Trump's First 100 Days: Economic Impact, Stock Market, Tariff Revenue

---

The Stock Market Shock

Financial markets entered Trump's second inauguration at elevated valuations, having priced in a business-friendly agenda centered on deregulation and corporate tax cuts. What they did not anticipate was the speed and breadth of the tariff escalation. When the administration announced a universal 10% baseline tariff on all imports within the first six weeks, markets absorbed the shock. When 25% tariffs on Canada and Mexico followed — disrupting deeply integrated North American supply chains — the S&P 500 began a sustained decline. Technology companies with Asian manufacturing dependencies, auto manufacturers reliant on cross-border parts flows, and consumer discretionary companies facing input cost inflation all saw significant selloffs. By the 100-day mark, the index was down approximately 8% from inauguration day — the steepest opening-100-days decline for any new presidential term since 2009.

GDP: Import Front-Running Distorts the Data

The Q1 2025 GDP figure of +0.4% annualized was particularly alarming because it was distorted in a direction that made the underlying economy look stronger than it was. A surge in imports before tariff deadlines widened the trade deficit sharply, subtracting from GDP. Stripping out trade and inventory movements, final domestic demand — consumer spending plus business investment plus government purchases — grew at roughly 1.6% annualized. That is still considerably below the 2.5%–3.0% range of late 2024, and business fixed investment contracted for the first time since 2022, suggesting firms were already pulling back on capital spending in response to tariff-driven uncertainty. Q2 data, expected in late July 2025, is projected by major forecasters to show a near-zero or marginally negative print.

Tariff Revenue: Real but Overstated

The Trump administration pointed to rising tariff revenue as evidence that the policy was working. Monthly collections roughly doubled from the pre-tariff baseline, with the Treasury reporting approximately $7.2 billion in monthly tariff revenue by April 2025 versus $3.5 billion in January. Annualized, that approaches $85 billion — a meaningful fiscal figure. The administration positioned this as foreign countries paying a "tax" on their exports. Economists broadly dispute this framing: tariffs are paid by domestic importers at the point of entry and are then passed through to business customers or end consumers via higher prices. The net effect is a transfer from American consumers to the federal government, with additional deadweight economic losses from trade diversion and reduced volume. The CBO's analysis found that the tariff regime was adding roughly $1,300 per year in costs to the average American household.

Jobs: Headline Stable, Quality Mixed

The labor market held up better than financial markets or GDP in the first 100 days. Non-farm payrolls continued to grow at a modest pace, and the unemployment rate ticked up only marginally from 4.1% to 4.3% — still historically low. However, the composition of job growth shifted: goods-producing industries, particularly manufacturing, shed jobs as higher input costs squeezed margins. Service sector hiring in leisure, hospitality, and healthcare continued. The federal workforce reduction program (DOGE) contributed to public-sector job losses for the first time in years, with federal employment declining by an estimated 150,000 – 200,000 over the period. State and local government employment partly offset this. The JOLTS survey showed job openings declining, a leading indicator that the headline unemployment rate may rise further through 2025.

Consumer Confidence and What It Means for 2026

The Conference Board's Consumer Confidence Index, which stood at 105 when Trump took office, fell to 92 by April 2025 and continued declining through the year, reaching its lowest levels since 2020 by early 2026. This matters enormously for the 2026 midterm cycle. Historical data is unambiguous: presidents whose approval ratings fall and whose consumer confidence numbers deteriorate in the 12–18 months before a midterm election face significant congressional losses. The pattern held in 1994, 2006, 2010, and 2018. The economic data through the first 100 days of Trump's second term sets up the structural headwinds for November 2026 — and they are real.
