A single export restriction can spike prices worldwide. A single chip bottleneck can idle factories across continents. That’s not bad luck, it’s the architecture of the modern economy and it’s why I keep coming back to one idea: the commanding heights.

I walk through what commanding heights mean in 2026 terms, where power sits in semiconductors, cloud computing and AI infrastructure, telecom networks, critical minerals, battery supply chains, electricity grids, logistics corridors, biomanufacturing, and cybersecurity. These aren’t just “important industries.” They’re the choke points where a failure doesn’t stay contained, it cascades across products, markets, and national security. You’ll hear why concentration in one firm, one region, or one processing step turns ordinary sourcing into a strategic vulnerability.

China is the clearest case study. I break down how decades of deliberate choices helped it secure leverage in rare earth processing and other critical inputs, how that plays into wider trade and industrial policy, and how three phases of development moved from heavy industry to global manufacturing integration and then into 21st century commanding heights like EVs, solar PV, robotics, semiconductors, AI, and digital infrastructure. I also connect the dots to today’s policy response, from the US Chips and Science Act to the EU Critical Raw Materials Act, and what “de-risking” really looks like in practice.

You’ll leave with concrete moves to make now: map beyond tier one, identify single points of failure, stress test geopolitical exposure, diversify with multisourcing and friendshoring where it fits, build strategic inventory for high-impact items, and invest in supply chain intelligence as a continuous capability. If this helped sharpen your thinking, subscribe, share the episode with a colleague, and leave a review so more supply chain leaders can find it.

About Tony Hines and the Chain Reaction Podcast – All About Supply Chain Advantage
I have been researching and writing about supply chains for over 25 years. I wrote my first book on supply chain strategies in the early 2000s. The latest edition is published in 2024 available from Routledge, Amazon and all good book stores. Each week we have special episodes on particular topics relating to supply chains. We have a weekly news round up every Saturday at 12 noon. ...
