Hence, their value in domestic currency should be relatively stable (a devaluation would reduce commodity prices). However, if there is fear of floating, exchange rates do not adjust and commodity prices in local currency also fall. Their
results show that those prices in local currency are more volatile than exchange rates, especially for emerging economies. Besides, in most cases, the correlation between those two variables is small and not significant, which means that exchange rate does not play its role as a shock absorber, probably a result of the fear of strong fluctuations.
