BHP Shares Decline on Port Hedland Strike and Lowered Copper Guidance

BHP Group shares fell 2.9% to A$58.795 on Thursday, pressured by news of significant industrial action at its main iron ore export terminal and a mixed quarterly production update that included a weaker forecast for copper.

Port Hedland Strike Disrupts Exports

BHP is facing its first major industrial action in more than 20 years at its Port Hedland iron ore facility in Western Australia. The strike involves approximately 160 to 200 port and maintenance workers after six months of negotiations over a new four-year enterprise agreement stalled.

The stoppage, organized by the Combined BHP Ports Unions, began after a final bargaining session on July 14 failed to produce an agreement. The financial impact could be significant, as Port Hedland handles an estimated $80 million worth of BHP's iron ore exports each day. Talks are not scheduled to resume until July 21, according to the report.

Production Report Disappoints

Compounding the labor issues, BHP released a mixed Q4 FY2026 production report. While Western Australian iron ore output rose 7% quarter-on-quarter, it marked a 3% decline from the same period last year.

More critically for investors, the company lowered its copper production guidance for fiscal year 2027. This news soured sentiment among investors already concerned about the company's cost pressures, including a previously announced budget increase for its Jansen Stage 2 potash project.

Market Context

Despite the day's decline, BHP's stock has been a strong performer in 2026, gaining nearly 30% year-to-date on the back of rising commodity prices for copper and iron ore. Shares had risen almost 3% in the days leading up to the production report, suggesting some investors were anticipating a more positive update.
