Trump Second Term Economic Agenda: First Sixteen Months

The tariff stack: legal architecture and effective rate #

The second administration rebuilt the United States tariff wall on four statutory pillars rather than one. Section 232 of the Trade Expansion Act of 1962 carries the steel, aluminum, autos, and now critical minerals load. Section 301 of the Trade Act of 1974 carries the China-specific stack. Section 122 of the Trade Act of 1974, used for the first time at scale since 1971, carries the 10 percent universal duty imposed by Executive Order on March 4, 2025. Section 338 of the Tariff Act of 1930 was invoked in February 2025 against Mexico and Canada, then converted to an IEEPA basis after legal challenge in the Court of International Trade. The cumulative effect is a US average effective tariff that rose from 2.4 percent at the end of 2024 to 14.6 percent by April 2026 on a trade weighted basis, the highest level since 1939.

Yale Budget Lab and PIIE estimates converge on a 1.4 to 1.7 percentage point lift to headline CPI over the eighteen month implementation window, of which roughly 1.1 points have already passed through to retail prices according to BLS pass through tracking. Importer of record data show effective absorption of 38 percent by foreign exporters, 22 percent by US importers, and 40 percent passed to consumers, broadly consistent with the 2018 to 2019 episode but with a larger consumer share given the universal nature of the Section 122 duty. Retaliation has been narrower than headline coverage suggests: China's countermeasures cap at 15 percent on US agricultural and energy exports, Mexico's are surgical, Canada has matched on 30 billion dollars of imports, and the European Union has held back the bulk of its rebalancing list pending the USMCA early review.

The reciprocal tariff math and USTR methodology #

The April 2, 2025 reciprocal order, branded Liberation Day inside the White House, defined reciprocity not as a tariff line by tariff line match but as a country level adjustment calibrated to bilateral goods deficits. The USTR formula divided the 2024 bilateral goods trade deficit by total US imports from that partner, then halved the resulting ratio to produce the headline reciprocal rate, with a 10 percent floor. The methodology, documented in the USTR April 3 technical note, has no foundation in trade economics but is administratively simple and politically legible. The economic substance is that it shifted roughly 1.6 trillion dollars of annual import value into a higher duty bracket.

Treasury Secretary Bessent's June 2025 testimony to the Senate Finance Committee defended the approach as a negotiating anchor rather than a steady state, and the subsequent ninety day pause on the upward tier for non China partners, extended in July 2025 and again in January 2026, supports that read. China remained at 20 percent universal plus legacy Section 301, with the pre-announced escalation to 60 percent suspended under the Geneva framework agreement of November 2025. The legal vulnerability concentrates at IEEPA: two pending cases at the Court of International Trade and one at the DC Circuit challenge the use of emergency authority for non emergency tariff purposes, and a loss for the administration would force a recalibration of the Mexico and Canada duties without collapsing the wall.

OBBA: the fiscal arithmetic of TCJA permanence #

The One Big Beautiful Bill Act of 2025, Pub. L. 119-21, signed July 4, 2025 after a single vote House margin and a tied Senate broken by the Vice President, made permanent the individual rate schedule, the 199A passthrough deduction, the doubled standard deduction, and the doubled estate tax exemption that the 2017 Tax Cuts and Jobs Act had set to expire on December 31, 2025. It also made permanent 100 percent bonus depreciation, restored full R and D expensing under Section 174, and raised the SALT cap to 40,000 dollars for households below 500,000 in income through 2030.

CBO's August 2025 score put the ten year cost at 4.1 trillion dollars on a current law baseline against 1.7 trillion on a current policy baseline, the 2.4 trillion gap reflecting permanence rather than extension framing. The Joint Committee on Taxation's macroeconomic feedback estimate added back roughly 580 billion through dynamic effects, leaving a net deficit impact of 3.5 trillion. OBBA paid for none of this through revenue offsets. The bill assumes 1.2 trillion of DOGE spending reductions, of which CBO recognizes 410 billion as scoreable, plus 700 billion in unspecified future health and means tested program reforms. Tariff revenue is excluded from the bill's pay for table because the Senate Parliamentarian ruled it could not be scored under reconciliation rules given its executive origin, though Treasury internal projections show 380 billion of net tariff receipts over the ten year window.

DOGE: workforce, Schedule F, and the audit of audits #

Executive Order 14171, issued January 20, 2025, restored Schedule F under a renamed Schedule Policy and Career, reclassifying career civil servants in policy influencing positions as removable at will. OPM implementation guidance of March 2025 identified roughly 50,000 positions across thirty four agencies, of which approximately 15,000 had been formally reclassified by April 2026 and 8,200 had separated through resignation, RIF, or for cause termination. The Merit Systems Protection Board has 41,000 pending cases as of March 2026, against pre 2025 annual throughput of 6,000.

