Influence of Australian coal export on A$/US$ exchange rate: A longitudinal study

This paper investigates the contribution of Australian coal export to determine the exchange rate of Australian dollar with the US dollar. The quarterly data of Australian coal export and the Australian dollar exchange rate from 1992-2009 are employed to measure the influence of Australian coal export on A$/US$ exchange rate. This study finds that the Australian coal export has a positive relationship with the exchange rate of A$/US$ and their relationship is becoming stronger. The findings of this research suggest that the volume of Australian coal export contributes about 8% to determine the exchange rate of A$/US$ between the period of 1992-2009. The results of this analysis confirm that for each one million tonnes export increase of Australian coal, the Australian dollar value against the US$ increases by 0.002450 USD.
