Commodity markets are flashing a signal that can no longer be ignored: the structural bull cycle has entered a new phase, and the volatility ahead will be far more intense.

Jeff Currie, former head of commodities research at Goldman Sachs and now co-chairman of Abaxx Markets, issued a stark warning across a series of ten posts on social media platform X, arguing that the convergence of physical supply bottlenecks, currency debasement, and policy intervention are hallmarks of a structural commodity bull cycle. "Wake up, folks. Commodities are telling you something, and yesterday the US Treasury confirmed it," he wrote, adding that he has already established positions in gold, silver, and agricultural products.

The market signals are already dense: diesel crack spreads have broken above $100 per barrel for the first time, London copper prices have surged past $14,000 per tonne, gold has climbed to $4,510 after rising 4% in a single day, silver has gained 5%, the Bloomberg Agriculture Spot Index continues to advance, and the Quantix Commodity Index has hit an all-time high. Meanwhile, US Treasury Secretary Bessent announced a significant increase in long-dated Treasury buybacks this week, sending the dollar sharply lower and providing additional tailwinds for commodities.

Fiscal intervention disrupts normal feedback mechanisms

Currie characterizes the macro backdrop of this commodity rally as a systemic failure. He points out that just one day after 30-year Treasury yields touched 5.32%, their highest level since 2007, Treasury Secretary Bessent announced a doubling of long-dated Treasury buyback operations, a mere two weeks after the previous quarterly schedule was published.

In Currie's view, this is merely the latest in a series of interventions, following the drawdown of the Strategic Petroleum Reserve (now below 300 million barrels), dollar support for foreign holders in Japan and the Gulf region, and the first foreign exchange intervention in euros and yen since 1998.

More critically, these interventions have severed the normal self-correcting mechanisms of commodity markets. Currie explains that under normal conditions, surging commodity prices would push yields higher, thereby suppressing demand and enabling self-correction. However, current financial repression has "cut the brake lines": scarcity drives inflation higher, suppression policies prevent the market from responding normally, and the lack of response further amplifies the scarcity premium. He summarizes this logic as: "Scarcity is re-pricing the numerator, while repression is debasing the denominator."

Record diesel crack spreads signal comprehensive physical bottlenecks

Currie identifies the diesel market as the core lens for understanding this commodity bull run. Diesel crack spreads have settled at $102.20 per barrel, breaking through $100 for the first time in history, representing four to six times the normal range, and setting records on five of the past six trading sessions.

He attributes this situation to a global shortage of refining capacity: ongoing Ukrainian strikes on Russian refineries, attacks on Middle Eastern facilities in Iran, and years of chronic underinvestment have collectively reduced global refining runs by approximately 5 million barrels per day.

Currie emphasizes that diesel forms the floor for the entire commodity complex: "Every commodity is dirt plus diesel." Container shipping, agricultural machinery, rail locomotives, mining trucks, and fertilizer production all depend on diesel, and this energy input cost sets a price floor for metals, grains, and virtually all other commodities. This explains why the Quantix Commodity Index has reached record highs even while crude oil prices remain $30 below their peak. He warns that the pass-through to trucking, food, and producer prices "is just beginning."

Supply bottlenecks are global in scope, with no redundancy left in the system

Currie lists a series of simultaneously tightening global supply nodes, arguing that these bottlenecks are beyond the capacity of any Washington policy tool to address.

On the energy front, the Strait of Hormuz has been constrained for six months, Red Sea shipping continues to require diversions, Russian refining capacity remains under sustained attack, all three ports at Novorossiysk in the Black Sea are closed, and 97% of Azov-Black Sea export capacity is offline during peak season.

On agriculture, Rhine River water levels have fallen to historic lows due to heatwaves, Panama Canal draft limits have been reduced to 47.5 feet, the USDA has cut its US corn yield estimate to 180.7 bushels per acre with ending stocks reduced by 15%, and corn prices have risen 10% in a single week.

Currie also notes that NOAA forecasts an 81% probability of a strong El Niño event by year-end, which would further intensify pressure through Panama drought, weakened Asian monsoons, and a narrowed Brazilian planting window. He concludes: "There is no redundancy left in the system."

Treasury supply pressures reinforce the debasement narrative

Currie also points to structural pressures in the US Treasury market as another important support for the commodity bull market.

Data shows that foreign holders reduced their Treasury holdings in June, led by Japan, China, and the UK; the July fiscal deficit reached $432 billion, interest expense hit $1.1 trillion, and total US Treasury debt is approaching $40 trillion. Meanwhile, bond issuance for hyperscale AI capital expenditure is competing with Treasuries for the same pool of savings, and marginal buyers are waiting for higher yields to enter the market.

Currie characterizes the Treasury's buyback operations as "a managed, failed auction," predicting that the bond market will gradually discover over the next six months what the physical market already knows.

Conclusion: go long and buckle up

Currie's final recommendation is straightforward. He argues that in an environment where scarcity and debasement logic run in parallel, commodities are the only asset class that can benefit from both ends simultaneously: refined products, grains, and freight correspond to the scarcity logic, while gold corresponds to the debasement logic.

He concludes with a single sentence: "Go long and buckle up: the next phase will bring higher volatility and higher highs across more markets."
