Platinum lost roughly USD 52,710 on a single short futures position in early 2026, even as analysts predicted a market surplus. That loss, documented in a sponsored TradingView case study by analyst account mintdotfinance, is the sharpest illustration of a wider pattern: three industrial metals entered 2026 with genuine supply problems, and their prices then moved in three different directions.

By the end of 2025, platinum had recorded three consecutive years of deficits, copper mines were struggling with major disruptions, and China's aluminium production was approaching its 45-million-tonne capacity ceiling. Yet in 2026 the divergence between futures prices and physical availability became the defining feature of these markets.

What happened to platinum?

In November 2025, the World Platinum Investment Council (WPIC, the industry's supply-and-demand research body) forecast a 692 koz (thousand troy ounces) deficit for 2025, but expected the market to swing to a small 20 koz surplus in 2026. The metal ignored that call. Platinum surged to a record high in January 2026, gaining approximately 84% by 26 January, fuelled by tight physical supply, investor interest, broad precious-metals strength and speculative buying.

The reversal came fast. Hawkish Federal Reserve expectations and the Iran war lifted the dollar and bond yields. ETFs (exchange-traded funds holding the metal) recorded 234 koz of outflows in Q2. WPIC then revised its 2026 outlook three times: to a 297 koz deficit in May 2026, then to a 265 koz surplus by September. Note the whiplash — a single forecaster moved nearly 600 koz across two estimates. Yet stocks remain tight, covering just 3.4 months of demand.

The case study's short platinum trade, entered at 1,551.50 and exited at 2,605.70 on 50 contracts, lost about 68% of notional value. The lesson is uncomfortable: a correct surplus thesis, timed against a physical squeeze, still produced a forced exit.

How did aluminium escape its deficit?

ING, writing on 8 December 2025, projected a 200-kilotonne aluminium deficit for 2026, citing China's 45 million tonne capacity cap and a prolonged outage at Century's Iceland smelter. It also flagged a risk: a potential March 2026 shutdown of South32's Mozal smelter in Mozambique would widen the projected deficit from 200kt to 600kt.

The Iran war then disrupted Gulf smelters and pushed COMEX aluminium toward USD 3,800 per tonne by early June. The premium did not last. Higher Chinese exports, growing Indonesian production and expectations of smelter restarts offset the lost Gulf supply. In July, ING cut its projected 2026 deficit from 1.8 million tonnes to 1.2 million tonnes — a revision worth noting, since the December forecast had been 200kt; the bank's numbers moved dramatically as the war premium inflated, then deflated.

A long CME aluminium futures position from the case study, entered at 2,906 and exited at 3,167.50 across 25 contracts, returned USD 6,537.50, a 9% gain on notional value.

Why did copper rally into a surplus?

In October 2025, the International Copper Study Group (ICSG, an intergovernmental market-monitoring body) forecast a 150-kilotonne refined copper deficit for 2026. By October 2026 it had reversed this to a 104-kilotonne surplus, crediting weaker demand and higher secondary (recycled) supply.

Prices told a different story. Copper rallied through September as mine disruptions and expectations of U.S. import tariffs encouraged stockpiling in American warehouses, tightening supply everywhere else. The retreat came as the U.S. tariff premium narrowed and, by late October, concerns over AI-related demand weighed on sentiment — copper posted its first monthly loss since June.

What does 2027 look like?

Copper and aluminium are forecast to move into surplus; platinum is not. Cochilco, Chile's state copper commission, expects global mine production to rise 3.4% to 24.08 million tonnes in 2027, with the refined surplus widening to 215,000 tonnes, or 0.8% of consumption.

CRU, a commodities consultancy, forecasts a 1.4 million tonne aluminium surplus in 2027. Middle Eastern production is projected to recover from 4.8 million to 6.4 million tonnes, while Indonesian output — backed by Chinese investment — is expected to more than double to 3.2 million tonnes.

Platinum remains the outlier. WPIC forecasts a structural 368 koz deficit in 2027: mine supply falling 0.5% on lower South African output, industrial demand rising 4.6%, total demand up 1.7% to 7,801 koz against total supply growth of just 0.8% to 7,433 koz. Given WPIC's 2026 revision history, readers should treat these figures as direction, not arithmetic.

What does this change for industrial buyers?

The through-line is that financial sentiment — rates, positioning, geopolitics — drove futures prices while physical availability followed its own logic of disruptions, inventories and trade policy. The December Federal Reserve meeting, Middle Eastern smelter restarts, the U.S. refined copper tariff decision and WPIC's next platinum update are the markers to watch. For anyone hedging or buying physical metal, headline prices are the least reliable signal; physical premiums, exchange inventories and regional supply flows offer the clearer picture.
