S&P GSCI to S&P 500 Ratio Hits 50-Year Low as Physical Commodity Scarcity Signals Intensify
Commodity-to-equity valuation has compressed to extremes not seen since prior cycles of scarcity. State export controls and chronic underinvestment create a supply response lag measured in years. Capital rotation or policy adjustment will determine whether the reversion occurs through price or quantity adjustments.
Next steps hinge on whether central bank or treasury actions address the trade deficit and resource access. Sustained ratio compression below current levels would require either rapid new mine supply or demand destruction, neither of which appears in current project pipelines or policy calendars.
