The constraint behind
the constraint behind the headline.

Mexel maps the hidden physical, chemical, and process bottlenecks that geopolitical events activate — tracing the full transmission chain from obscure chokepoint to sector implication to decision signal. For investors, corporates, and analysts who see one layer deeper.

TODAY'S DECISION LAYER

What matters now.

Mexel Insights · Q2 2026 assessment
What changed
China expanded export controls to include antimony, tungsten, and tellurium — following the 2023 gallium/germanium restrictions. Five of the top six semiconductor-grade minerals now face Chinese licensing requirements.
Why it matters
Western supply chains for defence, semiconductors, and solar face simultaneous chokepoints. No credible alternative supply exists at scale for 3-5 years. Procurement teams without hedged positions are exposed.
Best relative expressions
Uranium/nuclear (data centre power demand), copper miners (structural deficit), Australian REE processors (diversification beneficiary), green ammonia (IMO 2030 marine transition).
Most pressured expressions
GaN/GaAs chip fabs (gallium controls), CdTe solar manufacturers (tellurium squeeze), EU importers in CBAM scope (Q3 2026 deadline), DRC-exposed battery supply chains (ESG + cobalt).
Key trigger to watch
CBAM Phase-in enforcement begins Q3 2026. 49,000 companies entering CSRD Wave 2 disclosure scope. If enforcement is strict, expect repricing across steel, aluminium, and fertiliser import chains into Europe.
What would prove this wrong
China reverses or softens export licensing (low probability). Major non-Chinese gallium/germanium capacity comes online (18+ month lead time). CBAM enforcement is delayed beyond 2027. US-China diplomatic reset reduces mineral weaponisation.
