Analysis
BHP was exposed to significant volatility following the introduction of the "Liberation Day" tariffs in April 2025, which initially drove U.S. tariffs to their highest levels since the 1930s. The immediate impact was characterized by substantial price momentum and the front-loading of demand as customers sought to secure supply ahead of the new trade barriers. In the copper market, this created a significant premium for U.S.-based COMEX prices over the London Metals Exchange, incentivizing global cathode shipments to the United States.
The direct financial impact on BHP was largely mitigated by subsequent policy adjustments and exemptions. The U.S. government eventually excluded copper cathode from the reciprocal tariff list, which effectively closed the price differential between regional exchanges and prevented a direct cost headwind on BHP’s primary copper exports. By the end of 2025, the company reported that demand had slowed as the effects of earlier front-loading waned, resulting in a normalization of trade flows.
Despite the period of extreme policy uncertainty, BHP reported a record half-year for its copper business in 1H FY2026. The "threat of tariffs" and associated price volatility actually contributed to record copper prices during the period, providing a favorable $2.1B EBITDA tailwind from higher realized prices in copper, gold, and silver. Management maintained that the company's commodities—particularly copper, iron ore, and potash—are resilient to diverse trade scenarios due to their critical role in global infrastructure and the energy transition.
BHP’s geographic and commodity diversification served as a primary mitigation strategy. While the U.S. trade policy remained volatile throughout 2025, BHP observed resilient demand in other key markets, including China and India. The company noted that "more favorable trade outcomes than expected" had supported healthy commodity demand through the end of the 2025 calendar year, allowing the group to capture high margins despite the broader geopolitical backdrop.

This has taken a marked step up in recent months, and we're seeing U.S. tariffs higher now than they've been since the 1930s. That has pretty significant implications for the global economy.
Our strong operational performance is reflected in our healthy set of financial results... This enabled us to fully capture the benefit of higher copper, gold, and iron ore prices.
Commodities saw healthy demand in 2025, supported by more favorable trade outcomes than expected, supportive policy, and improved confidence.
