Welcome to the Bauxite Index
The Bauxite Index builds on over two decades of CM Group’s in-depth market analysis and price assessment, offering the industry’s most trusted view of global bauxite value. First launched as the world’s original Value-in-Use (ViU) adjusted bauxite price index, CBIX, it has since evolved to feature two key benchmarks: ABIX (54% alumina, 9% silica boehmitic bauxite) and GBIX (45% alumina, 3% silica gibbsitic bauxite), reflecting price dynamics across major export hubs such as Australia and Guinea.
With the introduction of the BPI Calc App, users can now instantly calculate ViU-adjusted delivered prices tailored to their specific bauxite grades, refining costs, and destination markets, putting CM Group’s trusted analytics directly at their fingertips.

The Bauxite Index provides independent, value-in-use adjusted reference prices for the global bauxite trade, including the ABIX — a 54% alumina, 9% silica boehmitic bauxite — and the GBIX, representing a 45% alumina, 3% silica gibbsitic bauxite. Together, they offer clear insight into market trends and pricing dynamics across key supply regions.
