Iran: Terms of trade, base year = 2000: For that indicator, The United Nations provides data for Iran from 2000 to 2016. The average value for Iran during that period was 203.37 percent with a minumum of 100 percent in 2000 and a maximum of 395.07 percent in 2014. See the global rankings for that indicator or use the country comparator to compare trends over time.
The terms of trade for Iran are calculated as the value of its exports as percent of the value of its imports. An increase in the terms of trade means that the value of exports is increasing relative to the value of imports. The country can afford to buy more imports with the revenue from its exports. For example, an increase in the price of oil increases (improves) the terms of trade for the oil-exporting countries and lowers it for the other countries.
Definition: Net barter terms of trade index is calculated as the percentage ratio of the export unit value indexes to the import unit value indexes, measured relative to the base year 2000. Unit value indexes are based on data reported by countries that demonstrate consistency under UNCTAD quality controls, supplemented by UNCTAD's estimates using the previous year’s trade values at the Standard International Trade Classification three-digit level as weights. To improve data coverage, especially for the latest periods, UNCTAD constructs a set of average prices indexes at the three-digit product classification of the Standard International Trade Classification revision 3 using UNCTAD’s Commodity Price Statistics, international and national sources, and UNCTAD secretariat estimates and calculates unit value indexes at the country level using the current year's trade values as weights.
