Abstract

Given the significant concerns of currency devaluation and level of inflation in Indonesia, we measure their
dynamic connectedness and cross-quantile dependence with prominent export items such as crude palm oil price
and coal price. To this end, we apply the frequency connectedness approach and Cross-Quantilogram approach to
measure volatility spillover utilising daily data from 2002 to 2021. The frequency connectivity analysis coincides
with our proposition that exchange rate and inflation substantially respond to coal and crude palm oil prices.
Next, we apply the cross-quantilogram framework to examine the cross-quantile dependence between exchange
rate and other variables to capture the spillovers between these markets considering a wide range of market
conditions. Our empirical analysis demonstrates that exchange and inflation are connected during extreme
market volatility when they boom together. The exchange rate responds to palm oil price at the extreme quantile
of the exchange rate in long-term horizons. The degree of connectedness between exchange rate and coal price is
profound at the higher quantile in the long run horizon while it dissipates in the short run. Our findings provide
important policy implications to the energy and monetary authority of Indonesia.
