Global money supply and energy and non-energy commodity prices: A MS-TV-VAR approach

This paper shows that the impact of the global money supply is disproportionally high for energy than for non-energy commodities prices. An increase in the global money supply for energy commodity prices results mostly in demand-pull inflation. However, for non-energy commodity prices, an increase in global money supply results in demand-pull inflation and cost-push inflation, as energy is a critical input for non-energy commodities. We introduce a Markov Switching framework with timevarying transition probabilities to quantify this effect. This macro-econometric model accounts for periods when the global money supply growth is slow, moderate, and fast. We find that the response to global money supply shocks is higher for energy than for non-energy commodity prices. We also find heterogeneous responses for both energy and non-energy commodities across regimes.
