Trump tariff shock triggers massive ASX wipeout—Top 20 stocks nosedive amid ETF bloodbath and mining meltdown

The Australian Securities Exchange (ASX) faced a wave of heavy losses on April 10, 2025, as a combination of sharp reversals in global equity sentiment, volatility in commodity-linked stocks, and policy uncertainty culminated in a dramatic selloff across sectors. Inverse ETFs, healthcare, and basic materials companies dominated the day’s list of worst performers, with investors rapidly unwinding bearish bets amid a backdrop of geopolitical trade recalibrations and central bank indecision.

Among the steepest decliners were the Betashares US Equities Strong Bear Currency Hedged Complex ETF (BBUS) and the Global X Ultra Short Nasdaq 100 Complex ETF (SNAS), each falling by nearly 25%. Their sudden downturn was driven by a U.S. stock market rally triggered by President Donald Trump’s decision to implement a temporary pause on most new tariffs—except for a 125% hike targeting Chinese imports. This policy maneuver blindsided investors who had bet on prolonged U.S. market weakness, catalyzing a rapid repositioning away from inverse products.

As U.S. indices surged—with the Nasdaq and S&P 500 each gaining over 5%—the ripple effect on Australian-listed inverse ETFs was immediate. BBUS dropped 24.81%, while SNAS declined 24.68%, making them the largest percentage losers of the day. These ETFs are designed to magnify daily negative returns of major U.S. indices and are often used by traders as short-term hedging instruments during periods of heightened risk. However, in a market environment where sentiment shifts quickly, inverse products can lead to significant losses when momentum turns.

How did sector-specific challenges impact healthcare and financial services stocks?

The fallout extended well beyond ETFs. The healthcare sector was one of the hardest hit, with Uscom Ltd (UCM) dropping 22.22%, Recce Pharmaceuticals Ltd (RCE) falling 9.23%, and Pacific Edge Ltd (PEB) sliding 12.50%. Investor anxiety was heightened following speculation that the U.S. administration could target imported pharmaceuticals as part of its broader trade agenda, creating uncertainty for Australian biotech firms that rely on global manufacturing, R&D partnerships, and cross-border licensing.

Healthcare stocks are often viewed as defensive in times of economic uncertainty. However, the nature of recent tariff threats has altered that calculus. For example, CSL—a heavyweight in the Australian healthcare landscape with extensive U.S. exposure—has already seen its valuation pressured by fears of supply chain disruptions and pricing controls. Although the day’s top losers were smaller-cap names, the broader sentiment weighed on the sector, with traders opting to de-risk portfolios ahead of potential policy escalation.

In financial services, Butn Ltd (BTN) and WT Financial Group Ltd (WTL) declined 13.04% and 11.54%, respectively. Their losses came despite relatively stable fundamentals, highlighting how market-wide sentiment, rather than company-specific news, drove the day’s trading action. Likewise, Complii Fintech Solutions Ltd (CF1) dropped 13.04%, reflecting broader pressure on speculative fintech names amid rising concerns around liquidity, valuations, and regulatory oversight in the wake of global rate uncertainty.

Are mining and energy stocks signaling deeper issues in commodity markets?

A notable trend on April 10 was the sharp decline in basic materials stocks, including explorers and junior producers already facing capital constraints and geopolitical exposure. Metal Bank Ltd (MBK) plunged 21.43%, Culpeo Minerals Ltd (CPO) dropped 15.39%, and OD6 Metals Ltd (OD6) declined 13.33%. Additionally, Panther Metals Ltd (PNT) lost 13.33%, and Stavely Minerals Ltd (SVY) fell 12.50%. These declines mirror investor concern that global supply chain pressures and falling commodity prices—partly influenced by weaker Chinese demand and U.S. tariff policies—could dampen future exploration and project development.

Minerals 260 Ltd (MI6), with a market capitalisation exceeding $237 million, fell 11.54% on heavy turnover. While larger than many of the microcaps on the list, MI6’s exposure to lithium and critical minerals may have made it more susceptible to bearish sentiment tied to China’s slowing industrial activity and fears of oversupply in the battery metals market.

Energy Metals Ltd (EME) declined 16.22%, reinforcing the trend that smaller-cap resource plays are highly vulnerable to external shocks. Broader uncertainty in energy markets, compounded by volatile uranium and rare earth pricing, is making investors more selective about risk exposure.

What broader economic and policy factors are weighing on Australian equities?

The sharp drawdown in ASX stocks occurred within a global context of renewed policy unpredictability. President Trump’s announcement of a 90-day pause on tariffs affecting most U.S. allies temporarily calmed global markets, but the dramatic escalation in duties against China revived fears of a prolonged trade conflict. Australia, with its heavy trade reliance on China and the broader Asia-Pacific region, stands at a critical intersection of these geopolitical fault lines.

Treasurer Jim Chalmers convened emergency meetings with financial regulators in response to the ASX’s estimated $112 billion loss in value since the start of April. Chalmers defended Australia’s underlying economic resilience but warned of volatility ahead. Opposition leaders, meanwhile, have seized on the downturn to challenge the government’s economic stewardship, framing it as a prelude to a broader recession—despite strong domestic labour figures and steady GDP growth in previous quarters.

Compounding the issue is the Reserve Bank of Australia’s reluctance to adjust interest rates in the face of market stress. While futures pricing suggests rising expectations for a rate cut, the RBA has deferred any policy shifts until May. Critics argue that the central bank’s inaction risks deepening investor pessimism and accelerating capital outflows, particularly as other major central banks begin signaling policy easing to support growth.

What role did consumer and tech names play in the April 10 selloff?

In addition to inverse ETFs and resource-linked stocks, consumer-facing companies and tech microcaps also struggled. Toys’R’US ANZ Ltd (TOY) dropped 9.09%, continuing a longer-term decline of 72.73% over the past year. Weak discretionary spending, cost inflation, and a tepid retail environment have weighed heavily on the brand’s ability to sustain momentum. Tinybeans Group Ltd (TNY) also declined 8.82%, reflecting investor caution around ad-based digital platforms during cyclical downturns in marketing spend.

The communication services and consumer cyclical sectors have remained especially vulnerable amid slowing household demand and tight margins. With inflation still above target and the cost of debt rising, companies in these segments face limited room to manoeuvre—a reality that is increasingly reflected in market valuations.

What can investors expect in the near term?

While the steep one-day losses across these 20 ASX stocks represent a sharp adjustment, analysts caution that the broader trend remains fluid. With global markets reacting to U.S. policy shifts, tariff escalations, and central bank posture, volatility is likely to persist in the coming weeks. Small-cap and microcap stocks, in particular, are expected to remain at heightened risk due to limited liquidity and susceptibility to macro headlines.

Nevertheless, some institutional investors suggest that this selloff may open selective opportunities. Value-oriented funds may look toward companies with solid balance sheets and exposure to defensible sectors such as domestic infrastructure, healthcare with low U.S. dependency, or dividend-paying financials. Others warn that the worst may not be over, as uncertainty around Chinese retaliation, supply chain disruptions, and RBA policy timing remains unresolved.

As the ASX continues to navigate a turbulent April, investors are increasingly focused on defensive repositioning and clarity on the policy front. The key question now is whether current volatility marks a short-term overreaction or the beginning of a more sustained downtrend driven by global economic realignment.
