The implementation of sweeping US tariffs in 2025 has created unprecedented disruption across global commodity markets, fundamentally reshaping trade flows and price dynamics worldwide. These trade measures, which include reciprocal tariffs of 10% on most countries, 25-50% tariffs on steel and aluminum, and 145% tariffs on China, have triggered complex ripple effects that extend far beyond simple import price increases.
Broad Economic Impact on Global Commodity Markets
The World Bank projects that commodity prices will fall by 12% in 2025 and another 5% in 2026, reaching their lowest levels in real terms since the early 2020s. This broad decline masks significant variations across different commodity categories, with some experiencing dramatic price increases while others face steep declines. Global trade flows have contracted by 5.5% to 8.5% relative to pre-tariff levels, depending on retaliation scenarios.
The IMF has noted that the effective US tariff rate reached 18.6% by August 2025, the highest since 1933, creating an average household income loss equivalent to $2,400 per year. This has contributed to a 1.8% increase in the overall US price level in the short term, with particular impacts on specific commodity sectors
Price Impact of US Tariffs on Major Commodity Categories
Agricultural Commodities: Trade Diversion and Market Realignment
Soybeans and Grain Markets
The tariff war has dramatically reshaped agricultural trade patterns, particularly for soybeans where the US and China are major players. US soybean exports to China have collapsed by approximately 90% due to prohibitive tariffs, forcing China to redirect purchases to Brazil and Argentina. Brazil's soybean exports to China would need to increase by almost 30% to compensate, requiring significant expansion in plantings and potentially diverting soybeans from domestic biodiesel production.
This trade diversion has created opportunities for South American producers while simultaneously putting pressure on US farmers. Brazilian and Argentine agricultural sectors are emerging as early winners, with escalating US-China tensions creating openings to ramp up exports of everything from meat to grains.
Fertilizer Price Surge
Agricultural input costs have risen sharply, with fertilizer prices becoming particularly problematic for farmers. The US imposed 25% tariffs on Canadian fertilizers in March 2025, affecting approximately 85% of US potash imports. Combined with elevated natural gas prices (a key input for nitrogen fertilizer production), farmers are facing what industry groups describe as "approaching disastrous levels" of fertilizer costs.
The National Corn Growers Association and 25 state corn grower groups have warned that the combination of low corn prices, trade uncertainty, and consistently high fertilizer costs have created a "calamitous environment for farmers". Nitrogen fertilizer prices are running 10-15% higher than last year's levels, far outpacing stagnant commodity prices.
Metal Markets: Direct Tariff Impact and Supply Chain Disruption
Steel and Aluminum
The most direct and severe impacts have been felt in metal markets, where the US imposed 25% tariffs in March 2025, later increased to 50% for most countries. The Midwest aluminum duty-paid premium reached 45 cents per pound (over $990/metric ton), marking a 70% increase since January 2025.
These tariffs have fundamentally altered pricing dynamics, with US prices for aluminum and steel becoming significantly higher than EU prices. The price difference increased by 77% for steel and 139% for aluminum between February and May 2025. The tariffs are estimated to add $50 billion in tariff costs, doubling the impact from the initial 25% rates.
Copper and Industrial Metals
Industrial metals have faced headwinds from both direct tariff threats and broader economic uncertainty. The Trump administration launched investigations into copper imports that could lead to additional tariffs, creating volatility in markets where 40% of refined copper demand and 70% of primary aluminum demand in the US is imported.
J.P. Morgan Research has turned bearish on base metals prices in the near term, citing "tariff-driven cuts to economic growth forecasts and an increased probability of recession". Copper prices fell 10% from March peaks due to concerns about real demand destruction and shaky investor sentiment.
Energy Markets: Demand Destruction and Geopolitical Risks
Oil Price Decline
Energy commodities have experienced significant downward pressure, with oil markets particularly affected by demand destruction fears. The IMF's World Economic Outlook noted that oil prices declined 9.7% between August 2024 and March 2025 as trade war fears, strong non-OPEC+ supply growth, and unwinding of production cuts created a bearish outlook.
