Trump’s Trade Threats: What ASX Investors Should Watch Across Sectors

Ujjwal Maheshwari Ujjwal Maheshwari, July 16, 2025

As trade tensions flare under Donald Trump’s leadership, the global economic landscape is once again facing turmoil. This time, Trump’s rhetoric has brought forward threats of higher tariffs on various imports, including pharmaceutical products and copper. While these threats may seem distant to Australian investors, the potential impacts are significant and should not be underestimated. Australian companies, particularly in sectors such as pharmaceuticals, biotech, and mining, may find themselves caught in the crossfire of an escalating trade war.

The Australian Stock Exchange (ASX) has already started pricing in these early risks, but what does this mean for investors in the coming months? As Trump’s trade war 2.0 takes shape, understanding the key sectors at risk and identifying potential opportunities will be crucial for any ASX investor.

 

Trump’s Pharma Tariffs: Risk and Opportunity for CSL and Aussie Biotechs

Main Issue: Trump’s Proposed 200% Tariff on Drug Imports

One of the most significant threats posed by Trump’s proposed tariffs is the potential for 200% tariffs on pharmaceutical imports. The proposal aims to increase the cost of importing drugs from foreign markets, particularly targeting countries that heavily regulate or subsidise drug prices, potentially including Australia. For Australian pharmaceutical companies, this could translate into higher production costs and decreased profit margins, especially for those reliant on US sales.

Trump’s stance on drug pricing, coupled with his criticism of subsidised systems like Australia’s Pharmaceutical Benefits Scheme (PBS), places Australian companies at the forefront of this looming crisis. While US-based drug manufacturers may be less affected due to their internal manufacturing capabilities, Australia’s reliance on global supply chains makes it vulnerable to the proposed changes.

CSL’s Position and Lobbying Efforts

CSL Ltd (ASX: CSL), one of Australia’s largest and most successful pharmaceutical companies, has been particularly vocal in opposing these proposed tariffs. The company’s operations in the US are extensive, with CSL Plasma and its flu treatments representing crucial revenue streams. A proposed 200% tariff could significantly impact CSL’s bottom line, as the US is a major market for CSL’s products.

In response, CSL has ramped up its lobbying efforts, working closely with policymakers to minimise the potential impact of the proposed tariffs. The company has consistently highlighted the risks to patient care and the long-term consequences for both businesses and consumers. However, even if CSL successfully mitigates some of these tariffs through lobbying, broader pressures on drug pricing and the potential for price renegotiations could still pose challenges to profitability.

Impact on Other Biotech Stocks

While CSL is at the forefront of these discussions, other Australian biotech companies could also feel the pinch. Companies such as Cochlear Ltd (ASX: COH) and ResMed Inc. (ASX: RMD), heavily dependent on US sales, may face similar hurdles. Cochlear, for example, faces pricing pressures on its hearing devices, while ResMed’s sleep apnea treatments could become more expensive for US customers.

For investors, this presents both risks and opportunities. If proposed tariff threats materialise, margin compression, slower revenue growth, and price renegotiations with US customers could follow. However, some biotech companies might benefit from increased demand for locally produced goods as American manufacturers ramp up production.

 

Copper Tariffs and the ASX Mining Sector: Winners and Losers

Main Issue: Trump’s Proposed 50% Tariff on Copper Imports to the US

Trump’s proposed 50% tariff on copper imports to the US has created significant uncertainty in the global copper market. As one of the world’s largest consumers of copper, the US move could disrupt global supply chains, leading to price volatility impacting Australian miners. For ASX investors, understanding the potential risks and rewards in the copper sector is key.

This bold move aims to reduce the US’s dependence on foreign copper and bolster domestic production but could be a double-edged sword. Copper prices may rise globally due to reduced supply from major producers, especially in Latin America, where countries like Chile dominate copper production. Conversely, higher copper prices could hurt US industries reliant on copper, from construction to electrical manufacturing.

For Australia, the major concern revolves around impacts on our copper exporters. While Australian copper miners are somewhat insulated from direct tariffs, the ripple effects of price volatility remain challenging. However, for some companies, surging copper prices could provide a welcome windfall, especially those with significant copper operations.

BHP’s Strategic Position: No Direct Exposure, But Potential Upside

BHP (ASX: BHP), one of the world’s largest mining companies, finds itself in a relatively strong position amid this proposed copper tariff situation. Although BHP operates the Escondida copper project in Chile, its primary focus on the Asian market—particularly China—means less direct exposure to US tariffs. This factor is critical as China remains the world’s largest consumer of copper, with strong future demand anticipated from renewable energy and electric vehicles, both copper-intensive sectors.

Interestingly, BHP’s Resolution Mine project in Arizona could potentially benefit if US-based copper producers ramp up production to reduce import reliance. As a result, the Resolution Mine, being US-based, could become more valuable, providing BHP with a strategic edge despite limited direct tariff exposure.

Other ASX Miners: Risk and Opportunity

While BHP may be somewhat insulated from the immediate impacts of the proposed copper tariff, other ASX-listed miners could experience both risks and opportunities. For example, Rio Tinto (ASX: RIO) and Sandfire Resources (ASX: SFR) are more exposed to the global copper market, and the proposed tariff could lead to a price surge, benefiting them in the short term.

Rio Tinto (ASX: RIO), a global giant with significant copper operations, could see its copper projects become more profitable as a result of rising global copper prices. With projects in both North and South America, Rio Tinto is well-positioned to capitalise on price increases from global supply shortages.

