The world's 50 most valuable mining companies lost $264 billion in market value during September due to inflation fears linked to oil prices. Oilprice.com reported that the group's total market capitalization ended the month at $2.26 trillion, marking the second-largest monthly decline recorded since 2019.

Rising oil-driven inflation pushed bond yields to their highest levels since 2008 and prompted the Federal Reserve's first interest rate hike in three years. This hawkish pivot negatively impacted gold and mining equities, dragging valuations lower even as the sector remains above its total valuation from the end of 2025.
