Under Biden, America got 150 countries to agree a 15% global corporate tax. Under Trump, America gets an exemption

The OECD announced that nearly 150 countries agreed on a revised global tax plan that effectively excludes large U.S.-based multinationals from a previously agreed 15% global minimum corporate tax after negotiations led by the Trump administration. The amendment, hailed by U.S. officials as preserving sovereignty, waters down the 2021 deal aimed at stopping profit-shifting to tax havens and has drawn criticism from tax transparency groups; the change may preserve lower effective tax burdens for the largest U.S. multinationals and carry implications for cross-border tax planning and investor valuations.

Analysis

Market structure: The carve-out materially preserves an after-tax cashflow edge for large US multinationals that book significant profits offshore (tech, consumer brands, pharma). Expect a relative valuation re-rate: 1–3% incremental EPS accretion over 12–24 months for firms with 20–40% offshore profit shares, translating into stronger buyback/capex capacity and modestly tighter credit spreads for mega-caps.

Risk assessment: Tail risks include rapid policy reversal after elections, retaliatory unilateral taxes by other jurisdictions, or supranational litigation—each could wipe out 5–15% of the re-rate within 3–12 months. Near-term (days-weeks) reaction will be headline-driven; medium-term (quarters) depends on corporate guidance; long-term (years) on treaty re-writes and enforcement mechanics.

Trade implications: Direct beneficiaries: AAPL, NKE, large-cap US software and pharma—trade via equities or 12–24 month LEAP calls to capture multi-quarter EPS roll-through. Relative trades: long US multinational heavy indices vs short Europe/ex-US multinationals (VGK/STOXX600) to exploit jurisdictional tax arbitrage; protect with 3–6 month puts on ex-US ETFs as event insurance.

Contrarian angles: Consensus understates second-order effects—improved cash yields may fuel M&A and domestic capex rather than pure buybacks, compressing realized upside for passive long-only holders. Historical parallel: 2017 US tax cuts delivered front-loaded multiple expansion then mean reversion; monitor legislative catalysts and 2-quarter forward EPS revisions as primary stop/confirm signals.

Key Decisions for Investors

• Establish a 1.5% portfolio long in AAPL via Jan 2027 LEAP calls ~10–15% OTM (or equivalent equity) with a 12–24 month horizon; target +18–25% total return, stop-loss -10% absolute.
• Initiate a 1.0% long position in NKE equity, horizon 12 months; take profits if NKE outperforms the S&P 500 by +15% or on an earnings miss by >3% consensus.
• Implement a pair trade: Long AAPL (1.0%) / Short VGK (1.0%) to capture jurisdictional tax arbitrage; rebalance or close after 90 days or if the relative spread tightens to <1% on a 30-day basis.
• Buy downside protection: purchase 3–6 month VGK puts ~5% OTM sized to 0.5–1.0% of portfolio notional to hedge risk of a rapid ex-US re-rating; unwind if implied volatility falls >30%.