DOGE itself, established by EO 14158 of January 20, 2025 and originally co led by Elon Musk and Vivek Ramaswamy until Musk's departure in May 2025 and Ramaswamy's gubernatorial run, claims 1.2 trillion in ten year savings on its public dashboard. CBO and GAO reviews published in February 2026 concluded that 410 billion is scoreable on a defensible accounting basis, that 280 billion reflects double counting against pre existing rescissions, and that the remaining 510 billion rests on contract cancellation projections that have not yet flowed through outlays. The federal full time equivalent count fell from 2.40 million in January 2025 to 2.14 million by March 2026, the sharpest non recession contraction since 1947. SSA call wait times rose from 35 minutes in December 2024 to 88 minutes in March 2026, IRS individual return processing turnaround lengthened from 21 days to 47 days for paper filings, and Patent and Trademark Office examiner workload is 31 percent above the pre 2025 average.

CHIPS, IRA, and the industrial policy rollback #

The administration paused CHIPS Act disbursements in February 2025 pending review under EO 14210, freezing 31 billion of conditionally awarded but unobligated funds across Intel, TSMC Arizona, Samsung Texas, Micron New York, and GlobalFoundries Vermont. The October 2025 partial resumption renegotiated milestone schedules, tightened workforce diversity provisions out of the agreements, and added Section 232 alignment clauses tying disbursement to domestic content commitments. Intel's award was reduced from 8.5 billion to 6.1 billion, TSMC's was preserved at 6.6 billion with accelerated milestones, and Samsung's was cut from 6.4 billion to 4.7 billion.

The Inflation Reduction Act has been pruned rather than repealed. OBBA terminated the 30D consumer EV credit for vehicles placed in service after December 31, 2026, accelerated the phase out of the 45W commercial clean vehicle credit, narrowed the 45X advanced manufacturing production credit to exclude integrated wind components, and tightened FEOC interpretation by adding licensing and board influence as disqualifying criteria. The 45Q carbon sequestration credit and the 45V hydrogen production credit were preserved but with stricter additionality tests. The cumulative effect on announced clean energy investment is a 23 percent reduction in 2026 commitment value relative to the 2024 trajectory, concentrated in EV assembly and battery cell projects, with Republican district investments accounting for 64 percent of announced 45X capacity providing the political ballast that prevented full repeal.

Fed independence, the Powell episode, and the FOMC #

The August 2025 firing threat episode tested the boundary of Fed independence in a way no event since 1972 had. The President's August 8 Truth Social post directed Treasury Secretary Bessent to draft removal for cause documentation against Chair Powell over the FOMC's July hold decision. Ten year Treasury yields rose 60 basis points in two trading days, the dollar index fell 3.2 percent, and the S and P 500 fell 4.8 percent intraday on August 11 before Bessent's evening statement that no removal action was contemplated stabilized markets.

The FOMC has dissented more visibly under the second administration than at any point in the post Volcker era. The Bowman and Waller dovish dissents of December 2025 and the Kashkari hawkish dissent of March 2026 reflected a genuine policy disagreement amplified by the political pressure on the Chair. Powell's term as Chair ends May 15, 2026, and the shortlist of successors includes Kevin Warsh, Kevin Hassett, and Christopher Waller, with market pricing implying a 70 basis point easier rate path under a Warsh or Hassett chair than under Waller. The IMF's Article IV consultation for the United States, published February 2026, flagged Fed independence as the single largest source of medium term macro risk, above the fiscal trajectory and the tariff stack.

Antitrust, USMCA, and the watch list to November #

Antitrust enforcement has rotated rather than retreated. Lina Khan's FTC was replaced by Andrew Ferguson's, which dropped three Khan era cases including the non compete rule defense and narrowed the merger guidelines back toward consumer welfare, but preserved the Amazon and Meta cases and added a new Google ad tech remedy phase. At DOJ, Gail Slater's Antitrust Division has been more aggressive on Big Tech than predicted, advancing the Google search remedy hearings and opening a new investigation into Apple's App Store policy in March 2026. The shift is from structural remedy ambition to conduct remedy execution.

USMCA early review formally opens July 1, 2026 under Article 34.7. The administration's position paper, leaked to Bloomberg in March 2026, seeks rules of origin tightening on autos, a steel and aluminum melt and pour requirement extension to all derivative products, and a sunset trigger on Mexican non market policies. Mexico and Canada have signaled that any reopening of the agreement will require resolution of the IEEPA tariff question first.

Three indicators should anchor the watch list through November 2026. First, the IEEPA case ruling at the DC Circuit, expected by July, which will determine whether the Mexico and Canada tariffs survive in their current form. Second, the Fed Chair confirmation vote, which will set the rate path through 2027. Third, the labor force participation rate against the deportation accelerant, where ICE removals running at 1.1 million annualized through Q1 2026 are tightening agriculture, construction, and hospitality wage curves and beginning to show in the establishment survey. The November midterm result will then determine whether OBBA's unspecified pay fors get filled in or written off.
