U.S.-China Relations
NextFin News - Copper slipped below $14,000 a metric ton on Tuesday for the first time since September, falling for a second straight session as early U.S. midterm results pointed to a possible Democratic sweep of Congress and sent risk assets lower. The move sets a short-term election-driven de-risking trade against the tighter physical market underneath the metal, and the question is which force wins.
As of midday in New York on Wednesday, the London Metal Exchange's three-month copper contract was holding losses below the $14,000 level that had broadly contained prices for the past two months. Benchmark copper fell to $6.36 a pound, down 2.78% on the day and 3.40% over the past month, even as the metal remains about 30% higher than a year earlier — a correction inside an uptrend, not a collapse.
The political trigger was immediate. U.S. stock futures slid 0.8% while Nasdaq futures fell 1.8%, and the yield on the benchmark 10-year Treasury note dropped 6 basis points to 4.906% as Democrats notched early Senate wins, including a flipped seat in North Carolina. Prediction markets signaled growing expectations of a Democratic sweep of Congress, with more than $1.48 billion wagered on the midterms. Copper, the industrial metal with the highest beta to growth sentiment, moved with equities rather than with its own supply ledger.
Yet the sell-off arrives at a moment when the metal's fundamental backdrop has rarely looked tighter. The tension defines the trade: is this a cyclical sentiment break, or the first crack in a structural bull market that has carried copper 30% higher in a year? The answer matters for every investor holding miners, utilities, or the AI-infrastructure complex that has driven the metal's rally.
The Election Channel: How Washington Moves Copper
Copper is not usually an election metal, but in 2026 it sits at the intersection of two politically sensitive trades: AI infrastructure spending and fiscal stimulus expectations. The metal's use in data centers and power transmission means any outcome perceived as threatening data-center incentives or slowing AI capital expenditure hits copper demand expectations directly.
The transmission channel is mechanical, and it runs through positioning rather than pipes. Election uncertainty triggers risk-off positioning in equities. Copper, as the most equity-correlated industrial metal, gets sold alongside stocks. Leveraged long positions unwind. A technical support level that held for two months breaks. None of this requires a single tonne of copper to change hands in the physical market. The price of a tonne of wire rod in Shanghai did not change because voters in Pennsylvania cast ballots; the price changed because a hedge fund in Connecticut reduced its gross exposure.
"Markets appear to be pricing in the possibility of a stronger-than-expected Democratic showing, which could reduce expectations for further fiscal stimulus," said Charu Chanana, chief investment strategist at Saxo in Singapore.
Chanana added that the sharper decline in Nasdaq futures reflected concerns that a shift in political control could bring greater regulatory scrutiny of AI and Big Tech, at a time when investors were already questioning elevated valuations and rising AI spending. "However, lower Treasury yields could eventually provide some relief, so the initial selloff may not necessarily be sustained," she said.
The positioning data supports the view that this is a flow-driven move rather than a fundamentals repricing. A Wolfe Research survey of more than 100 institutional investors found portfolios were not strongly positioned for any particular outcome, and investors remained skeptical that Democrats would perform as well as polling suggested. "Investors seem to have a significant dose of skepticism about whether the final outcome is going to be quite as favorable to Democrats as the polling suggests," said Tobin Marcus, head of U.S. policy and politics at Wolfe Research, noting the firm shares the view that polling is likely overstating Democratic strength.
The asymmetry in the setup matters for copper. JPMorgan's traders estimated a Democratic sweep could push the S&P 500 down about 0.5% on Wednesday, while a Republican hold on the Senate could produce a relief rally of up to 1%. If the election outcome is being discounted unevenly — stocks pricing in downside while portfolios are not positioned for it — then copper's move is a sentiment spillover, not a reassessment of the metal's supply-demand balance.
