In the Second Half of 2026, Commodities Enter an Era of 'High-Frequency Black Swans'
Heading into the second half of 2026, Citigroup warns that the commodities market is entering an era of "High-Frequency Black Swans," where extreme, paradigm-shifting events are becoming increasingly common. The report outlines major tail-risk scenarios beyond its baseline forecasts.
The highest-impact scenario is a prolonged US-Iran conflict disrupting Gulf energy infrastructure and key shipping chokepoints, potentially causing a sustained 5-10 million barrel per day oil supply deficit and pushing crude prices above $200/barrel. Other geopolitical risks include stricter sanctions on Russian energy, which would hit gas markets harder than oil, particularly liquefied natural gas (LNG).
A high-probability risk is a global scramble by governments to stockpile critical minerals. Large-scale strategic buying, particularly of copper, could drive prices above $20,000/ton. For gold, Citigroup sees near-term downside risk towards $3,800/ounce before a potential long-term rally to $6,000/ounce, supported by central bank demand and de-dollarization trends.
An extreme El Niño weather pattern poses a medium-probability, high-impact threat to agriculture, potentially sending cocoa prices back to $10,000/ton and sugar above 20 cents/pound. The AI boom presents a dual-sided risk: a bust would hurt metals and power demand, while sustained growth would exacerbate structural deficits in copper and aluminum.
Two other significant scenarios are the finalization of Russia's Power of Siberia 2 gas pipeline to China, which could depress Asian LNG prices to $5-6/MMBtu in the 2030s, and an extreme application of the Monroe Doctrine blocking Americas oil exports, which could create a price split with global benchmarks soaring above $100/barrel while regional benchmarks crash.
The overarching conclusion is that traditional supply-demand analysis may fail in a market where such high-impact, interconnected shocks are becoming more frequent.
