America’s fiscal problem has a sourced starting point. In its February 2026 baseline, the Congressional Budget Office projected a US$1.9 trillion fiscal-year 2026 deficit and public debt of 120% of GDP by 2036. These are conditional projections under that baseline, not final fiscal-year accounts or a forecast of next week’s bond auction.
This is scenario analysis, not a prediction of an inevitable crash. Yields need not rise in a straight line, and government spending is not the only possible explanation for their movement. We are asking how a selloff could reach the mine gate.
Analysis: three selloffs hiding in one headline
Start with why yields are rising. A bond market responding to stronger growth is a different problem from one losing confidence in the fiscal arithmetic. The headline can look much the same. The commodity consequences need not.
| Hypothetical trigger | Commodity transmission to test | Evidence that would challenge the scenario |
|---|---|---|
| Stronger real growth | Better physical demand could offset dearer finance | Weak orders and rising inventories |
| Inflation or fiscal-risk repricing | Input costs and discount rates could rise together | Stable inflation expectations and contained credit spreads |
| Funding stress followed by recession fears | Forced selling could precede weaker end demand | Order books holding up and financing reopening |
These are possible mechanisms, not forecasts or estimated price moves. Several can operate together. The market’s first reaction need not match the eventual effect on physical consumption.
The ten-year story meets next quarter’s order book
Our expectation is that copper, nickel and other industrial exposures would be vulnerable if manufacturing and construction weaken too. A ten-year demand story is useful. It is less useful to the buyer who has just cancelled next quarter’s order.
But a supply disruption could offset that weakness. An investor who only watches the equity index could miss a tightening physical market. Read inventories and delivery premiums alongside purchasing activity and mine disruptions. One indicator should not get the whole committee’s voting rights.
Gold needs its own test. We think rising inflation-adjusted yields and a firmer dollar can challenge the monetary-metal case, while a loss of confidence in policy could support it. During funding stress, we would allow for gold being sold to raise cash before assuming it provides shelter. Gold-mining shares add operating and financing risks on top of the metal exposure.
Start with the bills
Consider a deliberately hypothetical mine with revenue of 100 and cash operating costs of 70 per unit sold. Its operating margin is 30. If its realised price falls 20% while those costs stay fixed, the margin becomes 10: a two-thirds decline before interest, tax, sustaining capital or hedging. This is arithmetic, not a company estimate.
Start with cash, debt maturities, covenants, committed capital spending and hedge terms. The deposit does not get smaller when credit tightens. The financing problem can get considerably larger. A developer waiting for finance could face a different problem from a cash-funded producer, even with the same commodity exposure.
The honest bull case
Fiscal spending can support real demand if it builds infrastructure that consumes material. Lower exchange rates in a producer’s home currency could also cushion local costs, although that depends on the cost mix and hedges. Strong physical demand would weaken our bearish scenario.
The Take: the long-term shortage thesis cannot pay a short-term refinancing bill. Test which businesses can fund themselves through the shock. A good commodity argument needs a company that can afford to wait.