History offers a cautionary note. During midterm election years, the S&P 500 has typically averaged a 14% drawdown at some point in the second half of the year, according to BTIG's chief market technician Jonathan Krinsky. But he warned that this year's starting point is different. "The reason stocks often perform well in November during midterms is because [the S&P 500] typically is weak INTO the elections," Krinsky wrote last week. "We have the opposite setup this year." A drawdown is a volatility event, not a demand event — and copper's 30% annual gain suggests the demand trend has not broken.
The AI angle sharpens the political risk. A strong Democratic showing, especially in Texas, could add fuel to an AI-stock sell-off on the notion that more data-center restrictions would gain momentum nationally, according to analysts. Goldman Sachs strategists have said a Democratic Congress might limit data-center tax incentives, though a national moratorium looks unlikely in any election outcome. That distinction is crucial for copper: tax incentives affect the pace of the buildout, not its direction. Grid and transmission spending — the copper-intensive part of the AI infrastructure chain — is a bipartisan priority, and it continues regardless of which party holds the gavels.
The Deficit That Has Not Gone Away
While traders watched Washington, the physical market underneath copper tightened. Goldman Sachs raised its copper forecasts on October 20, projecting the metal will reach $14,700 a metric ton by the end of 2026 and average $15,400 in 2027 — up from $13,735 and $13,800 previously, increases of 7% and 11.6%. The bank now expects supply deficits outside the United States of 950,000 metric tons in 2026 and 220,000 tons in 2027, driven by weaker mine output and resilient Chinese demand.
Goldman is not alone. Morgan Stanley projects a 600,000-tonne shortfall in 2026, and J.P. Morgan sees a 330,000-tonne deficit. The bullish case rests on a simple premise: the market must draw down inventories rather than build them.
The supply side is where the structural argument is strongest. Chile's Cochilco commission expects global mine production of about 23.5 million tonnes in 2026, a rise of only 0.2% from 2025, as disruptions at major mines — Grasberg in Indonesia, Kamoa-Kakula in the Democratic Republic of Congo, and Rio Tinto's Oyu Tolgoi in Mongolia — constrain volumes. Peru's energy crisis, which prompted an emergency decree in May prioritizing household electricity over industrial users, raised the risk of power restrictions at mines. Recovery is not expected until 2027, when mine growth is forecast to accelerate toward 3%.
Trade policy has amplified the physical squeeze. The United States already applies Section 232 tariffs on certain copper products, and a proposed tariff on refined copper has pulled metal into American warehouses. Comex stocks in the U.S. reached about 718,200 metric tons on October 19, reflecting purchases ahead of potential refined-copper tariffs. The result is a market that appears well supplied on paper but is tight where it matters: Goldman analysts noted that while global inventories look ample, much of that metal is stranded in American warehouses, unavailable to the rest of the world.
On the demand side, AI data centers are emerging as a new source of copper consumption. JPMorgan estimates AI-related data centers could add around 110,000 tonnes of demand by 2026, and a clean-energy research group projects data-center infrastructure could hold more than 4.3 million tonnes of copper by 2035. This is the second-order link that election-night traders are missing: even if a Democratic Congress curbs data-center tax incentives, the buildout of grid and transmission capacity remains a bipartisan priority, and it still requires copper.
There is, however, a dissenting view on the balance. Cochilco forecasts a refined copper surplus of 225,000 tonnes this year, and the International Copper Study Group has revised its outlook as demand growth moderates and secondary production rises. The divergence between institutions is itself a signal: the deficit thesis is a consensus among Wall Street banks built on constrained supply, not a unanimous view of the market.
Cyclical Pullback, Structural Floor
The central judgment: this is a cyclical, sentiment-driven pullback superimposed on a structural supply squeeze, and the two should not be confused. Three pieces of evidence support the cyclical read. First, the move coincides precisely with equity de-risking, not with any change in mine supply or Chinese demand data. Second, copper remains 30% higher year over year even after the drop, indicating the uptrend is intact. Third, the price broke a two-month range on event-driven flows rather than on a fundamental catalyst.
