Physical reality constrains digital ambition. That gap is the investment thesis. The Chokepoint on Substack.

Most investors approach critical minerals the wrong way. They focus on the resource. The returns don't come from the rock.

@sciam 850 Tomahawks in four weeks - nine times annual procurement. American Tungsten targeting 8% of US demand by 2027. DFARS requires defense procurement free of Chinese tungsten by January 1, 2027. The mine timeline and the compliance deadline are on different clocks.

@TheEconomist The reserves aren't a solution - they're a timeline. SPR at 40-year lows. Commercial stocks approaching critical levels by August per the EIA. The calm price is the mechanism by which the buffer ends, not evidence the shock is fading.

@JavierBlas Blas identifies it himself: the oversupply is spent, the SPR is at 40-year lows, the jawboning requires a willing audience. These aren't reasons prices are low. They're the mechanisms by which the buffer ends.

@anasalhajji Pre-shale, Cushing was a domestic signal. Post-Hormuz, US net exports hit a record 5.8 million barrels per day. The US became the marginal supplier to international markets. The crisis restored the relevance.

@mining Europe became innovative in technologies that use critical materials. China became innovative in technologies that control them. The funding filters did the rest.

@DrJPPham @Samsung @TaiwanSemi_TSC @SKhynix Kanto Denka and Central Glass just made the supply tighter permanently. Both notified Samsung, SK Hynix, and TSMC this week - halting WF6 production July 1. No alternative source found after five months of drawdown. Japan's 25% of global supply isn't coming back.

@kyleichan China developing rare-earth-free magnets while holding the processing monopoly on every alternative is the long game. The export controls buy time. The technology development buys the exit. The rest of the world gets neither on the same timeline.

@ColumbiaUEnergy The lanthanum dependency is one most analysis skips. At $1/kg, separation outside China is uneconomical - economics actively maintains the dependency. The magnet headline gets attention. The jet fuel catalyst has no obvious fix.

@derrick_dao An embargo written as a licensing regime' is the right framing. Yttrium to the US down 95% while Europe restocks at 44% of total exports. The legal architecture gives China deniability. The trade data tells the actual story.
