JPMorgan: Total Commodity Positioning Drops to $2 Trillion as Copper Net Longs Buck the Trend with $5 Billion Increase
nashnova research
Global commodity futures open interest dropped $54 billion week-on-week to roughly $2 trillion as of September 25, dragged down by a $47 billion energy sell-off; yet copper net longs bucked the trend, expanding by $5 billion on a triple supply-risk thesis.
Why did total open interest shrink by $54 billion in one week?
Energy was the main drag: $47 billion gone in a single week, split roughly between $24 billion in net fund outflows and a sharp drop in oil and gas prices.
This means → the drawdown was not purely a flight of capital — falling prices mechanically shrank the dollar value of existing positions, roughly half and half.
Precious metals also weakened: COMEX gold managed-money net longs fell 5,700 contracts to 127,000, pushing precious-metals open interest to $303 billion — a six-week low.
Why is copper attracting fresh longs while everything else retreats?
Base-metals open interest rose 1% (+$3.2 billion to $242 billion); investor net longs jumped $5.4 billion, with copper alone accounting for roughly $5 billion.
In plain terms = the entire commodity complex is contracting, yet money is piling into copper — it is virtually the only asset class being chased.
JPMorgan flags a triple supply risk for copper: ① diesel shortages in South America hitting mine operations ② El Niño–driven drought in Southeast Asia and Zambia, plus heavier rainfall in Chile and Peru ③ a potential strike in Chile.
This reflects a supply-side bet: the longs are not pricing a demand surge — they are front-running rising odds of supply disruption.
Will natural gas be tight this winter?
TTF prices plunged 9.4% in the week; natural-gas open interest fell 5% to $235 billion, with net outflows of $3.4 billion.
Yet JPMorgan spotted an unusual signal: QatarEnergy LNG carriers are increasingly going "dark" — switching off tracking transponders — when transiting the Strait of Hormuz. At least 7 dark transits out of the Gulf were recorded in September, all heading to Asia.
In plain terms = traffic is up from zero in August, but still far below normal. As long as the strait remains partially blocked, winter gas supply is at risk.
JPMorgan holds its call: winter natural gas will be tight, prices elevated, volatility high.
Could a U.S. diesel export ban actually work?
U.S. diesel prices have hit all-time highs; inventories are at their lowest-ever September level, reviving calls to restrict exports.
JPMorgan's take is nuanced: a 30-day export ban paired with a Jones Act waiver could deliver better-than-expected short-term results — rapidly rebuilding stockpiles and compressing domestic diesel prices and crack spreads.
This means → there is a catch with an expiry date. Once inventories normalize, the ban would undercut U.S. refining capacity, and economic viability erodes. In plain terms = an effective painkiller in the short run, but harmful if taken too long.
Does the U.S.-China trade deal move the needle for agriculture?
Agricultural open interest was roughly flat at $427 billion.
A newly formed U.S.-China trade committee agreed to slash tariffs on $30 billion of goods on each side to about 1% MFN rates — covering U.S. farm products but excluding soybeans.
This means → U.S.-origin farm goods become more competitive with Chinese private buyers, but soybeans — the single largest item in bilateral agricultural trade — are left out.
JPMorgan sees limited incremental upside from the recent summit, in line with prior expectations.
What should markets watch next?
JPMorgan economists still expect a cyclical upturn in H2 2026 with strong growth; PMI gains are spreading from tech into other sectors.
The commodity market's two key checkpoints: whether copper's triple supply risk materializes, and whether winter gas supply-demand tightens as forecast.
In plain terms = the macro backdrop is improving, but the commodity story is not just about demand — supply-side surprises are the biggest variable ahead.