Energy prices declined by an average of -13% in dollar terms during April 2025, as markets incorporated the effects of trade tensions and recession fears. The Energy Information Administration forecasts Brent crude will average $74/barrel in 2025, down from 2024 levels, and continue falling to $66/barrel in 2026.
Geopolitical Energy Security Concerns
The Middle East has emerged as a particular flashpoint, with geopolitical tensions contributing to energy price volatility. Threats of military intervention and potential disruption of the Strait of Hormuz (through which one-third of global seaborne crude oil passes) have created additional uncertainty. Qatar, the world's third-largest LNG exporter accounting for 20% of global trade, has taken precautionary measures by instructing vessels to wait outside the strait.
Precious Metals: Safe-Haven Surge
Precious metals have experienced dramatic price increases as investors seek safe-haven assets amid trade uncertainty. Gold futures hit record levels, reaching $3,534.10 per ounce in intraday trading, representing gains of about 30% in 2025 and nearly 40% from 12 months prior.
The surge has been driven by tariff-related hedging activity and uncertainty over trade policies. Silver prices have also experienced significant volatility, with reports of swings from $35/ounce to $28/ounce following tariff announcements. The imposition of duties on gold bars (including 1kg and 1oz bars) created additional market distortions in what was previously considered one of the "cleanest, most efficient and most trusted" markets in global finance.
Critical Materials and Strategic Resources
Rare Earth Elements
China's retaliation has been particularly severe in the critical materials sector, where it placed export restrictions on seven types of rare earth elements including neodymium, terbium, dysprosium, and yttrium-related substances. This affects the global supply of materials essential for everything from smartphones to electric vehicle batteries, as China controls approximately 90% of global refined rare earth supply.
The restrictions represent China's capability to leverage its dominance in mining and processing these vital minerals, potentially cutting off US access to materials crucial for defense, electric vehicles, renewable energy, and electronics sectors. This has spurred Western efforts to establish alternative supply chains, though these remain in early stages.
Supply Chain Resilience Challenges
The tariff regime has exposed vulnerabilities in global supply chains for critical materials. The US remains over 50% import-reliant on forty of fifty designated critical minerals, with China dominating many supply chains from extraction to processing. While the administration has launched Section 232 investigations into critical mineral imports, experts emphasize that optimal results require "a scalpel, not a chainsaw" approach to tariff implementation.
Regional Winners and Losers
South American Beneficiaries
Brazil and Argentina have emerged as clear winners in several commodity sectors. Brazil's beef exports have expanded into new markets as US tariffs on major beef buyers created opportunities, with Japan (America's second-largest beef client) in advanced talks to start buying cheaper Brazilian meat.
The countries are capitalizing on China's shift away from US agricultural products, with Brazil receiving large soybean orders and Argentina restarting poultry shipments to China. However, experts warn that increasing bilateral barriers primarily alter "who sells to whom" rather than enhancing financial returns, as prices remain determined by global factors.
Global Economic Consequences
The International Food Policy Research Institute (IFPRI) estimates that tariffs could lead to a contraction in global agricultural trade of 3.3%-4.7% and a decline in global GDP of 0.3%-0.4%, with US GDP falling further by 1%-1.2% depending on retaliation scenarios.
The World Trade Organization has warned that global merchandise trade volume is projected to decline by 0.2% in 2025 under current conditions, nearly three percentage points lower than baseline projections assuming low tariffs. This could worsen to a 1.5% contraction if trade tensions escalate further.
Long-term Market Structure Changes
The tariff regime is creating permanent shifts in global commodity trade patterns. US imports from China have collapsed by 90% across most scenarios, while Chinese exports are being redirected toward other destinations including the European Union, UK, and Latin America. This trade diversion is facilitated through complex routing mechanisms, with more than half of Chinese value-added reaching the US via Mexico in some scenarios.
These changes represent what experts describe as a "permanent loss of market share" for the US, especially in key markets like China. As countries in the Southern Hemisphere forge deeper trade ties with major importing nations, the US faces long-term challenges in reclaiming its former position in global agricultural and commodity markets.
