US-China Tension Fuels Decoupling in Tech Research, Study Shows

The Australian Strategic Policy Institute's Critical Technology Tracker, which analyzed over 7 million papers across 74 critical fields, reports US‑China collaboration in technology research has fallen to its lowest level in 20 years: only about 25% of China’s collaborations now involve American researchers and collaboration intensity has reverted to 2005 levels. The drop, attributed to rising US‑China tensions, poses medium‑term strategic risks to global innovation ecosystems and could materially affect firms and sectors exposed to technology, defense and cross‑border supply‑chain interdependence.

Analysis

Market structure: The ASPI finding (US co-authorship in China research down to ~25% from >50% five years ago, intensity back to 2005) implies a bifurcated R&D ecosystem and duplicated capex. Winners: US/EU defense primes (LMT, NOC, RTX) and non-Chinese semicap leaders (ASML, LRCX, AMAT) as allied reshoring and security procurement rise; losers: firms with concentrated China revenue/exposure and globalized research models (some Big Tech R&D outposts, Chinese incumbents reliant on foreign partnerships). Expect 3–8% incremental annual capex in allied semiconductor and rare-earth supply chains over 12–36 months.

Risk assessment: Tail risks include rapid escalation of export controls or Chinese countermeasures (rare-earth export restrictions, financial sanctions) that could spike input costs and disrupt supply globally; probability of such a shock in next 12 months ~10–20%. Short-term (days–weeks) markets will trade headlines; medium-term (3–12 months) fundamentals shift as CHIPS/defense budgets flow; long-term (12–36 months) we may see structural duplication and higher unit costs. Hidden dependencies: graduate student flows, cross-border IP licensing, and foundry capacity allocation — any migration of talent or forced IP localization materially alters revenue mixes.

Trade implications: Tactical plays favor 6–18 month exposure to defense primes (buy call spreads on LMT/NOC) and commodity/rare-earth miners (MP Materials), and selective semicap longs (ASML, LRCX) funded by shorts of China-tech growth proxies (KWEB) or reduction/hedge of TSM. Use options to cap cost: 3–9 month call spreads on LMT/ASML and 6–12 month put spreads on TSM or KWEB to express downside if export curbs expand. Rebalance as legislative catalysts (CHIPS II, export-control updates) occur.

Contrarian angles: Markets assume permanent bifurcation; overlooked is China’s likely push to oversupply domestically leading to downward price pressure on tools and wafer demand beyond year three, which could compress semicap margins — a reason not to overpay for perpetual-growth multiples. Conversely, US incumbents with >30% China revenue may be oversold near-term; selective buys on 20–40% pullbacks could pay off if diplomatic thawing or carve-outs occur. Historical analog: Cold-War tech bifurcation created both duplication and long-term dominance by agile private-sector hubs, so watch talent and IP mobility closely.

Key Decisions for Investors

• Establish a 2–3% portfolio long in Lockheed Martin (LMT) via a 6–12 month call spread (buy ATM call, sell 25% OTM call) to capture expected 5–12% revenue tail from defense spending; take profits at +30% or re-evaluate after 12 months or if Congress fails to pass budget increases.
• Add 1–2% long in MP Materials (MP) for 12–36 months to hedge rare-earth supply risk, increasing position by another 1% on any drawdown >15%; target +20–50% upside if China limits exports or Western onshoring accelerates.
• Implement a relative-value pair: long 1.5% combined ASML (ASML) + LAM Research (LRCX) exposure and short 1–1.5% KWEB (China internet/AI ETF) for 6–18 months to express tech bloc bifurcation; use 3–6 month option collars to limit downside if volatility spikes >30% intraperiod.
• Hedge Taiwan/China semiconductor tail risk by reducing TSM (TSM) exposure by 20% if current weight >3% or buying a 6–12 month put spread (~5–15% OTM) costing <2% of portfolio to protect against export-control-driven revenue drops over the next year.
