What was said:
The strategic objectives of the US-Israel-Iran conflict remain unclear, leaving markets facing a longer uncertainty window rather than a single geopolitical shock. With shipping through the Strait of Hormuz coming close to a standstill last week and oil infrastructure strikes over the weekend, crude is moving sharply higher, with Brent surging towards some Wall Street estimates of $120.
Several structural dynamics are emerging. China and India are increasing purchases of Russian oil. Every barrel of oil sold by Russia helps fund its war with Ukraine and places further pressure on Europe to accelerate defence spending, strengthen critical infrastructure and re-shore energy dependency.
As defence spending accelerates, supply chains for defence inputs are tightening. Tungsten – critical for modern munitions – contains roughly 15–25% content in tank rounds, 30–60% in armour-piercing rifle bullets and 5–15% in missile fragments. China controls around 80% of global tungsten supply, while Chinese tungsten exports fell roughly 70% last year, tightening availability just as Western defence stockpiles depleted in Ukraine and the Middle East need replenishing.
Helium supply is another unexpected victim of the Middle East conflict. Qatar's production halt at Ras Laffan following Iranian strikes has removed roughly 30% of global supply from the market. Helium shortages historically last 2–3 years because the gas is difficult to store and relies on scarce iso-containers that take 20 months to build. Meanwhile, demand is rising from multiple directions: a single Falcon 9 launch consumes 14–18% of global daily helium output, AI semiconductor fabrication requires helium for wafer cooling, and healthcare accounts for 20% of demand through MRI machines operating at -269°C.
Why we give a ****:
This conflict is reinforcing structural investment themes, not just creating a short-term trade.
First, defence supply chains are tightening as munitions are consumed faster than they can be replaced. Materials like tungsten are becoming strategically important as Western governments try to reduce reliance on Chinese supply.
Second, energy and industrial gases are proving fragile. With roughly 30% of global helium supply temporarily offline and shortages historically lasting 2–3 years, sectors ranging from space launches to semiconductor fabrication and healthcare face supply constraints.
Alongside industrial gases, oil has also become the key transmission mechanism of the conflict. Brent surged toward $120 as shipping through the Strait of Hormuz effectively halted, highlighting how quickly geopolitical shocks can threaten energy security and create inflation pressure across the global economy.
Beyond the immediate price spike, years of underinvestment in oil supply and damage to regional infrastructure are strengthening the case for a multi-year upcycle in oil field services, as facilities across the Middle East will inevitably need repairing or rebuilding once stability returns.
The broader takeaway is that defence inputs, strategic materials and energy infrastructure are increasingly being treated by markets as structural sectors rather than cyclical ones.

📚 Oil Spikes as Gulf Supply Risk Emerges
Why Read? Oil surged above $93 – the highest level in more than two years – after Qatar warned Gulf producers could halt exports within days if the conflict continues. With LNG output already disrupted and shipping through the Strait of Hormuz slowing sharply, markets are beginning to price a real supply shock. If disruption persists, analysts warn crude could push toward $100–150, raising inflation risks and tightening global economic conditions. Read here.
Stock Of The Week
Nuclear Fuel Supply Chain Play
ASP Isotopes is building an advanced isotope enrichment platform targeting nuclear medicine, semiconductors and next-generation nuclear fuels, positioning the company at the centre of the emerging supply chain for advanced reactors.
The latest catalyst is the signing of an MOU by its subsidiary Quantum Leap Energy with a major US nuclear power operator to explore supporting domestic production of HALEU and LEU+, fuels critical for small modular and next-generation reactors. With Russian uranium imports banned from 2028 and demand for advanced nuclear fuel rising, US-based enrichment capacity is becoming strategically important.
ASP Isotopes also owns one of the few new large-scale helium developments globally, linked to the Renergen project in South Africa with >3% helium concentrations (10x the global average) and the potential to supply ~7% of global production once Phase 2 completes, offering rare non-OPEC, non-Chinese supply into a market where scarcity is structural, not cyclical.
