Base metals like copper, aluminum, and iron are examples of large volumes of raw material used in modern-day infrastructure and construction. On the other hand, technology metals or critical minerals (for example, cobalt, lithium, and rare earth elements) are specialty materials required for advanced green technology development. The distinctive features of technology metals are scarcity of occurrence, uneven distribution on Earth, and the fundamental importance for advanced technological applications (Villa Gomez et al., 2022). In the past, there was a weak association between the prices of these materials; nowadays, the dynamics of the pricing process diverges rapidly due to differences in demand forces, market structure, and geopolitics.
The main factor causing divergence is the green energy shift. Base metal prices correlate with conventional economic cycles, industrial development, and GDP growth. On the contrary, technology metals are mostly affected by a quick shift towards low-carbon energy scenario in the long run (Watari et al., 2018). Due to the increasing regulation of deployment of electric cars, wind power plants, and energy storage systems, the demand for battery and magnets becomes inelastic. Hence, prices of such elements as lithium and neodymium sometimes deviate from regular economic cycles leading to booms.
Supply limitations and difficulties associated with extraction add further emphasis to the pricing disparity noted. Base metals enjoy a number of supply advantages in terms of geographic diversification of supplies, scalable manufacturing capacity, and well-developed mining industry, all of which ensure relative flexibility in adjusting the supply level to changes in demand. In the case of technology metals, significant geographic concentration of supply and geophysical scarcity are typical. The expansion of the primary supply is very inflexible, with many technology metals extracted either as co-products in mining of base metals or via innovative and unconventional technologies involving recovery of resources from acid mine drainage (Larochelle et al., 2021).
Market liquidity and information transparency also differentiate between the two metal categories. Base metals are actively traded on liquid exchanges such as London Metal Exchange (LME), and have an effective mechanism of price discovery and hedging implemented. In contrast, technology metals are traded in smaller volumes, and most often, through obscure bilateral agreements. Lack of transparency makes the pricing of technology metals prone to speculations and abrupt market shocks. To reduce the effects of the volatile pricing, industries have to resort to innovative ways of obtaining secondary supplies, for example, technospheric mining of non-ferrous metallurgical slags (Lim et al., 2024).
Also, the geopolitics has an outsized effect on technology metal pricing than on the pricing of base metals. The concentration of the capacity to refine critical minerals in a few countries creates considerable risk premia in technology metal prices due to export restrictions, tariffs, and diplomatic conflicts. Though base metals may face trade obstacles, they rarely see the weaponization of supply chains as in the case of rare-earths. In order to overcome the pricing vulnerabilities caused by geopolitics, policies have been implemented to create a circular economy that will monitor critical minerals until they reach their final destination to obtain domestic secondary supplies (Shimizu & Owada, 2024).
Overall, the pricing of technology metals has become significantly different from that of base metals. Whereas the former can be used to indicate economic conditions, the latter is governed by highly volatile factors of aggressive green-technology regulations, inelastic supply chains, and geopolitics. To ensure stability in the pricing of technology metals in the future, some essential changes should be made in the management of global resources, investment in recycling facilities, and deliberate steps towards creating a circular economy.
