Copper Surge Reinforces BHP's Appeal, But Iron Ore and Jansen Risks Linger

What happened

Copper prices have surged on AI-driven demand and shifting trade policy, reinforcing BHP's copper-led investor appeal. BHP's copper segment indeed became the majority EBITDA contributor in the latest half (51% of Group Underlying EBITDA), with average realized copper price of $5.47/lb YTD FY26, up 31% YoY. However, BHP's earnings remain more sensitive to iron ore: FY2025 iron ore EBITDA was larger than copper, and profit sensitivity is $162M per $1/t iron ore versus $29M per 1¢/lb copper. Additionally, Jansen potash suffered a Stage 2 cost blowout to $6.9B and delay to late FY2031, triggering a ~$2.3B impairment and undermining capital allocation credibility. The stock has already rallied 80% over the past year to ~$85.8, trading at 20.5x P/E, embedding much of the copper optimism while leaving little margin of safety.

Implication

The copper demand story is real, but BHP's near-term earnings will still be iron ore driven, so any weakness in WAIO realized pricing or renewed China procurement frictions would hit the stock hard. Jansen's repeated cost and schedule resets increase the equity risk premium; investors should demand evidence of stabilization in the H2 FY2026 update before adding. The CEO transition on July 1, 2026 adds uncertainty about capital allocation priorities. If copper prices remain elevated and BHP delivers on iron ore pricing integrity and Jansen milestones, the stock could justify higher levels, but current valuation leaves little room for error. A wait-and-see approach is prudent, with catalysts over the next 6-12 months determining whether the copper narrative translates into durable earnings growth without iron ore or project setbacks.

Thesis delta

The new copper surge reinforces the copper-led narrative already priced into BHP, but does not alter valuation materially because iron ore sensitivity and Jansen execution risks remain unchanged. The thesis remains WAIT, with no change to the rating or price targets.
