On September 14, BHP Billiton fell 3.02% in pre-market trading, trading at $84.43/share, with turnover of $583,800. The decline extends a multi-session selloff across diversified metals and mining stocks driven by persistent uncertainty over U.S. copper tariff policy.

Reports indicated that the White House has not yet decided whether to impose tariffs on refined copper, as the administration weighs the benefits of supporting domestic copper production against the risk of raising manufacturing costs and consumer prices. The unresolved policy stance has triggered sharp drops in international copper prices, with LME copper futures falling over 3% and COMEX copper futures dropping more than 4% in recent sessions, pressuring copper-exposed producers broadly.

Within the Diversified Metals and Mining sector, the overall tone remained weak. Among peers, Rio Tinto fell 2.96%, Teck Resources fell 3.16%, USA Rare Earth fell 2.51%, and MP Materials fell 1.01%. BHP Billiton, which derived 54% of group EBITDA from copper in its latest fiscal year, remains particularly sensitive to copper price swings and tariff-related policy shifts.
