The Reserve Bank of Australia published preliminary estimates for its March Index of Commodity Prices showing a 2.6 per cent rise in SDR terms on a monthly average basis, following a 1.6 per cent increase in February. In Australian dollar terms, the index increased by 2.1 per cent in March. All three subindices (non-rural, rural and base metals) increased over the month. Over the past year, the index rose 12.8 per cent in SDR terms (3.8 per cent in Australian dollar terms), with higher prices for gold, lithium, coking coal and rural commodities offsetting declines in iron ore and alumina. For the most recent months, export prices for iron ore, coking coal, thermal coal and LNG use preliminary estimates based on market information; on a spot-price basis for bulk commodities, the index increased by 3.5 per cent in March in SDR terms and was 16.5 per cent higher over the year.