History reinforces the cyclical reading. Copper has endured similar political sell-offs without breaking its long-term trend. In 2018, trade-war headlines drove the metal down more than 22% over the year even as the underlying supply story remained unchanged. In March 2020, pandemic-driven risk-off sent LME copper to $4,371 a ton, its lowest level in more than four years, down from above $6,300 in mid-January; the metal then more than doubled as fiscal stimulus and supply disruptions took hold. In 2022, recession fears pulled copper down more than 25% from its March peak by late August, yet the metal stabilized once China's reopening trade re-emerged. The pattern is consistent: copper's political drawdowns are buying opportunities when the supply ledger has not changed. What is different this time is not the politics — it is the tightness of the physical market underneath.
But the cyclical label has limits. A 950,000-ton deficit outside the U.S. does not disappear because U.S. voters went to the polls. The correct read is that the election is creating a potential buying opportunity only if the deficit forecasts hold — and they will be tested over the coming months.
The strongest counter-thesis is that the AI capex narrative itself is the bubble, and copper's 30% annual gain has priced in data-center demand that may never materialize. If AI infrastructure spending slows — as recent jitters over returns on AI investment suggest, with one chip giant issuing a weak outlook while a rival beat forecasts — then the demand side of the deficit equation weakens, and Goldman's $14,700 target looks optimistic rather than conservative. The counter-thesis has a named constituency: Cochilco's surplus forecast and the International Copper Study Group's revised outlook both imply that demand is moderating faster than the bulls assume.
That counter-argument is serious but incomplete. Even excluding AI, the supply side alone — flat mine output, aging ore grades in Chile and Peru, and years of underinvestment — supports a tight market. The AI demand is the upside option, not the base case. The base case is a deficit driven by constrained supply; the bear case requires both AI demand to disappoint and supply to recover faster than expected. Two things must go wrong for the bulls, one for the bears — and that asymmetry favors holding the structural view.
The second-order implication runs deeper than copper itself. If the election outcome reduces expectations for fiscal stimulus, Treasury yields fall — as they did on Wednesday, with the 10-year note dropping 6 basis points. Lower yields should, in theory, support copper by weakening the dollar and lowering the carrying cost of inventory. But if the yield decline reflects growth fears rather than inflation relief, the stimulus to copper is muted. This is the trap in the conventional read: a rate cut or yield drop born of recession fear is not the same as one born of cooling inflation, and copper has historically performed poorly when the Fed cuts into a slowdown. The market is not yet asking which kind of relief it is buying. That question will matter more than the election result itself.
The channel through which politics reaches the metal is therefore indirect and conditional. A Democratic sweep reduces expected fiscal stimulus, which lowers yields; lower yields support copper only if they signal disinflation rather than recession; meanwhile, any curbs on data-center incentives slow the marginal demand growth but leave the grid buildout intact. Each link in that chain is probabilistic, and the net effect is far smaller than the headline risk suggests. The market is trading the first link as if it were the last.
What to Watch
The falsifying signal for the structural-support view is specific: if copper closes decisively below the two-month range floor, roughly $13,500 a ton, and major banks cut their 2026 deficit forecasts, the thesis that this is a cyclical dip within a structural bull market is wrong. Until then, the deficit forecasts stand.
Short term, the election outcome dominates. A Republican hold on the Senate could trigger the relief rally JPMorgan's traders outlined, lifting copper back toward $14,000. Medium term, the market will watch Chinese demand data and mine-output reports for confirmation that the deficit is materializing. Long term, the structural case rests on whether data-center copper demand proves durable and whether mine supply recovers in 2027 as projected.
Scenarios:
- Base case: election uncertainty clears, copper holds the $13,500–$14,000 range, and the deficit supports a grind toward Goldman's $14,700 year-end target.
- Upside: a supply shock or stronger-than-expected Chinese demand pushes copper through $14,500 toward the $15,000–$15,400 zone.
- Downside: a Democratic sweep curbs AI incentives and global growth fears deepen, breaking the range and testing $13,000.
The election will decide Washington, but it will not decide the copper market. The deficit will.
