Rio Tinto Shares Gain on Copper Strength and Year-End Rally

Rio Tinto shares climbed nearly 1% on December 22, 2025, as commodity markets rallied into the year-end. The S&P/ASX 200 rose 0.9%, buoyed by gains in major mining stocks, including BHP and Fortescue, while copper prices surged above $12,000 per tonne. London-traded Rio Tinto plc (RIO.L) also posted a 1.33% increase, closing NEAR 5,916 pence. Analysts attributed the session to a delayed 'Santa Claus rally,' reflecting strong risk-on sentiment in materials.

Copper has emerged as a key driver for Rio Tinto’s stock, reaching near-record highs amid persistent supply deficits. The metal’s tightness and AI-driven demand are fueling Rio’s growth narrative, shifting focus beyond its traditional reliance on iron ore. CEO Trott’s strategy—centered on cost cuts, divestments, and operational simplification—aims to strengthen shareholder returns. Long-term projects like Pilbara’s Rhodes Ridge underscore production continuity, despite geopolitical and energy risks.

The broader uptick leaves markets debating whether current commodity strength marks a temporary bounce or the start of a sustained cycle. For Rio, resilient iron ore and booming copper prices have bolstered investor confidence.
