Over the past year, the index has increased by 21.7 per cent in SDR terms, led by higher LNG, coking coal and thermal coal prices. The index has increased by 18.1 per cent in Australian dollar terms.
Consistent with previous releases, preliminary estimates for iron ore, coking coal, thermal coal and LNG export prices are being used for the most recent months, based on market information. Using spot prices for the bulk commodities, the index increased by 0.5 per cent in August in SDR terms, to be 19.9 per cent higher over the past year.