Sandfire Resources (ASX: SFR), a smaller player in the copper space but one that has been making strides with its DeGrussa Copper-Gold Mine in Western Australia, stands to benefit from higher copper prices. As copper becomes scarcer on the global market, companies like Sandfire, which are able to produce copper at a competitive cost, could enjoy significant price premiums.

BHP’s acquisition of OZ Minerals has further strengthened its position in Australia’s copper sector. With the addition of the Prominent Hill and Carrapateena copper-gold projects in South Australia, the company may see increased investor interest if copper prices spike. However, it’s important for investors to keep an eye on potential cost pressures in the longer term, especially if the US tariff causes global trade to slow down and affects demand.

For ASX investors, the key takeaway here is that while there are significant risks involved, especially with regard to price volatility and the impact of proposed tariffs, there are also opportunities. Companies that can navigate these challenges effectively, such as BHP, Rio Tinto, Sandfire, and OZ Minerals, stand to benefit from higher copper prices or strategic positioning in response to shifting global demand.

 

Broader Market Risks: How Trump’s Trade War Could Affect ASX Sentiment

Trump’s trade war threatens significant uncertainty, not only in specific industries but also broader market sentiment. As proposed tariffs rise, particularly against China, ripple effects could impact sectors from mining to agriculture, causing volatility on the ASX.

AUD/USD Volatility and Trade Sentiment

One subtle but important impact of Trump’s trade threats could be felt in currency markets. Rising trade tensions often result in a weaker Australian Dollar (AUD), affecting ASX stocks with significant international exposure. While some sectors, such as tourism and education, could benefit from a weaker AUD, export-dependent stocks might face margin pressures.

Impact on Commodity-Linked Stocks

Australia’s mining sector is highly exposed to global trade dynamics. If the trade war slows global growth, demand for key commodities like iron ore, coal, copper, and lithium could fall, affecting prices. For example, China’s demand for Australian iron ore could diminish, impacting companies like BHP (ASX: BHP), Rio Tinto (ASX: RIO), and Fortescue Metals (ASX: FMG).
However, if trade disruptions create a supply shortage, global commodity prices could rise, benefiting Australian miners. Investors need to balance short-term risks with long-term opportunities from rising commodity prices.

Asia-Facing Stocks: Fortescue, Treasury Wine, and Supply Chain Fears

Companies with significant exposure to Asia, such as Fortescue Metals and Treasury Wine Estates (ASX: TWE), could face risks if the trade war escalates. Fortescue, dependent on China’s iron ore demand, might experience volatility if China imposes tariffs or if demand drops. Similarly, Treasury Wine, heavily reliant on Chinese wine sales, could see sharp declines in revenue from a trade dispute.
Supply chain disruptions are another risk, with potential delays, higher shipping costs, and customs hold-ups impacting companies that depend on smooth logistics for imports and exports. ASX investors should closely watch how these disruptions affect Asia-facing companies.

 

Key Dates and Catalysts: What to Watch for ASX Investors

August – Key Deadline for Pharmaceutical Tariffs

August is shaping up to be a key month for tariff announcements, although the proposed 200% pharmaceutical tariffs are still under review and may include a grace period before enforcement. Companies like CSL Ltd (ASX: CSL), which have significant exposure to the US market, could see higher production costs and reduced demand for key drugs. While CSL is actively lobbying to minimise the impact, the broader sector could face margin compression. Monitoring any policy shifts or exemptions granted to Australian firms will be important for investors, especially in the biotech and pharmaceutical sectors.

US Election Campaigns and Trade Policy Shifts

The 2024 US presidential election could lead to significant changes in trade policy, depending on who wins. If Trump stays in office, we can expect more tariffs, especially targeting China and potentially Australia. A change in leadership could shift US trade strategies, affecting sectors like mining, pharmaceuticals, and agriculture. Investors should track campaign promises related to trade, as these will influence market sentiment and sector performance in the coming months.

China’s Response: A Wildcard for ASX Investors

China’s response to Trump’s trade policies is another wildcard for ASX investors. Retaliatory tariffs on Australian exports, especially iron ore and wine, could affect companies like Fortescue Metals (ASX: FMG) and Treasury Wine Estates (ASX: TWE). Any shift in China’s trade stance, whether through easing tariffs or new trade agreements, could provide opportunities for Australian exporters, making it critical to monitor China-US trade relations.

 

Investor Outlook: Actionable Takeaways for ASX Investors

Stock-Specific Exposure: Monitor CSL’s US revenue share and lobbying efforts as it faces potential price pressure from drug tariffs. Keep an eye on Cochlear and ResMed for potential margin compression.
Commodity Pricing Trends: Watch for potential copper price hikes and their impact on mining stocks, especially Rio Tinto, Sandfire, and OZ Minerals.
Policy Timing and Exemptions: Stay alert to announcements regarding tariff exemptions for Australia or specific sectors, particularly pharmaceuticals and mining.
Broad Sentiment Risk: Watch for shifts in AUD/USD and broader risk sentiment that could affect Asia-facing exporters like Fortescue Metals and Treasury Wine Estates.

 

Conclusion – The Potential Impact of Trump’s Tariffs on the ASX Landscape

Trump’s trade threats are set to shake the ASX, with specific sectors standing to gain or lose significantly depending on the outcome of the trade war. Pharmaceutical, biotech, and mining stocks are most at risk, with some companies positioned to benefit from higher commodity prices or political intervention. For investors, staying informed on the timing of tariff implementation, trade policy shifts, and China’s response will be key to navigating the evolving landscape.
By keeping a close watch on these sectors and aligning your investment strategy with the potential risks and rewards, you can position yourself for success as global trade dynamics continue to evolve.
