Statistical concept and methodologyMethodology: The Net Barter Terms of Trade Index (base year 2015 = 100) is calculated as the ratio of an export price index to an import price index, multiplied by 100. This index measures the rate at which a country can exchange its exports for imports. A value greater than 100 means the terms of trade have improved relative to the base year, allowing the country to obtain more imports for a given level of exports. Conversely, a value below 100 indicates that the terms have worsened. Export and import price indexes are derived from unit value data or sampled transaction-level data, depending on country-specific reporting practices. The price indexes may be computed using fixed or chain-weighted methods. To ensure temporal comparability, the export and import series are indexed to a common base year (2015 = 100). The terms of trade index is sensitive to fluctuations in global commodity prices, exchange rate movements, and changes in trade composition. It is used to assess trade gains or losses, especially for countries reliant on exports of primary commodities. Although it does not capture changes in volumes traded, it provides insight into the relative value received for exports. Policymakers and researchers may use this indicator to monitor competitiveness and evaluate exposure to external shocks.
