Commodity Price Volatility: Rio Tinto's financial performance is highly sensitive to the fluctuating global prices of key commodities such as iron ore, aluminum, and copper. A significant and sustained downturn in these prices can severely impact revenue, profitability, and cash flow.

Environmental, Social, and Governance (ESG) Incidents: The company faces risks related to environmental damage, carbon emissions, water usage, and community relations. Past incidents, like the destruction of the Juukan Gorge caves, highlight the potential for significant reputational damage, legal penalties, and operational disruptions.

Regulatory and Political Risks: Operations span multiple jurisdictions, exposing Rio Tinto to changes in mining laws, royalties, taxes, export restrictions, and the risk of resource nationalism or political instability in host countries, which could lead to increased costs or asset impairments.
