Global commodity supply chains are navigating acute physical tightness, political intervention, and shifting trade routes. From inventory squeezes in industrial metals to geopolitical friction across energy and agricultural markets, foundational trade flows are undergoing substantial realignments.
Freight & Shipping: Indonesian Aluminium Surge and Argentine Normalization
Southeast Asian dry freight and industrial metal corridors saw dramatic volume gains in mid-2026. Indonesian exports of primary and unwrought alloyed aluminium surged 127% year-over-year in June, reaching 105,619 metric tons. For the first half of the year, total Indonesian aluminium exports reached 421,390 tons—a 63% annual increase—with primary destinations including Vietnam, China, and South Korea. Notably, PT Alamtri Resources Indonesia dispatched its initial export shipments directly to the United States and South Korea, signaling an expansion of regional refining output into transatlantic routes.
By contrast, South American agricultural shipping experienced a pronounced slowdown. Argentina’s agricultural export revenues fell 28% year-over-year in July to $2.918 billion. Industry chamber CIARA-CEC attributed the drop to market normalization following the expiration of temporary export duty cuts that inflated July 2025 sales, marking a return to baseline seasonal shipping patterns.
Agriculture: Chinese Buyers Capitalize on Price Dips Amid US Midwest Heat
Agricultural trade recorded significant activity as Chinese state trading firms Sinograin and COFCO executed purchases of roughly 1 million tons of U.S. soybeans (14 to 16 cargoes) for October and November delivery. The deal involved premiums of $3.03 per bushel over the November Chicago Board of Trade contract for Gulf shipments and $3.00 for Pacific Northwest ports. The purchases followed a 5.2% decline in benchmark soybean prices and precede President Xi Jinping’s scheduled U.S. visit in September, bringing China’s cumulative annual U.S. soybean purchases above 4 million tons toward its 25-million-ton annual commitment.
Domestically, weather conditions continue to weigh on crop potential. The U.S. Department of Agriculture lowered its corn condition rating for a third consecutive week to 61% good-to-excellent following prolonged heat and dryness across key Midwest growing regions during pollination. Soybean ratings held steady at 63% good-to-excellent, with drought currently affecting 29% of corn acreage and 26% of soybean acreage. Spring wheat ratings offered a rare bright spot, improving two points to 55% good-to-excellent as harvest reached 5% completion.
Metals: Trafigura Holds Large Zinc Position as Rio Tinto Bides Time on M&A
In metal markets, benchmark London Metal Exchange three-month zinc surged to $3,703.50 per ton—its highest level since August 2022. Exchange data revealed that available (on-warrant) LME zinc stocks dropped to 73,850 metric tons, equivalent to just two days of global consumption. Commodity trader Trafigura was identified as one of three entities holding dominant warrants and cash contracts, triggering acute supply availability concerns and driving cash contracts to a $60-to-$73 per ton premium over three-month futures.
On the corporate front, the six-month standstill rule preventing Rio Tinto from making an unsolicited takeover approach for Glencore expires this week. However, Rio Tinto Chief Executive Simon Trott is eschewing a potential $200 billion mega-merger to focus on internal restructuring, targeting over $10 billion in divestments ($5 billion by year-end). While Glencore’s stock rally (+33% year-to-date versus Rio’s +18%) alters merger economics, Glencore continues investor outreach in Australia following initial governance and coal-exposure objections to potential tie-ups.
