Research topic

Critical metals and the energy transition

The green transition makes lithium, cobalt, copper and nickel strategic commodities. We study how their markets connect to energy markets, how far they have become financialized and whether their prices show speculative bubbles.

Main questions

How strongly are lithium and oil prices linked, and do volatility shocks spill over between them? Have critical metals become financialized assets? Can we detect and anticipate speculative bubbles in metal prices? How dependent is the green transition on fossil fuels?

Methods

Bubble-detection tests (GSADF, LPPLS), dynamic correlations and correlation networks, volatility spillover models and machine-learning classifiers with explainability tools.
