LME copper spot traded at $13,170 per metric tonne on July 1, according to MacroMicro data, consolidating in a range roughly 9% below the all-time record of $14,527.50/t set on January 29, 2026. COMEX copper futures peaked at $6.58/lb that same month before pulling back. The market has spent the second quarter oscillating between structural supply anxiety — mine disruptions at Grasberg and Codelco have removed an estimated 800,000 tonnes of annual supply, according to J2T analysis — and the weight of historically elevated visible inventories.
The inventory picture is dominated by COMEX warehouses, where stocks now exceed 503,000 tonnes, up from less than 100,000 tonnes a year ago. That 400% build reflects pre-tariff stockpiling ahead of the US Section 232 investigation into refined copper imports, not underlying demand strength. LME inventories stand at roughly 184,300 tonnes (a nine-month high), and SHFE warehouses hold 248,911 tonnes. Combined visible stocks exceeded 1.3 million tonnes in March 2026, per S&P Global Market Intelligence — a level that 'adds near-term pressure but does not resolve structural tightness.'
The US Commerce Department's June 30, 2026 tariff review is the binary catalyst markets are watching. Goldman Sachs Research frames the scenarios clearly: a definitive tariff decision should signal the end of US stockpiling, allowing LME prices to decline toward the firm's $10,000–11,000/t fair-value range as COMEX destocking releases metal back to the global market. A delay beyond 2026, by contrast, would be bearish for the premium narrative — the probability of a tariff fades, and attention shifts to a well-supplied global market. Goldman raised its 2026 global surplus forecast to 300,000 tonnes from a prior 160,000 tonnes, arguing high prices are dampening demand growth and lifting scrap supply.
JP Morgan Global Research sees the opposite: a refined copper deficit of roughly 330,000 tonnes in 2026, with an average price near $12,075/t and a potential peak of $12,500/t in the second quarter. The divergence is not semantic. One bank models a market that needs destocking to find equilibrium; the other models one that is already tight and will tighten further. JP Morgan's deficit thesis leans on the supply-side damage: Codelco's $24 billion debt load and declining ore grades, Grasberg disruptions, and the multi-year lead time on new mine capacity. S&P Global projects a cumulative copper concentrate deficit of roughly 3 million tonnes by 2036, driven by limited new mine additions and rising costs.
On the demand side, China remains the gravitational center at roughly 60% of global consumption. Chinese buyers are 'dip-buying' at lower price levels, per J2T, but end-use demand in property-linked construction has been soft. S&P Global estimates global refined copper demand growth slowing to 2.3% in 2026 from 4.1% in 2025, as high prices and weaker macro conditions temper growth. The SHFE premium over LME in early 2026 reflected supply-side pressure from tariffs and logistics rather than strong domestic Chinese demand — a key complexity Expert Market Research flagged in its June 2026 report.
The longer-term narrative remains structurally bullish across all major analysts. Goldman Sachs sees demand outpacing supply from roughly 2029 onward, forecasting LME copper at $15,000/t by 2035, above the industry consensus. S&P Global's concentrate deficit model points the same direction. Grid and power infrastructure, AI data-center build-out, renewables, and defense spending are repeatedly cited as the demand drivers that current mine pipelines cannot match. The International Copper Study Group (ICSG) has not yet published its mid-year 2026 balance, but its prior outlook pointed to a market moving from small surplus toward balance.
The Strait of Hormuz closure has added a new layer of macro risk. Energy price spikes reduce economic growth — J2T estimates a 10% Brent crude rise strips roughly 0.19 percentage points from copper demand growth — and affect mine operations through higher energy costs. Copper has historically troughed roughly 25% below peak during major macroeconomic shocks, a reference point for buyers modeling worst-case scenarios.
The tariff decision changes everything, and the window for positioning is now. If a definitive Section 232 tariff on refined copper imports is announced, expect COMEX destocking to release 300,000–500,000 tonnes into the global market over 6–12 months. LME prices could decline toward $10,500–11,500/t. That scenario favors spot buying and shorter contract tenors for the second half of 2026. If the decision is delayed into 2027, the uncertainty premium stays embedded, and LME copper likely holds above $12,000/t. In that case, lock 6-month indexed term contracts now rather than waiting for clarity that may not arrive. For buyers with COMEX-linked physical contracts: the LME-COMEX dislocation remains wide. Consider switching price references where contract language permits, or negotiate a blended index. For long-term strategic buyers: the 2029–2035 structural deficit thesis is the strongest consensus in a decade across major banks and research houses. If your 2027–2028 supply agreements are up for renewal, negotiate now. Every year of delay on mine development deepens the medium-term supply gap. Build a 12-month price scenario model with three tariff outcomes: definitive tariff by Q3 2026 (40% probability), delay to 2027 (35%), no tariff imposed (25%). Weight your contract mix accordingly.
