agreements" that were designed to function as narrow trade agreements qualifying for IRA FTA provisions without requiring Senate ratification. The EU-US Critical Minerals Agreement framework, announced in October 2023, covered lithium, cobalt, nickel, manganese, and graphite sourced from EU member states, qualifying them for IRA battery mineral requirements. Similar arrangements were concluded with Japan and the United Kingdom. The legal structure of these arrangements was contested: some trade lawyers argued they were inconsistent with WTO most-favoured-nation rules; others argued they were legitimate national security exceptions. [TBD-VERIFY: Legal status of critical minerals agreements]

South Korea's response was particularly notable for its speed and specificity. Korean battery manufacturers — LG Energy Solution, SK On, and Samsung SDI — and automotive companies had significant existing US investments and were well-positioned to qualify under IRA domestic-content requirements. The Korean government negotiated specific provisions for "foreign entities of concern" restrictions that would affect Korean companies supplying components to Chinese joint ventures, and worked with US Treasury on rules that preserved Korean battery manufacturers' access to IRA credits. Hyundai, which had announced a $5.5 billion EV and battery manufacturing complex in Bryan County, Georgia, benefited from IRA incentives while simultaneously negotiating with the Biden administration over the timing of North America assembly requirements for its EVs.

The IRA's implications for China were more complex than the EV provisions suggested. China had by 2022 established dominant positions in solar panel manufacturing (approximately 80% of global production), battery cell manufacturing (approximately 75% of global production), and critical mineral processing (approximately 60–70% of global lithium processing). The 45X advanced manufacturing credits would subsidise US and allied production that competed directly with Chinese manufacturers, but the speed with which Chinese supply chain advantages could be replicated in the United States was deeply uncertain. Some Chinese solar manufacturers established US manufacturing operations specifically to qualify for 45X credits; the rules distinguishing qualifying US manufacturing from disguised final assembly of Chinese components became a significant compliance and enforcement challenge.

8. Contested Record

The CHIPS Act and the IRA were among the most consequential pieces of economic legislation in a generation, but their strategic assessment remained genuinely contested across dimensions that cannot be resolved by reference to first principles alone.

Is the US industrial policy revival strategically sound, or economically distortive?

Proponents argued that the combination of market failures, national security imperatives, and climate urgency created legitimate grounds for public investment that the post-1980 consensus had wrongly foreclosed. The semiconductor case was strongest: the geographic concentration of advanced fabrication in a potential conflict zone, combined with the defence-critical nature of chips, provided a textbook national security market failure. The clean energy case rested on the external costs of carbon emissions (a market failure) compounded by the first-mover advantages that China's industrial policy had built in solar and batteries — advantages that private US investment alone could not overcome quickly enough to meet climate objectives or to build competitive manufacturing positions.

Critics from the economic right argued that the CHIPS grants would prove redundant — that TSMC, Samsung, and Intel had commercial incentives to invest in the United States without $39 billion in subsidies, and that the grants effectively transferred rents to shareholders of companies that would have invested anyway. The Peterson Institute for International Economics estimated that the EV content requirements would cost consumers more per tonne of carbon abated than alternative policies. Critics further argued that domestic-content requirements violated WTO obligations, inviting retaliation that would damage US exports in sectors unrelated to semiconductors or clean energy.

Critics from the economic left argued that the IRA's reliance on tax credits rather than direct investment ceded too much control to private actors, replicated existing inequalities in who had access to capital, and produced investment patterns driven by tax optimisation rather than optimal climate outcomes. The decision to extend the production tax credit to nuclear power — a politically sensitive addition to win specific senators' votes — was celebrated by nuclear advocates as long overdue and criticised by others as subsidising a technology whose economics remained challenging without resolving its waste disposal and safety challenges.

Can the US actually build a domestic semiconductor industry in a decade?

The scale of the challenge should not be understated. Taiwan's semiconductor industry was built over five decades through sustained government-industry partnership, starting with TSMC's founding in 1987 as a deliberate act of industrial policy by the Taiwan government, and benefiting from a deep ecosystem of equipment suppliers, materials companies, engineering talent, and process knowledge accumulated through millions of iterations. South Korea's industry involved similarly generational investment. The United States in 2022 had retained design leadership but had largely divested from leading-edge fabrication; rebuilding that capability required not just buildings and equipment but workforce, process knowledge, and supply chain ecosystems that took decades to develop.

