Palladium has rallied approximately 90% from its 2025 lows near $1,300/oz to current levels around $2,500/oz, driven by supply concerns and broader PGMs market tightening. However, the rally is testing the tolerance of industrial consumers who have the technical capability to substitute palladium with platinum in catalytic converters. Above $2,500/oz, the economic incentive to switch intensifies significantly.
The substitution dynamic creates a de facto price ceiling for palladium. Auto catalyst manufacturers have already substituted 669,000 ounces of palladium with platinum in 2026, according to WPIC data. Each incremental $500/oz increase in palladium accelerates the substitution rate. At $2,500/oz versus platinum near $1,000/oz, the cost advantage of using platinum is overwhelming — approximately $1,500 per ounce savings for every ounce substituted.
The key question for the palladium market is whether supply-side constraints can sustain prices above the substitution threshold. The US anti-dumping duties on Russian palladium and South African supply constraints provide support, but they operate against a structural demand backdrop that is weakening due to EV adoption and substitution. The market's trajectory depends on which force dominates: supply scarcity or demand displacement.
