Trump's First Year in Review: A Mixed Economic Bag with Tariffs and Inflation in Focus
In a retrospective that's got traders revisiting their 2025 bets, Business Insider's deep dive into seven key charts highlights how the U.S. economy has evolved during Donald Trump's inaugural year of his second term. Inflation, which hovered around 2.5% at inauguration, has ticked up to 3.1% by late 2025, largely due to escalated tariffs on imports from China and the EU—now averaging 25% on key goods like electronics and autos. Job growth remains robust at 210,000 monthly additions, outpacing pre-election forecasts, buoyed by manufacturing repatriation incentives. However, federal spending has ballooned to $7.2 trillion annually, fueled by infrastructure pushes and defense hikes, pushing the deficit to 6.8% of GDP.
From an investor's lens, this paints a bifurcated picture: cyclical sectors like industrials (up 12% YTD) and materials are thriving on "America First" policies, but consumer discretionary faces headwinds from higher input costs. The USD has strengthened 8% against major currencies, pressuring exporters—watch Caterpillar (CAT) and Boeing (BA) for tariff ripple effects. If these trends hold, expect Fed Chair Powell's upcoming testimony to signal no rate cuts before Q3, keeping bond yields elevated around 4.2% on the 10-year Treasury. Key takeaway: Position for rotation into value stocks if tariff escalations materialize, but hedge against inflation surprises with TIPS or energy plays.
Investor takeaways
- Tariffs and inflation remain the key macro swing factors (inflation up to 3.1% by late 2025).
- Cyclicals (industrials/materials) benefiting; consumer discretionary pressured by higher input costs.
- Stronger USD (+8%) may weigh on exporters; watch CAT and BA for ripple effects.
- Rates likely higher-for-longer; 10Y around 4.2% with no cuts before Q3 implied.
AI Bubble Alert: Grantham's Dire Warning Could Spark Tech Sell-Off
Veteran investor Jeremy Grantham, co-founder of GMO, dropped a bombshell that's reverberating through tech trading desks: AI is "obviously a bubble" akin to the 19th-century railroad mania and the dot-com frenzy, with "slim to none" odds of a soft landing.
In his latest interview, Grantham lambasts the hype around Nvidia (NVDA) and peers, noting valuations at 50x forward earnings despite slowing enterprise adoption rates dipping below 40%. He predicts a burst could shave 30-50% off the Nasdaq, dragging broader indices into correction territory.
This isn't just hot air—GMO's funds have trimmed AI exposure by 25% in Q4 2025, reallocating to undervalued cyclicals. Counterpoints abound: Today's funding news for Emergent, a "vibe coding" startup that lets novices build apps via AI prompts, snagged $70 million from Khosla Ventures and SoftBank at a $300 million valuation. This underscores AI's real productivity gains, like Steven Bartlett's "Diary of a CEO" podcast, which used AI translation to boost Spanish listenership by 150%, expanding ad revenue. Nvidia's Jensen Huang influence also shines through in startup lore, with ex-employees crediting his leadership ethos for AI ventures like Blitzy.
Investor impact
Tech-heavy portfolios are vulnerable—NVDA dipped 2% in after-hours on Grantham's comments, while broader semis like AMD and TSM could follow if sentiment sours. Yet, AI infrastructure spend is projected to hit $200 billion in 2026 (per Gartner estimates), suggesting a "bubble within innovation."
Strategy
- Trim frothy names like NVDA above $150, but hold diversified AI enablers like Microsoft (MSFT) for long-term tailwinds.
- Volatility traders: eye VIX spikes above 20 as a sell signal.
Trade Bluster and Musk's Airline Antics: Geopolitical Jitters Meet M&A Buzz
Trump's renewed Greenland saber-rattling—threatening tariffs on Denmark unless the U.S. gains strategic footing—has analysts dusting off the "TACO" acronym: Trump Always Chickens Out. JPMorgan outlines three scenarios: (1) Diplomatic thaw via U.S.-Denmark pacts, boosting defense stocks like Lockheed Martin (LMT) by 5-7%; (2) Escalated tariffs hitting EU autos (e.g., Volkswagen, BMW), pressuring transatlantic trade; or (3) Full retreat, easing market fears. Probability tilts to scenario one at 60%, per JPM, but don't sleep on volatility—S&P 500 futures wavered 0.4% on the news.
Adding fuel, Elon Musk's X poll on acquiring Ryanair (post-Starlink WiFi spat) has the low-cost carrier's shares popping 3% in London pre-market. With Ryanair's €20 billion market cap and Musk's history of disruptive bids (recall Twitter), this could ignite airline M&A speculation. Watch United Airlines (UAL) and Delta (DAL) for sympathy moves, but regulatory hurdles loom large under Trump's FTC scrutiny.
Broader market sentiment: These flashes of policy unpredictability amplify risk-off flows into gold (hovering at $2,450/oz) and safe-haven CHF. Crypto, meanwhile, shrugs it off—Elon Effect or not—with Bitcoin steady above $95,000.
Scenario 1 (60%): Diplomatic thaw
U.S.-Denmark pacts; defense names like LMT +5–7% (per JPM).
Scenario 2: Escalated tariffs
EU autos (Volkswagen, BMW) pressured; transatlantic trade risk rises.
Scenario 3: Full retreat
Market fears ease; volatility fades if rhetoric cools.
Outlook: Cautious Stance Amid Crosscurrents
Global markets enter the day with a neutral-to-bearish tilt, S&P futures flatlining after yesterday's 0.2% gain. Earnings season ramps up with Tesla (TSLA) reporting after close—expect AI/robotaxi updates to counter Grantham's gloom. Key levels: S&P resistance at 5,800, support at 5,650; Nasdaq eyes 19,500 pullback. For active traders, focus on tariff-sensitive ETFs like XLI (industrials) for dips, and AI shorts via leveraged products if momentum fades. Stay nimble—Trump's economy may be resilient, but bubbles and bluster demand vigilance.
Key levels
- S&P 500 resistance: 5,800
- S&P 500 support: 5,650
- Nasdaq: 19,500 pullback level
Today’s focus
- TSLA earnings after close (AI/robotaxi commentary).
- Tariff-sensitive: XLI dips; exporters CAT/BA watch.
- AI sentiment: NVDA/AMD/TSM; VIX > 20 as risk signal.
