Terms of Trade

The ratio between a nation's export prices and its import prices.

Terms of Trade (TOT) is a macroeconomic metric that represents the ratio of a country's export prices to its import prices. It measures the relative purchasing power of a nation's trade, showing how many units of imports the country can buy for every unit of goods or services it exports. A rising TOT indicates that a country can purchase more imports for the same volume of exports, while a falling TOT means it must export more to purchase the same volume of imports. To calculate the Terms of Trade, economists divide an index of export prices by an index of import prices and multiply the result by 100. This index-based approach allows analysts to track changes in purchasing power over time relative to a chosen base year. Changes in the TOT are heavily influenced by global commodity prices, exchange rate fluctuations, and structural shifts in domestic productivity. For equity and currency investors, the Terms of Trade is a vital indicator of national economic health and corporate profitability. A rising TOT often strengthens the domestic currency and boosts national income, which can benefit domestic-focused equities. Conversely, a deteriorating TOT can signal margin compression for manufacturers reliant on imported raw materials, rising domestic inflation, and potential downward pressure on the nation's currency.

If Country A's export price index is 120 and its import price index is 105, its Terms of Trade is calculated as (120 / 105) 100 = 114.3. This means Country A's terms of trade have improved by 14.3% relative to the base year, allowing it to purchase more imports with its export revenues.