The delays in CHIPS-funded projects illustrated this challenge. TSMC's Phoenix fabs encountered workforce shortfalls, equipment delivery delays, and utility infrastructure gaps that required significant public investment in water, power, and transportation to resolve. The timeline for the first Phoenix fab's production was pushed back from 2024 to 2025; the second fab's schedule slipped by multiple years. The question of whether the US could build a self-sustaining semiconductor ecosystem — rather than hosting offshore subsidiaries of Asian companies that would remain dependent on Asian supply chains and talent for critical processes — remained open. Some analysts argued that the real strategic objective should be resilience through diversification (multiple allies hosting some leading-edge production) rather than US self-sufficiency (which might require two to three decades and many hundreds of billions of dollars).

Will the IRA achieve its climate objectives under political pressure?

The IRA's clean energy provisions were structured as entitlements — permanent features of the tax code requiring affirmative legislation to repeal. This structural feature provided significantly more durability than discretionary programme appropriations, but it did not make them invulnerable to modification. The Trump-2 administration's efforts to redirect IRA funds and restrict EV credits created legal and administrative uncertainty that dampened some investment during 2025. The permitting reform failure meant that even fully-funded clean energy projects faced multi-year delays in grid connection, potentially constraining the IRA's effective emissions impact regardless of investment levels.

Princeton's REPEAT Project and Rhodium Group modelled IRA outcomes under various implementation scenarios. The central case projected emissions reductions of 38–43% below 2005 levels by 2030, significantly above the 25–30% projected without IRA, but still below the Biden administration's NDC commitment of 50–52% below 2005 levels. Achieving the full commitment required additional measures — particularly in buildings, industry, and transportation — beyond what the IRA alone provided. [TBD-VERIFY: Specific percentage ranges from Princeton REPEAT Project]

The China competition question:

Whether CHIPS-IRA would succeed in building durable US competitive advantage in semiconductors and clean energy, or whether it would prove a costly subsidy competition that China's scale advantages and state capacity would ultimately overwhelm, was among the most consequential strategic questions in early-21st-century economic governance. China's response to US export controls and CHIPS included accelerated domestic semiconductor investment through the National Integrated Circuit Industry Investment Fund (the "Big Fund"), targeted support for domestic equipment suppliers to reduce dependence on ASML and other Western tools, and continued dominance of clean energy manufacturing supply chains. The outcome of this competition — whether the US and its allies could build sufficient manufacturing resilience in strategic technologies, or whether the attempt would prove too slow, too expensive, and too dependent on Chinese-controlled supply chains — would not be apparent for years or decades.

9. Conclusion

The CHIPS and Science Act and the Inflation Reduction Act, signed within seven days in August 2022, represented a historical inflection point in US economic governance. They were not simply large spending bills; they embodied a deliberate rejection of the consensus that had governed US economic policy for four decades, asserting that strategic public investment in specific sectors — where market failures, national security imperatives, or climate urgency warranted intervention — was compatible with, and indeed required by, American national interest.

The CHIPS Act addressed a specific, acute vulnerability: the concentration of advanced semiconductor fabrication outside the United States, with particular risk from Taiwan's proximity to potential conflict with China. The legislation attracted significant bipartisan support because the national security framing was difficult to contest and the private sector had clearly failed, on its own, to maintain the diversified fabrication geography that defence planners required. Whether the investments catalysed by CHIPS will build a genuinely self-sustaining US semiconductor ecosystem, or whether they will succeed only in hosting offshore operations of Asian companies that remain strategically dependent on Asian ecosystems, will be determined over the next decade.

The IRA addressed the longer-horizon but equally urgent challenge of decarbonisation within a political environment that had previously resisted comprehensive climate legislation for thirty years. Its achievement was to find the specific combination of tax credit structures, revenue measures, and political concessions that could secure a Senate majority in a body that systematically overrepresents fossil-fuel-dependent states. Its limitations were those of any legislation designed to survive a narrow political window: it was too small to achieve US climate commitments without additional measures, it was structured around market incentives that favoured actors with capital and tax liabilities, and it remained vulnerable to subsequent political modification.

Together, CHIPS and IRA signalled to both domestic actors and international partners that the United States was prepared to use state capacity to shape economic outcomes in strategic domains — a signal that itself had effects, accelerating allied industrial policy responses (the EU's Green Deal Industrial Plan, Japan's Green Transformation programme, South Korea's K-Chips Act) and forcing companies to make strategic choices about supply chain geography that would not have been made on pure market logic. Whether this intervention represented a durable reorientation of US economic governance or a temporary departure from market consensus that would be reversed under different political conditions remained, as of 2025, an open question — one that the political turbulence of the Trump-2 transition had sharpened but not yet resolved.
